Work on the century-old Wellington reservoir in Cuddalore is accelerating. The ₹130 crore rehabilitation aims to secure irrigation for 63 villages and ensure dam safety for the next century.

  • The rehabilitation of Wellington reservoir is being executed at a cost of ₹130 crore.
  • Over 60% of the construction work has already been completed.
  • The reservoir serves an ayacut of 9,737 hectares across 63 villages.
  • New technology involving 11-foot deep concrete walls is being implemented.

The reconstruction and strengthening works of the Wellington reservoir, a vital waterbody in the Tittakudi taluk of Cuddalore district, have entered a high-speed phase. Built in 1923, this historic structure is undergoing a massive ₹130 crore overhaul to address recurring structural failures and enhance irrigation efficiency for the region.

Historical Context and Structural Distress

Located in Keelacheruvai village, the reservoir was originally designed to capture floodwaters from the Vellar River. For over a century, it has been the lifeline for 63 villages in the Tittakudi and Vriddhachalam taluks, irrigating approximately 24,059 acres of farmland. However, the reservoir's earthen bund has faced persistent distress due to subsurface soil characteristics.

Historical records show that significant efforts were made in the past to stabilize the structure. In 1996, a ₹5 crore repair was conducted with World Bank assistance, and in 2010, a ₹29.71 crore reconstruction was undertaken. Despite these interventions, monsoon-induced erosion continued to threaten the integrity of the bund and the main canal.

The Impact of Infrastructure Decay

BozokMedia analysis shows that the degradation of the main canal was a primary driver for this massive investment. Vegetation growth and collapsing canal banks often obstructed water flow, preventing water from reaching tail-end farmers. Furthermore, during heavy rains, canal breaches frequently led to the flooding of nearby farmlands, causing significant crop damage.

The implementation of advanced concrete shielding and wider surplus gates will safeguard the reservoir's functionality for the next 100 years.

To combat these issues, the Water Resources Department (WRD) has moved beyond temporary fixes. The current project involves building a concrete wall to a depth of 11 feet and using liquid concrete to prevent seepage, alongside strengthening the bund to a height of 11 meters.

Engineering for the Next Century

A significant aspect of the upgrade is the widening of the surplus gates. The existing gates, which were three meters wide, are being expanded to eight meters each. This allows for a massive discharge capacity of 32,000 cubic feet per second, providing much-needed safety during extreme flood events. Additionally, a 900-meter-long concrete wall is being constructed along drainage channels to ensure long-term stability.
