Israel has faced mounting water security challenges driven by climate change, population growth, and a heavy reliance on desalination. Water Authority Director Yehezkel “Hezi” Lifshitz previously characterized desalination plants as the “Iron Dome of the water sector” due to their critical role in offsetting low precipitation levels.

This reliance became a point of vulnerability when most of the country’s desalination plants were forced into emergency shutdowns due to high seawater turbidity and pollution. The disruption affects facilities providing approximately 80 percent of Israel’s fresh water. Preliminary assessments suggest the turbidity may be caused by a large drift of microalgae, potentially originating from the Nile region in Egypt.

Recent reports indicate that the algae proliferation was intensified by large quantities of untreated sewage being discharged into the Mediterranean from the Gaza Strip, following the destruction of wastewater treatment plants and sewage pipelines. The collapse of Gaza’s drainage and sanitation systems has created a dual humanitarian and ecological crisis.

New developments confirm that microscopic algae from the Nile Delta have caused significant disruptions to desalination infrastructure in both Israel and Egypt. In Israel, five out of six major private desalination plants—including facilities in Ashkelon, Palmachim, Sorek A, Sorek B, and Ashdod—were forced to shut down. While these facilities have since resumed operations, most continue to run at partial capacity. This has led to strict water conservation alerts in municipalities such as Jerusalem and forced agricultural cutbacks in the Negev region. In Egypt, the Kilometre 17 plant in North Sinai also shut down, threatening the drinking water supply for hundreds of thousands of residents.

## Claims

- Five of Israel's six major desalination plants were forced offline due to an algal bloom. (corroborated by 8 sources)
- Untreated sewage from the Gaza Strip is suspected of providing nutrients that accelerated the algal bloom. (corroborated by 7 sources)
- The lack of fuel and spare parts for generators threatens the operation of hospitals and water pumps in Gaza. (corroborated by 4 sources)
- The Israeli National Water Company, Mekorot, increased water extraction from Lake Tiberias and local reservoirs to compensate for the shortage. (corroborated by 4 sources)
- Satellite imagery indicates the algae bloom originated in the Nile Delta and moved east via sea currents. (corroborated by 4 sources)
- The algal bloom reduced Israel's desalinated water supply by approximately 80 percent. (corroborated by 4 sources)
- The mass microalgae bloom in the Mediterranean is an extremely rare event, unseen for at least two decades. (corroborated by 3 sources)
- Authorities implemented water restrictions for agriculture and public landscaping in southern Israel. (corroborated by 3 sources)
- All six wastewater treatment plants in Gaza have been knocked out of service. (corroborated by 2 sources)
- Approximately 90 percent of Gaza's population is experiencing medium to high water insecurity. (single source)
- People in Gaza have access to an average of just 4.5 liters of drinking water per person each day. (single source)
