If we are to avert a devastating shortages, we must look at alternative water sources, both in our homes, and in the planning of new developments. Rainwater expert Heather Kinkade-Levario builds on her award-winning book, "Forgotten Rain with Design for Water". This accessible guide is the most up-to-date book on the market dealing with alternate water collection, with a special focus on rainwater harvesting in the urban environment. Aspects include: Passive and active systems set-up; Storage; Stormwater reuse; Distributional Purification; Analysis; Filtrations. Numerous case studies outline the process of water collection from landscape, residential, commercial, industrial, school, park and municipal systems. Other accessible (affordable) alternate sources include cooling tower bleed-off water, air conditioning condensate, graywater and fog collection. The book provides the necessary guidelines to set up passive harvesting techniques to anyone harvesting techniques to anyone making development decisions -- engineers, landscape architects, developers, policy-makers, planners and land-owners.
