Water samples were taken from the drainage channel in the morning and evening, which are considered to represent the peak hours of greywater. Sampling was conducted in May, June and July 2018. Pollutant load based on BOD level in the drainage channel ranges from 4,903.19-132,804.33 kg/day. This condition shows the high tendency of pollution due to greywater domestic activities and absence of greywater treatment in residential areas. Almost 50% of the community understand the importance of the need for wastewater management.
