What makes the job feel more manageable
End to end tank installations
We take care of the full sequence of work, from the first look at the site through to excavation, installation, connections, backfill, and making good. That means you're not left trying to coordinate separate trades for the groundworks and the tank system.
Practical East Sussex coverage
Our base in Hailsham gives us a sensible working reach across East Sussex, including Newhaven. We arrive prepared for excavation, drainage runs, and tank placement, which helps keep the work organised from the start.
Domestic and commercial capability
Some jobs are tied to property sales, some are part of upgrades, and others support new installations on sites without mains sewerage. We work across domestic and commercial settings, so you get an approach that matches the scope of your project rather than a guesswork solution.
Groundworks that solve the messy jobs properly
Drainage trouble, off mains wastewater needs, or a site that simply isn't ready for installation work can turn into a real headache fast. We carry out practical groundworks and specialist tank installations for domestic and commercial properties, with Newhaven firmly within the East Sussex area we regularly cover from our Hailsham base. When you need a sewage treatment plant for a property sale, an upgrade to an older setup, or the groundwork needed for a new drainage run, we focus on getting the job planned clearly and carried out properly. At Kwikfield Construction Ltd, we handle the kind of work that needs digging, heavy kit, sound judgement, and no fuss. We understand that you want the ground opened up, the system installed, and the site left in good order without confusion or hold ups. That's why we keep the process straightforward, explain what's happening on site, and make sure your project in Newhaven moves forward with a contractor that knows East Sussex ground conditions and access demands.


From excavation to final connections
Sewage treatment plant installation calls for more than dropping a tank in a hole, and we manage the job from site assessment through excavation, groundworks, tank placement, drainage connections, backfilling, and making good. We also install rainwater harvesting tanks that help you collect and reuse water for jobs such as garden irrigation and other non-potable supply, with careful attention to tank sizing, filtration, and future maintenance access. Our drainage work covers new runs and practical problem-solving around surface water and foul drainage, along with the trenching and reinstatement needed to support the full system. For Newhaven projects, we travel from Hailsham with the equipment required for excavation and installation, so you're dealing with one contractor that can take care of the groundwork as well as the specialist elements. Kwikfield Construction Ltd works on both domestic and commercial jobs, and we shape the approach around your site layout, access, and the demands of the installation rather than forcing one size fits all fix.
Frequently asked questions
Can you install a sewage treatment plant for a property that is not connected to mains sewerage?
Yes, we can assess the site and carry out the groundworks and installation needed for a sewage treatment plant where a property relies on its own wastewater system. We handle excavation, tank placement, connections, and reinstatement as part of the job.
What is involved in a rainwater harvesting tank installation?
We install the tank itself and complete the associated excavation, groundworks, and drainage connections needed for the system to work properly. We also consider practical points such as tank size, filtration, and safe access for future maintenance.
Do you cover Newhaven for drainage and groundwork projects?
Yes, we do. We are based in Hailsham and regularly travel across East Sussex, including Newhaven, for domestic and commercial drainage, groundwork, and specialist tank installation projects.
