1. Introduction
The aim of this report was to discuss how the climate change and urbanisation processes affected the design and management of wastewater systems in one of the countries of choice. In this report as an example China was used to describe the influence of urbanisation and climate change on design and management of wastewater systems.
Rapidly growing human population is expected to exceed nine billion people by 2050. Urban areas in developing countries are affected by rapid growth of population and poor infrastructure development. Already half of the human population live in cities where the infrastructure is not developed enough to sustain wastewater production. As the population increases so the production of waste water. In addition, climate changes affect the weather patterns, which directly influence a hydrological cycle. As a result one area suffers from rain fall shortage and others from more intense rainfalls.
2. China
In recent decades, China’s population has rapidly grown which caused rapid economic growth and increased the rate of urbanisation. At present china has one of the fastest urban population growth rate in the world.(UNDP 2013) All this happened along with proceeding environmental destruction and serious water pollution. The growing population of China has a high water demand as well as a lack of sufficient wastewater infrastructure. Those factors result in poor water quality and severe water shortages. In 2002 the rate of municipal wastewater treatment in China was 39.9 percent. (U.S Department of commerce 2005)

5. Conclusion
High rates of urbanisation and climate change in China has created many problems related to water resources. An increase in the population and a high urbanisation rate have effected and increased wastewater production. The Chinese water market is already under a huge amount of stress. The quality and quantity of water resources have been depleted due to the inefficient use of water. In terms of wastewater management China requires a long term strategy with sustainable solutions which will take into account climate change and the rate of urbanisation.
China economy has been falling for many years. Part of this downfall is lack of clean water. You know this, but know one in this world can’t live without water ,so that means water is very important. Climate change, Industrialization, and Government policy all contribute to the chinese water crisis. Of these, the biggest driver is the government policy. The government in China has a strict policy that does not allow the people to have water because China is not using enough money for their water.
It is true that there are factors contributing to China’s water scarcity, such as a bad government policy. However, the three biggest causes of China’s water-scarcity crisis are population growth, global warming, and especially industry. It is important because

In conclusion, this work has evaluated several solutions of the water shortage in China: water usage efficiency improvement, adopting the local agencies on controlling water resources and reasonable water pricing. It has been revealed that all of proposed solutions might be effective, but they should be properly applied and, probably, their combining can contribute to the combating the water scarcity in China. However, some of other solutions should have been evaluated, such as water recycling, and this work might become a base for further studies.
Due to industrial waste ,domestic wastes and agriculture wastes entering into water source, Chinese government reporting that nearly 60 percent of China’s groundwater is polluted. It also leads the decrease in water quality. A large amount of water cannot be used and thus foster the water scarcity problem in China.
China’s water supply is running out faster than it can be replaced. Water is being polluted by the environment, wasted because of the law, and a lot of water is being used due to it's growing industry. What is driving China’s water scarcity crisis? China's water scarcity crisis is mainly caused by the government mispricing water, industrialization, and urbanization.
In Document "C" the graph shows that over the span of 35 years China has used more and more water for Industries and Domestic uses, the industry has increased the most of the years and in 2030 it is projected to grow even more. Furthermore, in document "D" is a graph that shows the forecasted water usage in 2030, and it is estimated that 30% of the water in China will be used for power plants, 18% for smaller industries such as recycling, machine repair, heat supply and more, 15% for manufacturing, 10% of the water to textiles, and 27% of the water is split up and used for other industries like metals and mining, pulp and paper, food and beverages and more. This evidence tells me that China is focused on using more water for industries which is not good because when industry releases the left over water which is polluted and unusable and it is predicted that every year more water is going to be used for industries and not used to help stop the crisis. In conclusion, the last but not least reason for Chinas Water Scarcity Crisis is because of the misuse of
In 1950, only 13% of China’s population lived in cities (Seto, n.d.). Post 30 years, one hundred-million people moved to large cities from rural areas in China. This migration was considered the largest migration in human history. To compare this migration to western cities, the example of Shenzhen is used. For a Western city to have a population of three million to increase to ten million, it takes about a hundred years. 30-year old city, Shenzhen on the other hand made this population increase in just a decade (qtd. Caughey and Dawn). Today, over 53.7% of its population lives in cities; by 2020 it is projected that a whole 60% of the population will live in cities (Xinhuanet, 2014).
China has approximately 20% of the world’s population, which is around 1.3 billion people (Morris, 2009, p. 111). Also, China has become one of the worlds biggest manufacturing countries within 30 years (Fawssett, 2009, p. 27). However, such rapid development has come at a cost, which has created various environmental problems. Coincidentally, China has 16 cities on a list of the 20 worst polluted cities in the world (Fawssett, 2009, p. 15). Therefore, this essay will explain the reasons for China’s environmental problems, then evaluate the claim that the Chinese government and people, are tackling these environmental problems. First, crop farming techniques over the last hundred years, and their consequences will be explained. Followed by, how peoples choice in food has changed over the last hundred years, and how this indirectly affects the environment. Then, how a capitalist economy is linked to agriculture, and finally what the Chinese government and people are doing to tackle these problems.
Developing our national economy, especially industry, requires a great amount of natural resources, such as land, water, oil, coal, gas and iron. However, the natural resources are limited and decline very quickly when a large population exploits them everyday. Take fresh water as an example, in 1990, 58% of Chinese cities (http://www.cass.net.cn/y_sjr/y_cn_sjr_334.htm) suffered from the insufficiency of water. It not only brings great disadvantages to people's daily life, but also has a passive influence on the economic development. Released by the Chinese Academy of Social Sciences, the economic loss caused by the insufficiency of water is 250 billion RMB per year, including 230 billion lost industrial output and 20 billion agricultural losses.

Water treatment is considered to be a relevant action to ensure environmental sustainability. With an increase in water pollutants, water treatment plants are forced to develop additional processes in order to adequately purify the polluted water. In a report for the Chesapeake Bay Watershed it was stated that the presence of non-point source pollutants caused “a 35% increase” in cost for the wastewater treatment plant (Rees 2014). As well, a study in

Many of these in later years shall need to be addressed as tension rises: Saving and consumption of water Improving drinking water supply Increasing access to clean water supply Decreasing tension between war-ing nation over resources With the population expected to rise 40-50% within the next 50 years, the demand for water in Agricultural needs and Environmental needs will rise as well, creating a more desperate water crisis. Developed countries struggle with managing water consumption. Our high demand in agriculture, industry, and domestic use further complicates this issue. With increasing urbanization and extravagant changes in lifestyle, our use and wasting of water will only increase.
Water scarcity is harmful to human life because when water is poorly managed throughout the world, those who need water are deprived of nutrients they truly need, causing them to die. This eventually affects the global population. Therefore, many experts have proposed several solutions such as the LifeSaver Bottle, TrojanUVPhox treatment system, and Waste Water Recycling. The problem of water scarcity has increasingly spread throughout the world as of yet, The UN reports that within the next half- century up to 7 billion people in 60 countries which is more than the whole present population will face water scarcity (Sawin “Water Scarcity could Overwhelm the Next Generation”). As well, the demand for freshwater has tripled over the past 50 years, and is continuing to rise as a result of population growth and economic development.
