Question

Will a sewage treatment tank create noise and smells?

Accepted Answer

It is recommended to place the sewage treatment plant at least fifteen metres away from any domestic premises to minimise the risk of noise pollution since sewage treatment tanks operate 24/7.

During operation, oxygenated water moves through the tank while air is pushed into the water through an air blower. The air blower operates either on a piston or a diaphragm and moves to-and-fro in rapid succession, and it is this operation that causes the noise.

To avoid bad smells developing from the sewage treatment tank, it is recommended to have it cleaned once or twice a year. Residue, blockages, or neglect cause bad smells to materialise over a period of time and signify a need for maintenance.
