What is a Cesspit?

Overview

Nowadays, more and more UK households use septic tanks or sewage treatment plants to treat their sewage.

However, in the UK, cesspits can be fitted as a last resort for when the ground is unsuitable for the effluent to disperse, like any sites close to drinking water sources. Raw sewage could potentially be discharged directly into surface waters without being treated enough and thus pollute the surrounding environment.

How does a cesspit work?

A cesspit is a sealed, waterproof tank buried underground. It merely collects sewage without treating it in any way.

Cesspits only have one single utility hole cover for access by waste collection companies. They are usually either made out of fibreglass or brick. The only pipe is an exhaust, to allow the escape of gas which builds up in the pit as there is no other opening.

How much does a Cesspit cost?

You are required to keep your cesspit in good condition: you have to empty it, clean it and fix any leaks.

Nonetheless, with a cesspit, you are not obliged to pay waste disposal bills to the local water authority.

How to maintain a cesspit?

Cesspits require regular emptying by a licensed waste disposal company using vacuum tankers. Many companies offer this service by strictly following the current standards and regulations.

Depending on the size of the tank, the property and the number of occupants, the cesspit can fill up quickly and require regular emptying: either monthly, quarterly or annually.

As previously stated, many companies in the UK can regularly empty your septic tank or cesspit at a competitive price, thus reducing the risk of blocked drains or overflow. These teams of experts are fully equipped to empty septic units of any size, increasing the functionality of the pits and avoiding potential failure.

How to repair a cesspit?

As sewage is untreated inside the cesspit, any leak has to be sealed as soon as possible to avoid contamination. That is why you need to check the levels of your fluids regularly. If you notice a fluid drop, then your tank has a breach.

Once you have spotted a leak, your cesspit would require draining, cleaning and resealing.

If constructed from brick, your cesspit might require rendering, seal it with a waterproof paint or line it again with Glass Reinforced Plastic (GRP). If manufactured from GRP, the tank may only require a patch. If it has broken down, you may consider upgrading your unit and replacing it with a septic tank or packaged treatment plant.
