1 General Provisions
1.0.1 This code is developed with a view to unifying the design standards for pumping station, guaranteeing design quality of pumping station, as well as realizing advanced technology, safety reliability, and economic rationality of pumping station engineering.
1.0.2 This code is applicable to the construction, extension and renovation designs of large- and medium-size water supply and drainage pumping station.
1.0.3 Basic data shall be extensively collected and arranged for the design of pumping station. Basic data shall be analyzed, accurate, reliable and in accordance with the design requirements.
1.0.4 Pumping stations shall be designed on the basis of practical experiences, necessary scientific experiments, energy saving, as well as active and careful selection of new technologies, new materials, new equipments and new processes.
1.0.5 In the area where dynamic earthquake peak acceleration is greater than or equal to 0.10g, seismic design shall be carried out for major buildings. In the area where dynamic earthquake peak acceleration is 0.05g, seismic calculation may not be carried out but proper seismic measures shall be adopted for Grade 1 buildings.
1.0.6 Not only the requirements stipulated in this code, but also those in the current relevant ones of the nation shall be complied with for the design of pumping station.
