Water Distribution Network Software
Water Distribution Network Software
(OP)
We are in need of water distribution modeling software that will enable us to model water distribution networks to determine fire flow. We will be using the software for determining fire flow at hydrants in subdivisions and any time we extend a water main. I was wondering what software you all would recommend. Thank you.

good luck

The only reason we used WaterCAD was that the city had purchased it and was modeling their entire network with it.

As a work around I have calibrated a node by setting demand to actual test flow and adjusting the roughness coefficient (trial & error) of the pipe feeding the node until I could approximate the residual pressure observed in the test. It shouldn't be necessary to do this but the documentation on creating calibration files is poor and I've never been able to master it. Question: is the above a reasonable method for a simple network or do I need to learn how to write a calibration file?.
I have a project where a new building system is connected to an existing 8" waterline extension. The fire department wanted 2000 gpm with a 150% safety factor or 3000 gpm. They stopped the test at about 2500 because residual pressure was dropping below 20 psi. The contractor wants me to investigate replacing the existing waterline (not desired) or looping in a connection to another existing 6" line. Initial modeling indicates it wont work, but my model predicted substantially worse performance of the existing 8" connection than the test achieved.
