SCOPE OF WORK

 SCOPE OF WORK

Sub : Rehabilitation of 600 mm dia. to 900 mm dia. sewerline by

Trenchless technology.

1. Introduction:

The Sewerage Operations department of the Municipal Corporation of Greater

Mumbai proposes to carry out structural rehabilitation of sewerlines by any
suitable, proven pipe rehabilitation technique using Trenchless Technology, with
minimum trenches taken on road surface as a result of the work. The technology
offered by the bidders shall meet the deliverables mentioned under this chapter.
Considering fully deteriorated parent sewer condition, the structural liner shall be
designed to take combined loads comprising of hydrostatic loads, soil loads and
traffic loads and to act as a standalone liner/pipe in accordance with the design
procedure given in the technical specification.

The purpose of structural rehabilitation is to increase the structural strength as

well as flow carrying capacity of the Sewer to improve the hydraulic performance
and to increase corrosion resistance and in turn to enhance the useful life of the
sewer.

The following 17 sewer line stretches having total length of 10000 meters are
included in the scope of the work of rehabilitation by trenchless technology.
However, due to infrastructure works undertaken/to be undertaken by various
authorities like Metro-3, Redevelopment of B.D.D. chawl, replacement/
augmentation of sewer lines by SP/MSDP departments of M.C.G.M., few sewer
lines (to the tune of 25%) may be deleted from the scope of the work and the
quantities in B.O.Q. may thereby be reduced accordingly, without any obligation
on M.C.G.M. to replace reduced quantities by alternate sewer stretches.

percent of 88 percent of the value of the work carried out. The
remaining 12 percent being the presumptive profit of the
contractor.

a) Formula for Labour component:

VL = (0.88 R) x 30 x ( I – IO)
100 IO

b) Formula for Material component :

VM=(0.88 R x 70- C) x (W – W O)
100 WO

value of ‘C’ shall be inclusive of permitted wastages as / if
mentioned in specifications.
ii) The basic rate for the supply of controlled material shall be
inclusive of all the components of cost of materials excluding
transport charges incurred for bringing the material from place of
delivery to the site.
Computations based on the above formula will be made for the
period of each bill separately and reimbursement will be made to

any sugar or an excess of acid, alkali or salt, that water should not be used.

3.2 Measures for reducing water demand during construction

To avoid wastage of curing water, following guidelines are to be followed:
1. Curing water should be sprayed on concrete structures; free flow of water
should not be allowed for curing..
2. Concrete structures should be covered with thick cloth/gunny bags and
then water should be sprayed on them. This would avoid water rebound and will
ensure unstained and complete curing.
3. Ponds should be made using cement and sand mortar to avoid water
flowing away from the flat surface while curing.
4. Water ponding should be done on all sunken slabs, this would also
highlight the importance of having an impervious formwork.

4.0 Construction wastewater management

Wastewater generated from the site during the construction contains suspended
materials, spillage and washings from the various areas which can be hazardous
and should not be mixed with the sewage water or allowed to percolate into the

The relative humidity is generally between 48% and over 90% highest being in the
monsoon period from June to September. Some of the suburban areas are reclaimed
land and the water table is generally high.

The city is well connected to other Indian and international cities by air and land.

1.3.2 Geology and Soil

The Mumbai area was formed geologically, through volcanic effusions and deposition
of marine strata. The area also has tuffs, tuffaceous breccias and volcanic ashes
which are all much softer than the basalt trap rock.

Mumbai Soil essentially consists of clay, with the particular nature of the top soil
varying depending upon the location. However, since as more than 50% of the area
has been raised through reclamation, the surface material often reflects the nature of
the fill material used. In general, a 1-1.5m topsoil / fill layer, overlaying clay of depth
varying between about 3.5 m to 7.0 m. The clay layer is followed by a layer of ‘murrum’
which is supported, in turn, on weathered basalt rock, tuffs or tuffaceous breccias. In

- 198 -
reclaimed areas, the top soil may vary in depth from 1m to 3m and generally
comprises fill materials varying from loose boulders and pieces of weathered rock, to
well compacted clay. In general, the ground conditions for most of the area can be
classified as good with respect to the construction of sewer lines. It may be possible to
get rock at very shallow depth and sewers in such cases might have a rock.

Contractor shall make reference to detailed geological survey maps for Mumbai areas
from the relevant authorities for further details on the ground conditions.

1.3.3 Tidal Data

Sea water levels are recorded in the Automatic Gauge Recorder at Apollo Bunder. The
tidal cycle is twice daily, but because of an appreciable diurnal element, unequal tides
are produced on most days causing wide variation in extreme levels. This variation is
sufficient to cause to lowest high water to be lower than the highest low water level.
Statistical studies indicate that:

1. All high tides exceed +2.70 m.

2. About 5% of all high tides would be less than +3.20 m.

There is a considerable impact of the tidal effects to the sewage conveyance system.
Since there are believed to be a number of interconnections between sewage
conveyance system and storm water drains, sea water finds its way to sewers under
high tide conditions.

1.3.4 Flooding Spots

Flooding can occur in the city area as a result of a number of factors including rainfall,
rainfall in conjunction with high tides and Storm Drain blockages or collapses. There
appears to be little reported evidence for sewage flooding as a direct result of
inadequate sewer hydraulic capacity, though part of the sewage may be flowing in the
storm water drainage system. No work on sewers shall be permitted during monsoon
season. Similarly no excavation shall be permitted during notified period. The
intrusion of the storm water flow in the sewage system is to increase the hydraulic load
on both the conveyance and pumping systems and due to its effect on the sewer
infiltration / exfiltration, may result in possible disturbance of the ground in areas with
fine granular or poor soil conditions.

