KwaNomzamo WWTW upgrade to be completed in August 2025

Humansdorp – The KwaNomzamo Waste Water Treatment Works (WWTW) in Humansdorp, poised to benefit over 2 200 households, is nearing completion following a substantial R49 million upgrade.

Despite the challenges posed by abnormal weather conditions and heavy rainfall – which resulted in construction delays – the project, originally scheduled for completion in May this year, is now expected to be finalised by August 2025.

Originally allocated a Municipal Infrastructure Grant (MIG) budget of R42.36 million, the project costs escalated to R49.32 million due to unforeseen additional civil works, including security fencing to combat vandalism and refurbishments of reactors and clarifiers.

The upgraded WWTW – with a treatment capacity of 2.5 million litres per day –  will serve Boskloof, Panorama, Mat Melville, Humansdorp Central, and the Industrial Area. 

Executive Mayor Hattingh Bornman said the WWTW plays a vital role in the community for several reasons.

“It is vital for infrastructure development because it is designed to support the KwaNomzamo 400 housing project, addressing housing demands in the rapidly growing community. Furthermore, by incorporating advanced treatment technologies, the facility contributes to better sanitation and hygiene, directly impacting residents' quality of life.

“In addition, the project represents a significant investment in the community's future, aligning with goals of reliable infrastructure and fostering growth.”

Scope of work

The project aims to not only increase the treatment capacity of the plant, but also to remove impediments hindering the progression of the KwaNomzamo 400 housing project.

The scope of work includes among others secondary settling tank equipment, pump station equipment, chlorine dosing equipment, return activated sludge
(RAS) pump station, chlorine contact tank, and interconnection pipework.

It, furthermore, includes the refurbishment of the bridge structure and the reinstatement of the sludge dewatering belt press.
