Design and Installation of Rainwater Collection and Recycling Systems

In the UK approximately 100,000 litres of rainwater falls on the average 4 bedroom detached property in a 12 month period. Thats a lot of water which just ends up down the drain. According to the Environment agency we use an average 150 litres of mains water per person per day. For a family of four thats a staggering 219,000 litres a year.

We cant stop using water - but we can stop wasting it!

Our rainwater harvesting systems can help you conserve water and save money.


Figures vary slightly depending on their source, but according to according to Environment agencies water usage chart for 2009 -10 we use 12% of this water for clothes washing, 7% outdoors and 26% for toilet flushing. That equates to 45% or 98,550 litres of water per year. The amazing fact is that this 98,550 litres of water does not need to be mains water. i.e. it does not need to be "wholesome" or fit for consumption. Thats where Rainwater Harvesting fits in. All of this none wholesome water requirement can simply be provided by the water that falls on the roof. If you further factor in the natural softness of rainwater, then you reduce the need for chemical de-scalers and reduce the need for chemical detergents and fabric softening agents among other things, which all affect water quality and the environment.

How Do I Choose the Right Rainwater Collection System?

There are several different types of Rainwater Harvesting systems available, generally they are direct or indirect. A Rainwater Harvesting system usually consists of a large underground storage tank, that rainfall is diverted into and thus harvested. It is then pumped into a building "directly" to services as required. Or it is pumped into a building and into a small storage tank. From here it is piped to services as required, this is known as indirect. Both systems have mains water back-up so that if a rainwater store runs dry, there is always water available for use.

The average domestic rainwater harvesting installation costs approximately £3,000 - £6000 installed. Costs are affected by type of system used, size of property and location of equipment and services. It also depends on the amount of ground works required too. Correctly sized it will provide all of the household washing machine, toilet flushing and garden water requirements, complete with automatic mains water back-up.
