The fee for obtaining a seasonal sump pump variance is $125 annually, which includes a $25 application fee. The seasonal sump pump variance period will normally be from October 15th to March 15th each year. The ending date of the variance period may be modified if the Wastewater Superintendent deems it appropriate and/or necessary. Please be aware, you may be required to valve your sump pump discharge out of the sanitary sewer prior to March 15th.
Applications for a sump pump variance will be accepted on October 3, 2022, however discharging to the sanitary sewer is not approved until October 15, 2022. To obtain a sump pump variance over the phone, call 605-882-6244. To request the variance online, complete the form found at http://www.watertownsd.us/variance. If a current inspection of your property is not on file, Wastewater Staff (a division of Public Works) will schedule an appointment to inspect your sump pump system before a variance will be granted.
Once an inspection has been conducted and the sump pump variance has been granted, the City’s Finance Office will mail you a bill for the $125 fee. Payment is due 30 days from billing.
You must apply for a sump pump variance each year that you wish to discharge a sump pump to the sanitary sewer.
Discharging clear water (sump pump discharge) into the sanitary sewer is prohibited unless a seasonal variance has been granted (Ordinance 17.0402 (1) (o)). Sump pumps may not discharge to the sanitary sewer when the seasonal variance period is not in effect (normally between March 15th and October 15th).
