The Lesotho Highlands Water project is 40 years old and going strong: but history weighs on its successes

Published on March 30, 2026

The Lesotho Highlands Water Project (LHWP), a major infrastructure initiative that has been supplying water to South Africa for four decades, marks its anniversary amid mixed reflections on its legacy. Originally conceptualized during the apartheid era, the project has been a source of both development and contention, with its history casting a long shadow over its ongoing successes.

Officially launched in 1986, the LHWP was designed to harness the abundant water resources of Lesotho to benefit South African cities, particularly in the Gauteng province. The system of dams, tunnels, and aqueducts has drawn millions of cubic meters of water across the border each year, supporting urban growth in South Africa while providing a steady revenue stream to the economically challenged nation of Lesotho.

However, the deal was struck without the kind of public consultation that many would now deem essential for such a transformative project. Critics argue that the lack of transparency and local input during its inception has led to a sense of disenfranchisement among the very communities whose lands were affected developments.

The government of Lesotho has historically faced challenges balancing the economic benefits derived from the water sales with the societal implications for its citizens. Many local residents have experienced displacement from their homes, land loss, and disruption of their agriculture-based livelihood. The project has also sparked ongoing discussions about environmental preservation and the fair distribution of resources.

While the LHWP has generated significant financial returns for Lesotho, constant disputes over revenue sharing and equitable compensation have emerged. The economic gain has not always translated into improved living conditions for the population, leading to frustrations among various stakeholders. Activists continue to call for a more inclusive approach to governance and the better management of resources in future projects.

One of the critical achievements of the LHWP is its role in fostering regional cooperation between Lesotho and South Africa. Properly harnessed, water can serve as a powerful bridge between nations, and the LHWP remains a prime example of how shared resources can cultivate interdependence. Both nations continue to rely on the project for water security, which has become even more crucial in the face of climate change and growing water scarcity issues.

As the LHWP moves into its fifth decade, the need for transparent governance and community engagement has never been more urgent. Policymakers and stakeholders are tasked with addressing the historical grievances while ensuring that the project evolves to meet contemporary needs. How they navigate these challenges will determine the sustainability of the project and its impact on future generations.

The Lesotho Highlands Water Project stands as both a symbol of potential and a cautionary tale of the complexities that arise from large-scale development initiatives. Reflecting on the past can offer guiding lessons for an equitable and collaborative future, ensuring that all voices are heard in the ongoing dialogue about how best to manage shared resources.
