  The Indian Creek Supply Filtration Plant, located near the City of Connellsville, has a rated capacity of 45 million gallons per day and draws its water supply from both Indian Creek and the Youghiogheny River and serves the Southern portion of the MAWC service territory. This facility was constructed in 1973 and was upgraded in 1979.
