Chennai Manali Lake Restoration Triples Capacity And Reduces Flood Risk After Monsoon
Chennai’s Manali Lake has been transformed following a Rs 6.70 crore restoration, tripling its water-holding capacity to 12 lakh cubic feet. The 29-acre waterbody, located in Ward 20 of the Manali zone, has filled to capacity after recent monsoon rains, easing flood risks in nearby localities. Beyond water storage, the redevelopment features strengthened bunds and enhanced public amenities, signalling a major step in sustainable urban infrastructure and community-friendly city planning.
The Greater Chennai Corporation (GCC) implemented the restoration under the AMRUT scheme and the Corporation Capital Fund, raising the lake’s depth from 1.2 metres to 4 metres. Previously, limited storage capacity restricted its ability to manage waterlogging or recharge groundwater, leaving surrounding neighbourhoods vulnerable during heavy rains.“Urban waterbodies are crucial for building resilient cities,” an official from GCC said. “The upgraded Manali Lake not only improves flood management but also enhances local water availability and public spaces.”
The redevelopment incorporated more than just structural improvements. Walkways, seating arrangements, handrails, children’s play areas, lighting, parking, drinking water points, toilets, and a security guard room were added to encourage inclusive use. Bund reinforcements and better water retention measures were designed to ensure long-term sustainability, reflecting an integrated approach that combines ecological restoration with community needs.Experts note that urban lakes serve multiple functions beyond aesthetics. “Reviving waterbodies delivers environmental, social, and economic benefits,” said a senior urban planner. “They control floods, recharge groundwater, and provide accessible green spaces, which are essential for inclusive urban development.”Since the recent rainfall, the lake has reached full capacity, significantly reducing waterlogging in nearby localities. Residents reported that the restored lake has improved neighbourhood scenery and created a safer, more welcoming space for recreation. Improved water retention is also expected to support local groundwater tables, enhancing water security for households and small-scale irrigation.
Chennai faces persistent flood challenges due to high-density development and constrained drainage. Strategic initiatives like the Manali Lake restoration illustrate how cities can integrate ecological planning with urban infrastructure to improve resilience. By combining water management, public amenities, and structural reinforcement, the project sets a benchmark for sustainable and inclusive urban development in India.
