For applications requiring simple septic holding and treatment, the Carat S without baffle is the perfect option.

Floating and removable material is extracted from domestic wastewater in mechanical septic tanks.

This is pure mechanical cleaning, for which you need 500 litres of capacity per inhabitant. If you assume a volume of 150 litres, the wastewater passes through the system in three days. These septic tanks must have a total volume of at least 2,000 litres. A 2,000 litre system is sufficient for four inhabitants, another 500 litres, must be incorporated for each additional inhabitant.

  • Option to install underneath a driveway when you upgrade to a trafficable lid
  • Low weight: can also be installed without a crane
  • Flexibility for installation: the telescopic lid can be tilted and gives you more freedom on where you can install to achieve the required fall
  • Low-cost installation: no concrete required to anchor the tanks
  • Low maintenance: maintenance or cleaning work can be performed through the shafts
