Post

Central San issues Special Discharge Permits to businesses that have a temporary, non-standard wastewater discharge to the sewer system. In many cases, this permit authorizes the discharge at a specific location. Examples are: groundwater remediation discharge, dewatering operations at a construction site and pool, spa or fountain discharges. Special Discharge Permits may require the use of a pretreatment system and/or the sampling and analysis of the wastewater.