- 199 -
1.3.5 Ground Water

A systematic hydro-geological survey of Greater Mumbai areas was carried out by

Central Ground Water Board (CGWB) in 1989-90, based on the measurement of the
water levels in open wells in Greater Mumbai and the adjacent hinterland areas.
During both pre and post monsoon periods it was observed that the water levels were
between 0 and 2m depth in coastal areas (low lying tracts) 2 and 4 m or more in the
central elevated part of Salsette, Trombay and Southern tip of Bombay island. In most
of Greater Mumbai, the seasonal fluctuation was less than 2 m and 1989 it worked out
to only 0.76 m. Seasonal fluctuation of ground water table in the central elevated part
varied between 0 to 6.59 m. The data pertaining to the groundwater table confirms
that the majority of the sewer lines and almost all the normally deep sewers remain
below the groundwater table throughout the year.

The ground water during monsoon period is expected to be high and some time it is up
to the ground level. For the purpose of designing liners, the Contractor shall consider
that the ground water level is up to the ground level.

1.4 Mumbai Sewerage System

1.4.1 MCGM Sewers

MCGM is responsible for providing sewerage facilities for the city and suburbs,
covering an area of about 438 sq.km. There are seven sewerage catchment areas,
namely Colaba, Worli, Bandra, Versova, Malad, Bhandup and Ghatkopar and 52
major pumping stations in the Brihan Mumbai.

Presently the urban area of Mumbai is being served by a gravity collection sewerage
system involving a network of branch sewers, intercepting sewers and trunk sewers
having total length of about 1830 km.

Sewerage network comprising of sewer lines and manholes is now available on a GIS
system which uses ESRI, ArcView / Info format. The GIS information is available for
inspection in the SUMC at Dadar. Any bidder desirous of inspecting the same may do
so at his own cost.

- 200 -
1.4.2 Manholes

The manholes constructed on the sewerage system in Mumbai are usually conical
tapering manholes and trapezoidal and square scraper manholes. The conical
manhole is provided with the clear opening of 560 mm at the top while the opening for
trapezoidal manholes is 0.6 m x 0.9 m and that for scraper type is 1.2 m x 0.9 m. The
bottoms of the conical manholes are 1.2, 1.5 m, 1.8 m. diameter. The bottoms of the
scraper manholes on sewers under reference are 1.5m or 1.8m square. For easy
access to the sewer body, the manholes are generally provided at a distance of 30 m.

For structural lining method, the bidder has to design the structural liner system in
such a way that their installation can be carried out using the opening of manholes
only. Trenching shall be permitted only for making insertion trenches/pits/shafts and
for diversion of sewage flow. If, any other excavation becomes inevitable due to any
issue, the same shall be at risk and cost of the Contractor. Provisions for making
trenches and reinstatement of the same has been made in the bills of quantities.
Where the pits are dug by breaking the existing manholes, the contractor shall
reinstate the broken manhole.

1.5 Contractor’s responsibility of ascertaining extent of work

The Contractor is deemed to have visited the sites and familiarised himself of the

Contractor of any of his obligations under the Contract.

Unless noted otherwise, all calculations shall assume a minimum factor of safety
of 2 and a minimum factor of safety of 2.5 shall be assumed for buckling. The
Contractor shall, in addition, include design check calculations based on
structural design procedure included in the specifications.

(b) Design Responsibility

The Contractor shall be solely and wholly responsible for the suitability and
correctness of design calculations necessary to substantiate that the structural
lining system will be suitable in the long term for loads and conditions
experienced by the lining.

The design requirements set down in this specification shall be considered as

minimum requirements. The Contractor may adopt more conservative
assumptions or design methods should they consider it necessary to accept full
design responsibility.

Review of the Contractor's design calculations shall not be construed as

acceptance of the calculations. Responsibility of the design shall remain with the
Contractor.

The design of liner shall be carried out and approved by professional recognized
organization / institution like WRc, I.I.T. having particular experience in liner
design and structural assessment of sewers of similar nature and complexity to

under live sewer conditions. The Contractor must produce documentary

- 240 -
 evidence to substantiate that the system he offered shall have minimum thirty
(30) years of service life.

(d) Material Properties for Design

Where material properties under load vary with time, material properties of the
lining at the end of the service life specified shall be used in design calculations.
The exception to this is design of the lining for loads applied only during
installation, which may be based on short term material properties.

The material properties used in the design shall be consistent with the
composition of the lining material. Values for material properties may be
nominated by the Contractor but must be capable of being substantiated by test
data based on representative samples of the installed lining material. The
Contractor shall make provision in the Contract for such tests to be conducted

The stiffness consistency of the as-installed liners shall be checked on site to

ensure uniformity along the length of the rehabilitated sewer. Contractor shall
make provision in his prices to determine the actual thickness of the liner and the
engineering properties of the liner materials at manufacturer’s works or at
approved testing laboratory. The procedure for cutting and testing the liners and
the test laboratory shall be proposed by the Contractor for Engineer’s approval.

- 241 -
 Such test shall be carried out for each sewer size as per IS or any other relevant
international standard.

(g) Bending Radius

Congress AA Class Loading standard. Loads shall vary depending on the road
usage as follows:

TYPE A Main Road Multiple adjacent lanes of Standard T44 or Standard W7

wheel loads.

TYPE B Light Road Single lane of Standard T44 or Standard W7 wheel loads.

TYPE C Field Load 60 per cent of light road loading.

Design depths from surface level to invert level, and the type of traffic load used
for design of the lining, are given in this specification.

Traffic live and soils loads given in WRc SRM (2001) 4th Edition or AASTHO
HS20 loadings are acceptable.

