Electricity generation facilities use huge amounts of water, especially for cooling purposes. For example, the Rutenberg coal power station in Ashkelon requires 330 thousand liters of sea water per hour when it is working on full capacity. Thus, when such a station is working at full capacity for 13 days it requires more water than the annual production capacity of the Ashdod water desalination plant. The water needs of a nuclear power station are between 20-80% greater than that of a coal, natural gas or fueloil operated power station
