Water Meter Sizing

[Timber]

I'm looking to size a water meter for a small warehouse/office complex. Approx 20,000 SF. If anyone has a copy of the above referenced fixture, please share this with me. I cant find it on the internet.

Thanks,

Timber

I did a water meter project a few years back. I think for a facility like that, we called out a 1" meter.

I agree that a 1" meter will do the job, provided the demands dont exceed 50 gpm. The thing is, I got an RAI (Request for additional info) from my local regulatory govenment agency, and trust me they want some proof, you know. So anyhow, I figured a nice spreadsheet comparison analysis between the proposed fixture unit counts, provided to me by the architect and the anticipated demands from each fixture, based on the AWWA M22 manual would put this to rest. The RAI is of course reasonable, only problem is, I dont have a copy of the M22. Anyhow, I'm confident the 1" meter will suffice, just need to locate a copy of that figure.

Thanks for the response.

only problem is, I dont have a copy of the M22.

I find fixture counts to be way high in estimation of flow. There should be other estimation methods that are OK with your regulatory agency. There should be a list in their code. All of these acceptable reference materials are also available at our regulatory agency's office for public use.

There's a table in the Uniform Plumbing Code (UPC) as well. UPC 2000 calls them "Water Supply Fixture Units"

A little tip - be sure to find out what type of toilet they're using - a tankless toilet needs much more flow & pressure - got burned on that one when a client provided insufficient info.

*yikes* I see this is a VERY old post. As you can see from my post count, I'm new - didn't realize these boards were slow.
