Water Meter Size
Water Meter Size
(OP)
I need to know how to calculate the size of a water lateral
enterring several different types of buildings in a new development, ie. single family, condo, duplex. I have the fixture demands for each unit but the total required capacity is a lot higher than I need. As an example a single family unit using the fixture count (30 gpm) will need a 1.5" meter. Isn't a single family unit usually supplied with a 3/4" lateral? Is there a weighted fixture demand?

RE: Water Meter Size
For the multi-family and commercial buildings or for the single family dwellings with an unusual condition, follow the sizing procedures and guidance in “Sizing Water Service Lines and Meters” (AWWA Manual M-22).
RE: Water Meter Size
The community where I live is now going with 1 1/2 inch water service as standard for single family residences unsprinklered. Go figure.
Note also that some municipalities are now requiring fire sprinkers in new construction which will also require larger than 3/4 inch water services.
