Sustainable Asset Valuation of Wastewater Treatment Infrastructure in South Africa

This report details a Sustainable Asset Valuation (SAVi) assessment of wastewater treatment infrastructure options for the Hartenbos estuary in South Africa, evaluating their impact on water quality, nutrient loads, and potential for agricultural water reuse.

• Reusing 50% of treated wastewater for irrigation by 2060 could support an additional 330 hectares of agricultural land, enhancing water security, job creation, and agricultural productivity as a climate adaptation measure.
• The economic viability of an artificial wetland option is contingent on its ability to increase biodiversity and habitat quality to attract more tourists; it is the most economical choice when these benefits are included, but the least economical when they are excluded.
• A hybrid solution is the most effective for reducing nutrient pollution, although an artificial wetland could generate higher net benefits if it creates additional tourism revenue.
