Preventative maintenance

Monitoring of performance

Documentation of findings


Servicing is a legal requirement. Since April 2010, the Environment Agency Environmental Permitting Programme (EPP2) requires that all sewage treatment plants are operated and maintained in accordance with the manufacturer’s instructions and that the maintenance log is recorded and retained for at least 5 years. The Environment Agency’s General Binding Rules state that that “Maintenance must be undertaken by someone who is competent”. WCI are British Water Accredited Service Engineers.

WCI has an in-depth understanding of how and why sewage treatment systems work. This means that when we service a system, we are not only carrying out the routine tasks recommended by the manufacturer of the system but we are also looking for reasons why the system might fail to operate correctly in the future.

WCI also has a comprehensive knowledge of the regulations that apply to the system we are servicing. This means that we take samples of the discharge from each system being serviced. Documentation of these findings maintain a record of compliance with the permits and standards that apply to the system. As such, we frequently are asked to performance manage systems that are failing to meet Environment Agency permit discharge criteria. Action include sampling and laboratory analysis, system process evaluation and rectification.

When a system does suffer a break-down or failure, WCI are on hand to fix it, quickly and efficiently. As WCI are renowned design and build wastewater contractors, if refurbishment, upgrading or replacement of the existing system is necessary, WCI can tender and carry out the work when instructed.
