As urbanization is accelerating and cities are becoming denser, the availability of clean water is increasingly becoming an issue. Moreover, the quantity of waste water produced from those vertical cities may place additional strain on existing infrastructures. This creates the opportunity for high-rise developments to move towards the industrial standard of “zero-liquid discharge,” with tall buildings themselves playing a role in ensuring water availability by reducing their water footprint. Achieving this requires solutions covering all aspects of water management, which includes the capture of water (siphonic roof drainage, balcony drainage, soil and waste water drainage, etc.), the collection and storage of water, and the treatment and reuse of water (irrigation, flushing systems, etc.). Increasingly, developers are integrating water management systems driven by public authorities, building certifications and clients' requirements for high-quality sustainable buildings, and long-term savings.

In this presentation, we shared our perspective on the megatrend of dense vertical cities, in combination with issues of water scarcity, potentially combined with heavy rainfall. The presentation also offered an overview of efficient and sustainable water management solutions, from the capture of water to its recycling and reuse.
