As part of the fifth largest water system in North America, the City of Toronto, Ontario supplies
water to 3.3 million consumers within the City and a large portion of the rapidly developing
Region of York to the north. In order to determine the long-term capability of the joint
Toronto/York water infrastructure to efficiently supply its consumers, the two municipalities
conducted a far-reaching and technologically advanced study.
Central features of the study were development and calibration of a hydraulic water distribution
model and optimization of infrastructure requirements using genetic algorithm (GA) technology.
Advanced modeling techniques included model development using state of the art software,
extended period simulation (EPS), the use of Automated Spatial Demand Allocation (ASDA) GIS
tools for water demand allocation and pump performance reviews using thermometric pump
testing.
The project included: selection of hydraulic modeling software; development of a water demand
forecasting and conservation model; forecasting demands to the year 2031; hydraulic model
development; continuous flow/pressure monitoring; supervisory control and data acquisition (SCADA) acquisition; model calibration and
optimization of infrastructure requirements using the GA techniques. The hydraulic model will be
an integral tool for the City and Region to conduct further applications in operations, energy
management and water quality modeling.
The optimization process summarized existing infrastructure expandability, alternative
infrastructure locations and water supply source options. GA model simulations identified
optimal system expansion strategies.
The result is a true picture of the joint capabilities of the Toronto and York systems and efficient long
term planning opportunities for both the City of Toronto (with its older established infrastructure)
and the Region of York (with its newer infrastructure and rapidly expanding consumer base) to
meet the combined needs of their consumers in a cost effective and efficient manner. Includes 4 references, figures.
