1.IntroductionThe aim of this report was to discuss how the humor change and urbanisation processes moved(p) the design and management of waste wet systems in one of the countries of choice. In this report as an example mainland China was used to describe the influence of urbanisation and mode change on design and management of waste water supply systems.Rapidly growing human commonwealth 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 provide one area suffers from rain fall shortage and others from more deep rainfalls.2.ChinaIn recent decades, Chinas populat ion has rapidly grown which caused rapid economic growth and increased the rate of urbanisation. At designate 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.

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.