Notwithstanding the designs submitted along with the bid, the successful bidder
(the Contractor) shall validate the designs as per the actual parametric values
related to soil properties based on investigations.

Following values shall be used for design purpose of the liners-

Minimum Ovality of the existing pipe shall be taken as 2%.

Soil Unit Weight shall be considered as 20 KN/m3.

- 243 -
(k) Installation Design Checks

Linings shall be checked to ensure that they are stable and will not be
overstressed for any intermediate states during the installation of the particular
system. These checks may be based on short term properties of the lining
material.

(l) Definition of Pipe Condition

For the purpose of this specification and for design purposes, the condition of the
existing sewer body shall be considered as Fully Deteriorated.

Fully Deteriorated: The sewer body has lost a sufficient degree of its original
structural capacity that it cannot be relied upon to support applied loads for the
next 50 years. The structural lining is expected to act as a structural replacement
for the original sewer to bear the full load from the ground, traffic and ground
water.

(m) Design Calculations

Hydraulic:

The design shall be based on the buckling strength of the lining with account
taken of the enhancement provided against a buckling mode of failure by the
existing pipe.

Design thickness shall be sufficient to withstand the hydrostatic pressure due to

groundwater without collapsing.

Structural Standalone:

The lining shall ignore any contribution from the original conduit and be designed
to support all imposed loads in its own right.

The lining shall be designed to satisfy the critical performance criteria of vertical
deflection, strength, and buckling under maximum combined loads

- 244 -
 Check for Flexural Strain-

The long term flexural strain developed in the wall of the lining for any load or load
combination shall not exceed the permissible value appropriate for the lining
material.

Check for Buckling Resistance

The lining shall be designed so that its buckling resistance is sufficient to support
the imposed loads .

Calculations shall also be provided to demonstrate that the existing structure will
not be overstressed by any combination of applied loading or reactions from the
installation or performance of the lining.

(n) Liner Thickness

The minimum structural liner thickness to satisfy combined hydrostatic, soil and
traffic loading shall be arrived at through the process of design calculations and
design checks to be carried out and approved by professions organizations /
institutions as mentioned in the specifications. The bidder shall supply design
calculations for each stretch of sewer line along with the bid. A detailed design
check will be conducted by the Engineer during the execution of work. The
Contractor shall note that the acceptance of his bid and award of the Contract by
the Employer will not in any way be considered as acceptance of the thicknesses
proposed in the bid. The Contractor shall clearly understand that if the structural
design thicknesses found to be inadequate during the detailed checking of
design, he shall be held solely and fully responsible to rectify and adjust the
thickness without any variation to the Contract price and to the compliance
requirements of the contract conditions. In case, the contractor fails to comply
with this requirement, the Engineer reserves the right to reject the proposal
altogether at the risk and cost of the contractor and without incurring any liability
on the part of the Employer.

- 245 -
(o) Surface Roughness Value

The improved surface roughness associated with the polymeric and plastic
materials of the liners has a considerable impact on the hydraulic capacity of the
renovated sewer when it is new. However with ageing of the renovated sewer,
the roughness values tend to be higher due to slime formation and accumulation
of silt at the invert. From the point of view of slime formation and localized
accumulation of silt in the renovated sewer, the roughness value to be adopted
for the purpose of this specification is limited to Manning Coefficient = 0.009 or
Colebrook White Roughness (Ks) = 1.5 mm for computing the hydraulic flow
capacity of sewers lined with all types of polymeric and plastic materials.

(p) Permitted Maximum Reduction in Cross Section

The structural liners must retain the largest possible internal diameters/
dimensions. The reduction in the physical cross sectional area of the existing
sewer lines after the rehabilitation shall be allowed up to a maximum of fifteen
percent (15%) of the actual cross-sectional area of the sewer. The above
requirement is mandatory and any offer exceeding the maximum permitted
reduction in cross sectional area will be summarily rejected.

The reduction in cross sectional area of existing sewer lines after rehabilitation
shall be exclusively in terms of physical dimensions. The Contractor shall support
the quoted percentage reduction in cross sectional area by submitting detailed
calculations with the bid (Technical Schedule). The improvement in hydraulic
capacity shall not be taken into account for calculating cross sectional area
reduction.

If the percentage of cross sectional area reduction exceeds offered value during
execution, the work will be rejected outright.

Any such rejected work shall be rectified by the contractor at his own cost and
shall bring the reduction in the cross sectional area within offered value.

At tender stage, nominal diameter of the sewer shall be used for calculating
percentage area reduction. At the execution stage, actual internal diameter of

- 246 -
 the sewer line measured using laser equipment and by passing custom made
template to account for undulations due to displaced joints, ovality, etc. shall be
used as best fit internal diameter for calculation of percentage area reduction

(q) Method Involving Internal Loading

The structural capacity of the existing sewer is unknown. Any method involving
internal loading on to the sewer body during the construction operation will be
viewed cautiously.

(r) Method involving Reaming or Grinding

If reaming or grinding or mechanical scrapping of the internal surface of the

sewer body is proposed by the Contractor to upsize, or minimise the loss of cross
sectional area, or regularise (and standardise) the shape and size of the sewer
during the construction operation, the Contractor shall carryout a structural
assessment of the existing sewer and necessary temporary structural
enhancement to the sewer body, such as grouting the voids, if present behind the
sewer body, filling up of any missing mortar and make the sewer body
temporarily fit to sustain such temporary loadings arising from the proposed
construction process. The contractor shall submit the details of the structural
enhancement measures he proposes to carryout for the Engineer’s approval and
submit calculations and test result to prove that the proposed construction
process involving grinding or reaming operation is safe and the integrity of the
existing sewer body is intact. All the cost associated with structural assessment,
certification by the rehabilitation engineer and safety of the sewer shall be borne
by the Contractor.

