Why is the water fee in the kitchen the same as that in the bathroom?

Because the water in the kitchen and bathroom is the same. Toilets and kitchens in most communities use the same water, but they are all clean tap water. However, in some residential property projects in relatively developed first-tier cities, two water supply methods are adopted, namely, drinking tap water and using "reclaimed water" in toilets. Reclaimed water refers to the water treated by urban sewage treatment plants. Using reclaimed water not only saves water, but also saves money for owners.
