House sales affected by rainwater?

Water, rainwater harvesting

If you want to make your house more attractive to buyers in the current market then try this idea:


According to a UK survey, sponsored by Save the Rain a significant proportion of homeowners (1 in 3) would be more likely to buy a house if a rainwater harvesting system was already installed. With the increasing amount of rainfall falling from the skies over the UK this is a serious option that many sellers might like to consider to beat the current storms in the housing market.

A rainwater harvesting system will also save you money in the future as many of the water companies are threatening to put up their water rates by up to 60% over the next five years.

A major reason for installing a rainwater system is that it will help the environment by saving billions of water and prevent flooding which is now a serious threat to many homes in the UK. Not to mention the benefits of having harvested rainwater for your plants on tap when the next drought arrives – seems hard to beleive at the moment but it will!


It comprises a storage tank which can be buried under garden or path, drive or patio which collects water from the roof, filters off leaves and other debris and then stores it. Then, when you flush the toilet or run the taps, a pump in the tank comes on automatically.

The system holds about 3 weeks worth of water, depending on the size of the building. The tank can be topped up by the water mains in case of drought as it should not run dry. If the tank gets too full after heavy rain, an overflow pipe discharges the excess to a soakaway.

A rainwater harvesting system starts saving you water immediately, and will do so for many years, with minimal upkeep and maximum reliability.There is a very useful website which identifies key questions that you might now be asking about rainwater harvesting systems such as:
