It was a source of national pride – technology and discipline besting a crippling lack of water.

But four years of drought have overtaxed Israel's unmatched array of desalination and wastewater treatment plants, choking its most fertile regions and catching the government off-guard.

The Sea of Galilee, technically a lake near the border with Syria, is forecast to hit its lowest level ever before winter rains come, despite the fact that pumping there was massively reduced. Underground aquifers, the other main freshwater source, are nearing levels that will turn them salty.

How to cope with the crisis is becoming an increasingly touchy subject in Israel. Proposed cuts to water use for the coming year, more than 50 percent in some areas, prompted vehement opposition from farmers, who already face tough restrictions and would have been the hardest hit. The government quickly backtracked.

In the Middle East, one of the most vulnerable regions to climate change, water is also the subject of wider tensions. Intense pressure on already scarce water resources could lead to an increase in migration and the risk of conflict, the World Bank has warned.

Palestinians have long complained of inadequate access to water, which is mostly under Israeli control in the West Bank. Israel has said it has supplied more water than required under interim peace deals.

Under discussion for a possible long-term solution to Israel's water problem is the construction of an additional desalination plant, an industry official said. A similar facility in Israel has cost more $400 million.

Several new reservoirs to catch rain and flood waters could also relieve some pressure as a quick, $60 million fix, the official said, asking to remain anonymous due to the political sensitivity of the subject.

Just a few years ago Israel, a country two-thirds arid, declared an end to the water shortages that hounded it for decades. A longstanding nationwide awareness campaign ceased and Israelis could take long showers and water their gardens.

Supply issues are being hardest felt among farmers in the northern tip of Israel, the region where Dubi Amitay, a fourth-generation farmer and president of the Israel Farmers Federation, lives.

Amitay said the shortage had made him decide to dry out 3,700 acres of land, which will take a toll on future harvests.

His home region of eastern Galilee, a lush swath of land between the coast and the Golan Heights, could lose up to NIS 500 million this season, he said.

The lack of reliable waters supply leaves farmers with deep uncertainty.

"Will we have water or not?" he wondered.
