【10】Green infrastructure in Singapore

Singapore launched a bold campaign in the early 2000's to become the world's foremost knowledge and practicing city center for green infrastructure, smart city water management technologies and wastewater reuse.

Singapore's Utilities Board markets a bottled "New Water" product that comes from triple membrane filtrated sewage treatment plants.

The crowning glory of Singapore's water savvy is the engineered surface of its city, much of it designed or retrofitted in green infrastructure.

Two thirds of the city – rooftops, parks, medians, sidewalks, roadways – capture rainwater and convey it or pump it via microprocessor-controlled channels or tunnels to 18 reservoirs.

Singapore not only demonstrates for the world the design and engineering potential of urban water reclamation through green infrastructure, but it shows how doing so can create an international center of excellence that can result in substantial economic returns in water-sensitized forms of urban planning, architecture, engineering, information technology and green infrastructure innovation
