GB/T 44918-2024 in English

1. Introduction

With the acceleration of urbanization and the increasing shortage of water resources, the importance of water conservation management in urban water supply units has become increasingly prominent. This standard "GB/T 44918-2024" aims to standardize the water conservation management behavior of urban water supply units, improve water use efficiency, and ensure the sustainable use of water resources.

2. Background of standard formulation

This standard was proposed by the National Technical Committee for Water Conservation Standardization, combining advanced water conservation technologies and management experience at home and abroad. The drafting units include many well-known enterprises, scientific research institutions and government departments, ensuring the authority and practicality of the standard.

3. Interpretation of technical specifications

3.1 Water intake requirements

When surface water or groundwater is used as the water supply source, the water quality must meet the CJ 3020 standard. Regularly test water quality to ensure stable operation of the treatment process.

3.2 Water production requirements

Newly built, expanded and renovated water plants should be equipped with wastewater recycling facilities to reduce water waste during the water production process.

3.3 Requirements for water transmission and distribution

Reduce the leakage rate of the pipeline network through pressure regulation and pipeline maintenance. Refer to the CJJ 92 standard for leakage calculation.

4. Implementation suggestions

1. Strengthen organizational leadership and clarify the responsibilities of water-saving management departments and positions.
2. Increase investment in informatization and establish a management platform for full-process control.
3. Promote smart metering equipment, such as smart water meters and remote transmission systems.

5. Conclusion

Through scientific water-saving management measures and technical means, urban water supply units can effectively improve water use efficiency, reduce water waste, and lay the foundation for achieving sustainable development goals. It is recommended that relevant units actively implement the requirements of this standard and promote the construction of a water-saving society.
