The Municipal Authority currently provides waste collection and treatment services for the City of McKeesport, White Oak Borough, Port Vue Borough, Liberty Borough, East McKeesport Borough, Elizabeth Township, Glassport Borough, Versailles Borough, and North Versailles Township, serving approximately 62,000 people.

Designed to process 11.5 million gallons per day, the Authority is the second largest sewage treatment plant in Allegheny County.

On January 1, 2009, the Authority acquired the McKeesport collection's system from the City of McKeesport. With over 100 miles of sewer lines and several hundred catch basins to maintain, the Authority created a new department consisting of a staff of 12 employees. This collection system department was assembled to service all of the Authority's properties, lines, and equipment located outside of the waste water treatment plant.

In conjunction with acquiring the sewer lines from the City, the Authority has also assumed the responsibility of providing the sewage billing and collection services for the residents of McKeesport and Versailles Borough.

In order to provide a working space for these two new departments, the former MAWC water billing office at 2800 Walnut Street in McKeesport was purchased. This location provides a convenient place for our rate payers to pay their bills or ask questions to a member of our billing staff.
