What makes this kind of work feel more straightforward
End to end below ground works
We do more than dig a hole and drop in a tank. Our work covers investigation, excavation, placement, connections, backfill, and reinstatement, which gives you one coordinated process instead of a patchwork of separate jobs.
Domestic and commercial site experience
Some projects sit behind a family home. Others need a more structured approach on a commercial site. We work across both, which helps us plan access, timing, and installation stages in a practical way.
Useful for upgrade led projects
When an older drainage setup needs replacing, or a property sale depends on a more suitable arrangement, we carry out installation work with that real world pressure in mind. Our focus stays on getting the groundwork and system installation done properly for the site.
Below ground work that keeps a project moving
Groundworks are the part of a project you can't afford to get wrong. If drainage is outdated, a septic arrangement no longer suits the site, or a sale depends on bringing things up to standard, delays can pile up fast. We carry out practical below ground work across London, with a clear focus on sewage treatment plant installation, rainwater harvesting tank installation, drainage, and site preparation. Our work covers the full process, from ground investigation and excavation through to tank placement, pipe connections, backfilling, and reinstatement, so you're not left juggling separate trades. We take on domestic and commercial installations, and we plan site visits and work phases from our base at 30-34 North Street, Hailsham, BN27 1DW to keep each stage organised. At Kwikfield Construction Ltd, we handle projects within a typical operating range of around 50 to 360 miles, which includes London within our stated coverage area.
Planned installations with practical site coordination
Every site has its own layout under the surface, so we start by looking at what is already there and what the installation needs to achieve. We excavate for tanks, prepare bases, install connecting pipework, and coordinate foul or surface water drainage elements where the project calls for them. When you need treated effluent arrangements suitable for discharge where permitted, or a rainwater system for 'non' potable uses such as toilets or irrigation, we keep the work focused on the specification and the ground conditions. Projects in London often need careful scheduling, so we organise travel to site, planned visits, and installation phases in a way that helps reduce disruption to your property or premises. At Kwikfield Construction Ltd, we also carry out the supporting trenches, reinstatement, and general site prep that help the whole job run properly.
Frequently asked questions
What does a sewage treatment plant installation usually involve?
We usually begin with checking the site and ground conditions, then move on to excavation, preparing the base, placing the tank or plant, connecting pipework, backfilling, and reinstating the area. The exact setup depends on your site layout and the type of system being installed.
Can you install rainwater harvesting systems for homes and commercial premises in London?
Yes. We take on domestic and commercial rainwater harvesting tank installations in London. These systems are designed to collect, store, and reuse rainwater for 'non' potable purposes where specified, such as toilet flushing or irrigation.
Do you cover London even though you are based in Hailsham?
Yes. London is within our stated coverage area, and we work from our base at 30-34 North Street, Hailsham, BN27 1DW. We plan travel to site, scheduled visits, and the timing of groundwork and installation phases, so projects can be carried out efficiently.
