A sewage treatment plant is a working machine with moving parts, and like a boiler it needs a routine service to stay reliable. Manufacturers require an annual service to keep warranties valid, and the General Binding Rules require your system to be maintained so its discharge stays within the standard it was designed to meet.

A neglected plant fails quietly. The blower stops, the bacteria die back, and the plant slowly turns into an undersized septic tank, discharging poorly treated effluent to a watercourse or drainage field. By the time there is a smell or a visible problem, the fix is often a repair bill rather than a service.

We service all common makes of domestic treatment plant across Shropshire. A service visit covers the mechanical checks, the biological health of the plant, and the state of the sludge, with a written record you can keep with your house documents.

What the service includes

  • Annual servicing of all major plant makes and models
  • Blower, diaphragm, motor and disc checks, with parts replaced as needed
  • Sludge level measurement and de-sludging when required
  • Effluent quality spot checks
  • Alarm and electrical checks
  • Written service report for your records and any future house sale

Servicing is part of staying compliant

The General Binding Rules require off-mains systems to be maintained in line with the manufacturer’s instructions. A file of service records is exactly what a buyer’s solicitor wants to see when you sell, and exactly what the Environment Agency wants to see if a discharge is ever questioned.

Empty intervals differ from septic tanks

Treatment plants still accumulate sludge and need periodic de-sludging, typically once a year for domestic plants. We can combine servicing and de-sludging so the plant is dealt with in one visit.

What you are servicing

A treatment plant has moving parts and an air supply. That is what makes its outflow clean enough to discharge, and what needs servicing to stay that way.

Septic tank compared with a sewage treatment plant A septic tank settles solids but does not treat the wastewater, so its outlet may only discharge to a drainage field and never directly to a stream or ditch. A sewage treatment plant adds an air blower, which lets bacteria break the waste down and produces a much cleaner effluent, so it may discharge to a watercourse as well as to a drainage field, subject to the general binding rules. SEPTIC TANK Separates solids. Does not treat the water. OUTLET MAY DISCHARGE TO A drainage field or soakaway Perforated pipe in gravel, soaking into the ground A stream, ditch or any watercourse Banned since 2020. This is what forces an upgrade. SEWAGE TREATMENT PLANT Adds air, so bacteria actually treat the water. AIR PUMP OUTLET MAY DISCHARGE TO A drainage field or soakaway Same as a septic tank, and often still the best option A stream, ditch or watercourse Allowed, if it meets the general binding rules
The difference that matters is the air pump. A septic tank only settles waste, so its outlet must soak into the ground through a drainage field. A treatment plant breaks the waste down, so its cleaner outflow may go to a watercourse as well. If your septic tank currently runs to a ditch or stream, it no longer complies and will need replacing or re-routing.

Frequently asked questions

How often should a treatment plant be serviced?

Annually for almost all domestic plants, in line with the manufacturer’s instructions. Plants under heavier use, such as holiday lets, may need six-monthly visits.

Can you service a plant you did not install?

Yes. We service all common makes regardless of who installed them, and we can take over the schedule for a plant that has missed a few years, starting with a thorough health check.

My plant has stopped working. Is that a service or a repair?

Call us either way. Blower failures are the most common fault and are usually a quick fix. If something bigger has gone wrong we will diagnose it, quote for the repair, and keep the plant safe in the meantime.
