Sewage Treatment Plant & Drainage Installations
Whether you’re installing a new off-mains drainage system, replacing an ageing septic tank or dealing with a failed drainage field, getting the installation right is essential.
Boxall Ward specialises in sewage treatment plant installation, septic tank replacement, drainage fields and associated groundworks throughout Sussex, Surrey, Kent, Hampshire and the wider South East.
With more than 20 years of experience in off-mains drainage, we can help with everything from assessing an existing system to designing, supplying and installing a suitable replacement.
Sewage Treatment Plant Installation
A modern sewage treatment plant can provide an effective solution for properties that aren’t connected to the mains sewer. Choosing the right system depends on the property, its wastewater requirements, ground conditions and available discharge arrangements.
Boxall Ward supplies and installs private sewage treatment systems for domestic and commercial properties. Our work includes new installations, replacement plants and the excavation and pipework required to connect the system.
We are also distributors of Matrix sewage treatment plants, with experience installing these systems in a range of situations.
Septic Tank Replacement
Older septic tanks can become damaged, fail to operate effectively or have discharge arrangements that no longer meet environmental requirements.
Where an existing installation needs replacing, we can assess the situation and advise on appropriate options. Depending on the property, this might involve a replacement septic tank and drainage field, a modern sewage treatment plant or alterations to the existing drainage arrangements.
We can also help where an existing system has been identified as unsuitable or potentially non-compliant following an off-mains drainage compliance check.
Drainage Field Installation & Replacement
A drainage field allows wastewater effluent to disperse into suitable ground through a network of underground pipework. Its design and installation are important to the performance of the whole drainage system.
We carry out drainage field installations and replacements, including the excavation, pipework and associated groundworks.
Where an existing drainage field has failed, we can investigate the problem and discuss whether replacement or other drainage alterations are appropriate.
For an example of our work, see our drainage field installation in Droxford, Hampshire.
Groundworks & Land Drainage
Installing an off-mains drainage system often involves considerably more than placing a tank in the ground. Excavation, trenching, connecting pipework and making good afterwards are all important parts of a properly completed project.
Our experience also extends to land drainage, where excess surface or groundwater can leave lawns, gardens, fields and other areas waterlogged.
Depending on the site and the problem, our work can include:
- Excavation and preparation for sewage treatment plants and septic tanks
- Drainage field installation and replacement
- Underground drainage pipework and trenching
- Land drainage pipes and ditching
- Culvert installation and replacement
- Associated groundworks and reinstatement
We understand the importance of carrying out these works carefully, particularly around established gardens, driveways and occupied properties.

Collapsed Culvert Replacement
A collapsed 500mm culvert running through numerous back gardens has now been replaced with a new pipe. This will stop many gardens flooding in the wet periods.
