Abstract: Abstract Water price is an economic approach to effectively promote urban residents to save water. However, due to the excessively large water volume and low water price of each tier in the tiered water pricing model, the water-saving effect of urban residents is not obvious. Determining the first-tier water price and water volume for urban residents has become an urgent issue to be solved both in theory and practice. Based on the basic water demand characteristics of urban residents, this study employs the ELES model and QUAIDS model to formulate an improved water demand-price function. The improved function model can describe the nonlinear relationship between urban residents’ water demand and water price. Then, based on the survey data of Zhengzhou City, combined with the improved function model and the Ramsey pricing method, a set of equations is built to calculate the basic water price and water volume that meet the basic living demand of urban residents. This method not only focuses on water conservation for urban residents but also considers their basic water needs and the water supply costs of enterprises, which provides a theoretical basis and practical guidance to promote resource conservation in China.
