The analysis finds that investing in nature-based infrastructure (NBI) in Drakenstein, South Africa, can reduce flood damages by up to USD 36 million against costs of USD 8.65 million over 25 years. The study indicates a benefit-cost ratio of up to 5:1 (ZAR 5 return for every ZAR 1 invested), with net benefits reaching ZAR 600 million (USD 34.2 million). These benefits include avoided flood damages, job creation, and improved mental health, with NBI proving most valuable in climate scenarios characterized by frequent and intense floods.

A buyback centre in Vrygrond, Cape Town, diverts approximately 1,500 tonnes of waste from landfills annually, providing an annual community income between R950,000 and R1.9 million. The centre employs 20 people and supports 300 waste reclaimers, though it faces challenges regarding land access and infrastructure. The document recommends formalising engagement between the municipality and buyback centres to improve waste management in informal areas.

The Berg Water Management Area is a constrained system where water requirements are projected to exceed yield by 2019. A hydro-economic analysis indicates that by 2040, the water supply deficit could cost the region over R146 billion and nearly 650,000 jobs annually, with the City of Cape Town bearing the highest opportunity costs. The report identifies systemic failures in current top-down planning and financing, recommending the establishment of a Regional Water Utility and the use of multi-criteria decision tools to prioritize 'smart' water use over first-come, first-served allocations.

The document analyzes water demand in the Berg WMA, highlighting that climate change will increase the water requirements of key crops like grapes, stone fruit, and citrus. It identifies a significant future water supply deficit, particularly in the municipalities of Swartland, Stellenbosch, and Drakenstein, and argues that the low economic 'value per drop' of agriculture compared to urban use will make securing additional water allocations difficult. The report recommends crop switching to low-water, high-value alternatives and investing in water efficiency technology to mitigate these risks.

The Drakenstein Municipality faces significant water constraints due to urban growth and climate change, with urban water requirements projected to grow by 129% by 2040. Agriculture, particularly grapes which consume 80% of irrigated water, is a major driver of demand. By 2040, the estimated water deficit could cost the local economy approximately R10.5 billion per annum and 57,218 jobs.

The document warns that Stellenbosch Municipality faces a severe water deficit by 2040, driven by high urban growth and the water-intensive nature of its agricultural sector, particularly grape production. This deficit is projected to cost the local economy R10.3 billion per year and result in the loss of 56,602 jobs. Climate change is expected to further increase agricultural water requirements by 38% by 2040. The report recommends that the municipality decouple population growth from water consumption through conservation and demand measures to mitigate these risks.

The Swartland Municipality faces significant water scarcity risks by 2040, driven by high population growth and the water-intensive grape industry. Projections indicate a potential water deficit of approximately 50 million m3 per year by 2040, which could cost the local economy R12.8 billion annually and result in the loss of 68,091 jobs.

The Bergrivier Municipality faces significant economic risks due to high water intensity in its key sectors, particularly agriculture. Projections indicate that changing climatic conditions and population growth will increase water requirements by 2040, potentially leading to a water deficit that could cost the local economy R3.1 billion and 16,229 jobs per annum.

The Berg Water Management Area (WMA) faces a projected water supply deficit of approximately 300 million m3 per year by 2040, which could cost the region over R146 billion and 650,000 jobs annually. Current planning systems are fragmented, treating water and economic development as independent variables, and local municipalities often lack the capacity to secure off-budget financing for infrastructure. The brief recommends that the Western Cape Government support municipalities in integrating water planning into Integrated Development Plans (IDPs), advocate for a regional water utility, and employ hydro-economic modelling to prioritise interventions.

The report examines the transition of South Africa's waste sector from a landfill-centric model to a sustainable waste economy. It highlights a significant gap between current recycling rates (approximately 10%) and the potential resource value of R17 billion that could be unlocked through full recycling. In the Western Cape, the report identifies key opportunities in recyclables, organics, e-waste, and construction and demolition waste, while noting that municipal financial constraints necessitate public-private partnerships to achieve a 20% waste diversion target by 2019.

