Which types of tanks need servicing?

Sewage treatment plants, pumping stations and grease management systems all need regular servicing.

Serious can schedule your maintenance visit alongside a tanker to ensure your systems are working at their best. To enquire about a service plan, send us your details and we will contact you with a quote.

What happens on a service visit?

It might seem vague, but every plant is different, so it all depends on the make and model of your tank as they all work slightly differently.

If you have any questions on your plant or one you are thinking of buying, just ask.

Why do plants need servicing?

Maintenance and servicing is vital for keeping things ticking over nicely. Without regular care, these are some of the problems you face:

  • Raw, untreated sewage raising up from your tank and spilling into local streams or ditches

  • Toilets, sinks and showers backing up or taking a long time to drain

  • Overflowing toilets or sinks

  • Full inspection chambers (these should usually be empty)

  • Boggy grass around the tank

  • Nasty smells

Let Serious take away the hard work with a service plan, send us your infomation and we will phone you to discuss.

How do I know if my sewage treatment plant isn't working?

If you look after your plant in line with the manufacturers recommendations and don't put anything down your toilets or sinks that you shouldn't, your sewage treatment plant should work effectively for a long time. 

Signs that your sewage treatment plant isn't working includes:

  • Bad smells

  • No noise coming from the plant or loud / unfamiliar noises

  • A white, filamentous growth over the treatment zone

  • Boggy areas around the tank

  • Floating sludge in the humus tank

  • No crust in the primary tank

The issues above could be caused by a number of factors and should be investigated by an engineer as soon as possible. If you are experiencing any of these problems, let us know
