This photo nicely demonstrates the position of two water mains underground exposed by construction, the deepest water main is barely 250 mm below grade. Because it is shallow, close to the surface, that means 1) it can be easily damaged, and 2) cold water is not kept cold, due to warm soil temperatures in summer.
The most sustainable option for our buildings would be to make use of existing building stock, we find (thanks to the Hong Kong audit department) a gift – Hong Kong has schools which have been vacated, some vacated for many years, that have not been returned to Government, idle they serve no purpose, but they are an invaluable resource. the work has been done they have been built, they have infrastructure (water/drainage/power) and often very good links to public transport.
These vacant idle buildings can immediately be opened and put to good use, I can imagine several solutions, that could meet societies needs today:
These would be short term plans, no long leases, this does not need to be lifetime commitment, these existing buildings can be used today! and contribute to society and sustainability, over the short term, because Government will need time to figure out how to deal the land over the long term. Of course, Government being government they will immediately say No, I can imagine the countless excuses, but they might, just might, say Yes.

Hong Kong may have a new electric bus, sooner than you think. The new vehicle was spotted around town last week, outside HKPC in Kowloon Tong, and at the Eco Asia Expo 2015 exhibition.

Considering Hong Kong’s small area, this E-Bus must be killer app for Hong Kong’s urban pollution problems. I understand that many argue against EV’s because the rational is that EV’s merely move the pollution problem from our lungs to the distant electricity generating stations, and they claim that is a problem?
Repeated studies have shown the pollution at street level is often intolerable with excess PM2.5 PM10 and NOX. (nitrogen oxides). However, these power generating stations already have pollution control measures in place, and are discharged far from the lungs of busy pedestrians presently dodging the fumes in Central.
Burning diesel at street level should be a crime nowadays! Now we know, the diesel combustion (petroleum diesel not bio diesel) process the combustion is incomplete, and creates tiny microscopic soot particles, they are so small they are easily inhaled, hence the grave concern over particulates in the PM2.5-10 range. Hong Kong’s EPD in fact publish the monitoring data:

And the source of those PM2.5 and PM10 particulates? the overwhelming majority are created by diesel engine discharged at lung (street) level. Furthermore, I understand that the E-Bus creators (designed in Hong Kong!) have useful applications in mind for the ‘used’ batteries, to avoid creating another waste problem dealing with spent batteries. I had a tour, inside it looks like every other Hong Kong bus, in fact you would find it hard to distinguish between the diesel version, except for the tailpipe.
Another sustainability perspective to consider, beside being conceived and designed in Hong Kong, it is manufactured close to home, avoiding the related emissions caused from importing buses from Europe which I understand is the usual practice.
Let us hope it is on the road, here in Hong Kong, sooner rather than later. One of Hong Kong’s key selling points must be the fantastic low cost, public transport system, but can it be improved? Of course, there is always room for improvement, as Paul Zimmerman points out, there are water taxi’s and ferries that would improve connectivity across the harbour, however the Hong Kong public transport system is one that many cities envy.
