This document provides an overview of EPANET software for water distribution system design and analysis. It summarizes EPANET's capabilities including hydraulic and water quality modeling. It also outlines the basic steps to set up and run an analysis in EPANET including drawing a pipe network, editing object properties, running single or extended period simulations, and viewing results. An example network is shown and the toolbars are described.

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

9. TOOLBARS
.

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
