Today, the government approved the reduction of water rates by an amount equal to the VAT (17%), as part of the effort to reduce the cost of basic necessities in Israel.
The reduction will apply to the amount of water that is considered "basic" - the first 3.5 cubes per person. Amounts used above that will be subject to higher rates.
Make sure your water bill reflects the correct number of people in your household. If it lists fewer people than it should, make sure to fix that right away.
