Israel Faces Water Crisis Amidst Opaque Management of Desalination Plant Failures

Israel's water supply continues uninterrupted despite a significant crisis affecting its desalination facilities, yet the public remains largely unaware of the measures taken and their potential costs. Five major desalination plants along the Mediterranean coast were suddenly shut down on August 27 due to a severe algal bloom, which continues to disrupt their operations, leaving them functioning at only partial capacity. While authorities initially instructed farmers in southern Israel to dry their fields, this directive was quickly reversed following public outcry. The public, however, has not been informed about how the country is compensating for the reduced desalination output.

Questions submitted by the media to the Water Authority and the Energy Ministry regarding the crisis have been met with incomplete answers. Even after public anger over a secretive, unannounced experiment involving commercial chemicals to combat the algae, a full picture of the situation has not been provided. Among the measures taken was the reactivation of previously closed, and potentially contaminated, boreholes, with the Water Authority failing to disclose which boreholes were used or whether their water poses a risk to drinking quality. Similarly, information on the extent of water being pumped from the Sea of Galilee and its impact on the ecosystem and water levels, especially after a harsh drought, has not been released. The Water Authority stated that past drops in the Sea of Galilee's level below the red line did not cause significant damage and that theories about saltwater intrusion proving incorrect.

Further concerns arise regarding groundwater, particularly the coastal aquifer, where declining water levels threaten water quality. The Water Authority stated that drilling is concentrated in the northern region where groundwater levels are higher, but did not provide data on pumping volumes or level changes. Economically, while the Energy Minister estimated the damage to desalination membranes at several million shekels with minimal impact on the water economy, replacing filters and membranes constitutes a significant portion of desalination plant maintenance costs. The state has pledged to compensate operators, but it remains unclear if membrane replacement will affect water tariffs. The preparedness of desalination plants for such events, including pre-treatment systems for marine pollution, is also unknown.

Despite the reduced desalination capacity, there has been no significant public call for water conservation, with the Water Authority merely requesting "wise use" of water. A government source suggested this lack of transparency and conservation appeal might be politically motivated. The national water infrastructure master plan has been stalled for over a year, and a plan for aquifer rehabilitation, crucial for compensating for desalination shortfalls, has not been developed. This situation highlights a neglect of natural water sources, which are now being over-exploited as the country relies almost entirely on desalination for drinking water. The algal bloom incident has exposed the vulnerability of even these advanced facilities to natural events, with climate change expected to increase the frequency of such blooms, yet Israel lacks a comprehensive plan to address these challenges.
