What makes this feel less like a headache
Compliance kept front and centre
We install systems with safe discharge and current requirements in mind. That gives you a clearer path when a sale, upgrade, or replacement can't wait.
Groundworks and drainage together
We don't treat the excavation as an afterthought. Our groundwork and drainage knowledge helps the whole installation work as one system.
Right for homes and sites
We carry out installations for domestic properties and commercial premises. That means the solution is shaped around your wastewater demands, not forced into a one-size-fits-all setup.
A proper system for properties off the mains
Off mains sewage treatment installation starts with understanding what your site already has and what it now needs to meet current requirements. We assess existing arrangements, specify a suitable treatment plant, and plan the groundworks so Kwikfield Construction Ltd can install a system that works properly from day one. That matters if you're replacing an ageing septic tank, preparing for a property sale, or sorting a site where discharge needs to be safe and compliant. We excavate the tank position, prepare the base, install the unit, and connect the inlet and outlet pipework with care. The aim is simple: treated water that can discharge safely and a system that suits the way your property actually operates. We carry out this work for rural homes and commercial sites alike, because wastewater problems don't politely wait for a convenient time.


Groundworks that give the installation a fighting chance
Good installation work begins below ground, because a treatment plant is only as sound as the base it sits on and the drainage around it. Our team handles excavation, bed preparation, backfilling, and the linked pipe connections, with Kwikfield Construction Ltd coordinating each stage so nothing is left to guesswork. That joined-up approach helps avoid the kind of issues that show up later as poor flow, awkward access, or costly remedial work. We also match the system to the demands of your site, whether you're a homeowner moving on from a septic tank or a commercial client dealing with site wastewater. Based in Hailsham, we usually work across East Sussex and can travel further for larger jobs.
Frequently asked questions
What is involved in sewage treatment plant installation?
We start by assessing your current setup and the site conditions. We then specify a suitable plant, excavate the area, prepare the base, install the unit, and connect the inlet and outlet pipework so treated water can discharge safely.
When should a septic tank be replaced with a sewage treatment plant?
Replacement is often needed when an older system no longer meets current discharge rules, performs poorly, or becomes an issue during a property sale. A sewage treatment plant is designed to treat wastewater to a higher standard before it leaves your site.
Is this service suitable for commercial sites as well as homes?
Yes. We install treatment systems for rural homes, small commercial premises, and larger sites with off mains wastewater needs. The right plant depends on site layout, usage levels, and discharge requirements.
