Rain - a valuable resource

摘要

Thanks to the introduction of mains water piped directly into their homes, Victorians soon dispensed with harvesting rainwater from the roofs of their buildings. Yet, 100 years on, the concept of capturing rainwater for non-potable uses is now firmly back on the agenda, and is expected to become a major part of new-build projects going forward in the UK - credit crunch permitting.rnIndeed, sales of rainwater harvesting equipment have gone up by 300% in the past two years alone, and are continuing to rise. Several drivers have been pushing the use of this cost-effective and simple technology over the past 12 to 18 months or so.
