Somerset Township Municipal Authority (STMA) was incorporated under the Municipality Authorities Act of 1945 on December 19,1970. The Authority was formed by the Township of Somerset situated in the County of Somerset in southwestern Pennsylvania. Somerset Township is comprised of a 64 square mile area which surrounds the Borough of Somerset. STMA was created for the purpose of constructing and operating a sewage collection system to serve the Township. The system became operational in April, 1976.
STMA is governed by a five-member Board appointed to staggering terms by the Township Supervisors. The original members were Joseph Messina, William Bender, John Betters, Kenneth Halverson and Angelo Antenucci.
STMA owns and operates three sewage treatment plants -- Wells Creek, SCI - Somerset, and Lavansville -- and four water systems -- Oakridge, Listie, Friedens, and Reading Mines/Stoystown. STMA also purchases sewage service from Somerset Borough for use by Township customers primarily in the Route 601 District area.
The annual budget for STMA is adopted each December for the following year. The 2022 budget is as follows:
Water Systems - $2,328,254
Sewer Systems - $1,343,686
Prison System - $852,250

In addition to serving Somerset Township residents, STMA provides water and/or sewer services to Brothersvalley Township, Jefferson Township, Quemahoning Township, Somerset Borough, and Stoystown Borough through cooperation agreements with each of those governing bodies.
