How big a septic tank?

The first thing we need to know is how big the tank should be. There are several ways of working this out but if you go to the charts at this will allow you to decide the size you will need.

Let us say we need a tank of 2.9 cubic metres (the amount of effluent the tank will hold) this is typical for an average 2 bathroom house with 4 people living in it. Refer to the construction drawing below for a 2.88 cu m septic tank designed for a typical household.

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.

The walls and floor of the tank are 10 cms (4 inches) thick reinforced concrete providing sufficient strength to withstand water pressure and a reasonable amount of earth movement. The reinforcing steel is a mesh of 8 mm diameter reinforcing bars spaced 15 cms (6 inches) apart and built into a mesh box.

Regular Inspections

The key to a thriving septic system is upkeep. You need to maintain your septic tank through frequent pumpings and inspections. Pumpings consist of removing sludge from the tank while inspections look into the functionality of the entire system. Identifying issues early on can help you avoid extremely costly repairs in the long-run. Proper septic system maintenance can help prolong the life of your septic tank.
