Delivering Safe, Reliable, and Affordable Drinking Water


There is no impact to the safety of the drinking water delivered to City of Fresno water customers.  The City’s water treatment plants are designed to eliminate pathogens, including viruses and bacteria, and the City maintains an appropriate level of chlorine in the distribution pipes to ensure the water stays safe as it travels to homes and businesses. The City continuously monitors and tests drinking water, and the water always meets or exceeds every state and federal requirement that safeguards public health.

The City of Fresno delivers drinking water to approximately 500,000 residential, commercial, and industrial customers over a 114 square mile are of the city including many county Islands.

The City of Fresno runs numerous treatment facilities that disinfect and remove synthetic organic contaminants at various well sites.

Water Meters

Fresno receives 60,000 acre-feet of high-quality water annually from behind Friant Dam. To comply with the terms of the Central Valley Project (CVP) water contract with the U.S. Bureau of Reclamation that supplies this water, the City of Fresno is required to measure (meter) all water deliveries to customers. As a result, Fresno was mandated to install water meters, and bill by a volumetric rate, all of its residential customer accounts by January 1, 2013.  Commercial and multi-family accounts were already metered and billed at a metered rate.

In order to comply with the terms of the contract and state law, the City installed water meters at all single-family residences that did not already have meters. The multi-year installation project started in 2008 and was completed in December 2012.
