SRCSD has developed a diversified biosolids management program that is both environmentally friendly and of high value to rate payers. This program is two-pronged, consisting of both recycling biosolids into environmentally beneficial products and applying biosolids to land disposal units. (Click here to see Processing Split Diagram.)
Each year the Sacramento Regional Wastewater Treatment Plant (SRWTP) processes 26,000 dry tons of biosolids, making the program one of the largest producers of biosolids in California. Approximately 70 percent of those biosolids are treated and then injected into on-site land disposal units. The remainder is beneficially recycled at the District's Biosolids Recycling Facility (BRF).
Biosolids are rich in nitrogen and contain phosphorus, potassium and micro-nutrients, all necessary to the growth process. As a fertilizer, biosolids retain soil moisture, helping to reduce soil erosion. As a soil enhancer, biosolids can be marketed as dry, pelletized, odorless fertilizer; as green waste compost in which the biosolids are mixed with natural plant materials; or as the garden-variety compost.
A continuing component of the SRCSD's Biosolids Management Program includes ongoing community outreach. The SRCSD is continuing its efforts to educate the public, farmers, and community leaders on the benefits of biosolids recycling, which can be done safely and effectively.
