SewerGMS

1. Here we have ribbon tap that consist of most common used commands.

2. First it is important to adjust our units for project go to this arrow and open option, or using
Tools Tap

3. or you can easily use this search bar and type and
command you want.
4. after open option let’s customize

5. change your unit for here use Rest Defaults

6. or you can modify the units

7. in Labeling Tap you can adjust the Prefix for your system.
*Note: Conduit = Pipe
Outfall = Pump Station
Catch Area = area that where rain collected

8. you can scale your whole drawing or symbol or text only.

9. Prepare your model arch first
and save it in dxf file and name
it arch , then draw your pipe
and save in dxf and name it pipe
, then open SewerGMS and go
to view tap then background
and import arch file

*Note: it is preferred to draw your network

with command (Line) in AutoCAD while
using Sewer, but if you are using water
network use (Polyline).
10. In SewerGMS use Model Builder command

11. choose New to import your CAD file

12. import CAD File 13. After import if your files show that (polygon)

0 indicate for layer.

so that is Closed Shapes not pipe but if it show (polyline)

that means Pipe

14.adjust the object unit. 15.

16.after import click Zoom Extents 17. After import program automatically will put

manhole between pipes put it is small, so we use scale

command.
 18. go to view tap and
enable symbology and
use autohide.

symbology used to hide or

reveal object.

19. Using annotation to add more data to your drawing.

20. to add multi-annotation together use this

three dots.
21. When you double click on pipe it’s properties will
appear, and you can adjust. You can add ground level
for manhole

22. If you want to scale the pipe length, you can make (Has
User Define Length) =True then you can adjust the
length, unified means the actual length
23. to change solver, go to home tap then option double click Base calculation option you can find
different methods for solver

24. to multi-edit different manholes for example at same time

25. you can get your ground level for your

manhole from file or as .dxf points
26. after import your
level points
maybe you will
find some points
out of your
border so you can
easily adjust
these points from
Flex Tables

27. So, your problem now as

example is with manholes
levels, go to elevation and
sort it by ascending , 0 level
means that these points has
problem maybe it out of your
zone
 28. after you find the point with problem
you can right click on it and zoom to

it will display this point

29. you can use Edit to adjust your apparent column ,add or remove label that you want
30. you can export this table in 3 deferent format

31. or you can make special FlexTable with specific labels, for pipe as example

32. you can modify now from this table any change in this table it will affect the drawing
 33. now let’s go to Analysis Tap add Design Constraints to make
limits for your design
*Note: We have Global Constraints that are constraints for all
pipes
And we have Local Constraints that are specific for a certain pipe

This is Global Constraints

34. level of inner pipe diameter = pipe crown

level of outer pipe diameter = pipe soffit
let’s choose pipe soffit
cover (minimum), above the pipe = 1.2m
based on Sewer system Code
and Cover max = 6m

fast Note preferred unit for slope is m/km

35. at slope tap we are using Table
because of every diameter has minimum and max
slope
minimum = The slope that achieves self-cleaning
velocity

enable Part Full Design and put 75%

36. At Node tap

if we are working as drainage, we are using Crowns
to ensure that smallest pipe at high invert level
37. But if we are working as rain drain, we are using
Inverts

38. We are using (Allow Drop Structure) because

of your ground suddenly dropped so the
program automatic increasing this depth of
manhole to continue connecting other pipe
39. let’s add and modife the catalog 40. You can import from libarry

41. use PVC 42. Remove 100/150 cuz we are start from
200 mm

43. when you open the

manufacturing catalog, we are using pipe
with 6 bar for drainage , but in water
system we are using 10 or 16 bar
 44. you can easily modify the unit by right
click

45. it is important to modify the inner diameter and add thickness ( the input in the program is
the thickness times 2 )

It is not preferred to make these tables as templet because this will affect the result but you can
copy paste these values

45. you can choose part of your drawing and edit that part
46. go to flex table – conduit

