[music]>>SHOU: Welcome to Hong Kong. My name is
Stephan Shou, Client Director of Black & Veatch Water. Let me introduce some of the signature work
that we have been working for our client–Water Supplies Department, in Hong Kong. Active
leakage controls is one of the most strategic measures to control the non-resident water
within the territory. Pressure management and continuous monitoring schemes is one of
the most efficient and effective measures to control the non-resident water. Let me introduce some of the features in Hong
Kong. We have a lot of hills in Hong Kong, in such a way that some of the low-lying areas
are subject to excessive pressure. From a basic principle of physics, excessive pressure
will have pipe leaks and pipe bursts. Pressure management is one of the most effective ways
to reduce the pressure within the distribution system, and thus reduce the pipe leaks and
pipe bursts. Since 2005, we have been commissioned by the
Water Supplies Department to carry out studies and design of these pressure management schemes.
Out of 17 major supply zones within the territories, we have been working on at least 15 major
supply zones. Since 2008, we have also been commissioned
by Water Supplies Department to implement all these pressure management schemes within
Hong Kong, and within 2 1/2 years we have completed all the necessary schemes within
Kowloon Central, which is one of the busiest districts within Hong Kong. As a result, we are able to save 80 cubic
meters of water per hour and that’s equivalent to 2 million liters of water in a day, and
that’s also equivalent to almost 730 million liters of water in a year. In coming decades, we will be implementing
further management schemes within Hong Kong and this is the aim of the client to reduce
the leaks from 24 percent in the year 2000, down to 15 by 2015.
