Ground Water in Dhaka City Essay

capital of Bangladesh is the capital city of Bangladesh which has a commonwealth of about 12. 5 millions and its population rate is over 5%. project population is about 22 million by 2025. capital of Bangladesh is in a flash the 7th largest populated city in the world and it is anticipated that Dhaka will be the 2nd largest city in the world by 2020. This city is full of problem and one of the major problems is irrigate system crisis. Although Bangladesh is liberal in water resource, but there remains lack of secure water. The cities in Bangladesh are the centre of employment, communications and development.So, people are apace migrating in these cities from rural areas place putting additional pressure on the infrastructure and water resources. For this huge population in Dhaka city, water demand is also huge. And maximum portion of this greater demand is fulfil by flat coat water. The daily requirement of water in Dhaka city is about 200 crore liters while WASA supplies 18 0 crore liters, leaving a shortage of 20 crore liters. Out of this 180 crore liters of water, 154. 50 crore liters of water are supplied from ground water.All most 85%-87% of water is supplied from under the ground and of them are from surface water. To supply this massive amount of water we involve to extract a lot from the ground. Everyday demand for water is change magnitude and we are adding new pumps. In 1998, there were only 243 water pumps to override water in 2004 it was 440 but now it is 560. Each of the pumps lifts 3,000 liters of water in a minute. And this is also making some problems. For this heavy extraction water level is going down rapidly.In some statistics I corroborate found that the level of underground water has dropped down to 61. 18 meters. The second-rate rate of decline of water level varied from 1 m to 2. 50 as the report of DWDB. Ground water depletion situation is onerous in the central part of the city compare to the areas close to river bank, say s DWDB. If this sustain to happen then in future it will be toilsome to lift up underground water. Moreover, the increasing number of pumps and subsequent depletion of groundwater defer increases the risk of disasters like landslide, subsidence and earthquake.
