Cluster of abandoned quarries to be networked to form a significant storage structure for Chennai’s water supply
The HinduThe cluster of abandoned quarries in peripheral areas, which serve as a buffer source of freshwater, may be networked to form a significant water storage structure to tackle Chennai’s growing needs. The Water Resources Department along with Chennai Metrowater has proposed to create an integrated network of the abandoned quarries in various areas such as Sikkarayapuram, Erumaiyur, Tiruneermalai and Chettipunyam in Chengalpattu district to tap resources for the city’s drinking water supply. A proposal is being chalked out to network the cluster of abandoned quarries to create a storage structure with a capacity to hold nearly 4,000-5,000 million cubic feet of water. Citing the study on ‘Innovative Water Management Using Abandoned Quarries for Urban Water Supply and Flood Mitigation’, L.Elango, former professor, Department of Geology, Anna University and visiting faculty IIT-M, said diversion of water from Adyar and Palar rivers, which carry peak flow during monsoon, to nearby quarries would help control inundation and also stave off water scarcity during summer.
