With an Orenco Sewer, raw sewage flows from a house or business to a watertight underground tank. Only the filtered liquid portion is discharged (by either pump or gravity) to shallow, small-diameter collection lines that follow the contour of the land.

The 7 Steps For How Septic Tank Systems Work Wastewater flows from the house into the septic tank. Anaerobic bacteria living inside it start breaking down some of the waste. Solid waste (inorganic material) sinks and liquid waste (oils, fats, grease) rises. The wastewater seeps into the drain field*

A septic tank typically holds waste long enough for solids to separate from the liquid and discharges that wastewater to a drainage field (called a leach field) or soil absorption field. That effluent water contains organic wastewater that will be discharged into the soil and fertilize it.

New aeration systems are required to run continuously. However, older aeration systems may be equipped with a timer. If the system is not causing a public health nuisance, it can continue operating as it was originally designed.

AdvanTex Control Systems A timer-controlled pump in the processing tank periodically doses effluent to a distribution system on top of the AdvanTex filter. Each time the filter is dosed, effluent percolates through the filter media and is treated by naturally occurring microorganisms that populate the filter.
