Keppel Marina East Desalination Plant

  • Location: Singapore
  • Client: PUB, Singapore’s National Water Agency
  • Project status: Complete

Project Overview 

The Keppel Marina East Desalination Plant is the first dual-mode plant in Singapore. It provides 137,000 m3/d of clean water by treating two sources of water: seawater from the Singapore Straits and stormwater from the Marina reservoir. It is the only treatment plant located at the city fringes and near water demand zones in the city and eastern Singapore.

Our role

  • Engineer to PUB, Singapore’s National Water Agency, for the island republic’s first dual-mode desalination plant
  • Consultant for the plant to be built under a design–build–own–operate model in four stages:
    1. Tender preparation, including preliminary design and tender documentation
    2. Tender evaluation
    3. Financial close
    4. Construction


  • Interfacing with a diverse range of stakeholders throughout the consultation process
  • Forming an integrated approach to maximise the investment benefits
  • Enhancing the environment through sustainable urbanisation made possible by engineering and design excellence

Unique features and solutions

  • City fringes, close to water demand areas in the city and eastern Singapore
  • 20,000 m2 of green roof provides a recreational area for leisure and relaxation
  • Seamless integration with nature and surroundings through a tree canopy
  • Jogging and cycling tracks integrated with the Eastern Coastal Park Connector Network
  • Viewing gallery with glass panels so the general public can observe desalination equipment by appointment
  • Cascading water feature provides security and smart rainwater management
  • The underground treatment facility does not compromise the aesthetics of Singapore being a “garden city”
  • Close to the Marina Coastal Expressway

Benefits and Achievements


“We were tasked to look into the possibilities for conceptualising a dual-mode water treatment facility that would be located close to the city and would not compromise the aesthetics of Singapore being a “garden city.”
