A cesspit — sometimes called a holding tank — is a fully enclosed, sealed underground tank that collects all wastewater from a property with no outlet. Unlike a septic tank, nothing is discharged to the ground; the tank must be emptied regularly by a licensed waste carrier. Cesspits are typically chosen where a drainage field or soakaway is not feasible due to soil conditions, plot size, proximity to watercourses, or local planning restrictions.
Lancashire Septics Ltd supplies and installs cesspits and holding tanks for domestic and commercial properties throughout Preston, Blackpool, Lancaster, Blackburn, Chorley, and the surrounding Lancashire area. Our team carries out a full site survey before any work begins, assessing ground conditions, access, and the correct tank capacity for the number of occupants or the nature of the business.
We work with quality, manufacturer-approved tanks and handle all aspects of the installation: excavation, bedding, tank placement, inlet connections, and reinstatement. All work is carried out by experienced engineers and complies with current UK building regulations and Environment Agency guidelines. Once installed, we can also provide a regular emptying schedule to keep your cesspit compliant and problem-free.

- What is the difference between a cesspit and a septic tank?
- A cesspit is a sealed holding tank with no outlet — all waste is stored until it is pumped out by a licensed operator. A septic tank, by contrast, partially treats wastewater and discharges the liquid effluent to a drainage field. A cesspit is the correct solution where ground conditions or regulations prevent the use of a soakaway or drainage field.
- How often does a cesspit need to be emptied?
- This depends on tank size and the number of people using it, but most domestic cesspits require emptying every four to six weeks. Lancashire Septics Ltd can advise on the right capacity during your site survey and offer a regular emptying programme to suit your usage.
- Do I need planning permission to install a cesspit in Lancashire?
- Installation of a cesspit is generally considered permitted development, but you must comply with Building Regulations (Part H) and notify your local authority. In some cases — particularly near watercourses or in sensitive areas — additional consent may be required. We can advise you on the requirements specific to your site in Preston, Blackpool, Lancaster, Blackburn, or Chorley.
- What size cesspit do I need for my property?
- UK Building Regulations specify a minimum capacity of 18,000 litres for a two-bedroom property, with additional capacity required for each extra bedroom. Lancashire Septics Ltd sizes every installation to your specific property and usage during the initial site survey, ensuring the tank is compliant and practical for your needs.
