The Forum of Water Corporations appealed to the government on Monday to replace the bottled water at cabinet meetings with tap water.
"Every week when I watch a broadcast from the cabinet meeting, I am amazed to discover that there are bottles of mineral water on the table," Forum head David Kochmeister, CEO of Jerusalem's Gihon water corporation wrote in a letter to the ministers.
"Bottled water is 100-250 times more expensive than tap water!" he added.
Furthermore, "drinking bottled water shows a lack of confidence in tap water, which the government itself is responsible for, and which is clean and fit to drink."
The Forum requested that the ministers abandon their half liter mineral water bottles by the next cabinet meeting.
