Onsite Infiltration Systems (Septic & Drain Field)

Onsite Systems for recycling wastewater have become a sustainable long-term solution

A septic system is an onsite wastewater treatment system that processes and purifies household waste (effluent). The effluent consists of blackwater (toilet wastes) and greywater (kitchen sink, bathtub and laundry wastes).

A septic system has two components: a septic tank and a leachfield or drainfield. Primary treatment occurs in the septic tank, where bacteria digest organic materials in the wastewater. The effluent then flows into the leachfield for secondary treatment. Here, bacteria complete the digestion and purification process as the wastewater slowly leaches or infiltrates into the soil.

Onsite systems provide a passive reliable means of wastewater treatment at a relatively low cost, while preserving environmental quality. As the population density increases, regulators and public health officials responsible for water quality have emphasized the need for regulations based on sound science and real performance.
