Pipeline routing involves determining the path and location of pipelines on a plan; this includes main pipes, connection pipes, distribution pipes, and pipes leading to individual households. b. The layout of the pipeline network should comply with the urban planning plans: it is necessary to ensure a safe and reliable water supply ； Pipelines are spread throughout the water supply area to ensure that users have an adequate supply of water and sufficient water pressure ； c. The pipelines should be laid along the shortest distance possible. The direction in which the main pipes extend should be consistent with the flow direction from the secondary pumping station to the pools, water towers, and large consumers; one or several main pipes should be laid parallel to each other. The spacing between the main pipes can range from 500 to 800 meters, depending on the layout of the area. d. Connection pipes between the main pipes are used to form a circular network, and the spacing between these connection pipes can be around 800 to 1000 meters. Answers: b, c, d. Urban pipeline routing refers to determining the direction and location of pipelines on a topographic plan. During line planning, it is generally limited to the main pipes of the pipeline network and the pipes that connect these main pipes; it does not include the distribution pipes and service pipes that lead from the main pipes to the users. Therefore, option a is incorrect
