Quantity and quality of household wastewater in Kuching, Sarawak

In Kuching City, individual septic tank is the most common form of sewerage system for most of the residential areas whereby effluents are discharged into municipal storm drains. However, little is known about the contribution of household wastewater towards river water quality degradation. In thi...
