Israel Loses 5 of 6 Desalination Plants as Gaza Sewage Fears Deepen Water Crisis
3 articles · Updated · The Washington Post · Sep 4
Summary
Five of Israel’s six desalination plants went offline this week after microalgae clogged Mediterranean intake pipes, pushing authorities to ration water for agriculture and tap the Sea of Galilee and reservoirs.
Israeli experts said the bloom drifted north from Egypt’s Nile delta, while untreated sewage from Gaza likely fed and intensified it; Mekorot cited high seawater temperatures and declined to address Gaza’s role directly.
UNICEF said all six of Gaza’s wastewater treatment plants are shut and 70% of sewage pumping stations are out of service, with 10.6 million gallons of wastewater discharged into the sea each day untreated.
The episode exposed how Gaza’s sanitation collapse is spilling across the border: Gazans face contaminated water and illness, while Israeli environmental advocates say repairs to Gaza’s sewage system have become a public-health imperative for both sides.
Water on the Brink: The 2026 Israel-Gaza Algal Bloom Crisis and the Fragility of Desalination-Driven Security
Overview
In late August 2026, Gaza’s destroyed wastewater plants led to over 130,000 cubic meters of raw sewage flowing daily into the Mediterranean. Carried north by marine currents and fueled by climate-driven warmer waters, this sewage triggered a massive microalgal bloom near the Nile Delta. The bloom caused extreme turbidity, forcing most of Israel’s desalination plants offline and sparking water shortages, agricultural losses, and emergency measures. Authorities responded with groundwater pumping and controversial chemical spraying, but public health and environmental concerns grew. The crisis exposed how regional conflict, climate change, and shared water systems create deep interdependence and vulnerability across borders.
