The rapid increment in the populace as well as the variations in the global climatic conditions has put the water supply at stake for the day-to-day usage. This has resulted in a number of issues in the cities of developing as well as the developed nations. For the order of overcoming this issue, the relevant organizations have initiated several different ideas and solutions. The solutions for this issue include the identification of alternative water sources as well as demand management. The alternative sources of water mentioned here count in storm water harvesting, rain water tanks, and purification and reuse of waste water.
This discussion is based on the critical analysis of the three solutions mentioned above for overcoming the issues caused by increasing global population. Storm water may be collected and reutilized either manually or by means of employing sophisticated automated systems. McLamb (2004) establishes that managing the storm water in urban areas in proportion to the treatment, storage, transport, and collection, is a public administrative service. The cost for this administration of storm water is paid by the private or public owners of roads and land in urban areas or in the development areas that are exposed to urbanization due to their categorization by a planning document or a local plan, or even a constructible area which is bounded by a municipal board.
Levett (2010) presents that it is a long established technique which is again now acquiring popularity; increasing number of people are seeking means for using the resources of water in a more intelligent manner. As suggested by Levario (2007), storm water harvesting is a sensible and easy method for acquiring water for agricultural as well as human usage. It may assist the households in being self sufficient in areas that are not in any way connected to the municipal networks and therefore it is a great help in saving water and reducing the demand for water by the populace.
As Kloss (2008) presents, the employment of storm water in urban areas cuts down the requirement of building novel dams; it secures the rivers from flowing, reducing the requirement of extracting the natural water sources in duration of the rainy season. In the same way, Kloss (2008) proceeds, it cuts down the maintenance and operating costs of the municipal networks. Several rural areas are currently dependent on storm water harvesting however the municipal services are served to the urban areas and thus they usually forget the employment of storm water.
Hendry (2003) has marked the greatest benefit of implementing storm water harvesting as its contribution towards the preservation of public reserves if water shortage occurs and its involvement of considerable energy savings by cutting down the pumping of water from the reserves at every house. It has been established by Kinkade-Levario (2007) that it entails a relief to the public drainage network and assists in raising awareness as well as establishing a direct association for the management of storm water.
Hagare (2013) has established that storm water harvesting makes a significant ...
