Rainwater Harvesting Systems

Re-using rainwater with a rainwater harvesting tank is good for the environment, a sustainable way of using water, and its money-saving. Rainwater harvesting tanks collect, filter and store rainwater so that the water can be used around a home, building and garden. Whilst the collected rainwater isn’t safe for human consumption, the water can be used as grey water for cleaning cars, watering plants, for flushing toilets and for washing clothes.

You simply connect a guttering downpipe to the rainwater harvesting tank to ensure you collect the maximum amount of water possible and an overflow siphon ensures the tank doesn’t burst. Rainwater harvesting tanks feature filters, so the water passes through to eliminate debris and leaves being passed through the system.

There are so many benefits of rainwater harvesting, mainly the environmental and cost benefits. It’s predicted that cost savings of up to 50% can be made on the average annual UK water bill. With rainwater harvesting tanks, compared to traditional water butts, there is filtering and the tanks are buried which means there’s no obtrusion or unattractive butts in the garden.

Our collection of rainwater harvesting equipment offers exceptional durability and value for money. Rainwater harvesting equipment is suitable for a wide range of applications, from household garden to professional projects. Browse our extensive collection below.

The benefits of rainwater harvesting

There are so many reasons why hordes of people are getting into rainwater harvesting, but for most it’s largely to do with reducing those ever-climbing water bills. By collecting rainfall from hard surfaces such as roofs or manmade hard surfaces above ground, users can repurpose the water for uses such as landscape irrigation, flushing toilets, cleaning their car and washing clothes. But it’s not all about the bills: done properly, rainwater harvesting can turn your garden into a haven of green lushness and also provide you with an alternative water supply during any water-usage restrictions. Although harvested rainwater isn’t fit for human consumption, it is estimated that harvesting rainfall can slash the average household’s water bill by up to 50% a year.
