/Definition
What is a Cesspit?
A cesspit, sometimes called a cesspool, is a sealed underground tank that collects and stores all wastewater and sewage from a property. Unlike septic tanks or sewage treatment plants, a cesspit doesn’t process or treat waste — it simply holds it securely until emptied by a licensed waste carrier.
Cesspit installations are typically chosen when off-mains drainage alternatives aren’t viable, such as:
- Areas with poor soil percolation or high groundwater
- Locations near watercourses with strict discharge regulations
- Sites with limited space or environmental restrictions
- Temporary or seasonal sites (e.g. event venues or mobile home parks)

Our Cesspit Installation Services
Cesspit Installation
- We provide complete cesspit installation services across Kent, Sussex, and Surrey, managing everything from excavation to connection. Every installation is tailored to your property’s ground conditions, tank size, and access needs.
- Groundworks and excavation
- Tank positioning & pipe connections
- Backfill and site reinstatement

Cesspit Replacement
- If your existing cesspit is damaged, leaking, or undersized, our team offers professional cesspit replacement services. We safely remove the old system and install a new, regulation-compliant tank. In some cases, we may also recommend upgrading to a septic tank or sewage treatment plant if it offers a more efficient long-term solution for your property.
/Planning
When is a Cesspit the Right Choice?
Cesspit installation is the best choice where no other form of off-mains drainage is feasible. They are ideal for:
- Small plots with insufficient ground for a soakaway
- Sites near watercourses with strict discharge rules
- Temporary installations for mobile homes or construction
- Properties with unpredictable or low usage (e.g. holiday lets)
While not the most cost-efficient long-term option due to emptying requirements, they are reliable, space-saving, and legally compliant when properly maintained.
Our cesspit installations have supported:
- Woodland cabins and lodges
- Rural event venues
- Static caravan sites
- Residential buildings awaiting sewer connection
