Sewage Treatment Plant Repair

Is your sewage treatment plant in need of repair?

It’s important to keep your eyes (and nose!) peeled for any potential problems with your sewage treatment plant.

You might notice the tank overflowing in your garden, with dirty water pooling above ground. Or your toilets take longer to flush than usual. Maybe the tank seems to have filled up again even though you’ve only recently had it emptied. Whatever the signs, if you have a problem with your sewage treatment plant, it’s best to find out what’s causing it as soon as possible.

Hopefully, the problem can be sorted out quickly by getting the tank emptied. It might even be that there is a blockage in the pipe running from your property to the tank itself.

If emptying the tank doesn’t solve the problem, it’s possible that the sewage treatment plant might be in need of repair. Sewage treatment plants can become damaged in a number of ways, for example:

  • Pressure from the water in the ground can be quite intense, especially after a period of really heavy rainfall. In fact, it can be so intense that it can actually push the sewage treatment plant up and out of the ground!

This can be a really urgent problem, because often this can shear the pipe connecting your property to the tank right off, meaning that the waste water from your property has nowhere to go. Call our team today on 0800 028 9903 and we can provide urgent advice and assistance.

  • Localised ground movement, which may not be obvious above ground, can also put a lot of pressure on the walls of a sewage treatment plant. This can cause fractures or splits to appear in the tank, which can let both waste water out of the tank and ground water in.
  • Roots from local trees or shrubs can cause damage to the walls of the sewage treatment plant, or to the soakaway system which the tank might connect to.

What’s the difference between a sewage treatment plant and a septic tank?

Sewage treatment plants provide a greater level of treatment to the waste water from your property than other drainage systems such as a septic tank. As a result, the waste water that leaves the sewage treatment plant is cleaner and more environmentally friendly. This also means that you can usually discharge the waste water produced by the treatment plant to a local watercourse (it is no longer legal to do the same with a septic tank).

A sewage treatment plant will either discharge through a sealed pipe, straight to a watercourse or ditch, or it will go to a soakaway system or drainage field. This is a system of perforated or slotted pipes which enable the waste water to percolate safely through the particles of the subsoils, without causing any pollution.

Below is a diagram of a septic tank and also one of a sewage treatment plant, so that you can see some of the differences between the two:
