We acknowledge that the water crises in South Africa
has fallen vulnerable and SINVAC has therefore
adopted the C.A.R.E Principle.

  • C – Conserve
  • A – Add
  • R – Recycle/Reuse

Basic Sanitation

Conservancy Tanks

  • A conservancy tank is a sealed tank that contains and stores sewage from premises and is required to be emptied on a regular basis.
  • There is no outlet on the system. Propper calculations are made to determine the size of the unit based on capita serviced and flow.
  • Sizes Rage from 1000l – 100 000l Storage Capacity. Larger Units are supplied on request.

Septic Tanks:

  • A septic tank consists of a tank in which breakdown of the sewage occurs and from where effluent is dispersed into the ground through a soak away or French drain.
  • This is the preferred method of disposal of domestic sewage in areas where there is no Municipal waterborne sewerage reticulation.
  • Soak away / French drains are required to further treat the effluent.
  • Sizes Rage from 1000l – 100 000l Storage Capacity. Larger Units are supplied on request.
