The prevailing dry weather across the island has led to water supply disruptions in several regions, affecting parts of Colombo, Kalutara, Ratnapura, Matara, and Kandy, according to the National Water Supply and Drainage Board (NWSDB).

The declining water levels in reservoirs and other sources have strained the supply, prompting the NWSDB to urge the public to use water sparingly and avoid non-essential activities such as washing vehicles and gardening. In severely affected areas, water is being distributed via bowser trucks.

Meanwhile, the Ceylon Electricity Board (CEB) reported an increase in electricity generation costs due to the low water levels impacting hydropower production. As a result, more thermal and fuel oil power plants have been activated.

CEB Media Spokesperson Dhammika Wimalaratne stated that the Norochcholai Power Plant is now operating at its maximum capacity of 900 megawatts, while the Kelanitissa ‘Naphtha’ Power Station and the Sapugaskanda Power Station have also been brought online.

Currently, hydropower contributes 20% of electricity during the day and 40% at night, while solar power provides additional generation during daylight hours.

Authorities urge the public to conserve both water and electricity as the country grapples with the ongoing dry weather conditions.
