All septic tanks need to be desludged regularly in order to maintain treatment efficiency. The current practice in Sibu is to desludge the septic tank when it is full or blocked. There is also no proper septic sludge treatment facility. The sludge collected from septic tanks is currently being treated at the drying beds at Jalan Quarry, Sibu.

The proposed septic sludge treatment plant is located on an 8- acre site next to existing Kemuyang Sanitary Landfill. It is 25 km from Sibu Town center and 4 km from the nearest residential area.

The plant shall receive and treat septic sludge collected from the septic tanks within Sibu town and its outskirts. The treated sludge shall be disposed on site. This will enable the regular desludging of the septic tanks and package wastewater treatment units in Sibu. This will improve the efficiency of the wastewater treatment facilities in Sibu.

This treatment plant is designed to have an ultimate capacity of 300 m³/day.
