Pretreatment Regulations


Central San’s Environmental Compliance Program uses a combination of regulatory and educational elements to minimize the pollutants in all process wastewater discharged to the sanitary sewer system from commercial, retail, agency, and industrial customers. Central San’s Source Control Ordinance (Title 10 of the District Code) applies to all non-domestic customers.
