Sump pumps are prohibited from discharging into the sanitary sewer. However, annually during winter months in freezing conditions (October 15 through April 15) all homes and businesses with operational sump pumps may make request for a variance that permits the discharge of sump pump water into the sanitary sewer (City of Watertown Ordinance 17.0402 (1) (o)).
Written notices of variance will be granted as necessary in October each year. The seasonal variance will be issued for a specific period and must be renewed each year. If you have such a need, please make your request to the Wastewater Treatment Facility by clicking here and completing the request form. You may also call the Wastewater Treatment Facility at (605) 882-6244 to request a variance.
