A severe algae bloom in the new watercourse built along Kings Beach was caused by a leaking sewage pipeline, which contaminated the water with effluent and e-coli bacteria.
The matter is, however, being addressed according to Humewood and Summerstrand ward Councillor, Dean Biddulph.
Biddulph, who was one of the main drivers of the beachfront upgrade, said the problem started shortly after the heavy rains two months ago. He said following investigations the cause of the algae bloom had been traced to a leaking sewer line which has since been sealed.
He said a microbial product was also being added to the newly built lake to assist in restoring the water quality.
“The microbes will be released into the lake and will consume the nutrients that the algae feed on. Once the nutrient are removed, the algae will die and the microbial treatment will then proceed to break down and consume the dead algae,” he said.
Biddulph said the initial treatment would be implemented over a three month programme.
“Thereafter, the water will receive a monthly maintenance dosage. In addition, a filtration/aeration system has also been agreed to and will be implemented as soon as budget has been identified,” he said.
Biddulph said the delay in starting the treatment protocol was largely due to establishing the actual cause for the contamination and then identifying a suitable treatment.
“Finally proper Supply Chain Management procedures had to be followed in procuring the product for the treatment. The delay is of course regrettable but was unavoidable,” he said.
