About the Commission

The Delafield-Hartland Water Pollution Control Commission was created on December 23, 1971 by ordinances adopted by the City of Delafield and the Village of Hartland. The purpose of the Commission is to provide wastewater collection, treatment and disposal services for the designated regional service area encompassing such municipalities.

The Commission serves primarily residential users that now make up about 80% of its customer base.  The rest of the Commission’s users about 20% are made up of non-residential entities: commercial, industrial, institutional and governmental.  All of these residential and non-residential users come from the five customer municipalities of City of Delafield, Village of Hartland, Village of Nashotah, Town of Delafield and Village of Summit. The Commission owns, maintains and operates five major pumping stations, one central wastewater treatment facility, which includes one of the five pumping stations, 42,858 feet of main interceptor sewers and about 21,120 feet of effluent sewer that ends in an aeration cascade.

RV Dump Site
The Delafield-Hartland Wastewater Treatment Plant operates an RV dump site located at 416 Butler Drive, Delafield.  The site is open all year long Monday through Friday from 7:00 am to 3:00 pm.  If you would like to use the site, stop at the main office building to pay the $5.00 dump station user fee and staff will escort you to the RV dump site.
