Napa to design pipeline to deliver recycled water for land irrigation use

Napa County will design a pipeline that could eventually deliver recycled water to the county's water-short Milliken-Sarco-Tulocay area, officials announced.
The proposed pipeline would deliver recycled water for irrigation use by large-volume water users who have voluntarily agreed to participate.
Past U.S. Geological Society groundwater resources studies in the area showed groundwater levels have declined over the past 60 years, county officials said. This has rendered some wells less productive or unusable, causing some landowners to dig deeper wells, they said.
The unincorporated Milliken-Sarco-Tulocay area gets no water or wastewater services, so solving its water shortage issues is a Board of Supervisors priority, they said.
Napa Sanitation District will supply the recycled water once a pipeline is built. Recycled water is wastewater that has been highly treated and disinfected to provide a safe, non-drinkable water supply. Recycled water is already used locally to irrigate vineyards, golf courses, pastureland, parks and landscaping.
