Shanghai's Water Pollution: Can China Clean Up?

Shanghai, China's financial and economic hub, has been facing severe water pollution due to the country's rapid industrialization and urbanization. In 2015, it was reported that 85% of the water in the city's major rivers was undrinkable, and the problem has persisted despite efforts by the government and organizations like the World Bank to improve water management and infrastructure. The challenges in addressing water pollution in Shanghai are compounded by the complex interplay of socioeconomic factors, rapid urban growth, and the strain placed on the city's infrastructure and environment. While there have been initiatives and investments to tackle water pollution, the effectiveness of these measures remains uncertain, and Shanghai continues to grapple with the issue of polluted water.

The Shanghai Sewage Project was launched in 1987 to build water and wastewater infrastructure

In 1987, the $153 million Shanghai Sewage Project was launched to address Shanghai's critical water issues by constructing water and wastewater infrastructure. The project included the construction of a combined sewerage system, long-distance transmission, and centralised treatment, with three sewerage collection catchments built. This initiative led to the establishment of the Shanghai Sewerage Company in 1992, marking the beginning of corporatized operations in the sewerage sector. The company introduced a market-oriented mechanism, enabling the collection of sewerage tariffs from residents and businesses for the first time in China.

The Shanghai Sewage Project was a collaborative effort between the municipal government and the World Bank, marking the start of a long-term partnership focused on sustainable urban development and water management. Shanghai, as one of the world's largest metropolitan areas, epitomises the challenges of rapid urbanisation. The city's population surged from 13 million in 1990 to 24 million by 2016, placing immense strain on its infrastructure and environment.

Prior to the project, Shanghai faced significant water-related issues, including deteriorated water quality, water logging, sewage overflow, and the absence of a sewerage network. The World Bank provided technical and economic solutions, assisting the city in executing high-priority infrastructure investments. Today, Shanghai successfully treats more than 2,000 million cubic meters of wastewater, achieving an impressive wastewater treatment connection rate of over 90%.

Through the Shanghai Adaptable Program Loan (APL), the World Bank supported the establishment of the city's first water authority, enhancing utility operations, water resource management, and tariff increases. The Laogang Landfill in China, a "build, operate, and transfer" (BOT) project, is another notable achievement under the APL. Additionally, the World Bank has been instrumental in promoting sustainable urban development, with a focus on water management, to address the challenges posed by Shanghai's rapid growth.

While the Shanghai Sewage Project has made significant strides in addressing water and wastewater infrastructure, China continues to grapple with severe pollution and environmental degradation resulting from rapid industrialisation. The country's "grow (and pollute) first; clean up later" approach has led to hazardous levels of air, water, and soil pollution, endangering the health and well-being of its citizens. However, there is growing recognition and commitment from the central government to tackle these issues, with plans to invest trillions of Renminbi in pollution control measures.

China's rapid industrialization has caused environmental degradation, with severe water pollution

China's rapid industrialization has resulted in severe environmental degradation, with water pollution being a pressing issue. This problem is particularly evident in Shanghai, one of the largest metropolitan areas in the world and the financial and economic hub of China. The city's unprecedented growth has strained its infrastructure and environment, with its size, complexity, and accelerated demand for resources posing urgent challenges. Shanghai's water crisis is emblematic of the broader challenges faced by China as a result of industrialization.

The roots of China's water pollution crisis can be traced back to the country's rapid industrialization and the accompanying lack of effective environmental regulations. For decades, China pursued a "grow (and pollute) first; clean up later" approach, prioritizing economic growth over environmental concerns. This has resulted in severe water pollution, with industrial wastewater, domestic sewage, agricultural pesticides, and manure contaminating surface and groundwater sources. In addition, local governments have often failed to enforce regulations or crack down on polluting industries, further exacerbating the problem.

The impact of water pollution in Shanghai is significant. According to reports, 85% of the water in the city's major rivers was undrinkable in 2015, and 56.4% was unfit for any purpose. This has serious implications for the health and well-being of the city's residents, as access to safe drinking water is a fundamental human need. The pollution levels in Shanghai's water are not an isolated incident but are reflective of a broader trend across China's major cities.

Despite the dire situation, there are signs of progress and efforts to address the water pollution crisis in Shanghai and China as a whole. The World Bank, for instance, has been working with the city of Shanghai for over 30 years to promote sustainable urban development, with a focus on water management. This collaboration has resulted in the implementation of high-priority infrastructure investments in water supply, wastewater treatment, and solid waste systems. Additionally, the Chinese government has recognized the urgency of the problem and taken steps to address it, such as issuing the Action Plan for the Prevention and Control of Water Pollution in 2015.

However, challenges remain, and the clean-up process is expected to be a significant undertaking. The current uncertainty lies in how much and how quickly pollution can be cleaned up. While air pollution is considered the most serious problem at present, surface water pollution is next on the list and should be amenable to clean-up efforts if effective measures are implemented. China's environmental ministry has also acknowledged the importance of addressing water pollution, setting ambitious targets for provinces to improve water quality.

