Rain Water Management

Dams, ponds and pipelines are apart from the traditional development of water sources. However, rainwater harvesting is a refreshing approach towards an integrated, environment friendly and sustainable urban water resources development initiative.
I many part of the world, the uses of rainwater are expending in order to accommodate the needs of the environment and growing water supply demands. Unfortunately, for most of it, this is the only choice. In addition to providing a dependable and locally controlled water supply, proper rainwater management can also provide tremendous environmental benefits. It can help in reducing or mitigating urban flash flood problems through a reduction of peak storm runoff, and also assist in reducing sedimentation and pollution problems. The utilization of rainwater harvesting should also be related to other aspects of living like food and water security, environmental rehabilitation, protecting wetlands and now in coping with climate change.
Rainwater management focuses on providing the right storm water solution. With a full range of new technologies, rainwater management can provide an engineered solution for many of our needs. A good rainwater management system can be a cost effective approach to the escalating issue of water conservation and management for now and the future. However, there has been a change in thinking on the single function view of traditional ‘storm water management’ to the integrated and comprehensive perspective that is captured by the term ‘rainwater management’.
Storm water suggests there is a problem, whereas rainwater is a resource. Traditional storm water management is reactive. I only deals with the consequences of rare extreme events. Rainwater management, on the other hand, is proactive in managing all rainfall events that occur in a year. Rainwater management integrates drainage infrastructure planning with relevant planning processes, in order to address the impact of rainwater on community values. I is a necessity in the planning processes, the approach of design with nature to integration of rainwater management with community.
The desired outcome is to improve both natural and built environments in an urban setting. This means determining how rainwater management objectives can be integrated with land development processes and tools to mitigate the cumulative impact of landscape alteration, and produce cumulative watershed landscape benefits. In general, rainwater management is aimed at resolving existing problems and protecting environmental resources as both are associated with land use change, either past or proposed.
