Israel has received bids from three groups interested in the construction and operation of desalination plants, which will supply water to the country's fifth-largest household and help address possible shortages caused by climate change.
Israel's Ministry of Finance said on Thursday that the plant will be the world's largest factory using reverse osmosis technology and will join the unparalleled ranks of five desalination plants already spread across the Mediterranean coast of the country.
In last November, the state issued a tender document saying the system was overwhelmed by five years of low rainfall.
The seventh factory is still being planned.
The director of the Israeli water authority said the increase would help ensure Israel's "ability to supply water based on climate change affecting our region ".
Bids have been received for the IDE technology and remember Water Company (Hutchison Water) in Israel, as well as partners from Afcon, Acciona and JVC.
The finance ministry said the European Investment Bank had said it would provide up to 0. 15 billion euros to help finance the project.
The facility will produce about 0. 2 billion cubic meters of water each year in the Soreq area in central Israel.
85% of household and municipal water will come from seawater desalination
once it goes online.
The tender also includes the option to build a private power plant of 150 MW.
The Treasury did not say when a final decision would be made, but it expects construction to begin in 2020 and will take three years.
The purpose of the tender is to provide 25 years of funding, construction and operation for the plant.