The South African waste sector is transitioning from a landfill-centric model to one focused on waste diversion, driven by regulatory reforms and limited landfill airspace. While only 10% of waste is currently recycled, significant opportunities exist in the recovery of paper, plastics, glass, e-waste, and construction and demolition waste. In the Western Cape, the City of Cape Town generates 70% of the province's waste, presenting a concentrated market for alternative treatment. Waste-to-energy (WtE) projects face economic and regulatory hurdles, such as low landfill gate fees and electricity prices, but opportunities remain in small-scale biogas and large-scale REIPPPP projects. The report also highlights the role of Producer Responsibility Organisations (PROs) and the availability of green manufacturing incentives in Special Economic Zones like Atlantis.

The document argues that solar PV installations on packhouses are financially viable, particularly for larger systems, due to high daytime energy needs for cooling. It provides a model of financial feasibility and four case studies demonstrating electricity cost reductions and CO2 emissions avoidance. The brief also outlines the regulatory and technical requirements for feeding excess electricity back into the grid within various Western Cape municipalities.

The report analyzes the South African waste sector, which is worth approximately R15 billion and employs 29,000 people. It highlights the Western Cape's higher recycling rates (14%) compared to the national average (9.8%) and examines various waste streams, including plastics, paper, glass, metals, e-waste, and construction and demolition waste. The document identifies significant barriers to waste-to-energy (WtE) projects, such as complex municipal procurement processes and regulatory hurdles, while outlining potential for biogas generation from agricultural and organic waste. It also details GreenCape's initiatives, such as the Western Cape Industrial Symbiosis Programme (WISP), to promote a circular economy.

The South African waste economy, valued at R15.3 billion, is transitioning from 'end of pipe' to 'cradle to cradle' solutions under the National Environmental Management: Waste Act. While the recycling rate stands at 19.6%, the sector faces significant hurdles in municipal procurement, feedstock security, and legal authorisation backlogs. In the Western Cape, municipalities like Cape Town, Drakenstein, and Stellenbosch are pursuing waste-to-energy and organic waste treatment to address critical landfill airspace shortages, with some landfills estimated to have less than 3 years of capacity remaining.

The South African waste economy is valued at R15.3 billion, representing approximately 0.51% of GDP. While the National Environmental Management: Waste Act (NEM:WA) has shifted the sector toward 'cradle-to-cradle' solutions, developers face significant hurdles, including complex municipal procurement processes, long legal authorisation backlogs, and difficulties in securing long-term feedstock agreements. In the Western Cape, limited landfill airspace—with some sites having less than three years of capacity—is driving a need for decentralized waste-to-energy and recycling projects.

The document outlines the opportunities and regulatory requirements for private sector engagement in South Africa's water sector. It highlights a significant infrastructure investment gap, with an estimated R900 billion needed over the next decade. Key opportunities are identified in metropolitan municipalities, where R54.6 billion is planned for water and sanitation spend between 2023/24 and 2025/26. The guide details the roles of national and local government, the impact of new legislation like the Public Procurement Act (2024) and the NWRIA Act (2024), and the specific procurement thresholds and B-BBEE scoring systems used in public tenders. It also lists innovation platforms and trial mechanisms for new technologies.

The document assesses the potential for Western Cape businesses to leverage time-of-use (TOU) tariffs through BESS arbitrage, comparing the repurposing of existing systems against new installations. It finds that while upgrading existing BESS offers high internal rates of return (IRR), new installations are more sensitive to tariff escalation rates and investment horizons, with a 15-year outlook generally improving financial performance.

The document analyzes the alignment of water services by-laws in Western Cape municipalities with the 2005 Department of Water Affairs and Forestry (DWAF) model by-law. It identifies gaps in regulatory clarity, highlights specific business risks such as industrial effluent permits and water audits, and notes that municipalities with more recent updates generally provide better certainty for investors and operators.

The report argues that solar PV is highly suitable for packhouses because their peak energy demands for cooling and packing align with daytime solar generation. Through modelling an apple packhouse, the report finds that large-scale systems (500 kWp) are consistently profitable across various tariff and financing scenarios, while smaller systems (≤10 kWp) require favourable financing to be viable. It emphasizes that the primary value is derived from replacing expensive grid electricity rather than selling excess power back to the grid, which offers lower returns. The report also identifies regulatory hurdles, noting that feed-in tariffs are only available in specific Western Cape municipalities.
