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

GRAF's Carat septic tanks are divided into two parts; the sewage is collected in the first part of the tank, the removable material and floating solids are trapped there so they can break down into sludge over time. The wastewater flows freely into the second part, and then out of the tank via the outlet and into a suitable drainage field.

Being made out of plastic, this tank is light weight, able to be installed in tricky local conditions without a crane and you can use granular backfill instead of concrete. This highly stable design also allows you to install the tank with the water table up to half way up!

To get an idea of the size of Carat tank suitable for your project, a simple calculation to get you started is to multiply 500 litres of capacity by the number of inhabitants at the dwelling. This capacity per person is based on an approximate volume of 150 litres per inhabitant per day, and as the wastewater would take roughly 3 days to pass through the system, the 150 litres is multiplied by 3 days and rounded up to be sure!
