Doha North Sewage Treatment Works

Keppel Seghers is privileged to partner the Public Works Authority of Qatar to develop the Doha North Sewage Treatment Works. This landmark project is the largest greenfield wastewater treatment, water reuse and sludge treatment plant in Qatar.

With a peak design capacity to treat wastewater of up to 439,000m3 per day, the Doha North Sewage Treatment Works serves a projected population of over 900,000 people.

As a Design-Build-Operate project, Keppel Seghers designed and built the Doha North Sewage Treatment Works and has commenced the 10-year operations and maintenance of the plant since December 2015.

This modern facility features advanced biological treatment processes as well as membrane and ultra-violet technologies to produce high quality reclaimed water for reuse in agriculture. The facility will also be equipped with thermal drying processes to treat wastewater sludge. The dried and pelletised sludge will be used as soil conditioners or refuse-derived fuel.

Keppel Seghers Ulu Pandan NEWater Plant

Keppel Seghers Ulu Pandan NEWater Plant is one of Singapore’s largest NEWater plants and has the capacity to produce 148,000m3 of NEWater per day. It is also one of the largest wastewater recycling plants in the world.

NEWater is treated used water that has undergone stringent purification and treatment using advanced dual-membrane (microfiltration and reverse osmosis) and ultraviolet technologies.

The ultra-clean NEWater can be used in wafer fabrication, non-potable applications in manufacturing and air conditioning cooling towers in commercial buildings.

Awarded by PUB in early 2005 to design, build, own and operate the plant for 20 years under the Public Private Partnership initiative, the plant meets the demand from industrial and commercial sectors in the western and central regions of Singapore.

Marina East Desalination Plant

Marina East Desalination Plant Water Purchase Agreement signing ceremony

On 20 January 2017, Keppel Infrastructure, through its wholly-owned subsidiary Marina East Water Pte. Ltd., signed a 25-year Water Purchase Agreement with PUB, Singapore’s national water agency, for the Marina East Desalination Plant, the nation’s fourth desalination plant.

Located in Marina East, the plant is being constructed under a Design, Build, Own and Operate model and is expected to be operational in 2020. Keppel Seghers has undertaken the turnkey construction and commissioning of the project, while Keppel Infrastructure Services will operate the plant.

When completed, the plant will be able to produce up to 137,000m3 of fresh drinking water daily. Keppel Infrastructure will supply product water to PUB over a 25-year concession period from 2020 to 2045.

The plant will be the first in Singapore with the ability to treat both sea water as well as fresh water from the Marina Reservoir by using reverse osmosis and other advanced membrane technology.
