Maintain Your Tank

Service Your Tank

Everyone who owns a septic tank or sewage treatment plant has a duty of care by law to look after it. Keeping your septic tank or sewage treatment system well maintained is the best way to ensure it continues to function safely and effectively. We service every type of septic tank and sewage treatment plant on the market.

Benefits of a Sewage Treatment Plant Service Plan

  • Free initial tank assessment
  • Compliance with the Environment Agency who can issue large fines for dysfunctional tanks
  • Prolongs components which would otherwise rot/rust/block
  • Hassle free – one phone call to us and we’ll do the rest
  • Prevents expensive emergency call outs
  • Emptying and servicing usually costs less annually than being on mains sewerage


For domestic tank owners we would recommend you call us to arrange a free visit to have a look at your tank then we can assess it’s current state then we can go from there.

Sewage Treatment Plant Service Cost

It depends on a few factors such as the condition of your tank, the make and model, how much sewage it treats, distance we have to travel and so on. The best thing to do is contact us and request a free site visit so that we can make an assessment. After that we can provide a detailed quote you for any of the levels of cover.


As a guide, for a small tank/plant in good condition that treats domestic sewage a service will cost in the region of £100-£150. Commercial applications usually range between £150 and £300. Please bear in mind that site visits need to be within a reasonable distance of our base.

We will make things as simple and easy for you as possible. We’re happy to answer all of your questions that you might have about your tank and the level of service. Following each visit we will send you a report of our findings together with an invoice for the service. Any minor faults found during the service visits will be fixed there and then. Should we pick up on any major faults, we will notify you and recommend a solution.
