Copper Coast Water
Supply Master Plan
South Australian Water Corporation
The Copper Coast water supply system
serves a population of approximately 10,000
people on the Yorke Peninsula in the state of
South Australia. Summer tourism and increasing development in the region are increasing
the demand for water. This project was a
study of how to upgrade the water supply
system to meet the region’s requirements for
the next 25 years.
In addition to the hydraulic problems, any
future design developed had to ensure that
no additional chlorination was required. The
final design of the system incorporated a separate inlet/outlet at the tank site, with a pres-sure-sustaining tank inlet control valve. With this
design no further disinfection was required.
The total estimated cost for the system
upgrade is approximately $17,000,000
Australian. The upgrade involves significant
pipe duplication and replacement, a new 10
ML storage at North Yelta, and new control
valve installations. The first phase of construction will commence late in 2005. ;
Bentley WaterGEMS was used to hydraulically
model the existing system and assess appropriate solutions to future demand scenarios.
WaterGEMS’ integration with ESRI’s ArcGIS
8.x/9.x (the corporation’s GIS platform)
allowed some powerful spatial operations
during modeling. A current-demand scenario
was run to identify existing problem areas
and then a 25-year demand scenario.

GIS Intranet
Snam Rete Gas S.p.A.
The first advantage of the GIS Intranet system
is the immediate availability of the entire gas
distribution network to all remote Italian
sites. The new system of information distribution through the GIS Intranet system, based
on Geo Web Publisher, has dramatically
reduced the time needed to publish information and reports. With the new system, not
only are data immediately available, but also
the information guarantees precision, live
updates, and a richness
that could have not been
reached with the former
system. With several
queries, various data can
now be displayed on the
same image and be seen
both in alphanumeric
and graphic format,
allowing thematic representation. This is a great
help in maintenance and
operation, thanks to the
linked cadastral information that can identify owners
of the land the gas network
traverses. No one needs to
search on paper to locate data,
and remote sites need not ask
headquarters for paper
documentation. ;
