Conventional septic systems

Conventional septic systems consist of two components; the septic tank, and the soakage trench.

How does a septic system work?

The tank of a septic system is installed in the ground with an access shaft over the lid opening to allow access to the tank for the purposes of maintenance and pumping out.

Septic tanks are required to be pumped out at least every 4 years

If the tank is not pumped out regularly then solids build up and begin to migrate to the soakage trench and the system will fail to operate efficiently.

Once the efficiency of the soakage trench is compromised the effluent may break through to surface level and create overflows and pose a health hazard.