6 Part 6 – Guidelines for Safe Entry and Working inside Sewers

6.1 Introduction

These general guidelines are intended to assist the Contractor in the development of
safe work practices. Where the risk assessment indicates that a particular hazard
cannot be present, the precautions to control that hazard do not apply. Remember
that a favourable history does not guarantee absence of hazard on this occasion.

6.2 Confined Space

“Confined space”, in relation to a place of work, means a space of any volume which a
person may at any time enter or be allowed to be enter in which the atmosphere is
liable at any time to be oxygen deficient. This includes but not limited to pipes, sewers,
manholes, tunnels, shafts, ducts, other similar sewerage installations and etc.

The Contractor shall develop acceptable work practices and safe entry procedures
based on the guidelines provided hereunder and the Corporations’ guidelines on
safety precautions to be observed during sewer desilting work included in this
specification and implemented on site.

6.3 Notification to Work in Confined Space

The Contractor shall obtain an entry permit from the Engineer for each occupancy of
any confined space. The Contractor shall furnish all required details in an approved
format to the Engineer for permission to work in confined space at least 24 hours prior
to the entry. Where prolonged work is involved, the permit must be renewed for each
shift. An incident which substantially alters the condition of a confined space entry
requires immediate evacuation and reassessment of the condition. Copies of all entry
permits relating to previous shift must be submitted to the Engineer immediately upon
exit of the persons working in those shifts and in any case before further entry permits
are sought. No new entry permits shall be issued unless proper record of exit by
workmen from earlier shift is submitted to the Engineer’s representative.

- 265 -
6.4 Air Quality and Ventilation

Contaminant control and effective ventilation are major factors influencing air quality in
a confined space while working in sewers/manhole. The ventilation must be adequate
to clear pre-existing contaminated air and maintain a respirable atmosphere during
planned work. This ventilation may be permanently installed or portable equipment
used for this task. For general ventilation, fresh air shall be supplied to the workplace.
Within the sewer system this creates an environment which displaces contaminated
air in the immediate vicinity.

Where a task generates atmospheric contaminants in a specific area, adequate local

exhaust ventilation should be used to remove the contaminants. Where failure of the
mechanical ventilation system would result in deterioration of air quality, the controls
must be clearly tagged to prevent accidental interference and the ventilation system
monitored while the confined space sewer/manhole is occupied. Self Rescuers must
be carried whenever failure of the ventilation system or changes in the working
environment can create a contaminated atmosphere. The self rescuer can be a self
contained breathing apparatus, oxygen self rescuer, or short duration self contained
breathing apparatus, depending on the time taken to reach open air.

Note: Obtain occupational hygiene advice on the- selection or performance of

ventilation system where this is not specified in the work practice.

6.5 Lighting

Any regularly accessed confined space sewer/manhole should be illuminated with

electrical installation to appropriate Indian Standard or equivalent. Portable lighting
may be used to supplement permanent lighting in the workplace. Temporary mains
powered lighting installed for a task must comply with the requirements of appropriate
Indian Standard. Miners lamps, mounted on a safety helmet may be used as an
alternative to a hand held torch for personal illumination.

The possibility of a flammable atmosphere must be eliminated by isolation, cleaning,

ventilation purging etc.

- 266 -
Where the confined space has been proclaimed as a flammable gas hazard area, all
fixed and temporary electrical installation must comply with appropriate Indian
standard. Torches and portable lights must comply with appropriate Indian standard.

Illumination standards are:-

 General Lighting:- 40 lux minimum, equivalent to a poorly lit room

 Stairway lighting:- 80 lux minimum

 Task Lighting: - 240 lux minimum (normal workshop requirements)

6.6 Equipment usage, Standards and Maintenance

All confined space safety equipment must meet established standards and be of
appropriate design for the proposed usage. The equipment must be checked for
visible damage and correct operation before each use. Preventative maintenance
must be performed by trained, and where necessary, authorised persons at the
intervals recommended by the equipment manufacturers. The Contractor shall submit
to the Engineer evidence of such periodic check, Calibration and maintenance of the
equipment used for confined space entry at every month during the first week of the
month.

6.7 Room to Work

When the constricted volume of a worksite prevents normal work postures and tool
movement, the need for special tools or frequent work rotation should be considered.

6.8 Control of Flooding

When a confined space is normally liquid filled, accidental return to service must be
prevented by double isolation e.g. insertion of suitable blanking piece, plugging with
inflatable plugs, temporary coffer dams as a second isolation in a manhole or other
effective means.

6.9 Flow Control

Where a sewer is entered while flowing, rapid increase in flow must be prevented by
use of stop logs. Isolation of pumping stations, weather watch and other means

- 267 -
appropriate to the sewer catchment. Adequate communication with the person
responsible for flow diversion must be maintained for the duration of the entry.

6.10 Drowning

Where deep or flowing water is present, use of personal flotation devices. Safety
harness and lifeline, safety nets etc. as appropriate to prevent drowning.

6.11 Fire and Explosion

Adequate precautions must be taken to minimise the risk of fire or explosion when
entering a confined space for any purpose during all activities of sewer desilting,
CCTV inspection and condition assessment in particular during desilting of sewer and
while working in manhole/sewer

6.12 Presence of Flammable Gas

The presence of flammable gas, flammable dust or the possibility of the presence of
airborne substances in flammable quantities may create a hazardous Area. Care shall
be taken by the authorised person to determine the presence of any such flammable
situation in the confined space before entry. Smoking or lighting any cigarette or box
matches in confined space shall be strictly prohibited. The flammable gases of
concern are methane, digester gas, vapours from flammable liquid, and vapours and
gases from trade waste discharges.

