The Chennai Metropolitan has been largely dependent on ground water for its sustenance. In turn these shallow well and tanks were recharged only during the annual rains .Due to rapid urbanization and industrialization,hundreds of water bodies adjacent to urban center and the extended city have already vanished or encroached upon and the rest are either in the verge of extinction or dumped with solid wastes and waste water effluents disturbing the local flora and fauna and also lives of people living nearby.
About two decades ago, a research project by the Centre for Environmental and Water Resource Engineering,IIT Madras estimated that about 650 waterbodies existed in the Chennai region. More than half of them were located south of River Adyar.At present,as the second Master Plan for Chennai indicates, only a fraction of them exists.
In a city like Chennai, where a large population of metropolitan area depends on ground water for sustenance, rapid urbanization and industrialization has taken a toll on the hundreds of water bodies. These water bodies have already vanished or encroached upon while the rest are on the verge of extinction or dumped with solid waste, it has adversely affected the flora and fauna and also the people living nearby. Studies indicate that 30 years ago 85% of Chennai’s topography was positioned to absorb and retain rain water, it has drastically dropped down to 15% of ground area presently.
The Greater Chennai Corporation has acknowledged the importance of ground water for sustenance and survival. The action plan for restoration of these water bodies has been carefully prepared with an objective to increase or restore water holding capacity of the lake, improve the quality of water and evolve a sustainable management plan post restoration. By understanding the biotic and abiotic factors that affect the condition of water bodies, various implementation measures are envisaged.
Implement holistic solid waste management
Source of pollution shall be treated aptly to meet the Tamil Nadu Pollution Control Board standards
The stake holder’s involvement is necessary to increase the efficiency in the project
Core groups to be formed for lake maintenance & training, capacity building shall be a part of it
Bio remediation and ozonisation technique to be implemented for treating the stagnant water
Beautification and fencing of water bodies along with sustainable maintenance plan
No water shortage will ensure every citizen have ample resource for their daily domestic to industrial activities.
Adequate water will reach to all the trees & plants thus maintaining the environment
Flora & Fauna
Every nature element will be provided with water for their ecological growth
Clean water bodies will prevent disease-spreading species to engulf Chennai
