The Keppel Marina East Desalination Plant (KMEDP) was recognized by Global Water Intelligence as the Desalination Plant of the Year in 2021. Victaulic is proud to have provided grooved solutions, including couplings, fittings, and valves, to the piping systems on this critical infrastructure project.
Global Water Awards Desalination Plant of the Year
The Global Water Intelligence (GWI) is “the leading publisher and events organizer serving the international water industry.” Each year, the GWI recognizes initiatives, projects, plants, technologies, and companies that significantly contribute to the water industry with the annual Global Water Awards. To be selected as a Global Water Award winner, a panel of independent experts examines each nomination based upon a set of criteria that improved operations and energy efficiency, technological innovation, and the implementation of sustainable financial models.
The Keppel Marina East Desalination Plant (KMEDP), located in Singapore, was awarded the 2021 Global Water Award for the Desalination Plant of the Year. This plant demonstrates the “most impressive technical and ecologically sustainable achievement in the industry.”
Overview of The Keppel Marina East Desalination Plant
The KMEDP is the world’s first dual-mode desalination plant, built with the ability to treat both freshwater and seawater depending on weather conditions. This critical component of Singapore’s water security strategy was built to provide a reliable source of water to the city-state, capable of producing 127,000 cubic meters (approximately 30 million gallons) of drinking water each day.
Located in the Marina East area of Singapore, the KMEDP treats water from the Marina Reservoir and the Singapore Strait. The weather conditions in the area determine which water source will be utilized. During dry weather, water levels in the Marina Reservoir are typically lower, creating a need for seawater from the Singapore Strait to be pumped into the plant for desalination. When the Marina Reservoir water levels are higher due to periods of rain, the plant will treat water from the reservoir.
In addition to being a sustainable and efficient water resource, the KMEDP also provides urbanization benefits to Singapore. The plant and pumping station was constructed entirely underground. This created a 20,000 square meter (sqm) area of open green space on the rooftop of the plant dedicated to public recreation, which, integrates seamlessly with the surrounding greenery. KMEDP became the first industrial plant in Singapore to be awarded the Active, Beautiful, Clean (ABC) Water Certification (GOLD) by Singapore’s National Water Agency (PUB).

Victaulic’s Role in the Keppel Marina East Desalination Plant
Victaulic is proud to provide reliable solutions that support AECOM’s, the appointed engineer Keppel Infrastructure, design of this innovative large-scale desalination facility. The design included raw water intakes from the sea and reservoir to a dual flow chamber, through pre-treatment using flocculation and dissolved air flotation, then ultrafiltration; a two-pass reverse osmosis system; and post-treatment using ultraviolet disinfection.
Many of the above-mentioned systems at the KMEDP included Victaulic’s solutions for the desalination market. On the reverse osmosis system, the Series 465 MTS Plug Valve was utilized for on/off and cleaning in place (CIP) services. The Series 465 Duplex Plug Valve is designed to support high-pressure pumps, which feed the seawater to the membranes to remove salt, accommodating up to 80 Bar of working pressure. Additionally, the Series 465 Duplex Plug Valve provides a zero-leakage bidirectional valve solution, which met the design of the KMEDP.
With over 20 years of use in reverse osmosis applications, the stakeholders of the KMEDP knew that the Victaulic MTS Plug Valve solution they were utilizing would be of better quality and performance than any other option. Through the use of grooved couplings, fittings, and valves for super duplex stainless steel pipe, Victaulic provided a reliable and sustainable pipe joining solution that enabled a reduction in the construction schedule.
