Harvesting rainwater helps conserve our most precious of natural resources: water. Why use drinking water to flush your toilets, wash your clothes or water the garden?
Systems are sized based on the roof area and estimated annual rainfall combined with the likely demand. Typically the rainwater is stored in a tank buried in the garden. A pump then transfers it when required directly to the toilet or washing machine, or into a storage tank in the loft. A loft tank uses gravity to generate the pressure so a higher pressure can be delivered for garden hoses etc with a directly pumped system.
