"Water has become a highly precious resource. 
There  are  some  places  where  a barrel of water costs more than a barrel of oil."
              -Lloyd Axworthy, Foreign Minister of Canada
  • The Water Reclamation Facility (WRF) is a modern Class III Activated Sludge Treatment Plant.
    • The Plant EPA NPDES Permit is .450 MGD.  
    • The Collection System has 126,288 LF of sewer lines.
      •     Lift Stations.
  • The WRF processes all wastewater in the Borough and operates around the clock effectively handling domestic sewage. 
    • Wastewater is transported through the collection system to the WRF
      • This includes sewage coming from public buildings and businesses as well as residential homes.
    • The wastewater is filtered, contaminates removed, processed and purified into clean water and then returned to the local waterways.
      • The WRF utilizes naturally occurring biological organisms to remove a portion of the wastewater contamination.
      • Examples of contaminates include:
        • human waste
        • garbage
        • household cleaning chemicals
        • Effluents that run or leak into the collection system due to events such as rain or mudslides 
  • The Borough's Licensed Operators monitor and manage the process of waste water treatment. 


  • There are lots of products that are used in the bathroom. 
  • Some of them are labeled “flushable” but, unfortunately, they are not. 
  • Sanitary Sewer lines are not designed to transport anything but toilet paper, water and human waste.
  • Do not use your toilet as a trash can, anything other than toliet paper can clog the sewage system’s lines and pumps, leading to breakdowns and sewage overflows. 
    • Sewage overflows often require expensive repairs and harm the health of our local waterways.
  • Never flush the following items:
    • Facial tissues
    • Paper towels
    • Baby wipes/hygiene wipes even if labeled flushable
    • All-purpose cleaning wipes
    • Diapers
    • Cigarette butts
    • Dryer sheets
    • Toilet bowl scrubbing pads
    • Cotton swabs
    • Feminine hygiene products
    • Cat litter
    • Fats, oils and grease from the kitchen
    • Food scraps from the kitchen
