Rainwater harvesting is about adapting to climate-conscious methods of water management, by collecting rainwater off buildings, storing it and then using it carefully.

We have completed this for a storage shed, and the compost shed but would like to collect water off another building, and to develop a simple irrigation system from this.
(Approx costs £1,600 for large storage tank and all pipes additional £700 for good quality irrigation pump (running off solar) + labour)
