Municipal spokesman Cecil Mbolekwa said: “The municipality discovered that there are traces of colour in our water supply. The municipality embarked on an investigation to get to the root cause of this.
“The contamination has been caused by low water levels at the Sarel Hayward dam as they are at 50%. If the water levels are below 60% they are subjected to contamination with sand. This prompted the municipality to increase the dosages as to improve water quality. The Amatola Water was requested to assist with the adjusting of the dosage.
“The colour has since improved after the dosage was changed. Constant monitoring will be done by the municipality.”
