Hong Kong is one of the world’s most populous cities and its daily per capita waste generation is higher compared to its Asian counterparts. In December 2017, Keppel Seghers and Zhen Hua Engineering (Zhen Hua) were awarded a HKD 31 billion (about S$5.3 billion) contract by the Hong Kong government to design, build and operate an Integrated Waste Management Facility (IWMF) off the coast of Shek Kwu Chau.

As Hong Kong's first IWMF for municipal solid waste, the Facility will reduce the total volume of waste directed toward Hong Kong’s landfills thus extending the lifespan of landfills, while generating about 480 million kilowatt-hours of green energy.

The IWMF comprises a waste-to-energy (WTE) Plant, a mechanical treatment plant for sorting and recycling of glass, plastics and metals, a desalination and wastewater treatment plant, as well as ancillary facilities. The onsite desalination plant will supply process water for the IWMF, and the wastewater treatment plant will ensure that all effluents are treated and reused as process water in either the WTE or mechanical treatment plant, or for general washing and landscape irrigation within the IWMF. With extensive greening, the IWMF is designed to integrate seamlessly with its natural surroundings.

Our proprietary WTE technology will be implemented in the IWMF, ensuring that the plant’s emissions comply with international standards. After the IMWF is completed in 2024, we will operate and maintain the facility for a period of 15 years. Through our proven technologies and solutions, we contribute towards shaping a more sustainable future.  

Water consumption is increasing at twice the rate of population growth globally. Singapore’s water demand is expected to almost double in the year 2060 from about 430 million gallons a day in 2018. In a bid to become self-sufficient, Singapore has adopted NEWater and seawater desalination as key pillars of the national water strategy.

Keppel Infrastructure was appointed by Singapore’s national water agency PUB to design, build, own and operate the country’s fourth desalination plant. First of its kind, the Keppel Marina East Desalination Plant (KMEDP) is a large-scale dual-mode desalination plant that can treat both seawater and freshwater by using reverse osmosis and other advanced membrane technology.

Located near the downtown Marina Bay area, the plant features a sleek modern design that breaks away from those of conventional water treatment plants and is the first to feature green spaces that can be used by the public for recreation. The plant’s water treatment equipment is located underground, and is topped off with 20,000 square metres of open green rooftop space for community recreation. It also incorporates environmentally friendly features such as rainwater harvesting.

The plant is able to produce up to 137,000 cubic metres of fresh drinking water daily. Keppel Infrastructure will supply product water to PUB over a 25-year concession period from 2020 to 2045. By re-imagining how an infrastructure facility looks and operates, Keppel Infrastructure has demonstrated that engineering, functionality and design can be harmonised even for industrial projects.

Providing solutions for a cleaner future, Keppel Infrastructure has executed more than 250 water and wastewater projects in more than 25 countries worldwide. Keppel Infrastructure is also collaborating with Keppel Offshore & Marine to explore the development of floating desalination plants.
