The City water system serves approximately 9,200 residential, 800 commercial, and 400 irrigation customers within the City of Paso Robles. The Paso Robles Water Division (PRWD) is committed to providing customers with a reliable high quality water supply. There are 11 full-time staff to operate and maintain 19 wells, two arsenic removal treatment systems and one micro-filtration water treatment plant, six booster stations (used to pump to higher elevations), four reservoirs (providing over 12 million gallons of storage) and 172 miles of water main. To ensure water quality is continuously maintained, PRWD adheres to a rigorous sampling and laboratory-analyses program in accordance with state and federal drinking water laws.
PRWD maintains the distribution system, fixes leaks, installs customer connections, and fire hydrants. The crew works closely with contractors to monitor and enforce the City’s specifications for water system construction, performs plan checks for new developments and inspects installations.
Other responsibilities include monitoring and enforcing the City’s cross-connection program. A cross-connection is a connection to any part of the public water system containing water or any substance that is not or cannot be approved as safe, wholesome, and potable for human consumption. Currently, the City requires backflow devices to be placed on all commercial and irrigation meters to protect the City’s water supply from possible contamination. The State requires testing of all backflow devices on an annual basis. The County of San Luis Obispo assists the City in this program by sending out test forms to owners and the City enforces testing requirements to ensure that all devices are tested annually.
