servicing FAQ's


Which types of tanks need servicing?

Sewage treatment plantsPump Stations and grease traps all need regular servicing. Serious can schedule your maintenance visit alongside a tanker to ensure your systems are working at their best. 

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.

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

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.
