What makes this kind of project feel more manageable
One team for groundwork and installation
We handle the excavation, drainage preparation, and installation support in one coordinated job. That means you get a smoother process with fewer handovers and less chance of delays between trades.
Suitable for off-mains properties
We install sewage treatment systems for sites that are not connected to mains sewerage. Our approach helps you put the right infrastructure in place for everyday use and for compliance considerations when selling a property.
Planned from our Hailsham base
We travel from Hailsham to Crowborough for site visits and project planning, coordinating access, deliveries, and plant as needed. That practical planning helps keep below-ground work organised before the heavier stages begin.
Groundworks that support complex site installations
Ground conditions can make a straightforward project feel anything but simple, especially when your property in Crowborough isn't connected to mains sewerage or needs below-ground infrastructure planned properly from the start. We carry out practical groundwork services that support sewage treatment plant installation, rainwater harvesting tank installation, drainage alterations, and the excavation needed to get everything in place safely. Our work is shaped around what your site actually needs, so you're not left juggling separate contractors for excavation, drainage, and installation planning. We travel from our Hailsham base to Crowborough for site visits, helping you plan access, plant movement, deliveries, and the groundwork needed before installation begins. Kwikfield Construction Ltd works on both domestic and commercial projects, which means we understand the different pressures involved when you're improving a home, preparing a site, or dealing with compliance matters linked to a property sale. In Crowborough, that joined-up approach can save you time, reduce disruption, and give you a clearer route from first visit to finished groundworks.


Installed with drainage, compliance, and site preparation in mind
If your property is off mains drainage, we can install a compliant sewage treatment plant that suits the site and supports the practical requirements that often matter during ownership changes or future property sales. We also supply and install rainwater harvesting tanks for non-potable water storage, with groundwork and drainage considered as part of the same job rather than as an afterthought. Our excavation and drainage work helps prepare the area properly, which is vital when tanks, pipework, level, and access all need to work together. Because we serve Crowborough as part of our East Sussex coverage, we can plan visits from our Hailsham base and coordinate plant and deliveries in a way that keeps the job moving. Kwikfield Construction Ltd handles the enabling works as well as the installation itself, so you get a more organised project and fewer loose ends to chase.
Frequently asked questions
Can you install a sewage treatment plant for a property in Crowborough that is not connected to mains sewerage?
Yes. We install sewage treatment plants for domestic and commercial sites where mains sewerage is not available. We can assess the site, plan the required groundworks, and carry out the installation with drainage and excavation considered as part of the wider job.
What is a rainwater harvesting tank usually used for?
A rainwater harvesting tank collects and stores rainwater for non-potable use, depending on the setup and intended application. We install these systems as part of site groundworks, making sure the excavation, drainage connections, and tank placement work together properly.
Do you cover Crowborough from your Hailsham base?
Yes. We are based in Hailsham, BN27 1DW, and serve Crowborough as part of our East Sussex coverage area. We typically work within a 50-60 mile radius for suitable projects and can arrange site visits to plan the work.
