Many commercial property owners confuse septic tanks with cesspits. Both are used to manage wastewater on sites that are not connected to a main sewage network, but they serve different purposes and require very different maintenance schedules. Knowing which system your business has is important, but knowing who maintains it is even more essential.
Our team at Grey-Water Drainage Solutions provides professional, environmentally responsible emptying and maintenance of septic tanks and cesspits across South-East London and Kent. For commercial clients, cesspit and septic tank services are often managed on a contractual basis, giving you peace of mind that your system is regularly serviced, emptied, and compliant with environmental regulations without you needing to schedule or supervise each visit.
Understanding Septic Tanks and Cesspits
Both systems store wastewater and sewage from toilets, sinks, and drains. They’re common in remote or rural commercial properties such as holiday parks, hotels, industrial estates, and agricultural sites where a connection to the public sewer network isn’t possible.
Septic tanks treat the wastewater within the tank. Natural bacteria break down solids and separate waste from water. The treated effluent is then filtered and safely dispersed into the ground via a drainage field or soakaway, leaving only sludge that needs professional periodic removal.
Cesspits (or cesspools) are sealed holding tanks with no outlet. They don’t process or filter waste at all. Once full, cesspit emptying must be undertaken by completely draining the container and transporting the waste to a licensed treatment facility.
Because cesspits fill up much faster, they require more frequent servicing. A typical commercial site might need several visits a month depending on usage, which makes a service contract with Grey-Water the simplest and most reliable solution.
Choosing the Right System for Your Site
The choice between a septic tank and a cesspit depends on the type of property, the volume of wastewater produced, and the suitability of the surrounding land for drainage.
If the ground conditions allow for soakaway or drainage, a septic tank is often more cost-effective long term.
If drainage isn’t possible due to ground composition or environmental restrictions, a cesspit provides a contained solution, although it does require more regular attention.
Before making any decisions, professional advice is essential. Grey-Water’s experienced team can help assess your system, advise on schedules for maintenance and septic tank pumping, and ensure all waste management practices meet current environmental standards.
