Samples were collected from the outlet pipe greywater disposal of household and the combined channel in residential areas, and then analyzed in laboratory. The results showed that the parameters of pH, BOD, COD and TSS greywater of community settlements in the District Tamalanrea largely exceeded the threshold of environmental quality standards. While the greywater management system held separately from blackwater in a way to flow into the drainage channel without being processed first.
