The National Water Supply and Drainage Board (NWSDB) has imposed a 12-hour water cut across Homagama and surrounding areas on Tuesday, April 7, as prolonged dry weather pulls down reservoir levels feeding Colombo’s southern suburbs.

Supply will be suspended from 8:00 a.m. to 8:00 p.m. across what NWSDB calls “Homagama Zone 02.” The affected areas include Homagama town, Wekanda, Pinketha Road, Walawwa Road, Gamunu Mawatha, Athurugiriya Road, Galavilawatta, Niyandagala, Magammana, Mahakatuwana, Deniya and the Diyagama University area.

NWSDB cited “prevailing dry weather conditions” as the cause and asked residents to use water sparingly through the cut window. A separate restriction was earlier imposed in Palanwatta and surrounding areas — including Mattegoda, Deepangoda, Brahmanagama, Polgasowita Road, Kirigampamunuwa and Kudamaduwa — from 8:00 p.m. on April 6 to 8:00 a.m. on April 7.

Production at the Labugama and Kalatuwawa water treatment plants has been constrained by falling feeder-reservoir levels, the board said. Both plants supply parts of the Colombo district outside the city’s core network, which the NWSDB last week confirmed would not face cuts during the April 11–14 Avurudu period.

The latest restrictions are concentrated in suburbs that draw from the southern reservoir cluster, leaving central Colombo unaffected for now. The Meteorological Department has forecast normal rainfall for May–June but expects continued heat-index warnings into mid-April, suggesting further localised cuts in suburban supply zones if dry conditions persist.
