FAQs

Cesspits & Cesspools questions

What is the difference between a cesspit and a septic tank?

A cesspit is a sealed tank that simply stores wastewater with no treatment or discharge, so it must be emptied by tanker. A septic tank treats and discharges to a drainage field. Cesspits usually cost far more to run.

How often does a cesspit need emptying?

It depends on size and household use, but many cesspits need emptying every few weeks to a couple of months. Correct sizing at installation is the main way to control this cost.
