What do you mean there are five waters at the same time and four waters at the same time?

Five waters, four waters and four decisions refer to the planning policy of canceling the contract. According to relevant data, in 2022, the Urban and Rural Water Affairs Bureau of Bincheng District put forward the idea of "four waters, four determinations, strong guidance and five waters development" around the ecological protection and high-quality development strategy of the Yellow River Basin, and called on the whole society to cancel the water contract.
