North San Mateo County Sanitation District (NSMCSD) is committed to protecting our environment. We endeavor to recycle and reuse the treated by-products of our plant, namely, treated wastewater effluent and biosolids.
California's limited water supply will pose greater challenges for our future, and the NSMCSD, in cooperation with others, will look for new ways to reuse water. The NSMCSD reclamation program began in the late 1980s in response to the drought and continues today to conserve a precious resource.
Water Recycling is a responsible solution to the growing demand for water. Recycled water is a smart alternative water supply source for the Daly City area due to its limited groundwater supply and increasing population. By using recycled water for non-potable (non-drinkable) uses such as irrigation, precious drinking water supplies can be conserved. Since the mid eighty's the NSMCSD has been installing recycled water pipes around the City when water or sewer projects are constructed.
NSMCSD also makes sure that biosolids are put to good use for safe land application and soil amendment. Reuse completes the cycle that leads to a sustainable future.
Our treatment process produces approximately 6 tons of dry sludge per day, all of which is recycled. During the rainy season the biosolids are used as daily cover at Redwood Landfill in Novato. During the spring and summer months it is used as a soil amendment for non-edible food crops in Solono County.
