What’s the Difference Between Cesspits and Septic Tanks?

Cesspits and septic tanks are commonly found in rural properties where the opportunity to connect to a main sewer system is not available. If you require a drainage system because there’s no way you can attach to mains sewer line, choosing a system that is right for you can be a challenge. How do you know whether a septic tank or a cesspit is the right choice for you?

Both septic tanks and cesspits are private systems and collect waste water and sewage from your property or business and they have many similarities. However, there are some stark differences between these two systems and which is best depends significantly on what you require.

How Do Septic Tanks Work?

Septic tanks use a simple treatment process which allows treated wastewater to drain away into a soakaway (a hole in the ground filled with rubble and coarse stones). The soakaway then disperses water back into the surrounding ground without flooding your garden.

A septic tank has two separate chambers: wastewater enters the first tank and the solids settle at the bottom, while liquids flow through into the second chamber. This system allows for any smaller suspended solids to settle in the tank and the water to exit the tank through the soakaway.

How Do Cesspits Work?

Cesspits do the messy work for you of collecting and storing the wastewater and sewage that comes from your property before it can be taken away to be treated. A common misconception is that cesspits treat the sewage from your property, but this is in fact not the case. Instead, they simply collect and store all the sewage before it can be taken away to be treated.

Your cesspit is a sealed unit that will fill up with sewage and eventually it will require emptying. The regularity of cesspit emptying depends significantly on the size of your property and the number of occupants. The more people your cesspit serves, the more frequently it will need emptying.

How Often is Emptying Required?

Septic tanks: septic tanks work efficiently to build up a collection of sewage until the system is full. Once full, it is important the sewage is only to be emptied and removed by a licensed professional. The regularity of septic tank emptying depends significantly on the size of your property and the number of people living in your home. The more space and the more people, the more frequently your septic tank will need emptying.

Cesspits: Cesspits do not have an extra outlet built-in and, therefore, all the sewage that goes into a cesspit has to be professionally removed and transported away to a proper treatment facility. Cesspit emptying is required at least twice a year but, again, frequency depends on the size of the tank, the level of occupancy, and the size of the property.

What are the Maintenance Requirements?

Cesspit Maintenance: Cesspit maintenance requires regular emptying to ensure the cesspit is able to work to its full efficiency. You must also ensure that the area surrounding the manhole is clear from any debris or materials so that access is easy for anyone coming to maintain or empty the system. If you neglect maintaining your cesspit and the tank becomes overly full, you will be in offence of the 1936 Public Health Law and must have your cesspit emptied by a professional as soon as possible.

Septic Tank Maintenance: Septic tanks can be maintained through being pumped out at least once a year. Pumping out your septic tank and having it emptied regularly ensures it is able to work effectively and reduces the likelihood of blockages or any other serious problems. If you notice any faults with the system or anything that looks problematic, it is important you call a professional to carry out repairs right away.

Where are Cesspits and Septic Tanks Located?

Cesspits: Many people find that cesspits can be quite an eyesore on their property grounds, which is why all the cesspits we sell are installed underground. Not only does this keep your garden clear but is also doesn’t take up any unnecessary space. Another benefit of cesspits being buried underground is that all the waste pipes from your property are underground anyway and are able, more easily, to feed through to the cesspit. What’s more, despite being buried underground your cesspit will be accessible via a manhole so that qualified professionals can empty the sewage with ease.

Septic Tanks: Septic tanks are installed in your property to be as inconspicuous as possible. Buried underground, septic tanks are installed at least 25 feet from your property and accessed through a manhole cover, so they can be emptied by qualified professionals.

What are the Benefits:

Septic Tanks: provide simple, safe, and effective onsite wastewater treatment. Septic tanks treat sewage naturally by allowing the water to seep into the ground, helping keep moisture on site which helps plants to grow and your garden to stay healthy. Septic tanks also significantly lessen the likelihood of raw sewage discharge from a sewage treatment plant. If properly installed and maintained, septic tanks provide a number of environmental benefits and can also help manage the waste from your property hygienically.

Cesspits: One of the main benefits of cesspits is that they require less frequent emptying than septic tanks. They also collect faecal matter in a closed tank which significantly reduces the spreading of pathogens.
