The City of Brentwood provides recycled water as part of its ongoing water conservation efforts. Recycled water, also referred to as non-potable water, is wastewater that has undergone advanced treatment and disinfection to meet stringent quality standards established by the California State Water Resources Control Board Division of Drinking Water. While not approved for drinking, this water is safe and effective for a range of non-drinking uses, including landscape irrigation and industrial processes.

How Recycled Water is Used

Brentwood’s investment in recycled water infrastructure began years ago with the strategic decision to install a citywide distribution system, commonly identified by purple piping. Today, approximately 41 miles of purple pipe run throughout Brentwood, allowing the City to use recycled water to irrigate public parks, medians, school grounds, and other large landscaped areas. This system plays a critical role in preserving potable water (drinking water) supplies, particularly during the hot summer months, when irrigation demand is highest. During peak periods, the system delivers up to 4 million gallons of recycled water each day.

Recycled Water Fill Station

Brentwood’s Recycled Water Fill Station, operated and maintained by the City’s Wastewater Division, allows eligible utility customers to collect recycled water for residential use at no cost. Residents may use this water for irrigating home gardens and lawns or washing outdoor surfaces. The maximum volume allowed per visit is 300 gallons.
