Contact SupplierWater is the key to life. Of all the planets known to man – Earth deserves to be called as the Water Planet. Rain being main source of fresh water its importance in conservation was not understood till now In scientific terms, water harvesting refers to collection and storage of rainwater and also other activities aimed at harvesting surface and groundwater.
In general, water harvesting is the activity of direct collection of rainwater. The rainwater collected can be stored for direct use or can be recharged into the groundwater.
Rain is the direct form of water that we know in the hydrological cycle, hence is a primary source of water to us. Rivers, lakes and groundwater are all secondary sources of water. In present times, we depend entirely on such secondary sources of water. In the process, it is forgotten that rain is the ultimate source that feeds all these secondary sources and remain ignorant of its value. Water harvesting means to understand the value of rain, and to make optimum use of rainwater at the place where it falls.
HOW MUCH WATER CAN BE HARVESTED?
The total amount of water that is received in the form of rainfall over an area is called the rainwater endowment of that area. Out of this, the amount that can be effectively harvested is called the water harvesting potential.
Water harvesting potential= rainfall(mm) x collection efficiency Rainwater can be harvested for tow purposes:
Different Types of Rainwater Harvesting
Rainwater harvesting is the accumulation and deposition of rainwater for reuse before it reaches the aquifer. Uses include water for garden, water for livestock, water for irrigation, and indoor heating for houses etc.. In many places the water collected is just redirected to a deep pit with percolation. The harvested water can be used as drinking water as well as for storage and other purpose like irrigation.
