Assessing the social impacts of sustainable drainage systems (SuDS) provides relevant information for planners, developers and engineers to establish or improve systems that benefit the society and environment. This study aimed to assess the social impacts of SuDS in three flood-prone areas in Ozamiz City. Specifically, the paper obtained general information on SuDS. The knowledge of residents about SuDS was also assessed. The paper also examined if the existing drainage systems are safe, and affect the economic value and purchases of real properties. The fears of the residents associated with SuDS and the actions to improve or develop them were identified. A standard survey instrument was administered to 149 residents who were randomly selected. Results showed that water pollution and solid waste disposal are the major environmental concerns and urban areas were most polluted. Waste disposal via drains contributed most to water pollution. Sixty-four percent of the respondents were not aware of SuDS. Using SuDS could prevent flooding but the drainage stench is sickening. Economic value of surrounding real properties increases with SuDS and leading more individuals to purchase real properties in the vicinity. Risks for the children was the biggest fear with SuDS, followed by the risk of contamination and infection from the drainage canals. Creating walkways for the residents living near SuDS was highly recommended. The SuDS was regarded as the most beneficial environmental practice. The findings of this study may help the planners, developers, and engineers in improving or establishing SuDS in Ozamiz City.
