Recycled Water

Walnut Valley Water District operates a recycled water system to irrigate landscaped areas along freeways, sports fields, parks, medians, school grounds, commercial properties, and community association property.

Recycled water is the official name given to wastewater that has been extensively treated to be reused or repurposed. Recycled water is a reliable and cost-effective way to reduce our dependence on imported drinking water and is completely separate from WVWD’s drinking water system. Recycled water is not meant for consumption by individuals or pets.

WVWD delivers 763 million gallons of recycled water annually. Recycled water is drought-proof and can be easily identified by the purple pipes and signs. Learn more about recycled water in your community by clicking on the factsheet below.

History Of Recycled Water In Your Community

Walnut Valley Water District completed its original recycled water system in 1986. Recycled water from the Pomona Reclamation Plant began to irrigate large landscaped areas. The original system included:

  • 17 miles of pipeline
  • 2-million-gallon storage tank
  • Recycled pump station
  • 21 connections serving 340 acres of land

Over the years, WVWD has expanded the use of recycled water to include a recycled water well that was completed in 1989 which pumps groundwater from an underlying basin and produces an average of 330 gallons of recycled water per minute. In 1992, WVWD doubled its recycled water storage capacity with the addition of an additional 2-million-gallon storage tank. In 2003, the second recycled water well was completed and produces an average of 155 gallons per minute.
