Discrete drainage for Singapore's Skypark

Marina Bay is located near Central Area in the southern part of Singapore. Positioned along its waterfront is Marina Bay Sands Casino, whose presence is punctuated by three, 50 story hotel towers. The tri-structures are crowned by a 2 acre modern park containing a spectacular 150 metre long infinity edge swimming pool. Constructed by Venturer Private, the precinct is called the Sands Skypark, containing a bar, restaurant, spa, garden and observation deck. It can take a person twenty minutes to walk around its entire ellipse, offering 360° views of the city and the sea.

For such a large outdoor botanical precinct, designers required the surface water drainage to be functional and visually discrete. Peridean Landscape Asia Pte Ltd invited ACO Polycrete Pty Ltd, renowned suppliers of innovative drainage solutions, to provide input into the overall drainage design.

The drainage solution had do cater for a rainfall intensity of 330mm/hr and due to the physical constraints, could not protrude beyond a depth of 266mm. After some consultation and careful analysis by ACO's engineers, a solution was provided complete with run schedules and hydraulic profiles. This gave designers the confidence to specify ACO DRAIN's KS100 system as the project's surface drainage solution. In obscured areas, Heelguard™ stainless steel grates were used and stainless Brickslot, in highly visible areas. Brickslot, is a purpose made trench drain which allows designers to preserve the visual continuity of the pavement design whilst allowing drainage through a continuous slot.
