The National Water Supply and Drainage Board (NWSDB) has announced a 12-hour water supply interruption affecting Colombo and several surrounding areas from 9.00 a.m. to 9.00 p.m. tomorrow (04).
According to the NWSDB, the water cut will affect Colombo 01 to Colombo 15, as well as Battaramulla, Pelawatta, Hokandara, Koswatta, Thalawathugoda, Sri Jayawardenepura Kotte, Rajagiriya, Mirihana, Madiwela, Nugegoda, Nawala, Kolonnawa, IDH, Kotikawatta, Angoda, Wellampitiya, Orugodawatta, Kaduwela, Maharagama, Boralesgamuwa, and Piliyandala.
The interruption is necessary due to the temporary suspension of electricity supply to the Ambatale Water Treatment Plant, enabling essential maintenance work to be carried out at the Mulleriyawa Grid Substation.
In addition, electrical system upgrade work will be undertaken at the Dehiwala Water Pumping Station and the Maligawatte Elie House Pumping Station during the same period.
The NWSDB has advised residents in the affected areas to store an adequate supply of water in advance and use it sparingly throughout the scheduled interruption.
Water supply is expected to be restored gradually once the maintenance work has been completed.
