Urban domestic wastewater: how to reduce individual injection?

Abstract : 12 The present paper aims to identify ways to reduce pollution injected by residents in the urban 13 wastewaters network system. Two approaches are considered. The first one uses flow and 14 pollutant calculation to test whether a polluter can easily be identified in a neighborhood. The 15 second approach uses a survey to examine what incentive would be most effective to 16 influence residents' behavior. Hydrodynamic simulation results show that concentration 17 profiles at the network outlet corresponding to all possible polluters are similar and thus do 18 not point out specific resident source of pollution. Household level survey results show that 19 most socioeconomic and public good-related characteristics do not play a significant role in 20 explaining choices to discard in the home wastewaters network. Apart from the nature of the 21 waste itself, by far, the belief that the respondent has about her neighbors' and relatives' 22 discarding behavior is the main driver of the choice. 23 24
