Optimatics helped Gold Coast Water become the kings of Queensland.

Gold Coast Water utilized Optimizer™ to carry out master planning optimization studies of the northern water supply districts (Gaven/Helensvale to Beenleigh) and central water supply districts (Molendinar, Southport and Nerang) of their system.

Optimizer was used to determine distribution system improvements for the systems subject to future demand conditions, as well as to consider intermediate years to provide information regarding the staging of proposed augmentations.

LOCATION:

Gold Coast Water, Queensland

 

MISSION:

Optimization of the northern and central distribution systems

 

USE CASES:

KEY POINTS:

  • Significant cost savings compared to existing plan
  • Optimize distribution and bulk transport systems
  • Optimization of pressure zone boundaries

“Most companies are quick to praise the capabilities of their products and services, but it is hard to know if they are really as good as they claim. I recently participated in the [Optimizer™ software] training and used Optimatics’ software myself; I can see that the Optimatics Genetic Algorithm is a very useful tool in optimizing the potable water supply network leading to a significant reduction in infrastructure cost.”

The optimization studies identified a number of current and likely future system operational issues particularly related to integration of a new trunk main (Southern Regional Water Pipeline), operation of the Molendinar treatment plant complex, and the shifting of zone boundaries.

The subsequent solution achieved significant cost savings as compared to the recommendations of the existing master plan (13% savings for the northern system and 31% savings for the central system). The cost savings were achieved despite the consideration of more than 100 fire fighting cases and a more stringent operational philosophy.

Planning new water sources for a city can involve a significant change in the flow paths of the bulk water. This can mean significant capital works and the need for optimal scenario modeling.

This optimization study enabled Gold Coast Water to save millions of dollars through improvements to their original design.
