Overview
- The wall of one chamber of a twin-chamber Kerala Water Authority reservoir at Thammanam gave way around 2–2:30 a.m., unleashing tens of millions of litres of water into nearby streets and homes.
- Several houses were inundated, vehicles were damaged, and a primary health centre lost medicines and equipment, with no casualties reported.
- Authorities said drinking water service to parts of Kochi would be hit, estimating about 30% impact, as emergency pumping from Aluva and Maradu and tanker deliveries are deployed to maintain supply.
- The intact chamber remains in use with its storage raised to roughly 85 lakh litres after checks for minor leakage, with rescheduled pumping in three daily shifts to stabilise distribution.
- Preliminary views point to age-related structural weakening, detailed inspections and compensation assessments are underway, and the state is considering a stricter inspection protocol for ageing KWA structures, noting 161 disused tanks statewide.
