Sewage Treatment Plant Installation in Essex

Treatment plants for properties without a practical mains sewer connection.

Drainage for properties off the mains sewer

For suitable properties where a mains sewer connection is unavailable or impractical, we install sewage treatment plants. The work covers site assessment, planning, excavation, tank and pipework installation and the connections that go with it.

A treatment plant is installed in the ground, so the site matters as much as the equipment. We look at ground levels, access and where the plant and its pipework can sensibly go before any digging starts.

We then excavate, set the tank, lay and connect the pipework and complete the associated drainage works, using the mini excavators and groundwork experience that the rest of our drainage and construction work relies on.

What's included

  • Site assessment and installation planning
  • Excavation and tank installation
  • Pipework and connections
  • Account taken of ground levels and access
  • Regulatory requirements considered

Is a treatment plant right for your property?

Sewage treatment plants suit properties where there is no mains sewer connection, or where connecting is not practical. Whether one is right for you depends on the site: ground levels, access, available space and the regulatory requirements that apply. We assess these before recommending an installation.

From our Romford base we install sewage treatment plants across Essex and London. The same team handles the excavation, tank installation, pipework and connections, so the whole job is in one place.

Amazing Service – Highly Recommended! I can’t thank the drainage team enough for their amazing work! I had a serious problem with my pipes, and everything was completely blocked. The team spent hours working hard to clear the blockage and sort out the problem. They were extremely professional, friendly, patient, and dedicated. Even though it was a difficult and time-consuming job, they didn’t give up and made sure everything was properly cleaned and working again. I was really impressed by their hard work, kindness, and positive attitude. They went above and beyond, and I truly appreciate all their effort. A massive thank you to the whole team! You are a credit to your company. I would highly recommend you to anyone who needs drainage services!

Fully recommend to anyone with plumbing issues as they genuinely care to provide a good service and check up on the situation after. Had Jake over to check my loft bathroom and main bathroom on separate occasions and sorted out the problem ASAP and told us the next best steps to reduce costs in the long run. They encouraged us to go with the most cost effective option even if it was not benefitting them directly (in this case our newly done bathroom was having issues which came under a warranty).

The team done a great job, I had 3 manholes to replace on my drive that were collapsing. They replaced with much better heavier duty ones.

Not going to lie these guys actually know their stuff, not some shady guys that’ll give you the run around that your landlord knows… Anyway they came out on the day in an emergency and even went beyond to check the root of the issue! Will be coming back to them as they’re no nonsense. Also they said ETA was 1-2 and they made it here at one, don’t usually leave reviews but they definitely deserved one
