Rainwater Harvesting

Recently the head of the Environment Agency stated that the UK could face severe water shortages in the next 25 years. Climate change and population growth are going to put a significant strain on our water reserves. The UK’s experiencing hotter summers with less rainfall. By 2050 our population is predicted to increase by 9 million. The result? Less water to go around.

On average a person uses 150 litres of water a day. Ideally, this level must reduce to 100 litres of water per day per person. Considering 63% of household water used for flushing the toilet, washing and bathing it stands to reason that reducing wastewater will push us towards the 100 litres a day target.

We have already spoken about Saving Money On Your Water Bill. By fixing leaks, taking showers instead of baths and installing water saving toilets and showers we can reduce water usage, this is a good start.

Six Water Usage Facts

1. All water used in the typical household is good quality drinking water
2. On average people drink 2 litres of water a day
3. Flushing Toilets uses around 70 litres of water per person per day (low flush toilets reduce this figure to 35 litres)
4. Washing machines use approximately 50 litres of water per cycle
5. Washing the car can use between 100-300 litres of water
6. Keen Gardener? then you’ll use 72 litres of water per square meter per month

As you can see flushing, washing machines, washing the car and watering the garden uses a hell of a lot of drinking water, when in fact rain water would suffice for these tasks.

Rainwater Harvesting is the solution
