What is wastewater tax splitting?

Up until now, the wastewater charges were calculated from the consumed amount of fresh water. The amount of fresh water cannot be used as basis to determine the amount of the wastewater according to current law. Therefore, the calculation of the amount of water entering the channel is composed of wastewater and precipitation water. The proportion of wastewater is still identical to the amount of the consumed fresh water. The proportion of the precipitation water is calculated according to the sealed area of a property.
