1.0.1 This code is formulated to make the water supply engineering design conform to national principles, policies, laws and regulations, unify engineering construction standard, improve engineering design quality, meet customers’ demand for water volume, quality and pressure and to achieve safety and reliability, advanced technology, economy and rationality, convenient management.
1.0.2 This code is suitable for the permanent water supply engineering design of newly-built, expanded or reconstructed cities, towns and industrial areas.
1.0.3 The water supply engineering design shall be mainly based on the approved overall urban planning and specialized water supply planning. The choice of water source, determination of position of water treatment plant, water transmission and distribution pipeline shall accord with the demand of the relevant special planning.
1.0.4 The water supply engineering design shall consider the overall situation, including saving of water resource, water eco-environmental protection and sustainable utilization of water resource, correctly handle the relationship of various water uses and meet the requirement of building the water-saving towns and cities.
1.0.5 The water supply engineering design shall follow the principles of economical using of land and rational using of land resource. The quota of land for the use of construction shall conform to relevant regulations of Construction Standard of Urban Water Supply Engineering Project.
1.0.6 The water supply engineering shall be designed according to the principle of long-term planning, combining short with long term design and attaching importance on short-term design. The service life of short-term design shall be 5~10 years, and that of the long-term design shall be 10~20 years.
1.0.7 The rationally designed service life of the structure of water supply engineering shall be 50 years, and that of the pipeline and special equipment shall be determined according to material and product renewal cycle and through technical and economic comparison.
1.0.8 The water supply engineering design shall adopt effective new technology, process, material and equipment to improve quality of water supply, guarantee safety of water supply, optimize operational management, save energy and resources, and reduce engineering and operational cost on the basis of summarization of the experience of production practices and scientific experiment.
1.0.9 The water supply engineering design shall not only be conducted according to this code, but also shall conform to regulations of relevant current national standards.
The water supply engineering design in such areas as seismic, wet subside loess, frozen soil of many years and other special geological areas shall be done according to current related codes or regulations.
