How many chambers?

A septic tank should have at least two chambers, 3 is better but 2 is enough. The second chamber can be around half the size of the first chamber.

In this tank the first chamber is 1.2m x 1.0m x 1.6m deep = 1.92 cubic metres liquid capacity. The second chamber is 0.6m x 1.0m x 1.6m deep = 0.96 cu m capacity = a total capacity of 2.88 cubic metres. Note that 1.6 metres is the depth of the effluent in the tank.

This tank is purposely designed to be quite deep while having a smaller footprint for use on smaller blocks of land.

Pumpings consist of removing sludge from the tank while inspections look into the functionality of the entire system.
