The water system of the Municipal Authority of Westmoreland County was developed over the past 60+ years through the strategic acquisition of established systems and planned water main line extensions to accommodate growth. The timeline identifies key system acquisitions and expansions.
As a result of these acquisitions, the service area as now comprised, extends approximately 25 miles from east to west and 40 miles from north to south, and incorporates over 2,200 miles of pipeline.
Since 1950, the Authority has relied on the following two sources of supply:
BEAVER RUN RESERVOIR
The Beaver Run Reservoir was constructed in 1952 and then enlarged in 1962. It has a present capacity of 11 billion gallons, and a safe yield of 45 million gallons of water per day.
THE YOUGHIOGHENY RIVER
The Youghiogheny River is the other principal source of supply, with a drainage area of 1,326 square miles and minimum flow of 213 million gallons of water per day.
The system is currently served by the following three modern treatment facilities:
INDIAN CREEK SUPPLY FILTRATION PLANT
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.
MCKEESPORT FILTRATION PLANT
The McKeesport Filtration Plant, located in the City of McKeesport, was completed in 1990 with a rated capacity of 10 million gallons per day. The McKeesport Plant draws its water supply from the Youghiogheny River and serves the Western portion of the MAWC service territory.
THE GEORGE R. SWEENEY WATER TREATMENT PLANT
The George R. Sweeney Water Treatment Plant is located at the Beaver Run Reservoir in Bell Township. This facility went on line in July 1997, and has a rated capacity of 24 million gallons per day. This facility serves the Northern portion of the MAWC service territory.
