This standard is compiled by the China Urban Water Supply Association, the Urban Construction Department of the Ministry of Construction, in accordance with the spirit of the document No. 36 of the State Council [2000] "Notice on Strengthening Water Conservation and Water Pollution Prevention in Cities", and the requirements of the document No. 87 of the Ministry of Construction [2001]. During the compilation process, the compilation team collected the residential water consumption data of 108 urban water companies in the past three years and screened the valid data of 87 cities. It was compiled on the basis of extensive research and analysis of a large number of domestic and foreign statistical data, as well as investigation and analysis of the domestic residential water consumption status, and extensive solicitation of opinions from all parties. This standard is divided into three chapters, including general principles, terminology and water consumption standards. In order to effectively alleviate the shortage of water resources, the formulation of the "Standard for Water Consumption of Urban Residents" is a basic construction work in my country's water conservation work. It will play an important role in guiding the reform of urban water supply prices and establishing a reasonable water price mechanism with water conservation as the core.
This standard is managed by the Ministry of Construction, and the Urban Construction Department of the Ministry of Construction is responsible for the interpretation of specific technical contents. During the implementation process, it is hoped that local governments, administrative departments, water supply enterprises and other relevant departments will pay attention to accumulating information and summarizing experience, and please send opinions and relevant information to the Urban Construction Department of the Ministry of Construction (No. 9 Sanlihe Road, Beijing, Postal Code: 100835 Tel: 010-68393160) for reference in future revisions.

2 The assessment of urban residents’ domestic water use should not be based on days as the assessment cycle. The daily water consumption index should be used as the basic value for calculating the water consumption index in the monthly assessment cycle. 3 The upper limit value of the index value is determined based on the temperature change and the peak water consumption month change parameters. Residential water use can be assessed in sections within a year and adjusted using the interval value. The upper limit value can be used as the index value for the highest month in a year. 4 The calculation of the number of household water users shall be managed by local governments in accordance with local actual conditions.
