Septic tanks are a traditional, single chamber answer for domestic sewage disposal when it isn’t possible to connect to a mains sewer system. In this 71,000 litre Klargester Large Septic Tank, the sewage is collected and, over time, the solids are digested anaerobically. This breaks them down into sludge and the surplus effluent liquid leaves the tank via the outlet. To disperse the resultant liquid you will require a suitable drainage field system. Take a look at our article on How to size a septic drainage field for more information on this.

Key Features of Klargester Septic Tanks include:

  • Simple to install for reduced on-site installation time.
  • 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

When planning an installation, you must consider the conditions specific to your site. This tank will require an appropriate concrete surround and base that will need to be created on site, and you will also need 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.
