What makes this kind of project feel more manageable
End-to-end install coordination
We manage the job from site assessment through to commissioning, which means you're not chasing separate contractors for excavation, pipework, system placement, and finishing works. Our joined-up approach helps keep the programme clearer and the site better organised.
Compliance-led replacement work
When an old septic setup is no longer suitable, we focus on practical upgrades that support current discharge requirements and property sale preparation. You get work that's planned around what your site needs, not a one-size-fits-all answer.
Hailsham base with East Sussex reach
We are based in Hailsham and regularly travel across East Sussex, including Eastbourne, for surveys and specialist groundworks. That local reach matters on projects that need to return visits, staged excavation, and reliable scheduling over several days.
Specialist installation work that solves messy ground problems
Ground issues have a habit of turning into bigger headaches if they're left too long, especially when an ageing septic system starts failing or a property sale brings compliance questions to the surface. We carry out specialist installation and groundwork services for homes and commercial sites, helping you deal with sewage treatment upgrades, rainwater harvesting systems, and the drainage work that ties everything together. Our team travels from our Hailsham base to Eastbourne for surveys, installations, and the kind of multi-day projects that need proper planning rather than guesswork. We assess site constraints carefully, because the right solution depends on your ground conditions, layout, discharge arrangements, and how the system will be used day to day. Kwikfield Construction Ltd handles the practical side from excavation through to pipework, controls where needed, and final commissioning, so you're not left trying to coordinate several trades at once. That means you get a clearer route to a working system that protects your property, supports environmental responsibilities, and keeps your project moving.
What the installation process looks like on site
Our work starts with understanding what your site can realistically support, then we match that to the right treatment unit or below-ground tank size for the job. We carry out excavation, prepare the area, install inlet and outlet pipework, route filtration and overflow where required, and connect systems into drainage runs or soakaways when that suits the layout. If your existing foul or surface water drainage needs repairs or renewal, we can tackle that as part of the wider job instead of leaving weak points buried underground. Because we serve Eastbourne from Hailsham, Kwikfield Construction Ltd can return for staged works, coordinate longer install, and keep the project practical from first visit to reinstatement. We work on domestic and commercial projects with a steady focus on safe discharge compliance, especially where a replacement system is needed before a sale or after a failing setup has started causing trouble.
Frequently asked questions
When might you need a new sewage treatment plant installed?
You may need a replacement if your current septic system is failing, if discharge arrangements are no longer suitable, or if compliance issues come up during a property sale. We assess your site, explain the options clearly, and install a system that suits your property and the required discharge setup.
Can rainwater harvesting tanks be fitted below ground?
Yes, we install below-ground rainwater harvesting tanks with the excavation, pipework, filtration, and overflow routing needed for the system to work properly. We can also plan how the tank connects to garden use, irrigation, or other non-potable applications on your site.
Do you only handle the tank installation itself?
No, we also carry out the supporting drainage and groundworks that often make the whole project possible. That can include site preparation, foul and surface water runs, repairs, renewals, excavation, and reinstatement once the main installation is complete.
