The City of Santa Rosa’s Water system consists of over 600 miles of water main ranging from 4” up to 24”.  The City water mains are supplied by over 30+ turn-outs from the Sonoma County Water Agency (SCWA) aqueduct. Pipe materials differ over the years from cast iron, ductile iron, concrete cylinder, AC, C-900 (PVC pipe). Standards now include ductile, C-900 and concrete cylinder when specified.

Over 50,000 water service connections provide water service to both commercial and residential customers. Sizes range from ¾” to 1” copper for residential use and 2” copper pipe to 4”and 6” C-900 or ductile iron pipe for commercial use.

The water system is maintained by three Local Water Construction crews that are responsible for making all the needed repairs in a timely manner. Every effort is made to insure the delivery of safe drinking water with a minimum interruption to our customers.
