Pretreatment and the Homeowner in Cranberry Township

Homeowners can help the Township in its efforts to keep hazardous chemicals, grease, and other line-clogging material out of the wastewater treatment system. Please see the Prohibited Discharge section of Cranberry Township Ordinance No. 2006-373 for more information on what not be flushed or poured down any drain.

Each home has a sewer line which connects the house to the sanitary sewer system. This sewer line is called a "lateral" and it is the responsibility of the homeowner to keep the lateral in good working condition. Sewer line clogs caused by grease or "disposable" items such as paper towels or baby wipes can create a mess in your home and be expensive to unclog. If it moves farther into the system, it can cause problems for the neighborhood and increase maintenance costs at the treatment plant or pump stations.

Remember that what you flush, or pour down the drain may clog your pipes, and may also:

  • Create dangers to workers
  • Cause problems in the sewer system
  • Adversely impact the treatment facility
  • Cause harm to the environment
  • Ultimately jeopardize the welfare of the public
  • If you have questions on what may or may not be sent down the drain, please call 724-776-4806 x 1513.
