F.M. Woods WTP Upgrades

C3W was retained by the City of Guelph for the conceptual design for a two-phase upgrade being completed at the F.M. Woods WTP.

The first phase of the project involves converting the original pump station facility (ca.1879), which was designated as a City Heritage property in 1997, into office space for technical services and conservation staff.   The second phase of the project will see the construction of a replacement 1050 L/s pump station and wet well, replacement of the electrical power supply and distribution system, refurbishment of existing O&M facilities, construction of a new administration building and associated controls upgrades.

City of Cambridge- Water Audit & Water Loss Study

As part of its ongoing efforts to reduce water losses in the water distribution system, and reduce the levels of Non-Revenue water, the consultant team was hired by the City of Cambridge to perform an International Water Association (IWA) Water Audit and Water Balance for 2016. This audit quantifies water and revenue loss through physical leaks and apparent losses, helping the team to identify steps to minimize and improve system efficiency. The audit results serve as the baseline data to help the City to measure progress over time and aid in establishing a cost effective Infrastructure Leak Index (ILI) target.

City of Guelph- Transient Pressure Monitoring, Modelling & Mitigation

The City of Guelph water system operates with two pressure zones. A third zone is being developed and implemented. The elevated storage in the second pressure zone was taken out of service for rehabilitation and this pressure zone was converted to a closed pressure zone for the duration. Almost immediately, the City began to experience a number of significant water main breaks in a focused area of the pressure zone.

Region of Waterloo- Design and Construction Services for Region Well Supply Disinfection System Upgrades

The Terms of Reference for the Assessment of Groundwater Systems Potentially Under the Influence of Surface Water (GUDI-TOR) and the Ministry of the Environment and Climate Change (MOECC) Procedure for Disinfection are in the process of being updated to address the federal requirement for groundwater disinfection, which is now 4-log virus inactivation.  Detailed investigations into the level of disinfection achieved at Region of Waterloo (Region) supply wells, system wide, were carried out by C3 Water Inc. (C3W).

Impact of Proposed Provincial Well Supply Treatment Guidance Changes on the Region of Waterloo’s Water Supply System

The Region of Waterloo (Region), Water Services Division, hired C3 Water Inc. (C3W) to carry out a system wide review of the level of disinfection achieved at their system supply wells. The scope of work included identifying the impact of the proposed provincial well supply treatment guidance changes on the Region’s well water supplies, given existing system conditions and treatment infrastructure. Both the Terms of Reference for the Assessment of Groundwater Systems Potentially Under the Influence of Surface Water (GUDI-TOR) and the Procedure for Disinfection of Water Supplies in the Province of Ontario (PFD) are currently in the process of being updated. It is anticipated that these documents will echo the Canadian Federal Government’s move from a minimum treatment level of 2-log virus inactivation to 4-log virus inactivation for well supplies. Of this total required 4-log virus inactivation for primary disinfection, at least 2-log virus inactivation much be achieved through chlorine disinfection.

Region of Waterloo- St. Jacob’s Booster Pumping Station & Reservoir Inlet Piping Upgrades

In 2015 the Region of Waterloo (RMOW) required assistance for design and construction services for the implementation of an alternative reservoir fill piping arrangement at the St. Jacobs booster pumping station and reservoir facility. The facility boosts pressures for the supply of water to St. Jacobs and Elmira from the Waterloo pressure zone. The original reservoir fill line, installed in the 1990s, conveyed water to the reservoir through a globe style control valve. Due to the existing piping arrangement maintenance of the valve (and replacement) required a complete shutdown of flows into the reservoir.
