Ceremony to Celebrate Recycled Water Projects

April  19, 2016

When:  Monday, May 2, 2016 ~ 10am to Noon

Where: Napa Sanitation District, 1515 Soscol Ferry Road

Who: Speakers and attendees will include Congressman Mike Thompson, City of Napa Mayor Jill Techel, State and Regional Water Board Staff, US Bureau of Reclamation Staff, North Bay Water Reuse Authority Board Members, Napa and American Canyon City Council Members, County Supervisors, Napa County Staff, Los Carneros Water District Board, Napa Sanitation District Board and Staff, recycled water pipeline customers, and other partners instrumental to the completion of these projects.

Why:  At the Napa Sanitation District (NSD) treatment plant, major investments were made to expand the treatment process to accommodate increased recycled water demand and distribution in southern Napa County.  The sand filter system was expanded and an equalization basin was constructed to provide a constant flow of water to the filters and increase filter efficiency.  The recycled water pump station was expanded and enhanced to provide different pressures in the system and increase distribution capacity.  A dissolved air flotation (DAF) clarifier was built to increase treatment capacity.  Together, these projects will allow NSD to increase recycled water production from 2,000 acre feet to 3,700 acre feet per year.

We are celebrating three separate projects that provide benefits to the residents and water users of Napa County.  The first project is a series of upgrades to the NSD waste water treatment plant to supply high-quality recycled water.  The second project is the construction of the 5-mile Milliken-Sarco-Tulocay (MST) Recycled Water pipeline that was done in partnership with NSD, Napa County and local land owners. The third project, takes water from the NSD treatment plant to property owners in the Los Carneros Water District who constructed their distribution pipeline in partnership with NSD.  All of these projects will contribute to reduced demand for groundwater and save potable water from being used for irrigation.


About NSD and their recycled water: The high-quality recycled water will come from the Napa Sanitation District Soscol Water Recycling Facility.  Recycled water is wastewater that has been highly treated and disinfected to provide a safe, non-potable water supply. NSD’s recycled water meets the stringent water quality guidelines set by the California Department of Public Health.

Napa Sanitation District provides wastewater collection, treatment, and disposal services to the residents and businesses in the City of Napa, Silverado Country Club, the Napa County Airport and several adjacent unincorporated areas. NSD also provides recycled water service to portions of southern Napa County and is a member of the North Bay Water Reuse Authority. Covering 20 square miles, NSD has been serving the community since November 1945. For further information about the District, please see www.NapaSan.com.
