Great input everyone. I agree that once on the "building side" of the regulations, that the building code will govern. As I look at the NYS plumbing code - it states that a booster pump is required when "public water main is insufficient to supply minimum pressures specified in the code"...
Thanks bimr. The requirements for providing fire flows and pressures to a building on fire are clear to me. What I am struggling with is providing adequate pressure to upper floors of high rises while a nearby low rise fire is occurring and its(low bldg) fire flow demand is lowering residuals...
Thanks cvg. I understand that 10 States generally applies to municipal systems, but I am of the opinion that this campus is really in and of itself somewhat of a municipal system.
It doesn't have a treatment works, but it certainly has miles of distribution piping, large industrial and...
I am evaluating a water distribution system on a college campus in New York and am struggling with pointing to a regulation that stipulates required residual pressures that need to be maintained during fire events. In particular - maintaining residuals in the system while a fire is somewhere...
Thanks for all your responses to my question. Let me clear a few things up.
1) The pump station will be a retrofit of an existing pump station and the pumps will be operated by VFDs. During high flow conditions, the VFDs will attempt to maintain a wet well level such that they match influent...
I am evaluating the feasibility of using an inverted siphon to convey sanitary flows below a creek and the hydraulic calculations suggest it will work, although I have pulled out all the stops to get it to work. I'd feel much more comfortable if there was a bit more cushion in the design so I...