6.13 Manual Handling of Tools etc

Safe system of work should be followed to protect against fall of persons or objects
and crush by moving or falling objects. Extra care is needed if normal manual handling
gear is not available or confined space safety gear (Harness, Respirator) is worn.

6.14 Noise

Reverberation within a confined space can increase noise levels, especially if more
than one person is working. Heavy duty hearing protection may be required. The
Contractor must comply with the requirement of noise levels under Environmental
Protection Act and Rules.

- 268 -
6.15 Vermin

All persons working in confined spaces should be aware of the health hazards
presented by the presence of vermin. The presence of cockroaches etc does NOT
indicate that the atmosphere is free of danger to health.

6.16 Standby and Communication

A member of the confined space work team is allocated the task of maintaining
communication with the members inside the confined spaces. This task may be
rotated among the members of the team. The Standby person must be trained and be
physically capable of providing the assistance and life support in an emergency and
must have sufficient proficiency in Marathi, Hindi and English languages to promptly
communicate information by radio or telephone when required.

While acting as stand-by, this person must not enter the confined space or leave the
vicinity unless relieved from this duty. A standby person is needed for all confined
space entries. The Safe System of Work must indicate the process for communication
from the confined space to the standby, e.g. 2 way radios. 'Man down' alarm, line of
sight etc.

6.17 Fitness Assessment

A periodic assessment of fitness, including cardiovascular and respiratory health, is

required to ensure that all persons entering confined spaces, or acting as the stand-by
person, can comply with the physical demands of the job, without risk to their health

6.18 Emergency Rescue and First Aid

No person shall enter any confined space, even in an emergency, without first
ensuring all safety requirements have been met. A safety emergency plan may assist
in a safe, speedy response in the event of an emergency.

All confined space work teams must be trained and equipped to sustain life and be
able to summon emergency help. Provide first aid and assist emergency service
personnel, if requested.

- 269 -
Rescue of persons apparently overcome by toxic gases in a sewer/manhole or other
confined space must only be attempted by trained persons using supplied air
breathing apparatus. Stabilisation of other injuries must be prioritised against the
availability of breathable air.

6.19 Gas Detector

The Contractor shall engage an authorised person for gas monitoring and detection.
This person shall be trained to operate and response test gas testing equipment and is
authorised by management to perform the necessary tests to decide whether a
confined space is fit to enter.

Gas testing can only be performed by persons trained in gas testing, using equipment
appropriate for the anticipated contaminants. This person can perform other duties
provided these do not conflict with the gas testing task

6.20 Specialist Gas Detector

This person has technical qualifications and acceptable training to operate and
response test gas testing equipment, including hydrocarbon detectors and detector
tubes and assesses portable ventilation systems. He is authorised by management to
carry out atmospheric testing to establish entry conditions for all confined space
categories. He also performs tests to verify whether hot work is permitted in gas
hazard areas. He shall ensure that the Gas Detector unit has been properly calibrated
and fit to be used in the given circumstances.

6.21 Cleaning

Where possible, cleaning should be performed without entry to the confined space.

Particular attention should be given to the probability of releasing hydrogen sulphide

when disturbing microbial active sludge and sediments which have accumulated in a
confined space. Supplied air respiratory protection shall be worn where such residues
exist and effective ventilation cannot be guaranteed. Continuous gas monitoring is
required even when supplied air respirator protection is used.

- 270 -
Hose couplings should be designed to resist accidental dislodging or loosening. Both
the operators and the standby person should be able to stop the flow of cleaning
material into the confined space.

Hydro jetting must be performed according to the relevant regulations. Where

chemical compound is used in within the confined space, the chemical compound
should be classed in the Material Safety Data Sheets as non-irritant to respiratory
system, eyes and skin. If this is not possible then appropriate respirator skin and eye
protection must be worn. Substance specific air monitoring may be required.

6.22 Visitors

A visitor to a confined space is a person other than a contractor, who is not a member
of the Confined Space Work team. Visitors must be escorted and trained or inducted
in the necessary skills for that entry and shall sign an indemnity form before entry into
a confined space.

6.23 Hazard Control

Hazards to be identified and controlled include but are not limited to: access.
Mechanical and electrical isolation, flow isolation and control, drowning and
engulfment, last known contents, atmospheric contaminants, temperature extremes,
security and public access.

6.24 Definition

Parts Per Million (ppm)

Parts of gas or vapour per million parts of contaminated air by volume at 20oC and 1
bar pressure.

1 ppm = 0.0001%

Percentage

Parts of substance per 100 parts of air, water etc.

1 % = 10,000 ppm

- 271 -
6.25 Air Quality Standard for Entry

The acceptable limits of some gases in confined spaces are:

Gas/Vapour Present Acceptable Limits

Oxygen Content (O2) 19.5% to 23.5% by volume

Flammable Gas/Vapour 5% of Lower Explosive Level (LEL)

Hydrogen Sulphide (H2S) 10 Parts Per Million (ppm) Maximum (For Visitors)
Reducing to 5 ppm for members of the public

Carbon Monoxide (CO) 30 Parts Per Million (ppm) Maximum Carbon Monoxide
(CO) (For Visitors) Reducing to 10 ppm for members
of the public.

6.26 Carbon Monoxide (CO)

Carbon monoxide is colorless. Odorless, flammable and toxic. Its common sources
are fire, motor vehicle exhausts and cigarette smoke.

