Expansion -
more than meets the eye
When a resource
or product is in short supply, prices rise. That fundamental law of the
market applies even to the ground we stand on. The land in our urban areas
has been developed at a furious pace in recent years, creating a boom
in buildings that are almost as sky-high as the prices they command. But
an equally inexorable process is unfolding under the ground.
Construction is
going on under towns and inside mountains. Builders are putting not just
tunnels and trams underground, but also water purification plants and
power stations.
The advantages
are obvious: you don't have to expropriate land, wreck buildings or spoil
the environment. Unfortunately, the problems are often just as blatant:
Porous or undrillable rock, flooding that hampers construction, archaelogical
sites or delicate ecosystems that can be damaged by the perforation of
the land.
In this issue we
journey into a mountain and take a closer look at underground construction.
We also examine delicate ecosystems - albeit manmade - at the Villa d'Este
outside Rome and the new Congo Gorilla Forest at the Bronx Zoo. Water
plays a key role at both facilities, which fulfil a practical sewage treatment
function in addition to their aesthetic appeal. ITT Flygt's submersible
pumps are the very dynamos of these operations.
We talk to Kader
Asmal, South Africa's minister of education, who has been deeply involved
in both dam construction and water supply issues. His efforts have recently
earned him the Stockholm Water Prize.
For those of you
interested in matters of cost-effectiveness, I heartily recommend the
articles on our new N and slurry pumps. We have made a series of modifications
permitting the drastic reduction of a pump's total life cycle cost.
Enjoy!