Local governments have failed to regulate polluting industries, with a lack of enforcement of environmental rules

Shanghai's rapid 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. Local governments have often failed to regulate polluting industries, and there is a lack of enforcement of environmental rules.

In 2011, reports emerged that 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. Local residents reported that more than 140,000 tonnes of waste had accumulated over 22 years. While employees and contractors of Luliang Chemical Industry were found guilty of illegally discharging chromium-contaminated waste, the local government took no action to regulate the company’s chemical waste disposal. There was also no monitoring system in place to track the transport of hazardous materials.

This is not an isolated incident. In 1987, the $153 million Shanghai Sewage Project was launched to help build water and wastewater infrastructure in the city. Despite this, in 2015, 85% of the water in Shanghai's major rivers was undrinkable, and 56.4% was unfit for any purpose. The problem is partly due to a lack of enforcement of environmental rules and a failure to crack down on polluting industries.

The Chinese government has taken some steps to address water pollution, including the Action Plan for Prevention and Control of Water Pollution (2015) and the "Healthy China 2030" initiative. However, nearly half of the country missed its five-year water quality targets for the period 2011-2015, and in some provinces, the water quality even worsened.

To effectively tackle water pollution in Shanghai and other parts of China, local governments need to step up their efforts to regulate polluting industries and enforce environmental rules. This includes increasing inspections, improving technologies, and imposing legal penalties on companies that violate dumping laws.

China's water resources are estimated at 2,000 cubic meters per capita, a quarter of the global average

China's rapid economic growth and large population have made it one of the world's leading water consumers. China's water resources are estimated at 2,000 cubic meters per capita, a quarter of the global average, and this has been described as water poverty. The country withdraws approximately 600 billion cubic meters of water annually, surpassing the United States by 120 billion cubic meters. China's surface water resources include 2,598.44 cubic kilometers, and groundwater resources amounted to 792.44 cubic kilometers as of 2022.

The issue of water scarcity is exacerbated by pollution. China's water resources are polluted by industrial wastewater, domestic sewage, agricultural hazardous pesticides, and manure, which have contaminated both surface and groundwater. The effects of perfluorinated compounds (PFCs) and pharmaceutical and personal care products (PPCPs) on drinking water quality are also significant. In 2018, the Ministry of Water Resources evaluated 1,045 centralized drinking water sources and found that only 83.5% were suitable for a qualified centralized water supply.

The Chinese government has taken steps to address water pollution and scarcity. The Water Law, amended in 2002, includes sections on water allocation, extraction rights, use, conservation, and pollution prevention. In 2015, the Ministry of Environment ordered provinces to meet their water quality targets. The central government has also initiated programs to directly monitor water-polluting firms and sewage treatment plants. Additionally, the government has invested in infrastructure projects, such as the Laogang Landfill and the QCSRWP, to improve water management and supply high-quality raw water to Shanghai's districts.

Despite these efforts, China continues to face challenges in providing safe and clean drinking water to its growing population. The demand for drinking water is expected to increase as urbanization progresses, and water purification technology in China is relatively outdated. The country's rapid economic growth has also resulted in widespread water pollution, with nearly half of China missing its five-year water quality targets, according to Greenpeace research.

Shanghai, a city emblematic of China's improving quality of life, has also been affected by the country's water issues. The city has faced an "airpocalypse" emergency due to choking air pollution, and while the central government has pledged to spend trillions of Renminbi to tackle pollution, the clean-up efforts remain a work in progress.

Water purification technology in China is relatively outdated, with many companies lacking treatment measures

Shanghai epitomizes the global trend of urbanization, with a population of 24 million, making it one of the largest metropolitan areas in the world. This rapid urban growth has placed incredible strain on the city's infrastructure and environment, with water management posing urgent challenges.

While China has made significant progress in providing access to water supply and sanitation over the past two decades, issues of water scarcity and pollution persist. In particular, water purification technology in China is relatively outdated, with many companies lacking treatment measures. This has resulted in contaminated drinking water, with dissolved chemicals, and a lack of compliance with regulations.

The Chinese government has prioritized ensuring water supply over water quality, and while there have been efforts to promote health-related behaviors and improve water infrastructure, actual behavioral change has been slow, especially in poorer areas. The government has also struggled to enforce environmental regulations effectively, adopting a "grow (and pollute) first; clean up later" approach.

To address the issue of outdated water purification technology, China has implemented more stringent standards for water treatment plants, with the new standard (GB 5749-2006) controlling 106 water quality parameters. This standard, if effectively implemented and supported by a well-maintained pipe network, has the potential to ensure world-class water quality for communities.

Additionally, China has established the country's first water authority, leading to more efficient utility operations and improved water resource management strategies. The government has also invested in upstream land conservation and restoration, recognizing the impact of land degradation on water pollution. These initiatives demonstrate China's efforts to tackle water purification challenges and improve the quality of its water resources.