This gas is a chemical asphyxiant and is readily absorbed by the hemoglobin in the
blood. Then hemoglobin is unable to transport oxygen to the body tissues and the
body becomes oxygen starved. These effects are more pronounced with hard work or
for heavy smokers. Symptoms include headache (50-200ppm), nausea (400ppm),
and irregular heartbeat (1200ppm). Collapse and death (2000ppm).

The entry permit limit is 30 Parts per Million (ppm). Maximum with an IDLH value of
1500 ppm. The entry limit reduces to 10 ppm for members of the public. (IDLH-
Immediately Dangerous to Life and Health)

Note: Some gas detecting machine sensors are cross sensitive, H2S being detected
by the CO cell and vice versa. Alarm by either sensor requires evacuation and
re-evaluation of the safe system of work.

6.27 Flammable Gas/ Vapour

A gas or vapour which will burn when mixed with air in certain proportions and ignited.

- 272 -
The mixture which contains the least amount of flammable gases which will explode is
called the Lower Explosive Limit (LEL) The mixture, which contains just enough
Oxygen to let the flammable gas explode. Is called the Upper Explosive Limit (UEL).
The flammable range varies for gases and vapours.

Many of these have toxic effects when inhaled and a Workplace Exposure Standard
has been issued to protect workers from this Gas/Vapour. The Contractor shall obtain
relevant Workplace Exposure Standard (WES) for use in the site.

Flammable
Gas/ Vapour 5% LEL WES
Range in %
Butane
1.9- 8.5 950ppm 800ppm

n-Hexane 1.2 -6.9 600ppm 50ppm

Methane 5-15 2500ppm Axphyxiant

Petrol 1.3 - 6 650ppm 900mg/cum

Trichloroethylene 12.5 - 90 6259ppm 50ppm

6.28 Hydrogen Sulphide (H2S)

Hydrogen sulphide is a colourless, toxic and flammable gas which usually has the
odour of rotten eggs. ln sewerage systems it is usually derived from the action of
bacteria on the sulphur compounds in anaerobic or old sewage. A small amount of
sludge or slime in wet wells or sewers will release a lot of H2S when disturbed.

After a few minutes exposure, the ability to smell hydrogen sulphide by a person is lost
and then hydrogen sulphide becomes more dangerous as its presence is no longer
obvious and the person could become an innocent victim.

It can sometimes be detected by odour at less than 0.1 ppm but can be readily
detected by odour at 4ppm. More serious health effects include eye irritation (10ppm),
respiratory irritation (50 ppm), headache, nausea, dizziness (20oppm), collapse and
death (300ppm).

- 273 -
The entry permit limit is 10 Parts per Million (ppm), Maximum with an IDLH value of
300ppm. The entry permit reduces to 5 ppm for members of the public.

Note: Some gas detecting machine sensors are cross sensitive, H2S being detected
by the CO cell and vice versa. Alarm by either sensor requires evacuation and
re-evaluation of the safe system of work.

6.29 Methane (CH4)

The most common flammable gas found in sewers is methane. This mainly comes
from gas pipe leaks in the city’s gas distribution systems. It can also be derived from
the action of anaerobic bacteria on rotting material. However a range of other
flammable gases and vapours may be encountered. These include LPG, petrol
vapour and other solvents.

Digester gas, found in anaerobic sludge digesters on sewage treatment plants is a

flammable mixture of methane nitrogen and carbon dioxide.

Methane is a colourless, odourless gas. Although pure methane is slightly lighter than
air. The relative density of methane/ air mixtures is similar to air in the entry permit
range. Methane is hazardous because of its flammability, i.e. between concentrations
of 5% to 15% in air, may explode if an ignition source is present.

High concentrations of methane may result in oxygen deficiency. Injury or death

results from lack of oxygen not methane toxicity classifying methane as a simple
asphyxiant.

Note: that the entry permits level is 5% of LEL, NOT 5% flammable gas.

6.30 Oxygen Content (O2)

Fresh air contains about 20.9% oxygen.

In a confined space, oxygen can be used up by bacteria in sewage or sludge, rusting

of iron fittings, burning (or welding) or displaced (pushed out) by other gases.

- 274 -
Breathing of air which contains reduced oxygen results in increasingly serious health
effects. These range from impaired coordination and faulty judgement (12-16% O2) to
collapse and rapid death (less 6% O2)

Increased oxygen readings can only come from instrument error or by leakage from
oxygen cylinders, liquid oxygen tank, etc. High oxygen levels greatly increase fire
hazards, fires burn fiercely; oily clothing and hair can catch fire without an ignition
source.

The entry permit levels are 19.5% to 23.5 % by volume.

6.31 Other Atmospheric Contaminants

Entry, unless wearing air supplied breathing apparatus, is not permitted unless
atmosphere contaminants are below the relevant 8 hour time weighted average (TWA)
Workplace Exposure Standard. This limit applies for all entries including brief
exposures. Entry wearing breathing apparatus is only permitted where the
concentration of the contaminant is within the protection factor of the breathing
apparatus and below the IDLH (Immediately Dangerous to Life & Health) value.

6.32 Sewer Gases

Air in contact with live sewage contains gases released from the sewer. For safe
entry, contaminated air must be replaced with clean air by ventilation of the confined
space. The resulting atmosphere must be confirmed by gas testing.

Discharge of untreated wastes, e.g. hypo chlorites, electroplating effluent, acids may
result in generation of chlorine, hydrogen cyanide and other harmful gases some
distance from the original discharge.

6.33 Confined Space Categorisation

The confined space category is a guide to developing a safe system of work. The
confined space category may change to a more stringent level as a result of adverse
environmental factors or work produced contaminants. Alternatively it may change to a
less restrictive category if appropriate engineering upgrades, whether temporary or
permanent, are implemented.

