Hongya County Restructuring Component of Sichuan Small Towns Development Project by World Bank Loans / 1.0 Introduction1.0 Introduction
1.1 Project background and construction necessity
1.1.1 Project background
Hongya County has already determined in 2009 to implement the “Diverting Water from Qingyi River to the City” project by World Bank loans, and it has passed the World Bank Project Assessment in August 2010. The “Diverting Water from Qingyi River to the City” (diversion canal) project undertook by the county government has a total length of 9200 meters, and estimated investment of RMB 104,816,600. The project owner is Planning and Construction Bureau of Hongya County, and the construction unit is Zhejiang Provincial No.1 Water Conservancy & Electric Power Construction Group Holdings Co., Ltd., and Hunan Greenwood Urban Landscape Engineering Co., Ltd. The work has been carried forward smoothly through earlier stage land requisition and demolishing resettlement, currently, 9 Km. diversion canal construction of the “Diverting Water from Qingyi River to the City” project along with the harnessing of the moat at south and north of the city has been completed, promoting the reconstruction of the old city of Hongya County, improving the water system landscape along the canal, optimizing the land use pattern of the city, and improving the environmental quality.
Hongya County Restructuring Component of Sichuan Small Towns Development Project by World Bank Loans was officially put forward based on the above mentioned conditions, which is aimed to improve and extend the “Diverting Water from Qingyi River to the City” project of Hongchuan Town, and improve the life quality of the residents of and tourists to Hongya County through improving the municipal infrastructures of Liujiang ancient town. In June 2014, the Hongya County Housing and Urban-Rural Construction Bureau filled out the Project Screening Schedule in respect of the Hongya County Restructuring Component of Sichuan Small Towns Development Project by World Bank Loans. In August 2014, the Hongya County Housing and Urban-Rural Construction Bureau prepared the Project Proposal for Hongya County Restructuring Component of Sichuan Small Towns Development Project by World Bank Loans.
1.1.2 Construction necessity
I. Demands for improving the urban flood control standard to ensure the life and property safety of the residents
Hongchuan Town Subproject is closely related to the Hongchuan town environmental comprehensive control subproject of Sichuan Small Towns Development Project by World Bank loans. The important purpose of Hongchuan Town environmental comprehensive control subproject of Sichuan Small Towns Development Project by World Bank loans which is implementing by our county is to clear the sludge and bury the sewage interception trunk pipe by dredging the old riverways (channels) within the city, and introduce river water with Class 2 water quality (10m3/sec), and make the river water flows through the city from the west to the east by two riverways (channels) in north and south to comprehensively improve the urban ecological environment and purify the water environment.
II. Demands for improving the ecological environment to improve the life quality of the residents
Hongchuan Town Subproject is located downstream from the Hongchuan Town environmental comprehensive control subproject, and the existing ecological environment is very poor, and the Class 2 water quality of the introduced Qingyi River water can be maintained only after it is fully renovated and flows back to Qingyi River, thus the ecological balance idea of “return the borrowed water with good quality water” can be achieved, and ensure the integrity of Hongchuan Town environmental comprehensive control subproject of Sichuan Small Towns Development Project by World Bank loans. In conclusion, construction of the project is necessary and shall be carried out as soon as possible. The project is an improvement and extension for the important purpose of Hongchuan Town environmental comprehensive control subproject of Sichuan Small Towns Development Project by World Bank loans, and the adhering idea has a high degree of unity,.
