Heleen Tshibumbu, specialist journalist and technical writer, speaks to the tech behind smarter wastewater management – level and pressure solutions that make a difference.
Mining has historically played a significant role in the economic development of Africa by providing employment opportunities, infrastructure and social services in remote areas. The industry has contributed to the establishment of roads, schools and healthcare facilities, supporting community development and national economic growth. However, there are notable environmental challenges associated with mining activities, particularly in the management of wastewater, such as acid mine drainage( AMD), which can have substantial impacts on water resources and ecosystems.
Large quantities of acidic water can end up in the environment during mining activities, initially into groundwater and ultimately into streams and rivers. The consequences of AMD are multifaceted. Contaminated water supplies pose direct health risks to local populations, as heavy metals and low pH levels render water unsafe for consumption and agricultural use. Ecosystems suffer too as aquatic life struggles to survive in altered pH conditions, leading to
reduced biodiversity.
Effective management of wastewater Despite these challenges, sustainable mining practices offer a pathway to mitigate environmental impacts while maintaining economic benefits. Central to this approach is the effective management of wastewater generated during mining operations. Implementing advanced monitoring and treatment systems can prevent the release of harmful contaminants into the environment. Accurate measurement of water levels, flow rates and chemical compositions is essential for the efficient operation of treatment facilities and the prevention of accidental discharges.
