The inflow into Thumbe vented dam, the primary drinking water source for Mangaluru and its outskirts, has completely stopped, leading to a decline in water levels to 5.75 meters. Without imminent rainfall, the city may encounter severe water shortages, making careful water usage essential.
As temperatures soar and water consumption surges, authorities are pumping water round the clock from Thumbe dam. Over the past week, the water level has been receding by 8-10 cm daily. Though the dam’s gates remain shut to maintain storage at 6 meters, the lack of inflow has caused a steady drop. On March 19, levels fell to 5.40 meters, but a temporary release from Jakribettu dam raised it to 5.85 meters before dropping again.
Mangaluru receives 162 MLD (million liters per day), but with prolonged dry weather, a serious water crisis looms. Officials urge residents to use water wisely. Meanwhile, the AMR Power Project dam maintains a steady level of 17 meters.
Contingency Plans & Affected Areas
Previously, when Thumbe faced shortages, water was pumped from Harekala dam. If the situation worsens by May, similar measures may be needed. Localities like Surathkal, Kuloor, Katipalla, and Krishnapura are already experiencing scarcity.
The Jakribettu dam plays a crucial role in raising Thumbe’s levels, but its supply to Bantwal town has increased demand. Authorities urge immediate water conservation until the monsoon sets in.
