AdvanTex® Treatment Systems

Orenco’s AdvanTex® Treatment Systems are an ideal solution for environmentally sustainable treatment of residential wastewater flows.   To date, Silvester Enterprises has installed over 400 of these systems in Alberta.

There is a standard AdvanTex Treatment System model for every site condition, design flow, and regulatory requirement.

AdvanTex Treatment Systems are particularly well suited for:

  •  small sites
  •  failing systems
  •  poor soils
  •  nitrogen reduction
  •  environmentally sensitive sites
  •  stringent treatment standards
  •  pretreatment of moderately high-strength waste

How it Works

In the patented* AdvanTex Treatment System, household sewage flows into the processing tank, where it separates into scum, sludge, and liquid effluent. Filtered effluent is dosed to the AdvanTex filter pod, where it trickles through sheets of a synthetic textile. There, naturally occurring microorganisms remove impurities from the effluent. After recirculating between the tank and the AdvanTex filter, the effluent is discharged to the soil via irrigation or a drainfield. The system’s pump runs only a few minutes an hour, using just a few cents worth of electricity a day. Because solids decompose in the tank, the tank requires pumping only every 8–12 years, under normal use. Using little energy, generating a minimum of sludge, and purifying wastewater for beneficial reuse, AdvanTex Systems are one of the most environmentally sustainable technologies for home wastewater treatment.

AdvanTex turns household wastewater into clear, odorless effluent you can reuse for subsurface irrigation or disperse to a drainfield  


At-Grade Discharge  An  At-Grade consists of distributional lateral pipes above virgin ground surface. The pressurized pipe is leveled and supported with pipe stands.  The pressurized lateral is then covered with a 24" shield.  The entire assembly is then covered with wood chip cover or leaf mold or peat moss. The width will vary between 3 and 6 feet depending on slope and terrain variables.
