The lake receives more water for wastewater than the natural flow of ' water '
It is a very interesting and important subject to discuss. Water is a limited natural source. We need water for our daily lives. So we must conserve the water. But humans use water in a high amount. Waste water in large quantity as well. Waste of water will lead to water shortages in the coming years. In addition, the contamination causes the water to become acidic and poisonous. This water can not be used for any purpose. Factories need water for the production of their goods. Water is one of the raw materials needed in large quantities. These factories let out poisonous chemicals in lakes and other water resources. It contaminates the water and makes it unusable. This water can not be recovered or purified by any means. Therefore, it can not be used again. Today the pollution has increased. The discharge of wastewater into bodies of water is one of the causes of pollution. Wastewater is a waste transported by water, in solution or suspension, which is destined to be removed from a community. Also known as wastewater, it is more than 99% water and is characterised by volume or flow rate, physical condition, chemical constituents and bacteriological organisms.
