Water Quality Analysis

KYPipe provides a straightforward interface to the EPANET program to perform water quality simulations on an existing hydraulic network model.

Through this EPANET interface it is possible to:

  • Calculate chemical concentrations (e.g., chlorine).
  • Determine water age (residence time).
  • Trace a chemical from a source.

Water Age calculations can be used to meet the Initial Distribution System Evaluation (IDSE) requirements for the Environmental Protection Agency (EPA) Stage 2 Disinfection Byproducts Rule (DBPR). The hydraulic model option, or System-Specific Study, can be much less expensive than the alternative Standard Monitoring option allowed in the EPA guidelines.

Through the interface with EPANET, KYPipe is able to import and utilize models from a variety of sources sharing the EPANET data file format.

Below is the KYPipe Water Quality Menu which allows users to set simulation specifications and chemical reaction rates. Also, source (reservoir) chemical concentrations are set within this menu.

Below is an animation of a chlorine analysis over 72 hours. Animations can be exported to AVI, MP4, GIF and other formats.

Next is an image showing a trace of chlorine concentrations in an overhead storage tank in a 150-hour simulation. The chlorine amount varies based on the diurnal demand cycle and the pump operation over a 24-hour period.
