How to divide the property fee and water fee of small and high-rise buildings?

More than 5 floors (excluding 5 floors) need to use non-negative pressure equipment for water supply, and this part of the cost needs to be calculated and added on the basis of municipal water price; Below 5 floors, water is supplied by the municipal pipe network and charged according to the provisions of the Price Bureau.
