Water Management In Chennai
The coastal city of Chennai has a metropolitan population of 10.6 million as per 2019 census. As the city lacks a perennial water source, catering the water requirements of the population has remained an arduous task. On 18 June 2019, the city's reservoirs ran dry, leaving the city in severe crisis. Although three rivers flow through the metropolitan region and drain into the Bay of Bengal, Chennai has historically relied on annual monsoon rains to replenish its water reservoirs since the rivers are polluted with sewage. With the population increasing over the decades, the city has faced water supply shortages, and its ground water levels have been depleted. An earlier Veeranam Lake project aimed at augmenting the city's water supply failed. However, the New Veeranam project, which became operational in September 2004, has greatly reduced dependency on distant sources. In recent years, heavy and consistent monsoon rains and rainwater harvesting (RWH) by Chennai Metro Water at its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
