EPANET is software that models water distribution piping systems. EPANET is public domain software that may be freely copied and distributed. It is a Windows 95/98/NT/XP program. EPANET performs extended period simulation of the water movement and quality behavior within pressurized pipe networks.
Pipe networks consist of pipes, nodes (junctions), pumps, valves, and storage tanks or reservoirs. EPANET tracks:
- the flow of water in each pipe,
- the pressure at each node,
- the height of the water in each tank, and
- the type of chemical concentration throughout the network during a simulation period,
- water age,
- source, and
EPANET helps water utilities maintain and improve the quality of water delivered to consumers. It can be used to:
- design sampling programs,
- study disinfectant loss and by-product formation,
- conduct consumer exposure assessments,
- evaluate alternative strategies for improving water quality, such as altering source use within multi-source systems,
- modify pumping and tank filling/emptying schedules to reduce water age,
- use booster disinfection stations at key locations to maintain target residuals, and
- plan cost-effective programs of targeted pipe cleaning and replacement.
- plan and improve a system's hydraulic performance,
- assist with pipe, pump, and valve placement and sizing,
- energy minimization,
- fire flow analysis,
- vulnerability studies, and
- operator training.
