Though the Northwest Water Commission was authorized by state legislation in 1957, it did not begin distributing water to its member communities until 1984. The member communities include the Village of Buffalo Grove, the Village of Palatine, the Village of Arlington Heights and the Village of Wheeling. The Commission is governed by a five-member Board of Directors. Each member agency has one appointment and there is one appointment by the Cook County Board of Commissioners. The current members include three Village Managers (Wheeling, Palatine and Buffalo Grove), one Public Works Director (Arlington Heights) and a former Village Manager and Finance Director (Cook County Board appointment). The NWC Board of Directors is a collegial group committed to charting a course for the Agency’s future that is in the best interest of the member agencies. In addition to providing water to the 285,000 residents of the four communities, the Agency recently signed a contract with the City of Des Plaines to supply up to 5 MGD of water to the City beginning on January 1, 2016. This represents approximately 70% of Des Plaines’ water consumption.

The NWC obtains its water from the City of Evanston. The NWC and the City of Evanston have a contract that ends in 20 years. The NWC represents 58% of the City of Evanston’s water system. The contract provides for a cap of 55 MGD on withdrawal with the average at 25 MGD and a peak that approaches 40 MGD.

The Northwest Water Commission is an agency independent of the Village of Buffalo Grove.  They have hired AECOM, a consulting engineering firm, to oversee the project.  John Spencer is the Resident Engineer and primary contact.  He can be reached at 773-447-1496 or
