  • Municipal Water Reuse Done Right Lessons In Efficiency
    potable reuse process We selected this technology in anticipation of potable reuse should it become a treatment option as the first step in that process he said The Napa Sanitation District NSD has leveraged its participation in the NBWRP to fund a portion of its expanded recycled water facility The district produces about 2 200 AFY of tertiary quality recycled water that it distributes to nearby customers for irrigation of golf courses industrial and commercial landscaping schools and parks The NSD also uses recycled water on its own property to raise fodder crops All of the wastewater at the NSD plant receives secondary treatment utilizing both activated sludge and pond treatment methods For the tertiary quality recycled water the NSD expanded its capacity by adding additional Dynasand continuous backwash sand filters to its existing system After going through the sand filter treatment the recycled water receives extended chlorination The facility is designed with the capability of adding additional components as demand for recycled water increases To date the NSD has spent 15 3 million on the project and received 2 1 million federal and state funding It anticipates additional federal grant funding for the project Storage Is A Key Component Because demand for recycled water is greatest during the dry summer months storage during off peak months is a critical component of any water reuse program In Phase 1 the Sonoma Valley County Sanitation District completed a reservoir storage project that provides storage of up to 100 acre feet of water that can be used on a year round basis by grape growers The Sonoma Valley system also includes two large storage reservoirs with a capacity of 355 acre feet that can be used for vineyard irrigation and it also provides water for habitat enhancement for wildlife including a variety of waterfowl and other birds The NBWRP s next phase will include a greater emphasis on storage with as many as 18 storage projects in the planning stages including projects that will again integrate multiple benefits into their design For example a storage pond could provide habitat enhancement for wildlife protection against sea level rise assist with groundwater recharge and provide community recreation and open space Recycled water is distributed to a variety of locations in the program area for a variety of uses The Novato Sanitary District and the Las Gallinas Valley Sanitary District treatment facilities both provide water to the North Marin Water District where it is distributed to its customers for irrigation landscaping parks playgrounds and a golf course Environmental Benefits For Fish And Wildlife The NBWRP has gone beyond the traditional uses for recycled water by including a significant habitat restoration project the Napa Sonoma Marsh Restoration Project This is a multiagency effort involving the Sonoma County Water Agency Sonoma Valley County Sanitation District California Department of Fish and Wildlife the Army Corps of Engineers the state Coastal Conservancy and federal Bureau of Reclamation Recycled water from the Sonoma Valley County Sanitation District will be used
