Rainwater harvesting

We aren’t as rich in water in the UK as popular belief (and our reputation for rain) would have it. According to Environment Agency figures we only have 1,334 cubic metres per person per year. This is not a lot compared with France (3,065), Italy (2,785) and Spain (2,775). South east England is the worst off thanks to high population density and low rainfall. The Thames Valley has just 266m3 of water per person per year.
