Shanghai's Water Pollution: Can China Fix It?

Shanghai, China's financial and economic hub, epitomizes the global trend of urbanization. The city's rapid growth has placed incredible strain on its infrastructure and environment, with water pollution being a pressing issue. Despite efforts by the Chinese government and the World Bank to improve water quality, Shanghai's water crisis continues. This can be attributed to various factors, including a lack of enforcement of environmental regulations, insufficient water infrastructure, and the challenges posed by rapid industrialization and urbanization. With nearly a quarter of China's urban residents lacking access to proper drinking water, addressing water pollution in Shanghai is crucial for the health and well-being of its residents.

The Chinese government has been ineffective in enforcing environmental regulation

Shanghai's unprecedented surge in growth has placed incredible strain on its infrastructure and environment. The city's size, complexity, and accelerated demand for resources pose urgent challenges for the region. In the last three decades, the World Bank has been working with the Shanghai municipal government to promote sustainable urban development, with a focus on water management. Despite these efforts, the Chinese government has been ineffective in enforcing environmental regulation.

The environmental degradation that has accompanied China's rapid industrialization has been well-known since the mid-1990s, yet authorities have generally paid lip service to environmental regulation and have been unable or unwilling to enforce rules at the ground level. A "grow (and pollute) first, clean up later" philosophy was adopted, based partly on a desire to rapidly alleviate poverty, with the assumption that pollution could be dealt with later. This approach has led to severe water stress and shortages in water availability, with over half of China's water pollution coming from land use and degradation.

The Chinese government has struggled to crack down on polluting industries, with local governments often failing to regulate chemical waste disposal and track the transport of hazardous materials. In 2011, reports emerged that the Luliang Chemical Industry in Yunnan province had disposed of 5,000 tonnes of chemical waste next to a river used as a drinking water source. Despite the guilty verdict for several individuals involved, the local government took no action to regulate the company's chemical waste disposal.

Additionally, water purification technology in China is relatively outdated, with many companies still using conventional water treatment processes or having no treatment measures at all. The secondary pollution risk is heightened by aging water supply networks, and the byproducts of disinfection further affect water quality. The nationwide standards for sewage treatment are insufficient, and the health impact of water safety has become a significant public health issue.

To address these challenges, China should focus on enforcing stricter regulations on polluting industries, updating water purification technology, and improving the environmental health surveillance system. By investing in upstream land conservation and restoration, cities like Shanghai can reduce pollution and build healthier, more resilient communities.

Local governments have failed to crack down on polluting industries

Shanghai's rapid urban growth has placed a strain on its infrastructure and environment. The city's size, complexity, and accelerated demand for resources pose urgent challenges for the region. In the last three decades, the World Bank has been working with the Shanghai municipal government to promote sustainable urban development, with a focus on water management.

Despite these efforts, local governments in China have struggled to curb polluting industries effectively. For example, in 2019, China's environment ministry reprimanded provincial officials in Shandong, the country's biggest aluminum producer, for failing to comply with policies to reduce coal consumption and the growth of highly polluting aluminum output. Shandong was ordered to cap total aluminum production capacity at 4 million tonnes in 2017, but provincial choices and policy adaptations allowed the industry to exceed this limit. The cities of Binzhou and Liaocheng, home to China's two biggest private aluminum producers, were specifically accused of allowing and covering up illegal construction in the industry.

The Shandong environmental bureau announced a one-month pollution "rectification" campaign in response to the non-compliance. While this demonstrates a commitment to addressing the issue, it also highlights the ongoing challenge of enforcing environmental regulations at the local level.

In another example, the government of Mengzhou, which oversees the village of Sangpo, moved to close most of the factories in the village due to environmental concerns. This heavy-handed enforcement crippled the local economy, with hundreds of workers leaving town in search of employment elsewhere.

These cases illustrate the difficulties local governments in China face in balancing economic development and environmental protection. While there is a growing recognition of the need to tackle pollution, as evidenced by the central government's pledge to spend trillions of Renminbi on pollution control initiatives, effectively implementing and enforcing these measures at the local level remains a challenge.

The country's water purification technology is relatively outdated

China's water purification technology is relatively outdated. Many companies still use conventional water treatment processes, and some have no water treatment measures in place. This is despite the fact that China's Ministry of Environment has stepped up efforts to address water pollution. For example, in 2015, the ministry ordered provinces to meet their water quality targets, which are set every five years.

However, there is a lack of compliance from these provinces, and nearly half of the country missed its targets for the period 2011-2015. This non-compliance is also evident in the lack of regulation of chemical waste disposal by local governments, as well as the absence of monitoring systems for the transport of hazardous materials.

