Septic Tanks

What happens inside

  1. First Chamber
    Domestic sewage enters the primary settlement chamber, which permits settlement of heavier solids and surplus sludge storage. Here gross solids are allowed to settle out under gravity and are gradually broken down by anaerobic digestion. The lighter greases and fats float to the top, forming a scum layer, and the liquid (sewage effluent) flows into the second chamber.
  2. Second Chamber
    Here hydraulic displacement is utilized to draw effluent from the cleanest area of the primary chamber before being transferred to the soak-away system. This, together with a unique outlet baffle, prevents solids and greases from flowing out with the liquids and ensures only the cleanest possible effluent is transferred to the soak-away system.

Applications

Type of waste water:
Domestic sewage

Conditions:
Normal or sandy soil that will adequately absorb the effluent and will not result in effluent pondering on the surface or being transferred directly to ground water. As well as areas with a low water table and a relatively low population density.

Key differentiator

Yields cleaner water than standard septic tanks to reduce the potential for water and soil pollution.

Value proposition

  • The only SABS-certified septic tanks in Africa
  • Specifically designed to cope with stressors of severe underground conditions
  • Infiltration chambers are recommended as alternatives to a soak-away constructed
    from rubble or similar
  • Accommodates between 4 to 25 people
  • Available in modular units for increased capacity

Conservancy Tanks

What happens inside

Domestic wastewater is directed into the tank for temporary storage. Once full, the waste is pumped out and disposed of according to legislation. The watertight tank prevents possible contamination of the soil and groundwater.

Applications

Type of wastewater:
Domestic, commercial and industrial wastewater (including sewage, black water and grey water).

Conditions:
Clay or hard rock, or in areas with a high water table or risk of contamination to the ground water, as well as densely populated areas.

Key differentiator

Prevents possible contamination of the soil and ground water.

Value proposition

  • Simple to install, with minimum maintenance required
  • Ensures no contamination of ground water
  • Robust, durable and easy to handle
  • Accommodates between 4 to 25 people
  • Available in modular units for increased capacity
