The City of Watertown’s storm sewer system is designed to drain stormwater runoff to the nearest stream, wetland, pond and the Rock River. Only rain and snowmelt (with a few exceptions) is allowed in the stormwater sewer system per Article II, Chapter 453, Municipal Code. Clear water connections are allowed with an approved permit.

If you have curb that needs to be cut to allow for sump pump discharges to the street, a permit is required. Information on this can be found by clicking here.