The outdated water purification technology, combined with insufficient regulation and monitoring, has contributed to the ongoing water pollution crisis in Shanghai. In 2015, 85% of the water in the city's major rivers was undrinkable, and 56.4% was unfit for any purpose. This crisis is emblematic of the larger issue of water scarcity and pollution in China, where over half of water pollution comes from land use and degradation.

To address this issue, China has implemented various initiatives. For instance, the World Bank has been working with the city of Shanghai for over 30 years to promote sustainable urban development, with a focus on water management. Through the Shanghai Adaptable Program Loan (APL), the World Bank has helped the city execute high-priority infrastructure investments in water supply, wastewater, and solid waste systems. Additionally, the Chinese government issued the Action Plan for Prevention and Control of Water Pollution in 2015 to strengthen pollution control and ensure drinking water safety.

Shanghai's rapid urban growth has placed a strain on its infrastructure

One of the most pressing issues is water management. Shanghai's water crisis includes deteriorated water quality, waterlogging, sewage overflow, and a lack of an efficient sewerage network. In 2015, 85% of the water in the city's major rivers was undrinkable, and 56.4% was unfit for any purpose. This is due to various factors, including industrial wastewater discharge, domestic sewage, agricultural hazardous pesticides and manure. Fertilizers, pesticides, and livestock waste are also carried into lakes, rivers, wetlands, and coastal waters, further polluting the water sources.

The Chinese government has recognized the severity of the water pollution issue and has taken steps to address it. In 2015, the Ministry of Environment ordered provinces to meet their water quality targets. Additionally, the government issued the Action Plan for Prevention and Control of Water Pollution to strengthen pollution control and ensure drinking water safety. Shanghai has also implemented its own initiatives, such as the Shanghai Sewage Project, which aims to improve water and wastewater infrastructure.

However, despite these efforts, challenges remain. Local governments have often failed to crack down on polluting industries, and there is a lack of monitoring and enforcement of environmental regulations. The clean-up process is made more difficult by the sheer scale of the pollution and the complex, interconnected nature of the country's water systems. Additionally, water purification technology in China is relatively outdated, and the aging water supply networks pose secondary pollution risks.

To address these issues, experts have suggested several solutions. These include making water pollution data publicly available to hold local governments accountable, setting ambitious water quality targets, and providing local governments with more resources for monitoring and enforcing pollution control measures. By implementing these strategies and continuing to invest in water infrastructure, Shanghai and China can work towards improving their water quality and ensuring access to safe drinking water for their rapidly growing populations.

The World Bank has been working with the city to promote sustainable development

Shanghai's rapid growth has placed incredible strain on the infrastructure and environment. The city's size, complexity, and accelerated demand for resources pose urgent challenges for the region. In the last three decades, the World Bank has been working with the city of Shanghai to help promote sustainable urban development, with a focus on water management.

The World Bank has been working with Shanghai since the early 1980s, when the city was facing serious water problems, including deteriorated water quality, water logging, sewage overflow, and a lack of a sewerage network. The municipal government turned to the World Bank for technically and economically sound solutions. In 1987, the $153 million Shanghai Sewage Project was launched to help build water and wastewater infrastructure in Shanghai. The project included the adoption of a combined sewerage system, long-distance transmission, and centralized treatment, and three sewerage collection catchments were constructed. The Shanghai Sewerage Company, one of the first self-financed sewerage companies in China, was established in 1992. This set up a market-oriented mechanism for corporatized operation in the sewerage sector and paved the way for collecting sewerage tariffs from residents and enterprises for the first time in China.

Through the Shanghai Adaptable Program Loan (APL), the World Bank has helped the city execute high-priority infrastructure investments in water supply, wastewater, and solid waste systems. Today, more than 2000 million cubic meters of wastewater are collected and treated for disposal, with a wastewater treatment connection rate of more than 90%. The World Bank also helped establish the first water authority in the country, which laid the groundwork for more efficient utilities operations and better water resource management strategies.

The World Bank has also supported low-carbon city development in Shanghai, with a focus on the Changning District. The Green Energy for Low-carbon City in Shanghai Project scaled up low-carbon investments in buildings, resulting in reduced carbon emissions and increased energy savings. The project involved retrofitting buildings with low-carbon technologies, such as improved lighting, heating, ventilation, and air conditioning systems. The World Bank loan leveraged co-financing from financial intermediaries, including the Shanghai Pudong Development Bank (SPDB) and the Bank of Shanghai (BOS), to finance investments in energy efficiency and low-carbon distributed energy resources.
