This blog post by Prakash Apte, draws attention to the increasing water demand in urban areas because of industrialisation and population growth by giving the example of Mumbai and points at the current scenario of the lack of availability of adequate and safe water supply to meet the needs of the ever increasing population in the city.
The author proposes that rainwater harvesting can be a viable solution in cities such as Mumbai to meet this increasing demand for water and can provide an opportunity for equitable, efficient and sustainable use of water resources.
There is an urgent need for evolving a rainwater harvesting system that is sustainable, replicable and economically viable and argues that the benefits of using rainwater harvesting can lead to a range of social, economic and environmental benefits and can contribute substantially to improving the quality of life in Mumbai.
Geographic Information Systems (GIS) has a role and application, in promoting a system and methodology for rain water harvesting and for providing the data needed to enable its large scale implementation in the context of Mumbai.
