The main use of water in the food processing industries include washing and sanitation, cooling and heating and a lot of other tertiary functions. In order to conserve water in this industry, the water must be reused in other processes, like rinsing water can be used in cooling towers. Machines and other units must be water-efficient in order that the consumption is less. Cooling towers must be modified in such a way that they recycle and reuse the water. Whenever and wherever possible, recycle water.
2Hotels and Motels-
The hospitality industry makes use of a lot of water for functions such as laundry, food preparation, cooling and heating, and to a small extent, mostly, for landscaping. In order to conserve water in this industry, there must be installation of ultra low-flush toilets, low-flow shower heads, and faucet aerator. There must be water recycling plants in order to make use of used water to an optimum best. The most water in a hotel or a motel is used in its restrooms. Hence, if the amount of water wasted here is least, it would mean a big saving of water.
Computers and Electronics Manufacturers-
The main use of water in this industry is by the circuit board and the electroplating industry. The main function of water here is that of rinsing. Besides, the rinsing of silicon wafers also requires a lot of water to be used. While the consumption of water is high, methods of reducing it are comparatively few. The two step that can be undertaken are the reducing of wastage in water, and also its proper recycling.s
Village Ponds: The original purpose of village ponds was to give sustainability to adjacent wells and for cattle drinking, bathing, etc.As village are absorbed into urban areas with increasing reliance on tube wells, the ponds are becoming cesspools. These ponds can function as storage reservoirs and recharge areas subsequent to desiltation and improvement of their water quality. Following recommendations are given: • No sewage should be diverted to ponds in order to maintain their water quality. • No garbage dumping should be permitted.
• Technique of in-situ improvement of water quality using aquatic plants and fishes can be introduced where necessary in order to avoid mosquito breeding. • Grass plantation should be carried out along the perimeter of ponds in the immediate sloping catchment. • Existing ponds are to be widened to the extent possible and deepened by 1.0m and nearby storm water drainage is to be used to fill up the additional capacity thus created. • Pond may be desilt and deepen with the assistance of draglines machines • Agriculture
Conservation of water in the agricultural sector is essential since water is necessary for the growth of plants and crops. A depleting water table and a rise in salinity due to overuse of chemical fertilizers and pesticides has made matters serious. Various methods of water harvesting and recharging have been and are being applied all over the world to tackle the problem. In areas where rainfall is low and water is scarce, the local people have used simple techniques that are suited to their region and reduce the demand for water. [pic]In India's arid and semi-arid areas, the 'tank' system is traditionally the backbone of agricultural production. Tanks are constructed either by bunding or by excavating the ground and collecting rainwater. [pic]Rajasthan, located in the Great Indian Desert, receives hardly any rainfall, but people have adapted to the harsh conditions by collecting whatever rain falls. Large bunds to create reservoirs known as khadin, dams called johads, tanks, and other methods were applied to check water flow and accumulate...
