- Abstract:
- With the development of the city, water supply network in Puxi area of Shanghai is expanding and its layout becomes complicated. In order to explore the feasibility of the layout of water supply network with separating functions of water supply pipes and water distribution pipes in this area, a set of construction method for separation of water supply and distribution pipes was proposed combined with the characteristics of pipe network in Puxi area, which included definition of water supply and distribution pipes, selection of water source pipes, arrangement of monitoring points, etc. Then, a pilot project was carried out in BWT area of Puxi. By establishing a hydraulic model of the water supply network in this area and combining genetic algorithms, two water source pipes were selected to complete the separation of supply and distribution pipes. After a period of stable operation, a series of data was collected to evaluate the water pressure and flow pattern in the regional water supply network. It was proved that the separation of supply and distribution pipes was beneficial to regional pressure equalization and pressure reduction. At the same time, according to the analysis of the hydraulic model, it pointed out the areas that needed to pay attention to the water quality, namely the area with the longest water age and the pipe where the water flow pattern changed greatly.
