Why Regular Servicing Matters

Regular servicing helps keep your sewage treatment plant operating efficiently and reduces the risk of unexpected breakdowns. It also allows worn or damaged components to be identified before they fail, helping to avoid more costly repairs and unnecessary disruption.

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.
