The City of Stratford retained C3 Water to develop a calibrated water distribution network model using InfoWater. The City plans to use the model to evaluate future infrastructure as a part of Master Plan projects, for operational planning, water quality analysis, and development and redevelopment support.
The model includes all watermains and supply points from the City’s groundwater based water supply and distribution system, which is comprised of eleven wells and six treated entry points, one reservoir, two elevated tanks and one pressure zone.
High level components of the model development process for this project follow:
- Review of existing background information and identification of information gaps.
- Model build including integration of GIS watermain data, elevations, storage structures, sources, pumping stations and water demands.
- Steady state model calibration utilizing field testing results for fire flow and pressure.
- Extended period simulation model calibration using historical SCADA data.
- Development of a water distribution network model summary report documenting the model build process, assumptions made, system anomalies, summary of background data sources, calibration results and pressure mapping for a range of demand scenarios.
- Generation of detailed design drawings for demolition, process, electrical, I&C/ SCADA, and structural modifications. Generation of tender package including supplementary special provisions, form of tender, product specifications.
- Customized workshop with the City to provide training on model development, scenario management, analysis of the existing water system, analysis of future water systems taking into account redevelopment and new development, and model updates with infrastructure changes.
Now that the water model is completed, C3 Water provides ongoing model support for the City on an as-required basis. Previous support assignments include;
- Analysis of new developments and redevelopments.
- Operational support; i.e. analysis of system response to facility shutdowns, valve isolations, emergency events, and watermain isolations.
- Available fire flow and water quality analysis.
Watermain sizing exercises.
