From Sept 1, Sarawak Water customers can reach a 24-hour call centre at 1-300-88-2020, including on weekends and public holidays. The new line gives households and businesses one central number for customer assistance instead of limiting contact to normal office hours. Sarawak Water has not yet published a full list of the cases handled by the centre or a response-time target. When reporting a supply or premises issue, callers should give the exact location and keep an account or premises reference available if they have one. This helps the operator identify the case and route it without relying on a separate departmental number.
