Analysis of pollutant load due to greywater from riverbanks settlement on Ciliwung River segment 2

Abstract

Greywater from domestic activities on the riverbanks settlement in Indonesia usually channelled directly to the drainage or to the river. It will be decrease the river water quality. The aims of the research are to analyse the pollutant load that enters the drainage channel due to greywater from settlement in banks of Ciliwung River segment 2 and responses of society sanitation habits. The research was conducted at 6 villages are Babakan Pasar, Sukasari, Baranangsiang, Cibuluh, Kedung Badak, and Sempur. 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. Community awarness for sanitation habits such as environment community service and maintenance and handling waste in drainage.
