Water supply from the Krishna River to Chennai is expected to resume in mid-May [1, 2].
This restoration of flow is critical for the city's drinking water infrastructure as the region faces ongoing challenges with water scarcity and reservoir levels.
Officials say the release of water from Andhra Pradesh was halted to allow for maintenance work on the Kandaleru-Poondi (KP) Canal [2]. The canal is a primary artery for transporting water from the Krishna River into the city's reservoir system. The maintenance was necessary to ensure the long-term stability of the infrastructure, though it caused a temporary suspension of the flow.
Despite the resumption of the supply, concerns remain regarding current storage levels. Combined storage in the lakes supplying drinking water to Chennai has dipped below last year's level [1, 3]. This decline indicates a potential vulnerability in the city's water security, especially as the city moves deeper into the summer months.
City officials have described the water reserves as stable despite the dip in storage levels [1]. The disparity between the stability of the reserves and the decline in total volume suggests a managed approach to water distribution to avoid shortages.
Local authorities are coordinating with Andhra Pradesh to ensure the flow is restored according to the schedule. The return of the Krishna River water is expected to provide a necessary buffer for the city's reservoirs, which have seen a decrease in volume compared to the previous year.
While the maintenance work on the KP Canal is completed or nearing completion, the city continues to monitor the lake levels closely. The goal is to ensure that the drinking water supply remains uninterrupted during the period of transition back to full capacity.
“Water supply from the Krishna River to Chennai is expected to resume in mid-May.”
The resumption of the Krishna River water supply highlights the dependency of Chennai on inter-state water sharing agreements and the maintenance of the KP Canal. While city officials claim reserves are stable, the fact that lake levels are lower than the previous year suggests that the city's water security remains precarious, making the timely restoration of the KP Canal flow essential to avoid a summer water crisis.
