Sump Pumps

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 Ordinances 17.0602 and 17.0603)

Please be advised that if you are identified as discharging unpolluted water and/or sump pump discharges into the sanitary sewer when the temporary seasonal variance period is not in effect or without a written variance during the temporary seasonal variance period you could be subjected to the criminal penalties associated with a Class 2 Misdemeanor, including up to 30 days in jail and up to a $500 fine. Additionally, each day on which noncompliance shall occur or continue to occur shall be deemed a separate and distinct violation.


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.