And add conduit type and catalog class and size and material

to make the pipes using your catalog

 47. important option to check because of different solver will lead to different data on flex tables

48. to edit multi conduit go to any tap and global edit

49. this size not actual size it just Label

50. But this not correct Manning’s Number
and we can’t change it from Flextable so
let’s modify it by right click then Global Edit

51. preferred to enable notification to monitor the

status

52. let’s add or Loading or the flow so 53. Choose second one Unit type and Count

double click on the manhole and go to Sanitary Load that is common used

and click on 3 dots

 54. so we here describe number of people the all use this
manhole

To describe the load or flow or each so click on three dots

Choose population base because we add umber of people

Summary for how to add the Load

55. in short word after you draw your network to add the load to all manhole first use Unit Sanitary to
define how much the person will consume each day

second go to Sanitary Load Control Center and the Initialize Unit Loads for all elements

Third add the load to all of your manhole

Sure, you can modify all at same time by

right click on the column you want
 56. to make diverse or to not compute the max flow you are to add factors to the equation

Go to components tap and then Extreme Flows ‫ده لالستهالك السكان والمنازل لكن الخدمات للمبني مش‬
‫بضربها في معادله‬

57. you can easily choose the equation from the library

If your population under 80.000 choose (Babbitt Equation)

And if it more than 80.000 use (Hamon Equation) Modify the factor
58. now choose Extreme Flow setups, now add the eq to each system we
make note that this sum of all manhole with same unit load so we need to
be careful it is exceeded 80.000 or not

You simply chose a unit load, for example, let it be 160 l/s for a certain number of manholes, each of
which has a different number of people, so what will appear to you in the extreme flow setup is the total
sum and the result of multiplying the rate by the number of people in the number of manholes
multiplied by an equation. This equation is determined by the total number of people and after you
choose it, this equation is applied to all manholes because you control the total number. This is natural
because the equation that I multiply by the total number is a common factor taken for all manholes.

59. we can add

different scenarios, choose
child alternative to get a copy
of all your current properties

Then, create a child scenario change it is active topology because we

Will control active or inactive the new

Scenario network
 60. you can make you base is sewer as example and
the scenario is sewer + storm as example

61. but it is important that to change the solver

method to not get to different diameter, go to
home and option the make new solver

The Base is Design

And the scenario is Analysis , it is important that to back to scenario and add the new solver
It is important to add your equation to
your solver also
62. and the load is also different for the combine
system

63. you can double click at any pipe then specify it is local constrain

or you can edit group or edit flex table

 64. if you by mistake add or
import a point and there is a point that
are not connected to the network so
this will appear at this table

Or duplicate pipes over each other

65. after import also to find the

problem or error with branches that
connected to the main

Before import form cad

do (over kill command) in AutoCAD

To fix the manhole after impot go to tools

 66. now let’s make a surface to get your manhole
level, open your drawing and select similar these
points together then isolate

67. then use (Move text to elevation) command to

convert all of this text to elevation

68. in Autodesk AutoCAD Civil 3D use the Tool Space to create new
surface
69. based on your text you have create a surface

70. export as Landxml

71. import it in Sewer GEMS

 72.if you add new points or you want to modify
some points just choose this point and make a selection set

So when you import your new Landxml don’t select all but
select Selection set

73. to print out your work it is preferred that to not make too much annotation but using color code for
each diameter and legend instead

after you finish you can add this legend to drawing

74. we use Dxf to export to AutoCAD and use this
setting

75. you can also create new profile (shortest path)

Start with outfall and end with manhole, then open engineering profile
76.
77. Or you can make it Auto Create Profile, and do this setting

78. to reach re-number or rename your path go to views tap then Queries

Choose your first and last point

click okey
79. then edit group
 80. if you want to delete manhole don’t click on it then delete

But click on pervious pipe and do

reconnect

Then you can delete the manhole easily without error

81. to change invert level for specific point make Design start invert false

Then you can modify but it is important to make

set invert to start is false
