The rainwater collection and reuse projects differ in scope from the village to river basin and even from one part of the globe to another. For example, in the southern US rainwater could be collected on sloped roofs and transfer to cisterns whereas in the Central African rainwater can be collected as high-volume flows, and because of the geographical difference can be stored for up to 20 years.[29]
Harvested rainwater can be stored in either roof-top rainwater tanks or in gravity-fed rainwater tanks. Gravity-fed tanks can be constructed using artificial soil or natural soil, as per the availability of space. A good example is the EITC, a non-technical platform for rainwater harvesting that takes rainfall data from different places. The rainwater is stored in tanks, and the excess water is released in the aquatic environment at suitable points. A study on Bulla Creek in Australia found that rainwater harvesting was one of the best strategies for stormwater management and preferred where there was no alternative water supply.[9]
As rainwater harvesting systems are usually smaller units, there is the potential to design the rainwater harvesting systems on smaller scales. In the long term, extensive rainwater harvesting systems with tertiary treatment may be needed if the water supply is to be increased to match the population increase. In addition, the impact of such large infrastructure on the environment is substantial and sustainable water management requires a re-thinking of the way we utilize resources like water even sustainable development in such a perspective is important. Indeed, suitable infrastructure may have to be implemented to increase the storage volumes. Potentially, a whole new set of possibilities can emerge for sustainable water management. With such systems, there may be ways of local resource conservation, pollution abatement, and improvement in the quality of life for people and the environment and the possibility of many new business opportunities. d2c66b5586
