Water supply to the areas of Moratuwa, Panadura, Borelesgamuwa, Kesbewa, Piliyandala and Horana has been restricted today, the National Water Supply and Drainage Board (NWSDB) said.

The NWSDB said water supply was disrupted due to fuel contamination at the Kalu Ganga, after a bowser carrying fuel toppled over, spilling fuel into the water.
