Sustainable Asset Valuation of Wastewater Treatment Infrastructure in South Africa

An integrated assessment of infrastructure solutions for reducing nutrient-related pressures in the Hartenbos estuary

The results of this assessment provide an overview of the societal costs and benefits of different water treatment options, considering outcomes for citizens, businesses, Mossel Bay Municipality, and the Western Cape Government. The comparative valuation provides several insights. Examples of research questions include: how efficient are the different technologies for treating the wastewater, and what contribution would they provide to the water quality of the Hartenbos estuary? Do the different options comply with national water quality standards? What would be the direct and indirect economic outcomes of improving water quality and recycling water? These questions (and more) are answered in this SAVi assessment.
