Appendix 1.6 Water standards Appendices 113 It is used to gather and sort the water standards from different countries and regions. Appendix.Table 10: General information of water standards no. Land / region water type 1 2 … … name of standard serial number issue year Explanation: this table records the general information of standards, and it is associated with the Appendix.Table 11 that stores the controlled parameters and values of the standards. Appendix.Table 11: Controlled parameters and values of water standards no. 1 2 … Name of standard parameter unit value (lvl. 1) value (lvl. 2) value (lvl. 3) value (lvl. 4) value (lvl. 5) Abbreviation: lvl. – level Explanation: each parameter can have several limited values in different levels. Maximum 5 levels are pre-configured, which are adequate for most situations.
114 New Conception and Decision Support Model for IUWS Appendix 2 Case study For demonstrating how to use the IUWS-DSM, a case study is performed. It is based on one Chinese city. The unavailable and inaccessible information that is essential for calculation is made up in order to execute the model. Therefore, the calculated values may deviate from the actuality. Appendix 2.1 Basic information Appendix 2.1.1 introduction to the city Taizhou is a fast-developing city located in the southern part of the Yangtze River Delta on the east coast of China. Taizhou City consists of three large independent urban areas i.e. Jiaojiang, Huangyan and Luqiao, which were two independent cities and one town in earlier time. Being transferred from a town, Luqiao has the large requirements of development and grows quickly now. Meantime, its water infrastructure is insufficient. Hence, Luqiao area is selected for this case study. Luqiao has a large administrative area with 274 km 2 , where mostly are farms and small villages. The total current population is 0,33 million. The land is flat in general. There are hills on the north-west and south-west sides of the area. The networks of natural waterways cover the whole area very well. So far the central urbanised area is around 9,5 km 2 with the population of 100 thousand. Luqiao has the typical subtropical monsoon climate with evident four seasons. The precipitation is abundant, with the average value of 1.530 mm/a. But it is uneven distributed, where 60% occurs in three rain seasons within a year. According to the statistical data, local water sources are insufficient at the level of 634 m 3 /capita. 85% of total water sources are the surface water. Most surface water is heavily polluted that cannot be as the source of drinking water. Abstraction of groundwater is strictly limited due to the risk of seawater intrusion. Therefore, Reservoir Changtan is the water source for the total Taizhou City. Reservoir Changtan is located 30 km in the west of the city. Currently, Luqiao has a waterworks with the maximum capacity of 40x10 3 m 3 /d. The source water is diverted from a pump station located in Huangyan. Luqiao has a wastewater treatment plant with the maximum capacity of 40x10 3 m 3 /d, which is located in the south-east corner of Luqiao next to the urbanised area. Appendix 2.1.2 study area There is a long-range city master planning for the whole Luqioa area (Appendix.Figure 6). Due to the master planning, the urban population will reach 0,32 million and daily average water demand will hit 287x10 3 m 3 /d over the whole planned area. A new transmission pipeline is planned, which directly diverts the raw water from Reservoir Changtan to Luqiao. In this case study, only the kernel area of Luqiao is chosen as the study area. First of all, neither detailed information nor detailed plans of suburbs and new area is available. Second of all, this case study focuses on demonstrating the way to use the model, so the narrowed
