Ghost month part 1 This is

Ghost month part 1

This is partly due to the high levels of water extracted, as well as polluted surface runoff and storm water flushed into them. let s not play the blame game, each of us needs to take responsibility and take action at home, at work and at play! As populations increase across the rest of the world, demand for water will also increase. If we dont reduce each individuals demand for water both directly and through embodied water the water situation will become dire The rainwater that falls on the rooftops can be harvested for groundwater recharge using appropriate techniques. This method may be applied for the roofs of existing houses/buildings as well as those to be constructed in future. It is estimated that a total of 2 MCM of water can be utilized for groundwater recharge at a cost of Rs. 92 crores. Lakes have often been misused for dumping of solid waste and sewage disposal. Water quality can be improved by replicating the principles of wetlands by the introduction of aquatic plants and fish in a systematic manner. Unique phenomenon of algae, bacteria symbiosis reduces the BOD Biochemical Oxygen Demand. The fish population acts as an ecological manipulator by grazing on the algal population. The storage capacity can be increased by desilting and widening. By desilting and deepening the lakes with the assistance of draglines machines, the lakes ghost month part 1 need to be linked up with storm water runoff in the vicinity to augment the inflow. This measure improves the quantity of groundwater recharge as well as the quality of available groundwater. In this method we creates a recharge basin and reservoirs on the flood plains by scooping out earth from the flood plains at appropriate locations and letting these reservoirs to be filled up by the expanded monsoon season flow of the river. The Yamuna flood plain comprising of 97 of area in Delhi offers a good scope for development of groundwater resources subsequent to the storage of monsoon waters on the flood plain itself. Out of 580 MCM of monsoon season flow allocated to Delhi about 280 MCM goes unutilized due to lack of storages. Abandoned quarries are available in the vicinity of urban areas. With some modification of their catchment area and/or linkage with some nearby channels these can be used to store water, which would ghost month part 1 run-off. Depth and width of these quarries can be increased where the volume of runoff waters can be calculated to be in excess of present storage capacity. Many ancient reservoirs have been disused due to change of catchment characteristics or due to destruction of feeding channel. These baolis/reservoirs can be reused as small recharge points. Major gains can be made only from the large reservoirs. These are abandoned course of rivers or streams and can be served as excellent ground water storage and recharge locations. Division of some of the monsoon flows into these channels greatly replenishes the declining water table for subsequent use. In the regional topography several small or large check dams are possible and may be created not so much for surface withdrawal but for recharging the falling ground water table. There are number of micro watersheds present in Delhi in the Ridge which provide excellent topographical formation to conserve monsoon runoff through simple recharge structures. 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.
