Quiz 11: Water Resources and Water Pollution
Colorado River basin is situated in southwest part of U.S. The river is facing water shortage and if something is not done early then it would result into drought. This river is a source of water for many arid cities. There are several factors that have led to the river to drought. But here we are discussing about three of those major problems. To deal with the shortage or drought we need to store water for future use. Freshwater shall not be wasted and shall be recycled and reused again. The main source of water is surface water and groundwater. Due to the over pumping of water, the underground water is prone to drought. The aquifer once become empty it would be impossible to recharge it again. Composting toilets are another idea for sustainable water resource. These are Modern toilets which uses no water. Water shall be recycled and used for watering gardens and lawns instead of freshwater. Also the water shall be allowed to reach oceans and save water as much as possible.
Water conservation shall be done for the preservation of water and keep it for future generation as well. Water is a scarce resource which is on the verge to deplete. Water is a necessity for everyone. One can sustain without food for few days but not without water. Water conservation plan shall be made everywhere and strict actions shall be taken to follow and maintain it. Every day in a school about 260litres of water is wasted in toilets per day. Also 151 liters of water is wasted at drinking water taps. A plan for conservation of water shall be made so that the waste shall be minimized. The goal for conservation of water shall be made. The goal of plan is to minimize the waste of water. 1. Composting toilets shall be used in schools to save water. 2. Recycled water shall be used to water plants and in toilets as well. 3. Freshwater shall be used less. 4. Water shall be treated to use again. 5. Storing containers shall be kept at drinking tanks to store water loss through taps. The forecast is made to estimate the future demand of water. There is a difference between estimation and actual consumption but still we get idea and can plan our schedule or usage accordingly. The water conservation is much more important because our survival depends upon it. The plan shall be made and strictly followed and maintained. These plans help a lot in saving water. This reduces water waste.
(a) Calculate the per capita water consumption per day in 2005. Substitute for total consumption of water and for total population in 2005. Hence the use of per capita water is Calculate the per capita water consumption per day in 2025 Substitute for total consumption of water and for total population in 2005. Hence the use of per capita water in 2025 is (b) Calculate the per capita water consumption per year in 2005. Substitute for total consumption of water and for total population in 2005. Hence the use of per capita water consume in a year 2005 is Calculate the per capita water consumption per year in 2025 Substitute for total consumption of water and for total population in 2005. Hence the use of per capita water per year in 2025 is
