Rainwater harvesting awareness program conducted for school students of SEVAI Shanthi Matriculation Higher Secondary School.


Rain water Harvesting Awareness building for students of  SSMHSS

Rainwater harvesting awareness program conducted for school students of SEVAI Shanthi Matriculation Higher Secondary School recently with a focus to insure water quality by utilizing the area’s rainfall.  The School teacher Ms.Meena mentioned, “Rainwater harvesting provides an independent water supply during regional water restrictions and is often used to supplement the main supply. It provides water when there is a drought, can help mitigate flooding of low-lying areas, and reduces demand on wells which may enable ground water levels to be sustained. It also helps in the availability of potable water as rainwater is substantially free of salinity and other salts. in the state of Tamil, rainwater harvesting is made compulsory for every building to avoid ground water depletion. It proved excellent results within five years, and every state took it as role model. Since its implementation, Rainwater harvesting systems can be installed with minimal skills. The system should be sized to meet the water demand throughout the dry season since it must be big enough to support daily water consumption. Specifically, the rainfall capturing area such as a building roof must be large enough to maintain adequate flow. The water storage tank size should be large enough to contain the captured water. For centuries, people have relied on rainwater harvesting to supply water for household, landscape, livestock, and agricultural uses. Before large centralized water supply systems were developed, rainwater was collected from roofs and stored on site in tanks. With the development of large, reliable water treatment and distribution systems and more affordable well drilling equipment, rain harvesting systems have been all but forgotten, even though they offer a source of pure, soft water. Utilizing the rainwater harvesting system provides certain advantages to the community. First of all, harvesting rainwater allows us to better utilize an energy resource. Systems for the collection of rainwater are based on simple technology. Water collected in the rainwater harvesting system can be put to use for several non-drinking functions as well. It also lessens the burden of soil erosion in a number of areas, allowing the land to thrive once again. Rainwater harvesting promotes self-sufficiency and fosters an appreciation for water as a resource. It also promotes water conservation. Rainwater harvesting also conserves energy as the energy input needed to operate. Local erosion and flooding from impervious cover associated with buildings is lessened as a portion of local rainfall is diverted into collection tanks. Rainwater is one of the purest sources of water available. Its quality almost always exceeds that of ground
or surface water”.-Govin
