Authority History

The Moon Township Municipal Authority (MTMA) was created in 1947. Township supervisors created the MTMA with the long-term goal of eventually owning and operating public water and wastewater systems in the area.

In the late 1940's, Allegheny County constructed a water pump station in Coraopolis with a few water lines in place primarily to bring treated water to the Greater Pittsburgh Airport. By 1951, the Township started to provide water service to residents through the use of the same Allegheny County system and Coraopolis supply. In 1957, MTMA took over this water system. Another MTMA landmark occurred in 1960 when the first wastewater project was undertaken to provide sanitary sewer service to a portion of the Township. By 1965, the Authority's Water Treatment facility became operational providing purified groundwater to Moon Township customers with a capacity of 3.5 million gallons per day (mgd). Subsequently, the facility increased its capacity to 5.18 million gallons per day with water supply coming from underground wells adjacent to the Ohio River. Due to growth and increased demand, in 2000 a surface water intake structure was constructed drawing raw water from the Ohio River. In addition, the Water Treatment Plant was upgraded to accommodate treatment of a blended water supply.

MTMA now supplies water to Moon Township, Pittsburgh International Airport, The U.S. Air Force Reserve and PA National Guard bases, and small portions of North Fayette and Findlay Townships.

Wastewater services have also grown since 1960. In 1974, MTMA's Montour Run Water Pollution Control Plant began operating with a permitted capacity to treat up to 2.5 million gallons of wastewater daily. By 1991, it was up to a 6.2 million gallon permitted capacity per day. Today the facility, renamed the Leonard L. Nary Wastewater Treatment Plant at Montour Run (see Montour Run Treatment Plant Renamed) treats wastewater from portions of Moon, Robinson, North Fayette and Findlay Townships, Pittsburgh International Airport, and the PA Air National Guard and U.S. Air Force Reserve bases. In 1994, the Authority added operation of the Flaugherty Run Wastewater Treatment Plant with an initial capacity to treat 1.0 million gallons of wastewater per day (mgd). In May 2006, the Flaugherty Plant expansion was completed increasing its capacity to 2.0 mgd.; it now allows for growth in both Moon Township, Crescent Township and South Heights Borough. The expansion provides for adequate facilities to replace the former Crescent South Heights Treatment Plant.

MTMA also has over 215 miles of sanitary sewer and over 145 miles of water main lines.

And, in 1990, the Moon Township Board of Supervisors provided the Moon Township Municipal Authority with the responsibility of solid waste and recyclable material collection.

Montour Run Treatment Plant Renamed

On July 20, 2005, the Moon Township Municipal Authority Board of Directors renamed the Montour Run Wastewater Treatment Plant the "Leonard L. Nary Wastewater Treatment Plant at Montour Run," in recognition of Mr. Nary's dedication to the community. Initially providing service to develop youth sports teams, Leonard Nary was Commissioner of the Moon Township Crescent Athletic Association for eight years and President of the Moon Township Board of Parks and Recreation for 12 years. Most notably, he served on the Board of Directors of the Moon Township Municipal Authority for 25 years.
