City of New Berlin water diversion approval
- In 2009, the DNR approved a maximum diversion amount of 2.142 million gallons per day averaged over a calendar year for the City of New Berlin.
- The City will continue to return water to the Lake Michigan Basin via Milwaukee Metropolitan Sewerage District resulting in no net loss of water from the Great Lakes Basin.
- The approval was granted under the Great Lakes-St. Lawrence River Basin Water Resources Compact (Compact).
- The compact banned diversions of Great Lakes water with a few exceptions.
- One exception to the compact’s ban on diversions allows a “straddling community,” such as New Berlin, to apply for a diversion of Great Lakes water.
- Diversions allowed under this exception must be used solely for public water supply purposes in the community.
The DNR approved the City of New Berlin’s diversion application and water supply service area plan on May 21, 2009. The DNR approved the City of New Berlin's request for a revised water supply service area and diversion area expansion on Nov. 27, 2012.
