Timeline
From a reservoir to a regional system.
LTMA is appointed by, but operationally distinct from, the Ligonier Township Board of Supervisors. It is also separate from the Municipal Authority of Westmoreland County, which treats much of our sewage.
1950
Authority chartered
The Ligonier Township Municipal Authority is chartered on January 10, 1950, with an original board led by Chairman Robert J. Black.
1953
Reservoir construction begins
Engineered by Neilan Engineers of Somerset, PA, construction begins on a 17,000,000-gallon reservoir. Early treatment is disinfection of surface water.
1994
Slow sand filtration plant online
After the EPA Surface Water Treatment Rule takes effect, the Authority completes a slow sand filtration plant and builds a backup well in the State Game Lands.
1996
Waterford Waterworks transferred
The Township Supervisors transfer the Waterford Waterworks transmission mains, distribution lines, and well to LTMA.
2002
Sewer service consolidates
The Ligonier Township Sanitary Authority dissolves and its sewer collection facilities transfer to LTMA, serving Oakwood Hills and Park Plan north of Ligonier.
2012
