Wastewater Management

Wastewater is one of the most significant and growing threats to South Africa's water resources. The discharge of inadequately treated effluent from municipal wastewater treatment works, industrial facilities, and mining operations into rivers, wetlands, and groundwater systems has reached crisis levels in many parts of the country, contributing to widespread water quality degradation, ecosystem damage, and public health risks. South Africa's wastewater crisis is driven by a combination of ageing and under-maintained infrastructure, inadequate operational capacity at many treatment facilities, rapid urbanisation, and insufficient regulatory enforcement.

Effective wastewater management – encompassing treatment, reuse, monitoring, and regulation – is essential for protecting South Africa's scarce freshwater resources, meeting the ecological Reserve requirements of the National Water Act, and safeguarding the health of downstream communities and ecosystems. It is also increasingly recognised as an opportunity: treated wastewater is a reliable, drought-independent water source that can contribute meaningfully to water security if managed appropriately.

The WRO addresses wastewater management across three distinct sectors, each with its own sources, regulatory framework, treatment challenges, and research priorities. Select a sub-page below to explore resources relevant to each sector.
