South Africa- The Lesotho Highlands Water Project (LHWP) stands as a testament to the power of collaborative efforts between nations. Conceived as a multi-phased initiative between Lesotho and South Africa, its primary goals encompass addressing the pressing need for a dependable water supply to South Africa’s densely populated Gauteng region and contributing to Lesotho’s energy requirements through hydro-electricity generation.
At the core of this ambitious venture lies the creation of intricate infrastructure, including tunnels and dams, strategically designed to redirect water from the Lesotho mountains to South Africa. This joint endeavor represents one of the most substantial and impactful infrastructure projects in the region, ensuring water security and sustainable development for both nations.
Securing the necessary funding for such a colossal undertaking is no small feat, and a variety of stakeholders have come forward to support the LHWP. The African Development Bank (AfDB) has been instrumental, extending a significant loan of ZAR 1.3 billion during Phase II of the project. Additionally, the New Development Bank (NDB), dedicated to financing sustainable development projects, collaborated in financing the LHWP through a ZAR 3.2 billion loan agreement inked during the 2023 BRICS Summit.
The significance of the LHWP transcends beyond mere water supply and hydro-electricity generation. It emerges as a strategic response to challenges posed by a growing population, rapid urbanization, economic activities, and the impacts of climate change. By addressing these challenges, the LHWP establishes itself as a cornerstone for developing water infrastructure capable of meeting both current and future demands.
As construction advances, the LHWP becomes a catalyst for job creation, with the awarding of contracts for Phase II marking a pivotal milestone. This not only represents a source of approximately 5000 job opportunities over a three-year period in both Lesotho and South Africa but also carries the potential to create and sustain over 5,500 new jobs during the operational phase of the project.
The impact of the LHWP extends beyond infrastructure development, serving as a beacon for regional integration and economic growth. It nurtures a relationship between South Africa and Lesotho that is deeply intertwined socially and economically. The water delivered by the project stands poised to enhance water availability in the greater Gauteng region, addressing needs for domestic consumption, irrigation, industries, and mining.
On the Lesotho side, over 85,000 people stand to directly benefit from the project upon its completion. The positive repercussions on community development, private sector growth through improved infrastructure, and contributions to Lesotho’s socio-economic development are substantial.
Looking forward, the LHWP is not confined to being a mere water transfer project; it unfolds as a comprehensive strategy to meet the dual needs of water supply and energy generation. The culmination of Phase II, marked by the construction of the Polihali Dam and Polihali Transfer Tunnel, signifies a significant stride towards realizing these objectives. The dam, characterized by a concrete-faced rockfill structure, will form a reservoir on the Senqu and Khubelu rivers, while the transfer tunnel will facilitate the efficient movement of water from the Polihali reservoir to the Katse reservoir.
As the LHWP progresses towards its slated completion in 2028 for water transfer and 2029 for hydropower generation, it emerges as a model for sustainable development. It not only addresses the evolving needs of nations but also exemplifies cooperation and mutual benefit between Lesotho and South Africa. The LHWP transcends being a mere project; it stands as a transformative force shaping the future of water and energy in the region.
