The Monroe Water Treatment Plant was originally built in 1967, near Lake Monroe. It was expanded in 2014 to a production rate of 30 million gallons per day, resulting in a capacity to meet the community's needs even during periods of peak demand. The purity of the drinking water produced by the Monroe WTP is rigorously monitored, and meets or exceeds all Federal and Indiana water quality standards.

With pumping initiated on September 9, 1967, MWTP is where Lake Monroe water becomes the drinking water for the more than 145,000 residents of Bloomington, IU, Monroe County, and beyond. It's the water that buoys Bloomington's industry, flows through our local food and drink establishments, irrigates produce, quenches fires, and washes hands at medical facilities. Bloomington would not be the city it is today without the smart decisions made decades ago to secure a reliable source of water.

In 2017, City of Bloomington Utilities celebrated the 50th Anniversary of the Monroe Water Treatment Plant!
