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

Before we compare the difference between the two, let’s highlight the one thing they have in common. Both the septic and cesspit tanks collect sewage and water waste from households and businesses that are not connected to the main sewer line.

A septic tank is buried deep underground and has two adjacent chambers. Both playing a vital role. As water waste enters into the first tank, this stores solids which have ran through the water. It then begins to decompose, and the water then runs into the second tank. This will eventually run through to a soakaway, river or stream. Your local water company will, likely every 3 or 6 months, remove the build-up of sludge within the first chamber of the septic tank. In summary, a septic tank is a simple and effective waste system.

A cesspit is a sealed underground tank system with the majority connected to a manhole cover which are adjacent to properties. The majority of cesspits are found at construction or camping sites.

These tend to be a holding or temporal tank as they are not connected to main sewer lines and need regular waste removal, ideally monthly depending on the level of the waste and size of the cesspit.

To summarise, a septic tank is effectively a filter system for rainfall which is linked to a soar away or river and requires regular cleaning to remove the build-up of waste. A cesspit is man-made waste pit which is set up temporarily or at a distance from a sewer system to collect man made waste.
