Need Recommendation on Water System Network Software
(OP)
I need to model a water system where there is a tap off the City distribution network and then I create a separate looping water system network on private property serving fire hydrants building, etc. on a 200 acre site. What software would you suggest for doing this modeling to ensure the size of water piping I am using is correct and water quality will be maintained, provided the City will give me the available static / dynamic pressure of the line I will be tapping. Thanks.

Bentley (nee Haestad Methods) use the same engine but have an improved front end.
AFT's Fathom can model networks and has a module for extended period simulation for use in sizing reservoirs a and distribution networks.
There are many others out there.

1. If I am tapping into large diameter City transmission and distribution mains at two locations that will serve a grid of mostly fire protection piping to hydrants across a 200 acre site, should the taps to the existing system be modeled as reservoirs with an elevation that is consistent with the pressure at the main? If not has should this connection be modeled?
2. Most of demands across the site would be for fire, both hydrants and building sprinkler systems. There are also minor domestic demands. So, obviously all the hydrants will not be flowing at the same time and all the demands will not be simultaneously occurring at once. How do I decide on what demand occurs when, or is that something dictated by the City and/or Fire Marshal?
3. If the domestic demands are very low, should a separate piping network be used for domestic and fire? Using "age" as a water quality indicator, how old is too old for water serving domestic needs?
Thanks so much in advance for your help.

2) The city fire department would have that criteria.
3) Separating the fire and domestic is typical for private systems I have worked with, as for what age is ok, check with the City, who will know the charateristics of the source. There are many variables here, temperature, how the disinfectant behaves with time, the type of disinfectant, (free chlorine, monochloramine, chlorine dioxide), the about of chlorine demand, regrowth potential, has the water been exposed to air or light since treatment, type and age of pipe ect.

tell us what can KYpipe do that epanet cannot?
