摘要：While millions of people around the world die from natural water infections per day because of insufficient wastewater collection systems to cover all communities, 80 percent of used water is still released to the river in Thailand nowadays. As a result, the wastewater management (WWM) behavior of people is critical to water conservation. WWM, on the other hand, was fraught with high expenses and inconvenient installation, and earlier research had paid little attention to it. Thus, this research aims to study the socio-economic, cognition, opinions, and perception of information factors for analysis further of the factors affecting the WWM of people in urban areas, Thailand. This study applied multiple regression analysis from questionnaires survey of nine communities in Krathum Baen municipality, Samut Sakhon Province which is a semi-industrial area, crowded settlement, and risen wastewater unexpectedly along the Tha Chin River. The findings reveal that people in study areas have a moderate level of cognition and opinion toward WWM behavior. Perception of information was the best variable to describe the people's WWM behaviors in urban areas. Addressing the empirical results could contribute to water conservation planning, people engagement, and appropriately promoting WWM behaviors related to urban people.
