1.1 General Background of the Project
1.1.1 Origin of the Project
As the social and economic development of Yueshan Town, its urbanization development is further quickened and the township construction takes on a new look. However, there are still some problems required to be solved immediately, including the underdevelopment of township economy, the small size of economic aggregate, the lagging of township basis and public facilities, the sluggish flow rate of people and goods, the week effect of attraction, the rather serious environmental pollution, the shortage of construction funds and so on. The waste water from production and domestic uses, in particular, are discharged randomly without previous treatment and directly into surrounding channels through no discharge pipe, the results of which are rather serious pollution to waters and the surrounding areas and a huge impact on the life of the surrounding urban residents and further the gradual degrading of urban residential environment quality. Therefore, to further promote the healthy sustainable development of social economy of Yueshan Town, to improve township residential environment quality and to change the insufficient status of funds for basic facilities, Yueshan Town decides, according to the purpose of World Bank (“WB”) Loans “to improve the environment and to keep sustainable development”, to use the WB loans to quicken the construction of Hunan Integrated Economic Development Demonstration Town Project and to practically promote the fast development of social economy of Yueshan Town, on the base of reality and upon the site survey carried out by the development and reform departments of the province, the city and the town and by experts.
In December2010, Yueshan Town initially finished a discrimination report of Integrated Economic Development Demonstration Town Project Utilizing WB Loans. In January2011, to further quicken the development of the Project, the People’s Government of Yueshan Town consigned Hunan International Engineering Consulting Center to compile “The Feasibilities Study Report of Integrated Economic Development Demonstration Town Project Utilizing WB Loans”. In February2011, an expert team came and made a site survey and, according to the reality of the Yueshan Town, discussed with the People’s Government of Yueshan Town, studied and settled down a construction proposal and the content thereof which is to utilize the WB loans on launching contraction projects including the construction of a WWTP (WWTP) and the supporting engineering thereof, the industry development study of a small town, the administration study of a small town, the personnel training and so on. Currently, the preparatory work successfully proceeded.
Geographic location of Hunan Province in China is shown in Figure 1, of the Project in Figure2, and of the WWTP of the Project in Figure 3.
1.1.2 Significance of the Project Construction
The construction and implementation of the Project are full of below meanings:
(1) The construction of the Project can improve local environment, which is of benefit to the construction of a livable town.
The construction of the Project will improve the residential environment of Yueshan Town and complete the basic facilities. The construction of a WWTP and the supporting engineering thereof will effectively prevent pollutions; greatly improve people’s living conditions; protect surrounding water sources; beautify the surrounding environment; construct a more comfortable and beautiful living environment; improve and raise residential environment; quicken the construction of a livable town; and lay a better environmental foundation for quickening urban development.
(2) The construction of the Project is of benefit to improving the livelihood of the people and optimizing the soft environment necessary for development.
The implementation of the Project is aimed at optimizing regional soft environment necessary for development and putting forth effort to raise the livelihood of the people. On the base of the reality of Yueshan Town, via the construction of the WWTP and the supporting engineering thereof, Yueshan Town will exert its effort to increase the taste of the town, to optimize the soft environment, to accelerate the continuous strengthening of town functions and to improve the quality of people’s life so as to further generate a powerful cohesion and strong driving force, effect and attraction to accelerate related industry cluster; to boost investment invitation and capital introduction; to promote regional industrialization, urbanization and agricultural industrialization; to quicken the steps of pushing regional economic development and building a better-off society in an all-around way; to drive economy and all social undertakings to develop in an all-around, healthy and harmonious way; and to strive for the construction of a modern livable town of a new type.
1.1.3 Target of the Project
General Target:
The construction of the Project aims at raising the level of urban basic facilities of Yuehsan Town, strengthening public service function, improving investment environment, boosting swift economic growth of Yueshan Town and ensuring people living and working in peace and contentment, so as to lay a sound foundation for the all-around, harmonious, sustainable and steady development of social economic environment of Yueshan Town.
Detailed Target:
(1) To reinforce the pollution prevention and environmental protection of Xinqiaohe River, to implement a complex pollution prevention and reduction measure through controlling the pollution from the source, to control the pollution load on the river and to increase the number of people participating wastewater treatment so as to improve environmental monitoring, monitoring frequency and the quality; and
(2) To raise the level of urban basic facilities of Yuehsan Town and to enhance the living standard and the taste of the urban inhabitants, which are favorable to achieving investment invitation and capital introduction.
1.1.4 Contribution of the WB
The WB actively contributes to the improvement of city environmental basic facilities and the urbanization level. The Project is to utilize the loans and technical support of the WB of about USD 5,000,000 to build a WWTP in Yueshan Town, Xiangtan City, Hunan Province. It will increase a wastewater treatment capacity of 3,000m3/d, and reform and complete the urban wastewater collection network at the meantime. Via the implementation of the Project, the basic facilities and environmental conditions of the Project site can be effectively improved so as to make new contributions to the realization of the outline target of the “20th five-year plan”.
