Septic tanks are traditional, single chamber solutions for domestic sewage disposal, they are ideal for situations where access to mains sewer is not possible or practical.

Key Features of Clearwater Septic Tanks include:

  • Quick and easy to install.
  • Reduced excavation costs
  • Requires less soil disposal and less backfill
  • Made from GRP making it strong and durable
  • Light, watertight and chemically resistant
  • Robust and weatherproof

In this 71,000 litre Clearwater Large Septic Tank, the sewage is collected and retained, allowing it over time to be anaerobically digested, breaking the solids down into sludge. The excess effluent liquid then flows from the tank, via the outlet, and into a suitable drainage field system. Take a look at our article on ‘How to size a septic drainage field’ for more information on this.

Installation requirements are dependent on the specific site conditions, however, this tank will require a suitable concrete base and surround to be cast on site and a concrete cover slab to suit. See the installation guide provided with the tank for more details.


Please note: max inhabitants is indicative usage of 150 litres/per person/per day.
