1Project Overview 1.2Water pollution situation

 The urbanization of Guiyang started late and entered the stage of rapid development from 2004. Only from 2004 to 2012, GDP growth exceeded 4 times. With the rapid development of the economy, more than 200 industrial enterprises and daily sewage along Nanming River discharged a large amount of sewage into the river every day. The river gradually deteriorated, turned black, and became stinky. The water quality of the tributaries of Nanming River and Shixi River in the upstream city became poor class V, and the river course lost its natural purification ability.

 The black odor of Nanming River has seriously affected the production and life of residents along the river. It was imminent to control Nanming River and protect the mother river. The people were looking forward to it.

 1. Although Guiyang City has repeatedly treated Nanming River, it has not been able to get a fundamental improvement in the

water environment. The pollution situation of Nanming River has seriously affected the normal life of the local residents and the

city positioning of Guizhou's pioneering demonstration zone for ecological civilization and “cool Guiyang”. The new municipal

party committee and municipal government faced great challenges and required a systematic solution to the problem of water

pollution in Nanming River Basin in a short period of time.

 2. Due to historical reasons, the economic development of Guiyang started late. There is a certain contradiction between

economic development and environmental protection. The task of river basin governance is tough, and local government faces

great financial pressure.

 1.After full investigation of water control mode across the country, Municipal Government of Guiyang changed its idea from investment and construction to purchase of services and process supervision. In order to break the traditional governance model of “segmentation and multi-head water control”, a permanent institution - Nanming River Rehabilitation Project Headquarters, was established, with the head of the municipal administration as the commander, and the head of the relevant municipal functional department as the deputy commander. Municipal ecological, urban management, water affairs and other functional departments and and county leaders as members, and regularly held meetings to promote planning, bidding, state-owned assets supervision, price verification, project auditing, financial accounting, legal negotiation, fee payment, etc., to simplify the procedures, which greatly improved work efficiency and quality of government services, providing a well organized working system to the implementation of the project.

 2.The Municipal Government of Guiyang has made up its mind to open up the market. They adopted the PPP model in advance, and introduced social capital with strong technical, financial strength and social responsibility through public bidding. The government assigned professionals do professional work, which is to take responsibility of the whole process of project planning and design, investment and financing, construction and operation management.

3.2Nanming River PPP model effect 3 Experience

 (1) Adjusting municipal planning, distributed construction, and greatly saving investment.

 Guiyang is a karst landform, urban water use is difficult to dispatch, and land resources are scarce. Guiyang City originally planned to adopt the “large cut-off” planning scheme. A large-scale sewage treatment plant was built in the lower reaches of Nanming River. No plant was built in the upper and middle reaches of the city. The designed sewage collection pipe has a large diameter and a long distance, involving a large number of demolition and land acquisition, and the project investment is large. China Water Environment Group re-optimized the original municipal planning with the principle of “modelrate concentration, local treatment, and near reuse”, saving pipe network construction and land acquisition investment of about 1.5 billion yuan, and operating electricity charges for water and water supply is about 30 million yuan.

“Intensive concentration, on-site treatment, and near reuse” innovative drainage planning concept, saving investment of pipe network is about 1 billion yuan, and saving annual operating cost is 0.3 billion yuan;

The annual saving of water resources is nearly 100 million tons, and the annual water saving cost is 158 million yuan;

The construction period saved 30% ~ 50%, which has played an important role in the success mode of Guiyang City and the successful passing of energy conservation and emission reduction assessment.

 (4) Increase the amount of water use in river landscapes Through the implementation of this project, the sewage treatment rate of Nanming River Basin has increased to over 95%, and the water quality and sensory effect of the branch and main stream will be further improved. The water body of poor class V water quality decreased from 51% to 7%, the class V water body increased to 26.8%, the class IV water body increased to 31.6%, the class III water body increased to 35.6%, and the river water supply along the river sewage treatment plant is about 330,000 tons/day. The service area has expanded about 90 square kilometers. The main indicators (BOD5≤10; COD≤40; NH3-N≤1.5) of the 65% inspection section of the main stream and the five tributaries meet satisfies the water consumption of the ornamental landscape environment.

 (5) Revitalizing stocks and optimizing debts

 Through the introduction of social capital, the project will expand the financing channels, transfer the franchise rights of some sewage treatment plants and new sewage treatment plants that were originally built, and bundle them with Nanming River water environment comprehensive improvement project, and the transfer price of the franchise is specially invested in the river basin management. The investment gap is subsidized by the government to purchase environmental services, which greatly alleviates the pressure of short-term payment of funds during the government construction period, effectively revitalizes the stock and optimizes the debt.

 (6) Qualitative evaluation

 During the implementation of the project, with the promulgation of documents such as the Ministry of Finance's Caijing [2014] No. 113 document, the Guiyang Municipal Government introduced a third-party professional consulting agency to conduct a qualitative evaluation of the project. Judging conclusions: From the perspective of project service price, service quality, investment efficiency, risk allocation and implementation efficiency, Nanming River Comprehensive Renovation Phase II Project is more suitable for operation in the PPP model than the traditional government investment method.

3 Experience 3.3Implementation points

 (1) Find suitable project investors

 PPP is not a short-term relationship love, but a long-term marriage. The partner of the project is "a family." Therefore, the selection of project investors must meet the

government's investment needs: comprehensive technical capabilities, a high degree

of social responsibility, quality and quantity to complete the task according to the

required time.

 (2) Evaluation of the feasibility of the program

 PPP projects must have a stable source of income, and their income should cover the investment of the entire project; Investors based on decades of operational objectives, fully consider the economical efficiency and validity of the project, and achieve their own reasonable interests within the scope of the government's ability to withstand. In the whole life cycle of the project, the investor has the subjective initiative to optimize and do the project well, and realize the value for money; The implementation of the PPP project should be matched with the development capability of the local regional economy. The PPP mode can alleviate the government's financial pressure, rather than bring more burdens to the finance.

 (3) Scientific system research, unified planning, and step-by-step implementation

The comprehensive rectification of the water environment is a system project with huge investment

demand and complicated operation, which has high requirements on professional technology and financial

security. Drawing on the successful experience of the Guiyang Nanming River Water Environment

Comprehensive Improvement Project, it is a prerequisite for the success of the PPP project to conduct

sufficient research and demonstration at the initial stage of the project. By overcoming the shortcomings of

“find-it and fix-it mentality” and the lack of systematic planning of the government in river basin management,

by re-optimizing the planning of river basin ecosystems and the layout of sewage plants, engineering

investment in pipe network collection, water transfer and water replenishment can be greatly saved. It also

greatly reduced the operating expenses of reclaimed water, which is the endogenous requirement and market

demand of projects invested by social capital.
