Sustainable Asset Valuation of Wastewater Treatment Infrastructure in South Africa

The report evaluates wastewater treatment options for the Hartenbos estuary, finding that while a hybrid solution is most effective at reducing nutrient pollution, an artificial wetland offers the highest net benefits if ecological and tourism gains are included. It also highlights that reusing 50% of treated wastewater for irrigation by 2060 could support 330 additional hectares of agricultural land, enhancing water security and job creation.

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