Essay on rainwater harvesting in tamil.
For this Rain Water Harvesting (RWH) seems to be a beneficial method for minimizing water scarcity. RWH is a technology where surface runoff is effectively collected during yielding rain periods.
What is Rainwater Harvesting? Rainwater harvesting is the storing of rainwater during the monsoon season for the purpose of using it during periods of water scarcity. Generally speaking, it is a process used for collecting and storing rainwater for human use. Rainwater harvesting is best described as the technique by which rain water is accumulated and stored with the intention of reusing it.
Rainwater Harvesting is one of the quickest and easiest ways to reduce water consumption and become more efficient. The idea behind the process is simple. Rainwater is collected when it falls on the earth, stored and utilized at a later point. It can be purified to make it into drinking water, used for daily applications and even utilized in large scale industries. In short, Rainwater.
Rainwater harvesting is a type of harvest in which the rain drops are collected and stored for the future use, rather than allowing them to run off. Rainwater can be collected from rivers or roofs and redirected to a deep pit (well, shaft, or borehole), aquifer, a reservoir with percolation, or collected from dew or fog with nets or other tools.Its uses include water for gardens, livestock.
Broadly there are two ways of harvesting rainwater, namely; surface runoff harvesting and rooftop rainwater harvesting. Rainwater harvesting is the collection and storage of rain for reuse on-site, rather than allowing it to run off. The stored water is used for various purposes, such as gardening, irrigation, etc. This article discusses multiple methods of rainwater harvesting.
South India has a rich tradition of tanks with the three southern states of Tamil Nadu, Karnataka and Andhra Pradesh contributing to close to 92% of the total irrigation by tanks in the 1970s. Two decades later, this number dwindled to close to 53%. A decade after that, in 2001, the total contribution of tank irrigation in all of India was estimated to be just around 5.18%.
Our rainwater harvesting systems filter water before it enters the storage tank. Debris such as moss, twigs and leaves are separated from the water before it enters the tank through a calmed inlet. Another filter, which is part of the pump assembly, rids the water of small particles before it is pumped to serviced appliances. The water harvested with these systems meets requirements for non.
