Wastewater Collection and Pretreatment

Cranberry Township’s wastewater collection system and Brush Creek Wastewater Treatment Plant are designed to transport and treat domestic wastewater, or as it is commonly called, sewage.  

This is the water that goes down the drain from the sinks, showers, toilets, and laundry tubs in your house or from similar fixtures at commercial establishments.

Cranberry Township's Industrial Pretreatment program is designed to proactively protect the integrity of the wastewater. The Pretreatment program uses both educational outreach and discharge permits to effectively meet this goal.

To treat the waste, the wastewater treatment plant uses biological, physical, and chemical processes

  • Microorganisms (bugs decompose the waste)
  • Decomposed material is allowed to settle
  • Treated water is disinfected and discharged into Brush Creek

The wastewater treatment system plays a very important role in the community, and keeping it running properly is vital to the physical as well as economic health of Cranberry Township and its residents.

Although Cranberry Township is not currently federally mandated by US EPA, Cranberry Township has opted to be proactive and go beyond using basic general prohibitions. Therefore, Chapter 19  specifies criteria through which certain industries are asked to complete and Industrial User Survey and may be issued an Industrial Wastewater Discharge Permit.  

Discharge Permit These permits, for what are known as Significant Industrial Users, contain limitations on pollutant discharge as well as requirements on when, where, how, and how often the industry must monitor its discharge to show compliance with the limits. To meet the limits, industries must often “pre-treat” their wastewater prior to discharge into the collection system.  That is where the name “Pretreatment Program” comes from.  To determine whether a company will be issued a permit or not, inspections are conducted at existing facilities and questionnaires are distributed to new businesses to see what types of processes are or will be carried out in their buildings.  

To further monitor what is in the wastewater headed for the plant, the Township collects samples from the sewer system to pinpoint areas from which prohibited substances may originate, and to determine if other facilities may need to have a permit issued to them.

In addition to monitoring industrial users, the control of Fats, Oils, and Grease (FOG) and Inflow and Infiltration (I & I) are major undertakings of the Pretreatment Department.   (I & I) are major undertakings of the Pretreatment Department.
