Importance Of Rain Water Essay

Water has an ability to absorb pollution upto a certain level without influencing its quality. There could be a problem of water pollution only if the pollution loads exceed the natural regenerative capacity of water. Thus, to control water pollution, there is a need to reduce pollution loads from various anthropogenic activities to the natural regenerative capacity of the water resource. The advantages of the preservation of water quality are enormous. It not only supply water for various agricultural, industrial and household uses but also reduces the health and economic burden of the country.

8.1 Need of water resource management: conservation and utilization

Water is a resource for the whole community. Its desired quality and quantity

Since antiquity, our ancestors have met their minimum water requirements by collecting rainwater in various structures which serve as lifelines for local people till today (insert table). However, these conventional technologies have gained inattention and ignorance over time. They need to be revived and rejuvenated by combining this knowledge with modern technologies and scientific tools. Rainwater harvesting should be encouraged by Government of India by providing subsidies for the establishment of water harvesting infrastructure. The parking lots and footpaths should have breathing spaces for recharging ground water as concretization in the form of new roads, flyovers and pavements has stopped every single accessible path for reviving ground water. The benefits of harvesting rain water are manifold if it will be implemented to domesticated areas. The filtered and stored rainwater can be used for various household uses, for washing, heating and cooling applications in industries and also for small scale irrigation purposes in agriculture. Therefore, CGWA (Central Ground Water Authority) has directed all residential groups including institutions, schools, hotels and industries to set up roof top rain water harvesting systems in their

Presently, water quality monitoring is done by CPCB at 2500 monitoring stations under a three tier program: Global Environmental Monitoring System (GEMS), Monitoring of Indian National Aquatic Resources System (MINARS) and Yamuna Action Plan (YAP). Regarding frequency, it is noticed that 68% of the stations monitor water quality on a monthly basis while 32% on half yearly basis. There is an urgent need to increase the number of monitoring stations as well as their frequency. The water quality should be reviewed every month and the results should be made available on the website for ensuring
