The principle for the water abstraction charge is cost recovery, i.e. tariffs should reflect the total cost of providing water, including capital expenses, energy expenses, and expenses related to operation and maintenance. The means to include a component that reflects scarcity in the tariffs is to add the expenses related to the purchasing of desalinated w'ater on top of the other expenses. Water desalination is the costliest form of providing water in Israel and therefore reflects the marginal cost of producing water. Charges for pollution with domestic origin are based on the water consumption of the household.

In the following table, we report the pollution charge for non-domestic users for the Adour-Garonne river basin.
