System Maintenance
Did you know that your local authority has the power to force you to maintain your sewage treatment plant? In certain circumstances, the local authority can insist you carry out repairs or they do the work themselves and then charge you for it.

They can only do this if they deem that your system is causing a risk to public health or is a nuisance, for example if it is leaking or overflowing. It’s very unlikely of course but it does give a strong indication as to how important it is to maintain and service your treatment plant.

Don’t worry though, if you don’t currently get your system maintained then we can help you.
