Report Coverage
This report examines key trends shaping South Africa’s water supply sector, with a focus on water availability and security, demand and consumption patterns, access to water services, water quality, infrastructure capacity and condition, and supply reliability. It considers the contribution and performance of the country’s major water sources and supply systems, including surface water, groundwater, bulk water infrastructure, and alternative sources such as reuse and desalination, as well as the effects of drought, climate variability, population growth, urbanisation, and economic activity on supply and demand. The report also assesses infrastructure investment, maintenance backlogs, non-revenue water, and municipal distribution challenges, along with policy, regulatory, and institutional developments influencing the sector. It concludes with an assessment of opportunities, emerging risks (including the 2026/27 El Niño), and the outlook for water security and supply through 2031. As a trends-focused publication, the report differs from the standard WOW industry report format and does not include company profiles.
Introduction
• A reliable water supply is essential to public health, economic activity, food security and environmental sustainability.
• In South Africa, however, water security is under pressure from challenges in resource management, infrastructure condition and service delivery. Water provision and management, together with the condition and performance of wastewater systems, remain important national concerns. Ageing, poorly maintained infrastructure; pollution; inefficient resource management; and weaknesses in municipal service delivery have contributed to unreliable water services and growing pressure on available resources.
• Although access to piped water has expanded, reliability remains uneven, with supply disruptions affecting households and businesses. Population growth, economic activity, climate change and variable rainfall add to these pressures.
• Water stress also poses a material risk to the economy. Agriculture depends on reliable water supplies for crop and livestock production, while mining, manufacturing, power generation, and other water-intensive industries require secure, predictable access to sustain operations. Water shortages and supply disruptions can therefore have wider economic consequences, affecting production, operating costs, food prices, investment decisions and business continuity.
• Drought risk, including that associated with El Niño events, further highlights the need to assess the country’s exposure to climate variability and its preparedness for periods of water shortage.
• The report examines the key trends shaping South Africa’s water sector, with particular attention to water scarcity and climate volatility, the economic exposure of water-dependent sectors, lessons from the 2015/16 El Niño-induced drought, and preparedness for future droughts. It also assesses developments in infrastructure investment, alternative water supplies, water efficiency and technological innovation. The report identifies the principal risks, opportunities and strategic considerations likely to shape the sector through to 2031, providing a basis for informed decision-making by government, industry, businesses and investors.
Strengths
• Engineering expertise: existing technical capabilities support the development, operation and upgrading of water infrastructure.
• Established institutions: DWS, water boards and municipalities provide an institutional basis for managing water resources and services.
• Established policy framework: national legislation and strategies provide a foundation for water-resource management and service delivery.
• Existing bulk infrastructure: dams, transfer schemes, pipelines and treatment facilities support household, agricultural and industrial supply.
• Recognised investment priorities: government plans identify infrastructure renewal, water-loss reduction and alternative supplies as key priorities.
Weaknesses
• Ageing infrastructure: inadequate maintenance and asset renewal increase the risk of failures and service interruptions.
• Constraints on conventional supply: limited availability of economically and environmentally viable sites for major additional surface-water schemes.
• High water losses and non-revenue water: physical losses, metering weaknesses, illegal connections and billing deficiencies reduce available supply and revenue.
• Implementation and financing constraints: challenges in translating infrastructure plans into financed, implemented, operational and adequately maintained assets.
• Uneven municipal capacity: differences in technical, financial and asset-management capacity contribute to inconsistent service delivery.
• Wastewater and water-quality challenges: inadequate treatment and pollution reduce usable water resources and increase treatment costs.
Opportunities
• Digital monitoring and smart-water technologies: smart metering, telemetry, network analytics and predictive maintenance can improve operational performance.
• Diversification of supply: sustainable groundwater development, water reuse, rainwater harvesting and desalination in suitable coastal locations can diversify local supplies.
• Industrial water efficiency and recycling: greater reuse and process optimisation can reduce demand for potable water.
• Network rehabilitation and loss reduction: pipe replacement, leakage detection, improved metering and pressure management can increase effective supply and municipal revenue.
• Note: The suitability of alternative water sources and technologies is location-specific and requires technical, environmental, financial and institutional assessment.
• Private-sector participation: appropriately structured partnerships can mobilise capital, specialist expertise and operational capability.
• Specialised services: demand for monitoring, treatment optimisation, water-quality management and performance-based maintenance can create opportunities for technology providers, engineering firms and infrastructure investors.
• Wastewater treatment and water reuse: treatment upgrades and reclamation can reduce pollution and provide additional supplies for suitable uses.
• Water-efficient agriculture: irrigation efficiency, monitoring and other water-saving technologies can reduce agricultural demand.
Threats
• Broader economic exposure: water shortages can affect agriculture, mining, manufacturing and other water-dependent sectors, with knock-on effects on employment, household finances, investment and credit risk (including banks).
• Climate variability and extreme weather: droughts, floods, heat and rainfall variability can affect water availability, infrastructure and demand.
• El Niño and drought risk: prolonged dry conditions could exacerbate existing water-security vulnerabilities, although impacts will vary according to rainfall and catchment conditions, storage levels and operational preparedness.
• Energy-cost pressures: energy-intensive pumping, treatment and desalination can increase operating costs and limit the viability of some solutions.
• Financial and institutional constraints: poor revenue collection, constrained municipal budgets and limited technical capacity can delay investment and maintenance and undermine service sustainability.
• Infrastructure deterioration: inadequate maintenance and delayed rehabilitation increase failures, losses and service interruptions.
• Pollution: wastewater discharges, agricultural runoff and other contaminants can reduce raw-water quality and increase treatment requirements.
• Project delivery and financing risk: cost escalation, procurement delays and funding constraints can prevent projects from achieving their intended outcomes.
• Rising and competing demand: population growth, urbanisation and water-intensive economic activity (including mining, power generation, manufacturing and data centres) intensify competition for limited resources.
• Uneven reform and implementation: delays in institutional reforms, regulation and project preparation can slow service improvements and weaken investor confidence.
Outlook
• South Africa is one of the world’s most water-scarce countries, and has limited scope to develop additional conventional water resources as much of its economically usable surface water is already developed or allocated.
• Future water security will therefore increasingly depend on improving water-use efficiency, reducing losses, rehabilitating ageing infrastructure, expanding water reuse and sustainable groundwater development, and delivering planned augmentation projects.
• Climate variability, deteriorating water and wastewater infrastructure, pollution, high non-revenue water and municipal capacity constraints will continue to heighten supply, service-delivery and economic risks through 2031.
• These pressures are creating significant opportunities for infrastructure rehabilitation, leakage reduction, wastewater treatment and pollution control, water reuse, alternative supply development, industrial water recycling, climate-resilient infrastructure, and digital water management.
• Progress will depend increasingly on effective implementation, with investment and technology needing to translate into lower water losses, improved drinking-water and wastewater performance, stronger pollution control, more reliable and diversified supply, and greater resilience to drought and flooding.
