Peak rate factor
Peak rate factor
(OP)
I am designing a sewer trunk line to serve a sewer system. The prison will have 3000 beds. Any idea on what peak rate factor to use for this?

PF = 3.81(ADF^-0.16) for maximum instantaneous flow rate
PF = 2.28(ADF^-0.12) for maximum 24-hour flow rate
ADF is Average Daily Flow in MGD

good luck

Inmates are famous for devising ways to clog the sewer system. Rags, clothing, trash, mop heads ( explosives if they can get them )and all similar means are seen as weapons of mass confusion and distraction at prisons, mental hospitals, etc. I live in a State capital home to about ten such facilities. For this reason your local sewer system provider may require trash racks, inspection and metering manholes and other safeguards on any system you build. Such things make a joke of even the most careful calculations.

I will add that prisons are also famous for consuming large amounts of water. Prisons may also have special plumbing systems. For example, the fixture water supply is typically controlled with push buttons instead of knobs, for obvious reasons. Newer prisons will use less water than older prisons because of more modern plumbing fixtures.
As RWF7437 suggested, you should survey nearby prisons with to obtain the most accurate water data.
