LOW PRESSURE FORCEMAIN
LOW PRESSURE FORCEMAIN
(OP)
I am doing a low pressure force main with multiple grinder pumps feeding into the forcemain at different points. I have done many forcemains from one lift station source, but never a multiple pumps on the same line at different entry points.
Just wondering if there are any things I need to consider that you wouldn't look at on a tradional lift station forcemain.
any thoughts would be appriciated

Also, I would be surprised if any permitting agency would allow less than 2.0 fps, but I would check before investing any time into it.
Just keep in mind that some utilities with low pressure systems use PVC, SDR 21 pipe. This means you can actually use pipe diameters ranging in 1/2-inch increments from 1.5-inches in diameter and up through 3.5'inches. 4 and above just use C-900.
One of the largest low pressure systems in the USA is in the City or Port St. Lucie, FL and they use Myers exclusively. Their specs should be useful if you want to see what they use for fittings as well.
