Jacobs to design greasy- and food-waste treatment at PUB’s Changi Water Reclamation Plant
- Jacobs was appointed by PUB to deliver engineering services for new greasy waste (GWTF) and food waste treatment facilities (FWTF) at the Changi Water Reclamation Plant.
- The GWTF is designed to treat up to 12,000 cubic metres of waste per month, equivalent to over 75,000 barrels of oil product.
- Jacobs will provide preliminary and detailed design for the GWTF, site supervision for construction, testing and commissioning, and a preliminary design study for the FWTF plus review of modification works.
- Co-digestion of greasy waste, food waste and used water sludge will increase biogas yield for electricity generation to power CWRP and reduce its carbon footprint; greasy-waste capacity is expected to double by 2025 with additions at Changi and Tuas.
Project scope
PUB appointed Jacobs to provide professional engineering services for new greasy waste (GWTF) and food waste treatment facilities (FWTF) co-located with the Changi Water Reclamation Plant (CWRP). Jacobs will deliver preliminary and detailed design and engineering for the GWTF, provide site supervision during construction, testing and commissioning, and carry out the preliminary design study for the FWTF. Jacobs will also review modification works to existing CWRP facilities to enable the planned co-digestion process.
Capacity and decarbonization
The GWTF is sized to treat up to 12,000 cubic metres of waste per month, noted as equivalent to over 75,000 barrels of oil product. Co-digesting greasy waste, food waste and used water sludge is expected to increase biogas yield; the additional biogas can be used for onsite electricity generation to power CWRP and reduce its carbon footprint.
Strategic context
Co-locating the new facilities with CWRP is intended to harness synergies from combined waste streams and boost Singapore's waste treatment capabilities. With the addition of facilities at Changi and Tuas, greasy-waste treatment capacity is expected to double by 2025, supporting PUB's aim to enhance water sustainability and contribute to a lower-carbon water-treatment process.
