What is a community system l.jpg

What is a Community System?

  • Community Sewerage System (Ch 71.1 – Definitions)

    • Community Sewage System – “ a sewage facility, whether publicly or privately owned, for the collection of sewage from two or more lots or two or more equivalent dwelling units and the treatment or disposal or both of the sewage on one or more of the lots or at another site.

    • Options:

      • Community On-lot Sewage System (soil-based renovation approach or retention tank)

      • Community Sewerage System (non-soil based

        renovation approach)


Community on lot system l.jpg

Community On-Lot System

  • Conventional Systems

  • Seasonal Spray Irrigation

  • Drip Irrigation

Site Evaluations – Conducted

with Local Agency and PADEP


Conventional systems l.jpg

Conventional Systems

  • In-ground Seepage Beds and Trenches

  • Elevated Sand Mounds

  • Elevated Sand Trenches

  • Retaining Tanks – Holding Tanks, Privies, Chemical Toilet, Recycling Toilets, Incinerating and Composting Toilets. (temporary) – May be integrated into design of community systems, but typically are used on individual systems.


Conventional l.jpg

Conventional

  • Sand Mound System

    • Design using peak daily flow or design may be based on effluent quality, whichever more limiting.

    • Additional site characterization is required.

    • System may require 100 % reserve or backup.

    • May require additional pretreatment to remove nitrogen compounds or treat strong or complex organic wastes.

Pretreatment

Septic Tanks,

Grease Tanks, and Effluent Filters

Spray irrigation l.jpg

Spray Irrigation

  • For much of Northeastern Pennsylvania, a “SLOW Rate” spray irrigation

  • approach has been employed.

  • Seasonal Approach – Suitable Spray Season a function of the nature of

  • the development and use, meteorological conditions, soil conditions, and

  • local groundwater/geological conditions.

  • Prior to Irrigation, the wastewater is treated to secondary treatment

  • Standards. YES – THE WASTEWATER IS TREATED. Treatment – Package

  • Treatment System or Aerated Lagoon.

  • This is a Seasonal System – during the non-spray season the treated

  • effluent is stored, stream discharged, or disposed of in another manner.

  • In NEPA, the system has been used for seasonal developments (CAMPS),

  • housing projects, schools (East Stroudsburg), and commercial developments.

Drip irrigation potential year round disposal option l.jpg

Drip IrrigationPotential Year-Round Disposal Option

  • Hydraulic Loading Based on Soil Morphological Evaluation and Water Budget Analysis.

  • Depth to Limiting ZoneSHWT – 20 inches (6 inch installation depth)Bedrock – 26 inches (6 inch installation depth)

  • Common Installation Depth – 6 to 12 inches.

  • Slope up to 25 %.

  • Primary Treatment – Septic Tanks or Aerobic System.

  • Secondary Treatment for Septic Tank Effluent -Sand filtration system, Aerobic Tank, or Peat filters for anaerobic pretreatment.

  • Pump Tank to Manufacturers Manifold Filter Disc Filtration and

  • Distribution System.

  • For large volume systems – Pretreatment would likely be a package treatment system with a sand filter.

  • Multiple Drip Zones – Dosed to maintain unsaturated flow.
