The Hanover Park Water Reclamation Plant (WRP) is one of seven wastewater treatment facilities owned and operated by the Metropolitan Water Reclamation District of Greater Chicago (MWRD). The MWRD is the wastewater treatment and stormwater management agency for the City of Chicago and 125 Cook County communities. We work every day to mitigate flooding and convert wastewater into valuable resources like clean water, phosphorus, biosolids and methane. 

If you live within our service area, the water that goes down your toilet, sinks and drains eventually comes to us to be cleaned. We treat wastewater from homes and businesses throughout our 883-square-mile service area in addition to stormwater from some communities. All of this wastewater and stormwater flows through local sewers into our interceptors before flowing to WRPs where we clean the water and recover resources using a combination of physical, biological, and sometimes chemical, treatment processes.

The MWRD provides this service for over 5 million people. Nearly 450 billion gallons of wastewater is treated by our seven facilities every year.

In service since 1963, the Hanover Park WRP serves residents in northwestern Cook and DuPage County communities, including Hanover Park, Bartlett, Schaumburg and Hoffman Estates. The Hanover Park WRP serves 56,532 people within an 11.2 mile area and cleans an average of 12 mgd, with the capacity to clean 22 million gallons per day. In 1969 the MWRD purchased the Fischer Farm (200 acres adjacent to the Hanover Park WRP) and built the Upper DuPage reservoir which holds approximately 75 million gallons of stormwater overflow. The farmland also includes 100 usable acres for growing corn and soybeans. All of the solids produced at the Hanover Park WRP are recycled as soil conditioner for the farm fields. The harvested corn and soybeans are used for feedstock, ethanol and biodiesel.
