Exceptional Waste Discharge Permit

This permit is required for temporary discharges to the sanitary sewers. These permits are typically for construction project groundwater dewatering discharges or draining of large pools (>20,000 gallons).

This permit is issued by the Regional Water Quality Control Plant for facilities located in Palo Alto. The permit is dependent on where the discharge is planned to occur. If your facility will be discharging in a jurisdiction besides Palo Alto, you need to contact them for a permit.
