The National Water Supply and Drainage Board (NWSDB) has restricted water supply in parts of the Batticaloa District to four hours a day due to declining water levels at the Unnichchai Reservoir amid prevailing dry weather conditions.
NWSDB Chairman A.M.P.C.T. Bandara said the water supply is suspended daily from around 11.00 a.m. to 3.00 p.m. as the reservoir’s water level continues to fall.
However, Bandara said NWSDB-operated water treatment plants across the country continue to function as usual.
He said arrangements have been made to produce and distribute water at maximum capacity from the treatment plants to maintain supplies.
According to the NWSDB Chairman, Sri Lanka produces approximately 2.8 million cubic metres of water each day. Around 23% to 24% of this supply comes from major reservoirs, while nearly 65% is sourced from rivers and streams.
The Kelani River alone provides close to 600,000 cubic metres of water daily, accounting for nearly one-third of the country’s total water supply.
Bandara said the effects of the prevailing dry weather have so far been limited to the Batticaloa and Monaragala districts.
Water supply is also being managed in the Bibile and Medagama areas of Monaragala due to shortages in available water sources, he added.
