ECONOMYNEXT — Sri Lanka’s National Water Supply and Drainage Board (NWSDB) said there will be no revision to water tariffs until June 30, as the agency manages a precarious supply situation in the Western Province due to falling reservoir levels and saltwater intrusion.
NWSDB Chairman Chandana Bandara said that according to the board’s policy, price revisions are considered only twice a year, ensuring that current rates remain fixed for the first half of the year.
“There have been no plans to increase water bills yet. The current price will remain until June 30th,” Bandara said. “If a revision is to happen, it would only take place in the second half of the year.”
While major Mahaweli reservoirs are holding at 55-60 percent capacity following rains in December and January, the NWSDB is facing a critical shortage in the Western Province.
Water levels at the Labugama and Kalatuwawa reservoirs have plummeted, with enough stocks to last only about 20 more days.
The drop in river flow has also led to saltwater intrusion in the Kalu and Kelani rivers, complicating the treatment process.
Approximately 150,000 consumers are directly impacted by the dwindling reserves in the Labugama and Kalatuwawa systems.
To manage the shortage, the NWSDB has initiated a systematic water schedule for towns along the High-Level Road, including Padukka, Hanwella, Maharagama, and Pannipitiya.
“We are implementing a systematic water cut,” a Deputy General Manager (DGM) of the Board said.
“In Padukka, which has 18,000 connections, we carry out a 24-hour cut, followed by four days of continuous supply. Consumers are being notified of these interruptions via SMS.”
The Chairman noted that the board’s ability to meet growing demand was hampered by a series of shocks to the economy since 2019, including the Easter Sunday attacks, the COVID-19 pandemic, and the 2022 economic collapse. These events stalled several key infrastructure projects.
To address the deficit, the NWSDB is currently in the procurement stage for several major projects, including a 50,000 cubic meter capacity addition to the Ambathale treatment plant and a new 180,000 cubic meter plant in Welivita.
“It will take about two to three years for the new Ambathale plant and the Kalu Ganga project to be 100% completed and added to the system,” Bandara said, adding that the board is also working on new reservoirs in Paliyaru, Mannar, and the Vavuniya district to bolster national capacity.
