HOW A EFFLUENT SEWER WORKS

With an effluent sewer, raw sewage flows from the house or business to a watertight underground concrete tank, where it is pretreated.  Only the filtered liquid is discharged (by either pump or gravity) through the service lines, to small diameter collection lines, that can be trenched in and follow the contour of the land and below the frost line.  Solids remain in the concrete tank, for passive, natural treatment.  Sludge in the tanks typically requires pumping only once every 7 to 10 years.

FRACTION OF THE COST OF CONVENTIONAL SEWERS

Effluent sewers dramatically reduce short-term and long-term wastewater treatment cost for communities and developers.  In fact, effluent sewers are often half the cost, or less, of conventional gravity sewers.

SAVE ON EQUIPMENT AND LABOUR

  • Collection lines are shallowly buried, just below the frost line, reducing excavation costs.
  • Inexpensive, small diameter collection lines are used.
  • Expensive manholes and lift stations are eliminated, in most cases.
  • Installation time is reduced by one-half or more, compared to coventional sewers.

 

SAVE ON OPERATION AND MAINTENANCE

  • Low maintenance has been documented with effluent sewers.
  • 24-hour back-up storage in on-lot concrete tanks reduces emergency calls and overtime costs.
  • Home owners pay less in energy costs for pumping
  • Residential tanks typically require pumping just once every 7 to 10 years
