5th Street East Recycled Water Pipeline

sv-recycled-water-diagram.jpgProject will bring recycled water to Sonoma Valley High School.

The Sonoma Valley County Sanitation District (SVCSD) has finished construction of a recycled water pipeline that will send water from the SVCSD wastewater treatment plant on Eighth Street East to Sonoma Valley High School. The recycled water will help irrigate the playing fields at each school, offsetting potable water used for irrigation and providing high-quality, cost-effective, and sustainable drought-proof water. A number of residents along the pipeline route will also be receiving water from the pipeline for irrigation.

Project Facts

  • Miles of pipe to be constructed: 1.5
  • Pipeline path: Pipe to be installed along Watmaugh Rd East of Shainsky Rd to 5th Street East, then North along 5th Street East to Denmark Street and continuing west along Denmark Street to Sonoma Valley High School. A small section of pipeline will also be installed from Denmark Street along Engler Street to irrigate the neighborhood park.
  • Type of pipeline: PVC


The total cost of the project is approximately $3 million. The project has been awarded to receive $1.02 million funding grant from the California Department of Water Resources Proposition 84 through the Bay Area Integrated Regional Water Management Plan. The remaining cost will come from leveraging other grant programs and the District’s capital improvement budget.

What is recycled water?

Water is continually recycled in nature through the water cycle. Modern wastewater treatment replicates the natural recycling process to restore large quantities of water quickly and effectively. In Sonoma, water from showers, sinks and toilets inside homes and offices travels through pipes to the Sonoma Valley County Sanitation District (SVCSD), where it is treated to tertiary recycled water standards (also referred to as advanced wastewater treatment), which is the highest level of treatment defined by the State of California, Department of Public Health (Title 22). The wastewater goes through primary treatment, biological treatment, filtration, and disinfection before it is considered tertiary recycled water.

Why use recycled water? 

For every gallon of recycled water that is used, a gallon of potable drinking water is saved. Utilizing recycled water for urban and agricultural irrigation helps offset potable water use and provide a high-quality, cost-effective, and sustainable drought-proof source of water. 

How is recycled water currently used?

Tertiary treated recycled water is safe to use for the irrigation of agricultural crops, vegetable crops that are eaten raw, vineyards, playgrounds, golf courses, parks, cemeteries, and many more urban uses. In Sonoma County, recycled water is used to irrigate agriculture, lawns at school playgrounds and parks, in decorative fountains, and in residential landscaping.

Recycled water is used in many places and for many uses around Sonoma County. Recycled water is used across Sonoma County for agriculture, including vineyards and other crops in Sonoma Valley. Some cities in Sonoma County also used recycled water for their playing fields. In Windsor some residential neighborhoods use recycled water in their landscaping. Some other recycled water uses around Sonoma County include:
