"The human race has taken water for granted and massively misjudged the capacity of the
earth's water systems to recover from our carelessness" -Barlow, M. & Clarke, T. (2002). The Fight to Stop the Corporate Theft of the World's Water. New Press.

Each year 10 thousand litres of rainwater falls on roof of an average 4 bedroom house. However, all this goes to waste and we pay for precious drinking water to be transported long distances.Rain water harvesting system can be as simple as a small rain water butt used for gardening or a more advance system that  filters and stores water in larger above or below ground tanks  and then can be controlled to pump water for garden, washing cars  and household use such as flushing toilets and clothes washing.

 Rain is collected in your existing guttering system and travels down your drain pipe. A filter is connected to the drain pipe which cleans out large debris such as leaves before it enters the tank. The size of your tank depends on the size of your rood (which determines the amount of water you will collect) and how much water you are going to use.Inside the tank there are many features to ensure the quality of your water. A calming inlet is used so that water enters the tank the bottom so that it doesn’t disturb the sediment at the base of the tank. If you purchase the correct sized tank, it will overflow at least twice a year which is a self cleaning mechanism. Also an overflow siphon gets rid of pollen and other debris floating on the top of the water. A floating submersible pump takes water from the middle of the tank which is the where the cleanest water is situated. If rainwater is used in the house, a floating switch is needed to automatically top up the tank with mains water when rainwater is low.

Below is a list of different sized tanks and other parts needed for a rainwater harvesting system. Subject to a survey by one of our installers, installation of a rain water harvesting system is £500.

Another way of conserving water is recycling grey water. The Hansgrophe “Pontos Aquacycle” recycles water used in the shower and bath and recycles it for use in the garden, flushing toilets and washing machine.
