Rainwater harvesting has various benefits and uses; however, harvesting systems have to operate and maintain to ensure water quality. Water also needs to be purified and filtered for use. Rainwater harvesting is the collection and storage of rainwater in natural water or artificially designed sources to prevent water runoff and meet future water shortage. The amount of water harvesting is influenced by factors such as the frequency of rainfall, essay rain water harvesting, the amount of rainfall, how rainwater is collected, and the size of the essay rain water harvesting to collect water.
The groundwater level is falling day by day due to various reasons like deforestation and ecological imbalance. Demand for water supply increases, especially in urban areas, due to the constantly increasing level of urbanization and industrialization. This is leading to overuse of groundwater and thus lower levels. The risk of water scarcity has increased substantially in the future and non-adherence to some effective solutions can be life-threatening. Water harvesting is very useful and caters to varied needs such as recharging the groundwater level, reducing electricity bills within the water supply and offering water supply anytime. Rainwater harvesting by individuals is essay rain water harvesting in all areas; It is sweet to reduce the concern of water shortage sooner or later.

Both ends of filter should have reduce of required size to connect inlet and outlet. This filter could be placed horizontally or vertically in the system. Sponge Filter It is a simple filter made from PVC drum having a layer of sponge in the middle of drum. It is the easiest and cheapest form filter, suitable for residential units. Methods of Roof Top Rainwater Harvesting Storage of Direct use storage tank. The storage tank has to be designed according to the water requirements, rainfall and catchment availability. Each drainpipe should have mesh filter at mouth and first flush device followed by filtration system before connecting to the storage tank. It is advisable that each tank should have excess water over flow Excess water could be diverted to recharge system.
Water from storage tank can be used for secondary purposes such as washing and gardening etc. This is the most cost effective way of rainwater harvesting. The main advantage of collecting and using the rainwater during rainy season is not only to save water from conventional sources, but also to save energy incurred on transportation and distribution of water at the doorstep. This also conserve groundwater, if it is being extracted to meet the demand when rains are on. Recharging ground water aquifers Ground water aquifers can be recharged by various kinds of structures to ensure ercolation of rainwater in the ground instead of draining away from the surface. Commonly used recharging methods are:- a b c d e f Recharging of bore wells Recharging of dug wells.
Recharge pits Recharge Trenches Soak ways or Recharge Shafts Percolation Tanks Rainwater collected from rooftop of the building is diverted through drainpipes to settlement or filtration tank. After settlement filtered water is diverted to bore wells to recharge deep aquifers. Abandoned bore wells can also be used for recharge. While recharging, entry of floating matter and silt should be restricted because it may clog the recharge structure. This is very important, and all care should be taken to ensure that this has been done. Recharge Pits Recharge pits are small pits of any shape rectangular, square or circular, contracted with brick or stone masonry wall with weep hole at regular intervals. to of pit can be covered with perforated covers.
Bottom of pit should be filled with filter media. The capacity of the pit can be designed on the basis of catchment area, rainfall intensity and recharge rate of soil. Usually the dimensions of the pit may be of 1 to 2 m width and 2 to 3 m deep depending on the depth of pervious strata. These pits are suitable for recharging of shallow aquifers, and small houses. Soak away or Recharge Shafts less pervious. These are bored hole of 30 cm dia. up to 10 to 15 m deep, depending on depth of pervious layer. At the top of soak away required size ump is constructed to retain runoff before the filters through soak away.
Sump should be filled with filter media. Recharging of dug wells Dug well can be used as recharge structure. Rainwater from the rooftop is diverted to dug wells after passing it through filtration bed. Cleaning and desalting of dug well should be done regularly to enhance the recharge rate. The filtration method suggested for bore well recharging could be used. Recharge trench in provided where upper impervious layer of soil is shallow. It is a trench excavated on the ground and refilled with porous media like pebbles, boulder or brickbats.
t is usually made for harvesting the surface runoff. Bore wells can also be provided inside the trench as recharge shafts to enhance percolation. The length of the trench is decided as per the amount of runoff expected. This method is suitable for small houses, playgrounds, parks and roadside drains. The recharge trench can be of size 0. Percolation tanks Percolation tanks are artificially created surface water bodies, submerging a land area with adequate permeability to facilitate sufficient percolation to recharge the ground water. These can be built in big campuses where land is available and Surface run-off and roof top water can be diverted to this tank. Water accumulating in the tank percolates in the solid to augment the ground water.
The stored water can be used directly for gardening and raw use. Percolation tanks should be built in gardens, open spaces and roadside green belts of urban area. It is most important to ensure that the rainwater caught is free from pollutants. Following precautionary measures should be taken while harvesting rainwater:- Roof or terraces uses for harvesting should be clean, free from dust, algal plants etc. Roof should not be painted since most paints contain toxic substances and may peel off. Do not store chemicals, rusting iron, manure or detergent on the roof. Nesting of birds on the roof should be prevented. Terraces should not be used for toilets either by human beings or by pets. Provide gratings at mouth of each drainpipe on terraces to trap leaves debris and floating materials.
Provision of first rain separator should be made to flush off first rains. Do not use polluted water to recharge ground water. Ground water should only be recharged by rainwater. Before recharging, suitable arrangements of filtering should be provided. Filter media should be cleaned before every monsoon season. Free Essays Topics Essay Checker Hire Writer Login.
