Keeping a sewage treatment plant serviced, maintained and running smoothly protects your home or business, your neighbours and the local environment.
At Andersons Waste Management we provide specialist servicing, desludging and repairs for domestic and small commercial treatment plants, carried out by an experienced, professional team who understand both the technical and regulatory side of off-mains wastewater systems.
What our sewage treatment plant service includes
Our standard service is thorough and carried out to manufacturers’ and regulatory guidance.
Typical visits include:
- A full visual inspection of the plant: Chamber covers and surrounding area to check for leaks, structural damage and correct venting.
- Mechanical and electrical checks: We examine pumps, floats, aerators and control panels, confirm correct operation and test any alarm systems.
- Desludging (emptying) of tanks: Safe removal of sludge by a registered waste carrier, with a Waste Transfer Note supplied for your records.
- Sampling/visual assessment: We check the treatment performance and spot early signs of solids washout or poor treatment.
- Service report and recommendations: We will provide a clear report after every visit, including any remedial work required, replacement parts suggested and guidance on day-to-day operation.
If we find a fault, our engineers are qualified to carry out many repairs on site, or we can quickly organise a return visit with the right parts and equipment to minimise disruption.
Why regular treatment plant servicing matters
Sewage treatment plants rely on biological and mechanical processes to protect watercourses and soakaways. If sludge is allowed to build up, the plant loses capacity and treatment quality declines, which increases the risk of pollution, blockages and costly breakdowns.
The Environment Agency’s general binding rules make clear that systems must be maintained and desludged before sludge exceeds the design capacity. Regular servicing preserves treatment performance and extends the lifespan of the equipment and keeps you on the right side of regulatory obligations.
Recommended servicing and emptying intervals
There is no one-size-fits-all timetable because frequency depends on system type, size, occupancy and usage.
However, established guidance and manufacturers commonly recommend:
- Annual professional inspection and desludging as a minimum for most domestic sewage treatment plants to prevent solids overload and maintain effluent quality. Follow the plant manufacturer’s instructions if they specify a different interval.
- Septic tanks are typically desludged every 1–5 years depending on household size and tank capacity, while cesspits, which store rather than treat sewage, require much more frequent emptying, often every few weeks to months depending on use. These intervals should be confirmed by an on-site assessment.
- Additional checks after unusual events such as flooding, heavy use during a festival or extended houseguests, or if you notice odours, slow drainage or discoloured/solid effluent, these signs mean you should arrange a service without delay.
We always base our recommendations on the plant manufacturer’s instructions and regulatory guidance, and we log your system’s service history, so future visits are correctly tailored.
Health, safety and environmental compliance
Working with sewage is a specialist task that carries health and safety risks, so our engineers follow HSE guidance and safe working practices at all times.
We use appropriate personal protective equipment, confined-space precautions where needed, and only transport waste with registered carriers so sludge is disposed of legally and responsibly. You will receive documentation after every service to show legal disposal and compliance.
