1 General
1.0.1 This code is formulated to make the water supply engineering design conform to national
principles, policies, Jaws and regulations, unify engineering construction standard, improve
engineering design qua lity, meet customers' demand for waler vo lu1ne, qua lity 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 c ities, 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 consLruction 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 attach ing importance on sho1t-term design.
The service life of short-tenn design shall be 5- 10 years, and that of the long-term design shall be
l 0-20 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 equip1nent shall be determined according to 1naterial
and product renewal cycle and through technical and economic comparison.
1.0.8 The water supply engineering design shall adopt effective new technology, process,
1naterial and equipment to improve quality of water supply. guarantee safety of water supply,
opti1nize operational management, save energy and resources, and reduce engineering and
operational cost on the basis of sumn1arization 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 seis1nic, wet subside loess, frozen soil
of 1nany years and other special geological areas shall be done according to current related codes
or regulations.
