Al Gurm Resort, UAE

The Al Gurm Resort in Abu Dhabi utilizes a 5.2 km vacuum sewer system with 69 valves to collect wastewater from land villas located among mangrove forests into a central vacuum station. The vacuum sewer pipes are suspended from the underside of roads connecting the villas. Wastewater enters the vacuum network through interface valves in chambers by each villa and is transported to a 10 cubic meter storage vessel at the vacuum station before being pumped almost 1 km to a gravity sewer. The vacuum system was chosen to preserve the ecological balance of the surrounding nature.

Al GURM RESORT,

ABU DHABI, UAE


Client: Abu Dhabi Sewerage Services Company (ADSSC)
Country: United Arab Emirates
Length of Pipe: 5.2 km
No. of Valves: 69 + 10 valve chamber extension in 2019
Volume of Flow: 15 litres/second
Specialist Feature: The vacuum sewer pipes are suspended by brackets
on the underside of the road network connecting the villas. Also, large
bridge crossing utilising a carefully designed ladder of lifts in the vacuum
sewer pipe.

The Al Gurm Resort is a residential and tourist development nestled among the mangrove forests of Abu
Dhabi. The area is home to many unique plant and bird species, making it one of the UAE’s top choices
for luxurious and tranquil living arrangements.

The project was realised in partnership with Iseki’s official Abu Dhabi distributor Metco and comprises a
vacuum collection system with a single vacuum station centrally located between the land villas.

Effluent is collected by gravity from individual villas to dedicated valve chambers sited in the vicinity of
the villas. The effluent enters the vacuum sewer network through a vacuum interface valve installed with-
in each valve chamber.

The sewer network is constantly under vacuum and as the interface valve opens, the differential pressure
forces the effluent into the sewer network which is suspended on the underside of the road network posi-
tioned on column within the mangrove forest.

The effluent is transported onwards to a vacuum vessel located at the vacuum station on the mainland.
The vessel acts as a vacuum receiver and storage facility for the effluent prior to discharge.
Vacuum Pipework
The polyethylene pipework used for the vacuum sewer net-
work around the resort ranges in size from 90mm to 160mm
diameter with use of electro-fusion fitting throughout.

Vacuum Station Equipment


3 No rotary vane vacuum pumps each rated at 500 cubic me-
tres/Hr (Busch) acting in duty/assist/assist configuration.

2 No dry well discharge pumps each rated at 15 l/s (Hidrostal)


duty/standby. The effluent is pumped through a 180mm diam-
eter rising main to a gravity sewer located approximately 950
meters to the East.

Vacuum collection vessel volume - 10 cubic metre fully pro-


tected with epoxy coating and tested to Lloyds certification

Motor Control Centre - fully automatic with programmable


PLC. All pumps start in rotation and all operating conditions are
monitored via station telemetry.

Bespoke valve monitoring system which monitors the open /


closed mode of each interface valve located around the site.

Vacuum pump exhaust gases are filtered by passing through a


biofiltration system located on the vacuum station roof. The
unit has a sun shade and irrigation system to ensure correct
operation.

Summary
Vacuum technology proved the ideal solution for this prestig-
ious resort due to the sensitivities of the surrounding areas and
the topography. The vacuum sewer pipes are housed in the
deck of a bridge crossing situated through the mangroves and
continues on to connect all the residential villas. This ensures
that the development preserves the ecological balance of the
surrounding nature.
