Natural methods of treating contaminated waters and effluent streams have been well received by environmentally conscious clients and regulatory groups alike.

This is essentially a system whereby sewage and effluent is dispersed over beds of growing reeds which have been planted in suitably prepared beds or soils. Aerobic conditions are created in these systems by the roots of the reeds which allow for an improved distribution of oxygen and produce an acceptable effluent before it is released into the natural watercourse.

It is within this lined reed bed system that complex biological, physical and chemical reactions occur between the plants, the substrate and microbes which result in effluent purification.

The presence of the vegetation and reeds themselves is also conducive to the re-regeneration and re-stocking of Wild Fowl and in the development of bird sanctuaries as they closely resemble the environment of natural wetlands.

Smaller lined impoundments and lagoons are used for these projects which serve small communities / roadside service stations / sports camps / abattoirs and many more.

The liner is generally quite thick ( up to 2 or 2,5mm ) and is often protected on either side by a substantial geotextile. The liner system is then covered with a layer of gravel to meet the demands of the drainage design and thereafter by a further geotextile separator followed by the required type and depth of soil to accommodate the vegetation.

Typically, Linings which fall into this category can be divided , but certainly not limited to the following groups: Reed Beds / Artificial grasslands / Artificial wetlands.
