Ausdrain Septic Leach Drains

Leach drains (or septic drain fields) are underground systems that disperse, treat, and filter wastewater (effluent) from septic tanks into the soil. They function by letting water seep through perforated pipes into surrounding gravel and soil, where microbes naturally break down contaminants. This process keeps the environment safe by removing pollutants before water rejoins the groundwater.

The Ausdrain EnviroModule2 leach drain system distributed by Civil and General Distributors has been approved by councils and regulatory authorities including the Department of Health in Western Australia. It has an infiltrative area of approximately 1.3 m2 per metre of length, provided that effluent enters through the top of the drain. Each length of drain has an additional infiltrative area of 0.36 m2 provided by the two end plates.

They are practical, cost-effective and easy to install.

The EnviroModules are lightweight, have an open structure providing high flow rates and are extremely robust.

Once assembled the EnviroModules are easily carried and lifted by hand into the trench. They are then placed end to end in a line and covered on the top, sides and ends with a recommended geotextile fabric.
