IFC plans $47 million loan to upgrade Johannesburg’s water infrastructure

International Finance Corporation (IFC) is considering a R750 million ($47 million) loan to the City of Johannesburg to upgrade critical water infrastructure, as South Africa’s economic hub struggles with worsening supply shortages and aging systems.

The proposed 15-year financing will fund key upgrades across reservoirs, pipelines, and distribution networks, targeting inefficiencies that have pushed non-revenue water losses to about 45%. The initiative highlights growing reliance on development finance to stabilize urban infrastructure across South Africa.

Tackling water security challenges

Located in Gauteng Province, Johannesburg serves as a key commercial engine for both South Africa and the broader region. However, its water sector has faced growing strain, including recurring supply disruptions linked to constrained bulk supply from Rand Water and aging infrastructure.

The IFC-backed program is designed to address these challenges by reducing system losses and improving service delivery. Non-revenue water, currently estimated at about 45%, is a major concern, with planned interventions focused on systematic pipe replacement and expanded metering to curb leakages and inefficiencies.

Driving long-term resilience

The investment forms part of a broader municipal water capital expenditure plan valued at 1.70 billion rand for FY2025/26 and 1.96 billion rand for FY2026/27. By upgrading aging infrastructure and expanding capacity, the city aims to strengthen water security while supporting future population and economic growth.

Beyond immediate improvements, the initiative is expected to enhance the financial sustainability of the water utility and serve as a model for other metropolitan areas across South Africa seeking to modernize water systems and improve demand management.

IFC’s strategic role

IFC’s proposed loan stands out for its long tenor and local currency structure, features that are typically scarce in commercial financing for infrastructure projects of this scale. The institution also plans to provide advisory support under its Cities initiative, focusing on strategic planning and procurement improvements, in collaboration with other development finance institutions.

The project, classified under IFC’s environmental category B (limited risk), underscores the growing role of development finance in addressing Africa’s urban infrastructure gaps while promoting sustainable and efficient service delivery.
