I understand that the District cleans the wastewater and returns it to the Bay. What happens to what is left?
Sewage flows from houses and businesses through sewer pipes to the sanitary district, where it is filtered and cleaned. Once the water has been removed, it is cleaned and released back into the Bay. What’s left is called sludge. Sludge is then disinfected and converted to a biosolid. The District currently produces about 20,000 cubic yards of biosolids each year.
