We green cities with solutions for waste and water & wastewater treatment.

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.  

Over the years, Singapore’s government has successfully developed new sources of water including NEWater and seawater desalination. NEWater is treated used water that has undergone stringent purification and treatment process using advanced dual-membrane (microfiltration and reverse osmosis) and ultraviolet technologies. A high-grade water reclaimed from treated effluents, NEWater is used mainly in industrial and commercial purposes. When required, NEWater can also be added to the Singapore’s reservoirs before being supplied to consumers as potable water.

Today, five NEWater plants supply up to 40% of Singapore’s current water needs, of which Keppel Seghers has designed, built and currently operates the second largest plant in Singapore – Keppel Seghers Ulu Pandan NEWater Plant. Capable of producing up to 148,000 cubic metres of NEWater per day, the plant was the largest water reuse plant in East Asia and the world’s second largest when it commenced operations in 2007. Keppel Seghers currently operates and maintains the plant under a 20-year contract with PUB, Singapore’s national water agency.

Keppel Seghers Ulu Pandan NEWater Plant features a 1 megawatt peak solar photovoltaic installation that helps to reduce the plant’s electricity consumption. Completed in 2013, the rooftop solar power plant is one of the largest in Singapore at 10,000 square metres. The installation was awarded the Solar Pioneer Award in October 2012 by the Energy Innovation Programme Office, led by the Singapore Economic Development Board and Energy Market Authority.

Providing solutions for a cleaner future, Keppel Infrastructure has executed more than 250 water and wastewater projects in over 25 countries worldwide.

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 will be located underground, and will be topped off with 20,000 square metres of open green space that can accommodate up to 700 people. It will also incorporate environmentally friendly features such as rainwater harvesting.

When completed, the plant will be 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.

District cooling systems (DCS) and district heating and cooling systems (DHCS) are centralised plants that can serve the air-conditioning as well as heating needs of a cluster of buildings at a time, via a network of distribution pipes. By aggregating energy loads across several buildings, these centralised facilities can greatly reduce overall capacity requirements and costs for heating and cooling precincts, achieving up to 40% in energy savings compared to standalone systems.

With a proven track record of over 20 years, Keppel DHCS has total contracted capacity of about 80,000 refrigeration tonnes (RT), and provides services to over 50 developments in Singapore and China.

Keppel DHCS is the first and largest DCS developer and service provider in Singapore, present in major business and industrial parks including Changi Business Park, one-north and Woodlands Wafer Fab Park.

DCS by the Park, which commenced commercial operations in 2015, is Keppel DHCS’ newest facility in Singapore. Designed to seamlessly blend in with the environment, DCS by the Park at Mediapolish@one-north features a green wall and a rooftop garden which functions as a communal space for public activities, with a semi-recessed plant integrated into the surrounding park. DCS by the Park is connected to Keppel DHCS’ plant at Biopolis@one-north, complementing the company’s service offerings to the entire one-north development.

In 2018, Keppel DHCS secured a contract for the initial design phase of a new DCS plant to be located in Bulim Phase 1 of Singapore’s upcoming Jurong Innovation District. Contingent on approval by JTC, there may be a subsequent phase of the contract to build, own and operate a DCS plant, with a capacity of up to 14,000 RT on a 30-year contract term.

Over in China, Keppel DHCS has been providing DHCS services to the Eco-Business Park of the Sino-Singapore Tianjin Eco-City since 2013, incorporating geothermal technology to support the Park’s heating and cooling requirements through renewable energy.
