Hey everybody,

Working on a project where we will be constructing a transmission main to connect to a storage tank who’s primary source is from a surface water, where we’ll use their supply to assist a neighboring community with ground wells that frequently dry up.

How will the qualities of these two different sources blend? How do you know what to test for?

What else should we be on the look out for?

I have a water system that feeds two tanks. One tank feeds a regional line downstream to other communities, and the other is a storage tank that provides water and pressure to the same municipality that is supplying water to the regional line.

The water treatment plant has 3 high lift pumps that push this water into the distribution system, which is connected to both tanks — so some water is consumed by the distribution system and some by the tanks.

I've been tasked with modeling part or all of the regional line. Is it necessary to model all of it? How would I determine where to stop?
Also — why is it critical for me to know what is happening downstream of the regional line tank, and how could that affect the WaterCAD model of the select streets I'm targeting within the village?

Also, is it critical to model the 3 high lift pumps that initially pump all the water from the plant and feed both tanks, but also lose some water in the distribution system through interconnections on its way to filling the main storage tank that's responsible for the entire village — or is it conservative enough to consider that the main storage tank could act as the primary pressure source for the village?
