Unfortunately, even the best-maintained septic tanks and treatment plants fail and need replacing. Growing tree roots, old brickwork and shifting ground, for instance, can all cause irreparable damage to soakaways and pipework. If you move to an old or neglected rural property, you may have no choice but to fit a new system just to cope with modern life.

Time for a replacement?

Our engineers can specify the best treatment plant for you and advise on where to locate it.

In the past, people could go years without emptying their septic tanks. You can’t do that anymore. That’s because we now fill them up so fast with water from baths, washing machines and dishwashers. Not only that but the soaps, bleaches, detergents and cleaners we use stop sewage-eating bacteria from working. That means so solids and sludges don’t get broken down and build up to cause blockages.

2020 deadline – Important

If your septic tank discharges directly into a stream, ditch or river, you have to replace it or upgrade to a full sewage treatment plant by 1 January 2020. If you are selling a property with an old septic tank like this you will have to replace it before you can sell.

We can then carry out all the ground works as part of our complete septic tank installation service, liaising with the local council and other authorities to ensure your new system complies with building regulations and the Environment Agency’s new rules on the disposal of liquid waste and sewage.


“It was a bit of a shock having to replace the old septic tank with a treatment plant. So, thank you for taking care of everything and making the whole process as painless as possible.”
