Sioux City, Iowa, developed a GIS of its water, sanitary, and storm sewer
systems, and creation of a water model was the next logical step. Consultants
had previously developed localized models for site-specific projects. However, a
system-wide model had not been created for the metropolitan area.
The city developed the hydraulic model in-house using WaterGEMS. The GIS
was quickly converted into a working model, the customer service database
was incorporated to develop demand distribution, and GIS contours were
included to assign elevation to nodes. The model has been used to solve
problems with water pressure and fire flow availability as well as to assess
options for removal or rehabilitation.
Coffs Harbour City Council
2030 Smartboards—Telemetry System
Coffs Harbour, Australia
The water department of Coffs Harbour, Australia, developed an innovative
computerized control system that allows the water and wastewater system
throughout the Coffs Harbour area to be controlled remotely and alerts staff
immediately to possible pump or treatment plant failures. The $500,000 system
uses SCADA telemetry monitoring technology.
MicroStation and promis•e are the software behind the innovation. These tools
helped the water department generate electrical schematics, panel layouts,
bills of material, wire lists, and terminal plans. The collaborative features
supported multiple internal disciplines and third parties, such as the electrical
subcontractor. Coffs Harbour now works with other cities to help them utilize
this technology and learn from their experience.
