The Water and Sewerage Authority (WASA) says it is taking immediate and sustained action to address reports of discoloured water affecting customers in some areas.
In a media release on Thursday, the Authority said technical, engineering, water quality and field teams were monitoring the situation, identifying contributing factors and implementing measures to resolve the issue.
WASA assured customers that the water remained safe for domestic use, adding that daily water quality testing continued at major facilities in keeping with World Health Organisation standards and applicable water quality requirements.
The Authority said the tests formed part of its ongoing monitoring and quality assurance measures.
It acknowledged that changes in the appearance of the water could cause concern and inconvenience to customers, and said it was taking those concerns seriously.
WASA said restoring the water supply to its normal appearance was a priority and that every effort was being made to resolve the situation as quickly as possible.
