Every effort is made to provide sophisticated infrastructure that offers modern conveniences and reliable access to utilities provisions. A comprehensive underground Common Services Tunnel houses telecommunication and utilities networks in a “plug-and-play” format, with 100% emergency backup services and the capacity for expansion to meet changing utility needs. A district cooling system also ensures uninterrupted 24/7 operations. Marina Bay is also well-equipped for digital lifestyle with an established Wi-fi infrastructure.
Another key infrastructural project is the Marina Barrage which is a dam built across the Marina Channel to form Singapore 's 15th reservoir and first reservoir in the city. The Marina Barrage creates a freshwater reservoir to boost Singapore 's water supply, acts as a tidal barrier to prevent flooding in the low-lying city areas, and offers a spectacular venue for water-based recreation in the heart of the city.
