Septic Tank Construction

It is best to construct a single compartment for small capacity septic tanks. Larger capacities are the best fit for a two-compartment tank. The wall separating the two is about two-thirds the length away from the inlet. It, therefore, perform better than the single compartment tank. The two compartments interconnect above the sludge storage using pipes or square openings.

A concrete or plastic tank is the best to use. The floor and side walls are made using concrete and plastered to render a smooth surface. The floor has a slight slope of 10 per cent towards the sludge outlet. As a result, slung moves out more easily

The top cover of a septic tank is watertight and very thick. However, a manhole of relative size is created. This allows inspection and emptying of the tanks.

Maintenance of a septic Tank

Septic tanks should be pumped out every five years to keep the disposal system working properly. However, this may need to be done more often, for example, if they overflow or become blocked. The septic tank effluent should be well and carefully disposed of away so as to prevent any nuisance or danger to public health. This is because it has a foul smell and contains a substantial portion of dissolved organic matter and pathogenic organisms.

While making waste disposal,  an exhauster truck fetches the wastewater from the septic tank using hydraulic power. The track then carries it to land set aside for disposing and treating of the wastewater.

As a result, it can last up to 50 years of course with good use and maintenance.
