Rainwater Harvesting
Rainwater harvesting is the process of collecting, storing and then using rainwater as an alternative or complementary source to mains water. Harvested rainwater is commonly used for watering plants and flowers, washing cars, flushing toilets and washing clothes - helping you to save money and re-use our planet's most valuable natural resource.
In its simplest form, a garden water butt is a complete domestic rainwater harvesting system, capturing and storing rainwater ready to be used in a domestic garden. Accessories such as filters can be added to a system to remove certain contaminants from the water such as leaves and debris.

Why Harvest Rainwater?
Rainwater harvesting is becoming increasingly popular in the UK for both residential and commercial customers as rainwater can provide some of the cleanest, naturally occurring water that is available anywhere. Up to 50% of mains water used in the UK can be replaced with rainwater for domestic tasks such as washing laundry, cleaning, toilet flushing and car washing. With the rising costs of mains water supplies, rain harvesting is an effective, eco-friendly and cheaper way to provide water.
