Keppel unveils designs for Marina East Desalination Plant
05 Jul 17 by desalination
Keppel has shared design details of its Marina East Desalination Plant project in Singapore, as it broke ground on 29 June 2017.
The primary function of the scheme is a desalination plant, and it will also serve as a public space. The 137,000 m3/d facility will be constructed over three hectares of land, and at 13 metres high will be mostly underground, with 20,000 square metres of parkland on the roof at ground level.
The dual flow chamber, which enables the plant to treat seawater and reservoir water, is also designed above ground as a playground area.
The engineering design shows raw water intake 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.
The architectural design enables the plant to blend in with the surrounding environment, with a private viewing gallery and the rooftop park at ground level.
“The Keppel Marina East Desalination Plant is the first to treat both freshwater from the Marina Reservoir, and seawater. This ability to switch from treating freshwater, to seawater during drier seasons, ensures a more weather-resilient water supply for Singapore,” said Keppel Corporation chairman Lee Boon Yang.
The project is expected to complete by 2020. Keppel Infrastructure, through wholly owned subsidiary Marina East Water, will construct the plant under a design, build, own and operate model, and has a 25-year water purchase agreement with PUB, Singapore’s water agency.
