Abstract
Models with a focus on the release of substances from domestic wastewater in China require data on the number of people served by a sewage treatment works (STW), but also the proportion of wastewater that is not treated by a STW, both of which are difficult to determine. It is also important to be able to reassess the coverage of wastewater networks periodically when evaluating long-term risk, as China’s wastewater network has expanding rapidly in recent decades. A methodology is described which can be used to determine the number of people releasing both treated and untreated wastewater within a Chinese river catchment using readily available data. This is applied to the East River catchment in South East China for 2010, 2015, and 2020. We determined that the wastewater network expanded significantly during this period, but there remain large areas of the catchment with no apparent wastewater treatment facilities.
