Developing the Dual Engines Focus

2. Integrated SGR Infrastructure System

With regard to infrastructure system, apart from district cooling system, we
will also increase the proportion of greening/renewable energy usage as far
1
as possible. In addition, we will incorporate the concept of “Sponge City”
and construct advanced food waste/sewage sludge anaerobic co-digestion
facilities, common utility tunnels, reclaimed water treatment facilities, etc.,
in the Northern Metropolis and the KYCAI, so as to minimise the demand for
resources. We will also reserve land for building waste recycling facilities
and various facilities for supporting the development of a smart city.

“Sponge City” means that a city can function like a sponge that has great resilience. The stormwater could be
absorbed, stored and cleaned during rainy days, and could be released and utilised as needed to enhance the
ecological function and reduce flooding in the city.
