Project:City of Guelph– Water Servicing Master Plan, Servicing Studies and Modelling Support

C3 Water has provided hydraulic modelling and infrastructure planning services to the City of Guelph since 2014. 

Water Servicing Master Plan- C3 Water was awarded the contract for updating the 2009 Water and Wastewater Servicing Master Plan to ensure the water and wastewater infrastructure continues to support Guelph’s population growth from now until 2051. The 2020 Master Plan Update is intended to identify existing capacity constraints within the water and wastewater systems, as well as provide long-term servicing strategies. This is being done by evaluating various servicing alternatives and determining the preferred alternatives to support planned growth across the City.  This includes a major update and calibration of the water model to include all pipes, valves and hydrants. 

This Master Plan follows the Municipal Class Environmental Assessment (Class EA) process, and includes the completion of Phases 1 and 2.

The Master Plan will:

  • Consider the impact of population and employment growth beyond 2041/2051,

  • Further the City’s focus to become a Smart City, and

  • Consider the use of innovative technologies for improved water and wastewater level of service.

Infrastructure Servicing Studies- C3 Water was retained in 2015-2018 to review the upgrades associated with Pressure Zones 1 and 2.  The City had identified several projects through the 2009 Master Plan including storage, feedermain and pumping capacity to alleviate existing concerns and growth impacts. The purpose was to provide a feasible implementation plan to minimize risk to City, optimize the operation of the overall water system and provide the best value. The evaluation of inground versus elevated storage was undertaken. The City’s all pipe model was utilized to help identify the most economical combination of upgrades. C3 Water carried out evaluation of alternatives based on social, environmental, financial and technical feasibly criteria to assess criticality and prioritize proposed solutions. The final report recommended infrastructure alternatives and timing based on hydraulic modelling and evaluation scores. The Zone 1 study, completed in 2018, outlined a plan to delay $37M of infrastructure upgrades while meeting current and future needs of Guelph to 2031.

Operational and Emergency Modelling Services- C3 Water currently has an ongoing contract with the City to provide modelling services for operational support and to provide 24-hour modelling assistance should an emergency arise.

Project: Region of Waterloo- System-Wide Disinfection Review and Disinfection Upgrades Design & Construction Management

C3 Water was retained by the Region of Waterloo to complete a study of the impact of proposed treatment guidance changes, minimum disinfection level of 4-log, on the groundwater supply system. Scope of work included collection and review of existing background information, analysis of the existing raw water quality, development of treatment strategies and proposed upgrades. The intent of the study was to identify gaps between the existing treatment systems and the anticipated treatment guidelines.

While predominantly focused on disinfection performance, several wells utilized UV for primary disinfection only, on systems where the raw water hardness and TDS were causing an unusually high level of UV reactor cleaning and servicing. C3 Water analyzed alternative treatment strategies, reviewed O&M time studies, and completed an analysis of water balance using the RTW model and developed a proposed solution.

Recommendations to upgrade groundwater (category 1) wells G5/G5A, H3/H3A, H4A, G9 to provide additional chlorine contact time and remove UV irradiation were adopted by senior management. Recommendations to upgrade chlorine contact time at GUDIWEF (category 2) wells W10, K23, and G4/G4A and then challenge the source water characterization under the new proposed guidance document for identifying microbial treatment for sub-surface water supplies were adopted by senior management.

Detailed design was completed and two contracts were tendered for the upgrades. Contract 1 incorporated the groundwater wells and contract 2 incorporated the GUDIWEF wells. C3W worked directly with the Region’s Engineering and Planning and Operations and Maintenance groups to successfully deliver this project.  All project milestones have been achieved, including the construction of well to waste discharge line erosion control systems. C3W delivered the project within budget, and construction costs were within acceptable tender ready cost estimate tolerances.  The warranty period for both contracts has been completed and certificates of final completion have been issued to the contractors.