- 275 -
Category 1 - Confined Space

Entry allowed only if flammable gas is below 5% of L.E.L. and other gases are within
the protection factor of the respiratory protective equipment used.

Visibility must be adequate

Personal Safety

 Wear specified protective clothing for the hazards

 Wear safety harness

 Use lifeline where appropriate

Respiratory Protection

 Test air quality prior to entry by a Specialist Gas Detector

 Ventilate to reduce contamination

 Monitor air quality as directed by the Specialist Gas Detector

 wear airline breathing apparatus with backup air supply OR wear self contained
breathing apparatus

Note: Oxygen self rescuer is not a backup for an airline used in contaminated
atmospheres.

If the Category 1 confined space is a chemical storage tank, it can be reclassified to a

Category 2 or 3 confined space when the Specialist Gas Detector confirms that the
chemical has been cleared from the interior.

Sewer, wet wells etc can be reclassified by a Specialist Gas Detector to a lesser
confined space only when an approved safe system of work is employed. This safe
system of work must provide for demonstrated control of airborne contaminants and
other hazards in the workplace, to provide conditions equivalent to a category 2

- 276 -
Hot work requires control of fire and explosion hazards and may require air supplied
breathing apparatus to control fumes irrespective of the confined space category. A
Hot work permit is required in addition to the normal entry permit.

Category 2 - Confined Space

Entry allowed only if all gases are within entry permit limits

Personal Safety

 Wear specified protective clothing for the hazards

 Wear safety harness

 Use lifeline where appropriate

Respiratory Protection

 Test air quality prior to entry

 If air quality test fails refuse entry until reason found and rectified, or revert to
Category 1 entry conditions.

 Ensure adequate ventilation

 Monitor air quality during entry

 Carry oxygen self rescuer

Note: Standby person must have SCBA readily available.

Hot work requires control of fire and explosion. Hazards and may require air supplied
breathing apparatus to control fumes irrespective of the confined space category. A
Hot work permit is required in addition to the normal entry permit. A hydrocarbon
check by a 'specialist gas detector' is required unless the environment can be
upgraded to Category 3 conditions.

- 277 -
Category 3 - Confined Space

Entry permit required (unless using a posted entry procedure for routine operation of
the facility) for each shift that the structure be occupied.

Personal Safety

 wear protective clothing specified for the hazards

Respiratory Protection

 test air quality prior to entry

 If the proposed work can generate airborne contaminants, arrange ventilation.

Respiratory protection and/or air quality monitoring as appropriate.

 Hot work requires hot work permit and control of fumes.

 If air quality test fails, revert to Category 1 entry conditions or refuse entry until
reasons found and rectified.

Category 4 - Confined Space

Follow facility safety procedures.

Personal Safety

 Wear protective clothing specified for the hazards

Respiratory Protection

 Evacuate when alarms advise

 Hot work requires control of fumes.

Separate Permit(s) required for chemical cleaning and/ or Hot Work. If evacuation
alarm sounds, evacuate following site emergency procedure. Reoccupy as a Category
2 confined space.

6.39 Safety Procedures and Precautions

(To be taken during desilting, CCTV inspection and condition assessment works as
well as installation and testing procedures as per standing guidelines of MCGM)

(1) Before opening any manholes, the stretch shall be properly barricaded and
isolated in accordance with the safety requirements and the permission issued by
the traffic police. The workmen on ground shall be provided with reflective safety
jackets and a person shall be positioned to guide the traffic in vicinity of the work
site to prevent any traffic accident involving the workmen or third party. To begin
with the work of desilting, initially six consecutive manholes are to be opened, two
on the upstream and two on the downstream side of the two manholes, on the
actual stretch to be cleaned or desilted. The manholes should be kept open for
one hour prior to the starting of cleansing operations and should be so kept open
during the whole duration of cleaning operations. This to be done for allowing the
combustible gases to escape naturally. No lighted match sticks should be thrown
in the manhole. This may cause fire and explosions endangering the life of the

- 281 -
 workmen and the pedestrians. This may also damage to the sewer and other
adjoining utility services, if any.

(2) Jalis (safety screens) should be placed over all the opened manholes to prevent
pedestrians etc., from falling in. Tripod stands with flags painted red should be
placed over the manholes. The letters “Danger - Manhole Open” should be
written in white reflective paint on the red background.

(3) When working at night, lantern fitted with red globe and lights shall be placed with
a temporary cover over the manhole, so that top of the cover is flush with the road
surface. The covers shall be provided by the contractor without any extra cost.
The same should be removed and replaced with regular manhole cover when the
work is closed after ensuring that every worker entering the manhole/sewer has
come out of the same.

(4) The Contractor should keep sufficient number measurement rods.The

measurement rods shall be made out of solid bamboo / M.S. rod of sufficient
length fixed with M.S. flat 150 mm x 150 mm x 6 mm (6” x 6” and ¼”) thick at one
end and fitted with point at other end, to take measurement of water and silt.

(5) Manholes shall be kept open for minimum one hour to allow foul gases to escape
and simultaneously there should be forced purging with the help of an air blower
to completely clean the air in the sewer.

(6) Sewage levels shall be checked in the manholes and the same should not be
more than 100mm (4”) or 10% of height whichever is lower.

(7) Wet lead acetate paper shall be inserted in the manholes which should not turn
even light brown or black. If the lead acetate paper turns light brown or black,
then the atmosphere inside manhole indicate the presence of Hydrogen Sulphide
Gas (H2S) and in that case this test shall be repeated after every ten minutes till
positive result is achieved. The sensitivity of lead acetate papers should be
ascertained to suit and detect the minimum allowable concentration (MAC) for
long term exposure. This paper should be held as low as possible in the manhole
atmosphere.

