Kouga Local Municipality is currently undertaking a R4.89 million upgrade of the Hankey Waste Water Treatment Works (WWTW), with the goal of improving the plant’s operational efficiency and strengthening on-site security.
Construction commenced in August 2024 and is expected to be completed by August 30, 2025.
Kouga Executive Mayor, Hattingh Bornman, said, “This upgrade will ensure that the Hankey WWTW operates optimally and can continue to serve the community effectively for years to come.
“We are committed to investing in the essential services that form the foundation of a thriving municipality.”
Scope of Work
The scope of the project is extensive and includes several key interventions to improve functionality and ensure long-term sustainability.
As part of the upgrade, a new open channel flowmeter will be installed at the inlet works to improve the accuracy of flow measurement and monitoring. The existing floating vertical shaft surface aerators will be refurbished to enhance the biological treatment process, while analytical equipment will be supplied and installed to enable better control and management of the aerators.
Clarifiers, which play a critical role in separating solids from treated water, will undergo a full refurbishment.
The Return Activated Sludge (RAS) pump station, and the Supernatant Return pump station will also be refurbished to improve the recirculation of sludge and ensure reliable operation throughout the treatment process.
To enhance disinfection and water quality, a new Sodium Hypochlorite dosing plant will be designed and installed. In addition, a new low-voltage Motor Control Centre (MCC) and a Programmable Logic Controller (PLC) system will be supplied and installed to automate and modernise the facility’s operations.
Finally, minor building works will be undertaken, and new perimeter fencing will be installed to strengthen security at the plant.
“This project addresses the plant’s operational shortcomings, as well as strengthening the security measures on site, ensuring that our infrastructure remains protected and resilient,” said Bornman.
