fyi: we have performed some additional investiagations, here is what we have found. 1. this wet well mounted station has a vacuum pump that lifts the column and diplaces the air in the stem pipe. according to manufacturer, it should only run a couple of seconds, because their should only be a...
The easiest way is to use SewerCad. We use this on multi-pump, multi-forcemain analysis.
It allows you to plug in the pump curves, geometry, etc.
1. do an existing system analsis. Determine what the pump run times, operating points are.
2. do a proposed system analysis, your new pump...
when we calibrate our watercad models, the most important thing the getting the elevation of nodes correctly. This would require GPS'sing their locations. Next we also use continous digital pressure loggers at key points in the system. These will give you the daily pressure, and tell you how...
we use sewercad for multi-pump station and forcemain analysis. Also, the last low pressure sewer we did, the manufacturer actually did the study. I beleive they used KYPIPE.
This is a wet well mounted pump station, pumps are mounted on top of the wet well, there are two stem pipes that extend down into the wet well. After the pumps shut off, should the sewerage in the lift pipes stay in "suction" or should it drain back out? If they drain back out, and the pumps...
I have a 8 inch force main (from a pump station about 1 mile away) that discharges into the effluent channel in a treatment plant. WE have a problem where when it the pumps stations are running, sewereage spew into the air, several feet high, (up to 10 to 12 feet), splatters, if you are anywhere...
