Background

This programme was initiated by the Roads and Stormwater department in the eThekwini Metropolitan Municipality to prevent damage to infrastructure caused by waste and alien vegetation (e.g. the blockage of culverts). Working with 11 other city departments, it aims to address the twin challenges of unemployment and environmental pollution.

Approach

The programme involves cleaning watercourses and maintaining them to allow them to flow freely. The regular removal of waste and overgrowth prevents future blockages. During a major flooding event in April 2022, areas where the TRMP is operational experienced less damage to infrastructure than those where the programme is not implemented. The programme focuses on highly polluted rivers and streams in low-income, high-density settlements. Local ownership is fostered by employing cooperatives from local communities.

Environmental Impact

Ecosystem health is improved by removing alien species, which normally crowd out native species. Removing pollution and blockages helps to improve water quality and reduce flooding.

Success Factors

Collaboration across city departments who were able to pull resources together is key to the success of the programme. Funding from external organizations has helped to upscale the programme and create a business case.
