Stormwater Utility

Print

The goal of the Stormwater Utility is to provide a stormwater drainage system with adequate capacity to accommodate major storms while maintaining the quality of stormwater discharged into receiving streams and rivers. The Stormwater Utility provides for the collection and conveyance of stormwater within the City through the use of public streets, catch basins, storm sewers, detention/retention basins and greenbelts.  The system is comprised of over 160 miles of storm sewers, 15 miles drainage ways (including greenbelts) and 13 detention/retention basins. The Utility serves all properties within the City and the cost of operation and maintenance is supported through user fees, which are due and payable quarterly on the combined water, wastewater and stormwater billing.

This program provides for five sweeping cycles in residential areas and six cycles for downtown street and main arterials.  The spring cycle removes the accumulated debris from the winter and the fall cycle follows leaf collection.  In addition, catch basins and storm sewers are cleaned routinely and repairs to the collection system are performed as needed.  This program also includes maintenance and erosion control activities for the greenbelt system and detention/retention basins.

The City is required to control the quality and quantity of stormwater runoff in accordance with Federal and State requirements.  Compliance with the City's erosion control ordinance will require review and monitoring of stormwater runoff of new developments during construction.  In addition, development plans will be reviewed for post construction compliance with the City's Stormwater Management Ordinance.

The street is flooding with water.  Can you do anything to help?

Call the City Services Center at 755-3110 weekdays between 7a.m. and 4p.m. with your name and address.  We will refer your concern to a foreman, who will look into the problem.  If we find the catch basin or storm sewer plugged, we will dispatch a crew to clear it.  Most of the time, leaves, grass clippings, sticks or cardboard is blocking the top of the catch basin, which we clear away.  If the flooding occurs after 4p.m., please call the Janesville Police Department at 757-2244.
