In a significant achievement, the Neyveli Lignite Corporation India Limited (NLCIL) announced the successful completion of the long-awaited and crucial project for the permanent diversion of the Paravanar river course. The momentous occasion was marked on August 21, 2023, as the NLCIL accomplished the task, solidifying its commitment to safeguarding communities and agricultural fields from the vagaries of nature.
With the major portion of 10.5 kilometres of the total 12 kilometres already completed, NLCIL embarked on the final phase of the project covering the remaining 1.5 kilometres on July 26, 2023. This momentous endeavour was undertaken in close proximity to Mine-2’s cut face, with the temporary alignment of the Paravanar river course situated merely 60 meters away.
The Paravanar river plays a crucial role in managing stormwater from a vast catchment area spanning over 100 square kilometres, encompassing regions in the north-west and southern zones. The necessity to protect the local communities and their agricultural lands from inundation during heavy and continuous rainfall prompted NLCIL to take on the responsibility of ensuring a secure and permanent waterway through the diversion of Paravanar.
Covering an estimated area of 18 hectares, the permanent diversion of Paravanar river course was not just a feat of engineering, but also a testament to NLCIL’s dedication to sustainable development and community welfare. Even before the completion of this endeavour, NLCIL had been effectively utilising the Paravanar river water to irrigate numerous acres of land year-round.
With the commissioning of the permanent river course, a significant extension of agricultural land is set to benefit from enhanced irrigation opportunities. Moreover, the consistent flow of water in the Paravanar river will also contribute to the augmentation of groundwater resources in the area, providing an added boost to regional water security.
