Cauvery Rains Relieve Trichy: Drinking Water Crisis Averted

Trichy's water supply situation has significantly improved due to heavy rainfall in the Cauvery catchment areas, leading to a substantial increase in water inflow to the Mettur dam. This has eased the previous shortfall between drinking water demand and supply, reducing it from 15-25 MLD to approximately five MLD. Corporation officials have stated that daily drinking water supply will continue uninterrupted, and serious water austerity measures are not required at this time.

Previously, a diminished outflow from the Mettur dam caused a 15% drop in Trichy's water supply. However, for the past two weeks, a consistent outflow of about 1,000 cusecs into the Cauvery has been observed. This increased flow has taken over a week to reach Trichy and surrounding areas, with about 500 cusecs reaching Mukkombu for the past week, aiding in the recharge of collector wells. This fresh inflow has boosted the city's net drinking water yield by over 20 MLD, which is expected to be sufficient until the northeast monsoon.

Water resources department officials noted that if the Cauvery inflow persists above 1,000 cusecs for the next ten days, it will significantly help recharge the groundwater table beneath Kollidam. The local body is also considering additional minor borewells to address any remaining supply shortages.
