Practical experience with treatment plant faults
Treatment plant problems are not always obvious from the outside. Worn mechanical parts, failing motors and electrical faults can affect how a system operates. Identifying the underlying cause is important before deciding which repair is needed.
I assess the fault, explain what needs attention and recommend a practical solution. Where suitable parts are available, many repairs can be completed during the initial visit.
The Environment Agency & The General Binding Rules Guidance on Regular Servicing
Most sewage treatment plants installed in England are subject to the Environment Agency’s General Binding Rules. These require systems to be operated and maintained in accordance with the manufacturer’s instructions. Regular servicing helps ensure your treatment plant continues to operate efficiently, maintains compliance with manufacturers servicing guidelines and can identify potential issues before they develop into more costly problems.

We service and maintain most leading makes of domestic and commercial sewage treatment plants, including Klargester, Kingspan, BioDisc, WPL, Marsh Industries, Clearwater, Tricel, Conder and many other systems.

What Happens During a Service
Professional servicing helps identify worn or failing components before they cause breakdowns, helping to keep your sewage treatment plant operating efficiently and in accordance with the manufacturer’s recommendations. Our experience allows us to spot issues that may not be obvious until they become a costly repair.

When should a treatment plant be checked?
Arrange an inspection if you notice:
- Unpleasant smells around the plant
- Unusual mechanical noises or vibration
- An alarm or electrical fault
- Poor-quality discharge
- A motor, blower or pump that has stopped working
- A system that appears to be running continuously or behaving differently
Early diagnosis can help identify a developing fault before it leads to a more extensive repair.

Frequently Asked Questions
Most domestic sewage treatment plants should be serviced at least once a year, although the recommended interval varies by manufacturer, model and usage. Regular servicing helps identify potential problems early and keeps your system operating efficiently. If you’re unsure when your plant is due for a service, get in touch and I can advise.
Common signs include unpleasant odours, unusual noises, warning alarms, slow drainage, poor-quality discharge or the system not operating as expected. If you notice any of these issues, it’s best to have the system inspected as soon as possible to help prevent more serious faults, potential pollution and costly repairs.
