Planet of the apes part 1

This includes costly upgrades and maintenance of pipes, sewers and treatment facilities. Erosion, salinity and desertification. Water consumption for agriculture alters the natural water cycle in many areas of Australia. This degrades production areas and intensifies other environmental problems such as land clearing and desertification. Degradation of water bodies. Many of our rivers, wetlands and bays are degraded. 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 would 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 otherwise 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.
