An unprecedented algal bloom temporarily shut down major Mediterranean desalination facilities. Mekorot rerouted water through alternative wells and reservoirs, leaving the domestic public with virtually no shortage at the tap. Barak Graber, Acting CEO of Mekorot Development & Enterprises, said the episode showed why water security depends on a connected system, not desalination technology alone.
Redundancy During a Disruption
Mekorot combines desalination, recycled wastewater, groundwater and surface water in a single national grid. When the algal bloom disrupted a significant portion of Israel’s desalination capacity, centralized management and routing let the company redirect supply in real time. The public, Graber said, barely noticed a difference.
Graber described desalination as an exceptional solution, but warned that relying on it without system redundancy and intelligent centralized management creates a dangerous vulnerability. Alternative wells and reservoirs provided other supply routes during the disruption. The domestic public experienced virtually no shortage at the tap during the event.
The episode also formed part of the article’s broader discussion of crisis management and resilience. Its questions addressed how centralized management and routing from reservoirs, wells and the national grid prevented a system breakdown while desalination facilities were temporarily offline. The account didn’t identify the algal bloom’s cause or give a calendar date for the disruption; it said the event occurred over the past month.
A National Grid and Regional Links
Graber said water management requires a framework that extends beyond technology. In his account, the climate crisis in the Middle East is a daily reality, and water requires cooperation despite political and ideological divisions.
He also described Mekorot’s capacity to supply high-quality, continuous water to neighbors and build regional partnerships. The article called those links positive mutual interdependence anchored in physical infrastructure, and raised questions about how supplies to neighbors and regional agreements, including agreements signed in the Gulf, could contribute to regional stability. It didn’t give further details about the agreements or the specific water supplies involved.
Mekorot’s operating experience also underpins an international presence, Graber wrote. The company exports operational know-how across Latin America, Europe, Central Asia, India and other locations. Its work includes leak detection, engineering consultancy and master planning. The article asked what makes this expertise attractive to governments and international organizations, but gave no separate answer beyond describing those services and the company’s experience.
Partnerships and Future Water Challenges
Graber said multilateral partnerships linking Mekorot’s operational expertise with private and governmental sectors are key to addressing the global water crisis. He said cooperation could turn water from a flashpoint of conflict into a catalyst for regional stability, development and growth.
The article’s questions also addressed how state-owned enterprises, private companies, international organizations and diplomats could collaborate on water challenges in arid regions. Graber looked to the next decade for such partnerships, without specifying calendar years. The article presented integrated management, supply alternatives and cooperation as central themes in its account of water resilience.
