To safeguard and enhance our residents' drinking water
quality, over the past year we have replaced old galvanised iron piping
with copper or uPVC lined pipes in a further
119 blocks (or a total of 618 blocks to date).
We have checked on the way we keep drinking water tanks clean. Laboratory
tests on water samples collected over 3 months at 3 housing blocks
showed the water was germ-free (E.coli and faecal coliform bacteria).

 |
| We have continued our work to cut down on water wastage
on our premises. |
 |
Each of our 6 new shopping centres were fitted
with self stopping taps. |
|
We installed isolation valves and check meters
in a further 9 estates (145 estates so far). |
|
We continue to check for water leaks in estates
and continue our re-plumbing programme. |
|
We have conducted research and will tell contractors
to try out fitting dual flush toilets into new estates. |
|
Over the past year, potable water use in our estates
from outlets under our control was 2.76% less than the previous year.
In the past year our contractors adopted water recycling systems for
bored piling works on 20% of our piling sites. We continue to work
with contractors to reduce water wastage in our building, piling and
civil engineering works and have been reviewing the effectiveness
of contractor's waste management plans to reduce both water wastage
and construction waste. Submission of these plans has been our requirement
since August 2000. |
