It originates from Pingba County, Anshun City, Guizhou Province. It belongs to the Yangtze River system and Wujiang River tributary. The drainage area is 6600km2 城区行政范围 and the total length is 118km, including 100km in Guiyang City and 36.4km in the city section. It accepts five tributaries of Madi River, Chenliang River, Xiaoche River, Shixi River and Guancheng River respectively. The leaders of previous provincial and municipal party 河 committees and governments attached great importance 鱼梁河 to the governance and protection of Nanming River. 明 南核心段 From 1985 to 1986, Hu Jintao, then secretary of the Guizhou Provincial Party Committee, personally took the lead in participating in the dredging of Nanming River and 小 achieved good governance results. 花溪河 黄 河 上游汇水区 南明河城区段水系图 Headquarter of Nanming River and Aha Reservoir Basin Water Environment Comprehensive Improvement Project 1Project Overview 1.1Nanming River Basin Overview • From 1985 to 1986, Hu Jintao, then secretary of the Guizhou Provincial Party Committee, personally took the lead in the dredging of Nanming River. • On August 24, 2016, Chen Miner, • On May 4, 2017, Chen Miner, then • On August 25, 2017, then secretary of the Guizhou Provincial secretary of the Guizhou Provincial Party secretary of the Guiyang Party Committee, inspected Committee, accompanied the Central 7th Municipal Party Committee, Li Nanming River project and Environmental Protection Inspector Group Zaiyong, current deputy governor inspected the Qingshan Wastewater to inspect Qingshan Wastewater Treatment of Guizhou Province, visited Treatment Plant.

Headquarter of Nanming River and Aha Reservoir Basin Water Environment Comprehensive Improvement Project 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. Headquarter of Nanming River and Aha Reservoir Basin Water Environment Comprehensive Improvement Project 1Project Overview 1.3The necessity of introducing PPP model into the project 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. Headquarter of Nanming River and Aha Reservoir Basin Water Environment Comprehensive Improvement Project 1Project Overview 1.4Project organization guarantee and implementation process 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 district 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. Headquarter of Nanming River and Aha Reservoir Basin Water Environment Comprehensive Improvement Project 1Project Overview 1.5 Implementation content The Nanming River Basin Water Environment Comprehensive Improvement Project is based on the principle of “Government-led, mechanism innovation, legal governance, science and technology support, participation by the whole people, and long-term governance for a long time”. The entire plan is implemented in phases. Phase I (November 2012~May 2013): Mainstream interception, dredging, dam renovation, 500,000 tons/day TOT stock sewage treatment plant upgrade, odor treatment, main flow ecological restoration, landscape enhancement, etc. The total investment is 1.1 billion yuan. Phase II (August 2014~December 2016): Focusing on improving water quality, tributary management, the construction of sewage treatment facilities (plants and pipe networks): Build new sewage treatment plants such as Xinzhuang Phase II and Huaxi Phase II (a total of 425,000 tons/day) and supporting pipe network, new sludge disposal center, control water quality from the source, and perfect the interception system for the tributaries of Shixi River and Guancheng River and improve ecological restoration of the interception system of Nanming River. According to the previous Nanming River treatment effect, the actual situation of the river ecological water quality and the recommendations of the experts of the three ministries, the municipal government approved the adjustment plan. Newly build Jinyang Phase II, Jinbai and other sewage treatment plants (140,000 tons/day), sludge resource disposal (500 tons/day), Nanming River ecological restoration, Huaxi River tributary treatment and river basin environmental Internet information supervision system construction and other projects to ensure that the ecological water environment in Nanming River Basin continues to get better step by step. Headquarter of Nanming River and Aha Reservoir Basin Water Environment Comprehensive Improvement Project 1Project Overview 1.5 Implementation content Phase III System Improvement Project (2016~2025): To achieve the goal of long-term clearance in Nanming River, adjust the coastal industrial structure, control agricultural non-point source pollution, gradually improve urban rainwater and sewage diversion, implement water and soil conservation and ecological restoration within the basin, and establish a long-term mechanism for pollution prevention and treatment. At present, in accordance with the requirements of the Guiyang Municipal Party Committee and the Municipal Government, in order to consolidate governance, the “One River” plan and the system improvement project is being implemented. By controlling the reduction of pollution sources, increasing the collection and treatment capacity of domestic sewage and initial rainwater, improving the tailwater discharge standards of wastewater treatment plants and the level of wastewater reclamation and utilization, strengthening the accumulation and utilization of rainwater in the later period to achieve water cycle balance and restore river ecology Headquarter of Nanming River and Aha Reservoir Basin Water Environment Comprehensive Improvement Project 1Project Overview 1.6 Content of completed major projects 1.External pollution control 11 sewage treatment plants have been built with a total scale of 940,000 m3/d; 3 under construction that gradually entered the trial operation, with a total scale of 75,000 m3/d; 5 upgradeds tock sewage treatment plant with a total scale of 3 500,000 m /d; the supporting sewage collection pipe 新庄污水厂 新庄污水厂 (二期) network has been improved 91.39 km.
