Sanitary Sewer

Brush Creek Waste Water Pollution Control Plant

The sanitary sewer system is a key piece of infrastructure consisting of approximately 198.82 miles of sewer pipes and 3 lift stations. This intricate network exists to make sure that the wastewater that gets flushed every day from homes and businesses makes its way to the Brush Creek Waste Water Pollution Control Plant where it’s properly cleaned and treated before being recycled back into Brush Creek. 

How does it work?

The majority of the sanitary sewer system works on gravity. The wastewater flows into underground pipes at an elevated level from the private sanitary laterals that connect properties to the sewer, then it follows the downward direction of the pipe to its final destination at the treatment plant.

What is a pump station?

Due to Cranberry Township’s varied geographic area, it’s impossible to have a single pipe that flows continuously from the northeastern portions of the Township all the way to the treatment plant So instead of having one pipe, the sewage flows into a deep pit with pumps that “lift” the sewage to a higher elevation where it can start flowing downward again. These lift stations are a key component in keeping the sanitary sewer system in working order. If a lift station were to fail, sewage could fill the pump pit and overflow onto the ground, causing a potential environmental hazard.

What causes a sewer to “back up”?

Sewers are designed to have enough difference in level from beginning to end to keep sewage moving quickly. However, sometimes material gets caught in the pipe and blocks water flow.

Some typical blockages are:

  • Tree roots, which work their way into the sewer through joints where pipes connect.
  • Grease from cooking oils and foods can coagulate and form large masses that stick to pipe walls that can cause a blockage.
  • Debris like rags and toys from homes and businesses. Once a single piece gets stuck in the system, other pieces tend to pile up.
  • Broken lines caused by construction crews working near the line or by heavy equipment moving over it.
