Chapter I General Provisions
Article 1.0.1 This standard is formulated to unify the design of ancillary buildings and ancillary equipment of urban water supply plants (hereinafter referred to as water supply plants) to achieve unified construction standards and control the construction scale.
Article 1.0.2 This standard applies to the design of ancillary buildings and ancillary equipment of newly built, expanded and rebuilt water supply plants.
Article 1.0.3 Water plants are divided into two categories: surface water plants and groundwater plants. The water supply scale is divided into five levels (0.5×104~2×10m/d, 2×104~5×10*m/d, 5×10*~10×10m/d, 10×10*~20×10*m/d, 20×104~50×10m/d). Water plants below 2×10m/d are small-sized water plants, 2×104~10×10m/d are medium-sized water plants, and water plants above 10×10m/d are large-sized water plants.
Data with a range of variation in this standard should be determined by interpolation. Article 1.0.4
Article 1.0.5 In addition to complying with the provisions of this standard, the design of ancillary buildings and ancillary equipment of water plants shall also comply with the provisions of relevant national laws and regulations and standards in force.

Article 2.5.1 The maintenance workshop generally includes a machine repair room, an electric repair room, a water meter repair room and a masonry room.
Section 2.5.Article 2 The machine repair room of a water supply plant is divided into two types: medium repair and minor repair. Medium repair mainly repairs components, while minor repair mainly repairs spare parts. The type of repair room should be selected based on the machine repair strength and cooperation conditions of the local water supply company. Independently set up pump stations can be determined according to minor repairs.
Article 2.5.3 The area and capacity of the machine repair room should be determined according to the scale of the water supply plant and the type of maintenance, and should comply with the provisions of Table 2.5.3. Machine repair shop area and staffing table
