The Villages of Morton Grove and Niles (MGN) had purchased their water from the City of Chicago for over 100 years. In 2017, frustrated with continually rising rates, they decided to switch their water supplies to the City of Evanston. Savings over the life of the 40-year contract could soar as high as $100 million. 

After a study was conducted and a route chosen, the MGN Water Commission was formed. The Commission hired ATI as part of a team in June 2017 to design the numerous distribution and storage improvements necessary to make the conversion. The project was completed before the Village contracts with the City of Chicago expired in December 2018.
