Delavan Lake Sanitary District....Serving the Residents of the Delavan Lake Area!

The Delavan Lake Sanitary District was created in 1969 to operate and maintain a wastewater collection system serving properties adjacent to and surrounding Delavan Lake. Since 1997 the District has been responsible for the Aquatic Plant Management Program for Delavan Lake as well as various lake monitoring projects and studies in cooperation with Wisconsin DNR and USGS. Since 1995 DLSD has assisted the Town of Delavan in the monitoring lake levels and operation of the Delavan Lake (Borg) Dam facilities.
