On September 21, 2009, a CERTIFICATE OF AMENDMENT was granted to the Center Township Sanitary Authority whereby the name changed from The Center Township Sewer Authority to The Center Township Sanitary Authority under the ACT 22 of 2001, known as The Municipal Authority Act. See the History Timeline listed below.


Before the Municipal Sewer Authority was formed, The wastewater from most
Center Township households drained into on-lot septic systems.
As construction of new homes, apartments and businesses increased on
lots too small for traditional septic fields, the Authority began to build a
municipal sewage collection network along with a new and larger treatment
facility. The Elkhorn Treatment Plant built to treat 1,000,000 gallons per day
went on line in 1973.
As demands increased for treatment capacity, Moon Run Treatment Plant
was built. The Moon Run Plant built to treat 500,000 gallons per day
went on line in 1975.
As growth in the Township Continued, additional sewage capacity was
required. In 1993 the Elkhorn Plant underwent a major expansion to
2,000,000 gallons per day. Most of the cost for the plant upgrade was financed
through the issue of Sewer Revenue Bonds and Pennvest Loans.
The Center Township Sanitary Authority discontinued flow to the Moon
Run treatment Plant in 2002. The flows from the Moon Run Plant are
conveyed to the Elkhorn Treatment Plant.
As of 2014, The collection of sanitary sewage is served by approximately
seventy (70) miles of sewers in conjunction with nine (11) Lift Stations which are
necessary to provide pumping assistance to the sewer lines that do not drain
by gravity.
