A great example of what can be done, put together by nephew David Turnbull in his house in Swanage. He’s installed two 500 litre tanks under his raised garage to collect water from the roof of the house. Then the water is fed automatically into the house for showers, washing machine etc.
It’s such an elegant and efficient way of saving water. I’d love to learn from it for Hedgerley. Not least because when the house was built in the 1930s only rainwater was available and it was stored in two underground cisterns and what is now the swimming pool. Time to bring the cisterns back into use if we can.
