uMngeni-uThukela Water (UUW) is pleased to report a significant improvement in the removal of 2-Methylisoborneol (2-MIB), the compound responsible for the earthy and musty taste and odour that has affected portions of the water supplied to the eThekwini Metro in recent months.
Through our interventions, we have managed to remove over 70% of 2MIB from the water.
The elevated 2-MIB levels originated from algal activity in Inanda Dam and impacted the quality of raw water supplied to the Wiggins Water Treatment Works for treatment and distribution. While algal counts in the dam remain above acceptable levels, the extensive optimisation of treatment processes initiated in May 2026 is now delivering measurable results.
Recent water quality analyses indicate that 2-MIB concentrations in treated water have consistently reduced to levels at, or below, the human odour detection threshold. This represents a major milestone in UUWโs efforts to address the taste and odour challenges experienced by consumers.
The improvement has been achieved through the implementation and optimisation of advanced treatment processes at the Wiggins Water Treatment Works, supported by intensified monitoring and operational interventions. These measures have significantly enhanced the plantโs ability to manage fluctuating source water quality conditions associated with algal blooms in Inanda Dam.
UUW recognises the inconvenience caused to consumers during this period and appreciates the patience and understanding shown by affected communities while these interventions were being implemented.
Although the current results are encouraging, UUW will maintain its enhanced treatment regime and continue to closely monitor water quality conditions within the dam and throughout the treatment process. In parallel, the organisation is pursuing catchment management interventions aimed at addressing the underlying causes of excessive algal growth and reducing the likelihood of future taste and odour events.
UUW remains committed to providing safe, reliable, and high-quality drinking water to all customers and will continue to invest in both operational and long-term solutions to safeguard water quality across its supply system.
