The new tariff will be a single slab and was printed on the February invoice to inform customers of the change said Mohammed Ali al Yahyaee PAEW's senior manager of operations and control.

Yahyaee said that the tariff will be 3.5bz per gallon for all three sectors up from the earlier 3bz. He said the average cost of production and distribution of water is nearly 7bz per gallon while it is sold at less than half of this amount.
