Where one is not linked to municipal services Compact Sewage Treatment Plants and Septic Tanks are the solution.


Effluent is naturally biodegraded. With the assistance of proper design, final effluent meeting legislated standards is released back into the environment.

We also offer sequential batch reactor (SBR) technology. SBR's are industrial processing tanks for the treatment of wastewater. SBR reactors treat waste water such as sewage or output from anaerobic digesters in batches. Oxygen is bubbled through the waste water to reduce biological oxygen demand (BOD) and chemical oxygen demand (COD) to make suitable for discharge into sewers or for use on land. While there are several configurations of SBR’s the basic process is similar. The installation consists of at least two identically equipped tanks with a common inlet, which can be switched between them. The tanks have a “flow through” system, with raw wastewater (influent) coming in at one end and treated water (effluent) flowing out the other. While one tank is in settle/decant mode the other is aerating and filling. The final treated water is disinfected with inline UV exposure or Ozonation. 


Over a period of time the primary chamber starts getting an anaerobic and aerobic sludge build-up, which reduces the treatment capacity thereby lowering the biological retention time required. Fats, grease and oil discharge does not have natural bacteria to biodegrade them thus further aggravating the problem.


Solids, fats, oil and grease flow into the secondary chamber and ultimately into the soakaway, which starts congesting the soil and prevents percolation and ponding occurs. When the anaerobic treatment period reduces, waterborne diseases are not killed off and enter into the water source, aquifer, rivers and dams contaminating the water. During the rainy season the water table rises and the water commingles with the sewage in the soakaway further spreading waterborne diseases ultimately rendering them a health hazard to the community.

  • Septic system is under capacity/overloaded

  • Insufficient biological activity to break down the incoming effluent

  • An anaerobic and aerobic sludge build up begins to develop

  • The solid effluent builds up in the Primary  and Secondary Chamber reducing the capacity of the tank this reduces the retention time in the tank (time required to break down the suspended solids)

  • Fats and Gels begin to accumulate in the French Drain reducing the capability of the liquid to percolate into the ground

  • The liquid effluent  builds up and pooling appears on the surface of the ground

  • There will be a malodorous odour present
