Brush Creek Treatment Plant

June 2016: Please note - due to construction, we cannot accommodate plant tour requests.


The Treatment Plant, located along Brush Creek, provides wastewater treatment services to all of Cranberry Township, along with portions of Pine, Marshall and New Sewickley Townships. Currently, the plant processes 3.2 millions of gallons of water per day. That's enough water to fill the Cranberry Community Waterpark pool seven times.

The plant utilizes physical, chemical and biological processes to remove harmful pollution. Wastewater is collected from homes, businesses and industries, and after being treated, is released into Brush Creek.

Odor Control

Odor management is an ongoing process. We need your cooperation and assistance in solving an odor problem. If you notice odors coming from the sewage treatment plant on Powell Road, please let us know. It is very important that we maintain a record of odor complaints and document the circumstances surrounding them. Your input allows us to further troubleshoot and improve conditions.

The nature of these processes develops odors which, at times, can drift throughout the community. The Township utilizes many resources to minimize the impact of odors to the surrounding neighborhoods. For a detailed summary, view the Brush Creek Odor Management Plan:

Other items initiated since the completion of the plan:

January 2008.The Township installed a carbon polishing unit to further reduce odors at three of the major process sources at the plant.

September 2009. A heater was installed on the inlet to the carbon polishing unit to lower humidity and increase performance of the carbon absorption process.

Cranberry takes grand prize in wastewater technology competition 

Hach Company, a Colorado-based manufacturer of analytic instruments and reagents used in wastewater treatment plants, has announced the grand prize winners of its second annual ‘See the BIG Picture’ contest. The Brush Creek Wastewater Treatment Plant was one of two Grand Prize winners and awarded $50,000 in Hach equipment based on their video submission, “Hach to the Future,” which used a movie-themed story line as its staff professionals – playing themselves in the highly-charged drama – struggled to deal with forces that menaced its operation.

A History of the Brush Creek Treatment Plant

1960 Before the Municipal Sewer and Water Authority was formed in 1960 to manage Cranberry Township’s original sewage treatment plant in Fernway – Cranberry’s first major housing development – the wastewater from most Cranberry households drained into on-lot septic systems.

1972 But outside of Fernway, Cranberry’s population growth, marked by the construction of homes and apartment buildings on lots too small for traditional septic fields, continued. In response, the Authority began to build a municipal sewage collection network along with a new and larger treatment facility – one designed to serve residents throughout the Brush Creek watershed. That plant, built to treat 500,000 gallons a day, went on line in 1972.

1998 Following several major expansions and the eventual consolidation of the Sewer and Water Authority into the Township’s Public Works Department in 1998, the plant became positioned to serve Cranberry’s rapidly-growing businesses and residential community as well as portions of Marshall, Pine, and New Sewickley Townships.

On an average day, the plant treats 3.2 million gallons of wastewater, returning most of it to Brush Creek, where it eventually enters the Ohio River. A smaller share of that treated water is redirected to nearby Cranberry Highlands Golf Course, where it is used for irrigation.

2007 The design capacity of the Brush Creek plant today is 4.5 million gallons a day – enough to accommodate the growth projected over the next 10 years, when the Township’s population is expected to be in the range of 40,000.

Today  As a result, forestalling future expansions by preserving the capacity and extending the life of the Brush Creek plant has been a top priority for Township officials.