- 282 -
(8) In spite of long waiting for about one and half hour, if the lead acetate paper
continues to show negative result, air blower shall be used for half an hour.
Thereafter gas detector shall be used to check the presence of gases and the
worker shall be allowed only after it is confirmed by the Safety Officer/engineer in
writing by issuing an Entry Permit that the condition insider the manhole is safe
for man entry. Wherever necessary, or where the sewer line is heavily silted or
there are chances of gas eruption, the person entering the manhole shall be
provided with gas mask or breathing apparatus and hand blower or mechanical
blower for use. Notwithstanding the lead acetate paper test or any other
conventional tests use of gas monitor in working condition in every case is
mandatory. The gas monitors should be accurately calibrated after regular
intervals to maintain their reliability

(9) After the lead acetate paper test, a lighted Davy’s safety lamp shall be inserted in
the manhole which should burn smoothly. If not, it shows the presence of Carbon
monoxide (CO) and in that case precautionary measures as stated should be
followed.

(10) After the presence of combustible gases is ruled out, further test is required to be
carried out for the presence of oxygen.

(11) lighted naked candle placed at the centre of the candle testing equipment
covered with glass on three sides should be lowered down slowly. If the flame is
extinguished or flickers, it indicates the presence of carbon – monoxide and or
carbon dioxide. If it burns for not less than five minutes uniformly, it indicates the
presence of oxygen which is required for breathing for the workman working
inside the manhole.

(12) Working inside the Manhole

After all these tests are carried out successfully, particular care should be taken
where sewer is heavily silted that scum and sullage thoroughly stirred and
disturbed by means of long bamboos / G.I. Rod from the top of the manhole to
allow entrapped gases within silt pockets to escape before allowing the labourers
to enter into the manhole.

- 283 -
The depth of water should be measured and the labourer should be allowed to
enter the manhole only when the level of water is less than 100 mm (4”).

Before the labourer is allowed to get down inside the manhole, he should be
asked to apply barrier creams all over the body as a precautionary measure to
safeguard against itching and burning sensation. Safety belt/ harness with sturdy
rope should be tied around his waist and chest when the labourers getting down,
another man at the top should hold the other end of the rope which is tied to the
harness of the labourers getting down / going down the manhole.

Not less than two people should be allowed to work inside the manhole at a time.
Working alone in manhole/confined space shall not be permitted under any
circumstances. They should always be sent in pairs. The labourers should not be
asked to work for more than one hour at a time inside the manhole. If the work
has to go on continuously, another pair of labourer should be asked to get down
after the one hour period of the earlier pair.

If the labourers who are working inside the manhole show even light discomfort,
they should be asked to come up or pulled up. The labourers who are working
inside the manhole should given jerks very few minutes to signify that everything
is okay with them. A safely secured winch pulley system shall be provided for the
worker to get down the manhole or for pulling out the workers.

After getting satisfactory test result and after taking precautionary measures as
stated above and issue of safety permit and certification by the Safety
Officer/engineer, the worker shall be allowed to descend or enter in the manhole
using winch pully system/ aluminium ladder of adequate strength and approved
type providing access to the bottom of the manhole. The worker shall wear
personal protective gear before working inside the manhole. The workers
entering the manhole shall be provided with wadder suit, hand gloves protective
head gears, gumboots, abrasion resistant gloves, safety goggle, head lamp etc.

It should be remembered that in spite of the manhole entry tests being carried
out, there are chances of eruption of poisonous gases in the silt and the safety
officer/engineer shall properly brief the workman working in confined spaces on
such issues and ways to overcome any emergency situations. If the worker finds

- 284 -
 any difficulty in breathing initially or during the work then he should be taken out
immediately by means of harness belt. Where the sewer line is heavily silted or
there are chances of gas eruption, gas mask must be used while entering the
manhole and also during desilting.

If the worker inside the manhole requires any instrument, the same should be tied
to rope and lowered slowly inside the manhole ensuring the safety of the worker
working inside the manhole.

(13) On completion of the work, prior to closing of the manhole, the supervisor shall
make sure to count the number of workers to ensure that all of the workers who
went down the manhole have come out and no worker is left inside the
manhole/sewer. The name of all workers shall be tallied with those in the entry
permit form and shall be signed by the supervisor prior to submitting the same to
the Engineer.

(14) On completion of the work, all manholes shall be checked and it should be
ascertained that all tools or equipment are removed from the manholes the same
are properly closed

(15) The workers emerging out of work inside the manholes and sewer shall be
provided with bathing facilities for their hygiene. As necessary health check up
shall also be arranged for the workers.

6.40 Scheme for Safety Measures and Welfare of the Workers (Engaged by

Contractor shall obtain his own copy of the scheme and ensure that he complies
fully with the statutory requirements.A suitable penalty shall be imposed on the
Contractor for noncompliance of the conditions related to health, safety and
welfare of the workers and other conditions of the scheme. Under no
circumstances the contractors shall be allowed to start the work of cleaning and /
or desilting and/or repairs including CCTV inspection and Condition assessment
of the sewer lines / manholes, until the requisite insurance cover involving all
risks and the workmen and third party are obtained and kept alive by the
Contractor and accepted by the Engineer and verified by the Engineer and safety
measures are adopted on site. Senior Officers of MCGM will also verify during
their periodical inspections that proper safety procedures are followed and record
is maintained and the various conditions related to safety and welfare of the
workers is fully complied with. As necessary periodic mock drills shall also be
carried out for the work crew under the guidance of the project manager /safety
officer/engineer.
