Water/Wastewater Peaking Factor for Schools
Water/Wastewater Peaking Factor for Schools
(OP)
I am doing a water and wastewater study for a rather large school campus. Its a public school campus for K - 12. Does anybody know of some published information for a peaking factor for a school? It just seems to reason that it would be somewhat higher than for a typical municipal system.





RE: Water/Wastewater Peaking Factor for Schools
You could use the 10 States formula, which for a school of 1000 would yield 3.8. However, 10 States is based on residential populations which would have a lower peak than a school.
What peaking factor were you thinking of using?
What is the population of the school?
What are you allocating for per capita average daily use?

Out of curiosity, how does the historic data compare with the per capita you would have to use otherwise? Is it higher or lower?
I would probably use 5 for a peaking factor in this case (10 states for 3000 capita + 50%=5.16). I would consider using a higher peak if there was a large discrepancy between the historic flows and what I would expect using per capita charts in the state code.

See Piping Handbook by Nadyyar, Published by McGraw Hill.
Many schools are eliminating locker room showering facilities now anyway. Most new buildings are using low flow fixtures as well.
There is no need to be conservative.
