Determining new PS capacity w/ consideration of additional discharge from an existing PS
Determining new PS capacity w/ consideration of additional discharge from an existing PS
(OP)
We were tasked to design a new pump station that will discharge into an existing (common) 4” forcemain that runs past the new PS site. I have checked the existing pump station upstream and with our new station running it appears that the existing pump station will be locked out. We’re not a big fan of common forcemains so our solution is to modify the existing FM to dump into our new receiving manhole. We'll then connect a new FM from our new station to the existing FM. We'll then size the new pump station to pump the existing pumps design discharge + 1.8 x calculated new sewer inflow. In addition we’ll look at 2.5 x new area inflow with no additional flow from the existing pump station. I would be interested to hear others opinions/remarks.

Bimr - For this project the minimum peaking factor 2.5 is dictated by the state regulatory agency. I was just wondering how others might be handling flows pumped from another pumping station into a new station coupled with the flow from the new area.
