Rainwater harvesting tank in Hailsham with proper sizing

Domestic and commercial installs. Above or below ground options. Drainage and groundworks handled in-house

What makes this easier for you from day one

Proper sizing from the start

We size the system around demand, roof area, and rainfall. That helps you avoid paying for storage you don't need or ending up short when demand rises.

Groundworks and drainage together

We handle the excavation and the supporting drainage work as one joined-up job. That means fewer moving parts and fewer chances for problems between trades.

Clear handover and upkeep advice

We show you how the system works before sign-off. You'll also know what to check, from filters to pumps, to keep water flow reliable.

A smarter way to store and use rainwater

We install rainwater harvesting tank systems that collect water from your roof, pass it through filtration, and store it for practical jobs around your property. With Kwikfield Construction Ltd involved from the start, you get a setup that suits how you actually use water, from garden irrigation to toilet flushing or wash-down areas. Good planning matters here, because the right tank size depends on your roof area, typical rainfall, and how much stored water you expect to use. Some sites have room for a neat above-ground unit, while others are better served by a below-ground tank that keeps the system out of sight. This can make a real difference if you're trying to cut mains water use or want more resilience during dry spells. We work on domestic and commercial installations, so the design is shaped around your property rather than forced into a one-size-fits-all answer.

What the installation process actually looks like

Before any digging starts, we assess the site to check access, ground conditions, pipe routes, and the best position for the tank. Kwikfield Construction Ltd then carries out the groundworks, forms the base, places the tank, connects gutters and downpipes, and fits the filters and supply pipework. We also plan safe overflow to a suitable outfall, which matters more than people think once heavy rain turns up. If the job links into wider drainage work, we can coordinate that at the same time to keep the whole system working properly. Once everything is backfilled and made good, we test the setup so you know it fills, overflows, and supplies water as it should.

Frequently asked questions

What can a rainwater harvesting tank supply?

A rainwater harvesting tank is usually used for non-potable tasks such as garden watering, toilet flushing, and vehicle or plant wash-down. The exact uses depend on your property layout, demand, and how the system is designed.

Should I choose an above-ground or below-ground tank?

That depends on the space available, how much water you want to store, site access, and the look you want around the property. Below-ground tanks save surface space, while above-ground units can be simpler where excavation access is limited.

What maintenance does a rainwater harvesting tank need?

Most systems need routine filter cleaning and occasional inspections to check pipework, overflow points, and any fitted pump. Keeping up with these checks helps maintain water quality and steady performance over time.
