Replacing or upgrading your off-mains drainage system
If your septic tank, sewage treatment plant or drainage system is failing, outdated or non-compliant, we can work out what’s needed and deliver a practical long-term solution.
When your existing system needs more than a repair
Older off-mains drainage systems can stop performing properly for all sorts of reasons. Sometimes the problem is obvious; sometimes it only comes to light during a survey, building project or property sale.
Failing or damaged
Cracks, collapsed components, backing up or a drainage field that is no longer working as it should.
No longer compliant
The existing arrangement may not meet current Environment Agency or Building Control requirements.
Your needs have changed
Extensions, additional occupancy or a change of use can mean the existing system is no longer suitable.
Not sure whether your system is compliant?
The right answer starts with the site
Replacing a tank isn’t simply a case of swapping one product for another. The condition of the existing system, ground conditions, discharge route, available space and how the property is used all affect what will work.
We assess the whole arrangement and recommend the most appropriate solution — whether that means a new sewage treatment plant, septic tank and drainage field, pumping arrangement or another site-specific approach.
From assessment to reinstatement
01 Assess
We look at the existing system, the site and what the property needs.
02 Design & specify
We work out the right solution and deal with the technical detail before work starts.
03 Install
Our team carries out the works carefully, with the right equipment and site protection.
04 Reinstate & hand over
We complete the connections, reinstate the site and explain the new system.
Ongoing servicing and maintenance can then be handled by EnviroServ.
Planned carefully. Carried out considerately.
Replacing an older system can involve significant groundworks, but that doesn’t have to mean unnecessary disruption. We plan access, protect the site where needed and work towards a clean, properly reinstated finish.
