2. EPANET
A computer program that performs extended period
simulation of
hydraulic and water quality behavior within pressurized pipe
networks.

3. HYDRAULIC MODELING
CAPABILITIES
Ability to model:
• Small and big size-Networks
• Constant or variable speed pumps
• Pump efficiency
• Pumping energy costs
• Tanks with any shape (volume curve)
• Valve regulation (PRV-PSV-PBV-GPV-FCV-TCV)

4. QUALITY MODELING CAPABILITIES
• Blending water from different sources
• Age of water in the system
• Loss of chlorine residuals
• Tracking contaminants propagation
• Growth of disinfection by-products
• ………….

5. PIPE NETWORK
network
Nodes
reservoirs
Tanks
Junctions
Links
Pipes
Valves
Pumps

6. STEPS
• Project setup
• Draw a network presentation
• Edit Objects properties
• System operation description
• Select a set of analysis options
• Run a hydraulic/water quality analysis
• View the results of analysis

7. EXAMPLE NETWORK

11. 1.PROJECT SETUP

12. 1.PROJECT SETUP

13. 2.DRAWING THE NETWORK

14. 3.SETTING OBJECT PROPERTIES
• Double click on the
object, OR
• Right click on the object
and select [properties]
Fill in properties from 1st to
the last object!

15. NODES AND PIPES PROPERTIES

16. PUMP CURVE
Browser(Data)
Curves
Add

17. 4.RUNNING A SINGLE PERIOD ANALYSIS
• Project >>> Run OR Click “Run” Button.
• Check for Results:
-Select Node pressure from Browser’s Map page.
- Double click on any Node.
-Click Report >>>>>Table.
Remark: Flows with negative signs means that the flow is oriented in the
opposite direction.

19. RUNNING AN EXTENDED PERIOD ANALYSIS
• Create time pattern (6hours)
-Browser(data)-Options(times)-Edit
[Total duration:72h and Pattern
time step:6h]
-Browser(data)-Patterns-Edit-enter
the multipliers- OK
-Browser(data)-Options-Hydraulics-
edit- default pattern:1- RUN
.

20. NOWTHE RESULTS CAN BE
PRESENTED IN AVARIETY OFWAYS.
• Pressure: node parameter
• Flow: link parameter

21. .
• Create a time series plot for any node or link.
- Click on theTANK-Click Report>>Graph-select time series-select Head as
Parameter- OK!!

22. RUNNING WATER QUALITY
ANALYSIS
• Transport and Decay of Chlorine through the network
❖Browser>>Data>>>Options>>>>Quality>Edit>
Parameter: CHLORINE
❖Options>>Reactions>>Global Bulk coef: -1
❖Click on reservoir node>> Initial quality:1
RUN the analysis

23. USETHE MAP BROWSER TO SEE HOW
CHLORINE LEVELS CHANGETHROUGHOUT
THE SYSTEM

24. CREATE A REACTION REPORT BY
SELECTING REPORT>>REACTION
.
