Waste Water Management

The Sewerage Systems and Services Ordinance, 2005 was enacted in November 2005 for the State to develop and regulate wastewater management systems. This prioritises upgrading and maintaining the water quality of our rivers and streams in towns and cities.

The State Sewerage Services Department under the Ministry of Housing and Urban Development is responsible for managing water resources in a sustainable manner.

Wastewater (grey water and black water) from kitchens, bathrooms, wash areas and toilets will be collected via a sewer reticulation network and channelled to this treatment plant. The plant will process and treat the wastewater using the activated sludge system. The treated effluent from the plant will comply with Standard A of the Environmental Quality Act. The effluent will then be discharged into a constructed wetland before it finally flows into the Sarawak River.

Property Connections involve the collection and re-routing of existing wastewater into the public sewer networks. Wastewater from within property boundaries (residential, shops etc) will be collected and diverted via sewers within the property boundary to an Inspection Chamber, which will be situated next to the property boundary. From there, the wastewater will be connected to the nearest public sewer. A pumping system may be adopted for properties with limited space. In such cases, electric pumps will be installed in the existing septic tanks or package plants, which will be modified to suit. Upon completion of the property connection, the existing septic tanks or package plants will be disinfected and decommissioned.
