2020 Hydraulic Transient Analysis for Stewart Road Booster Pumping Station | Town of Collingwood, ON, Canada

This project is to conduct a hydraulic transient (surge) analysis for the proposed Stewart Road Booster Pumping Station (BPS) located on Stewart Road at Sixth Street, Collingwood, Ontario. The Town is undertaking the design and construction of upgrades for Stewart Road Reservoir and BPS, as well as a new 400 mm diameter watermain along Sixth Street from Georgian Meadows Drive to Tenth Line and along Tenth Line from Sixth Street to Mountain Road. The proposed BPS is required to allow further development in the central area of pressure zone 2 (Zone 2), and the proposed facility will initially service existing and Phase I water demands as per the Master Plan. The facility is also being designed such that it can be expanded in the future to service the Phase II water demands as per the Master Plan.

The primary objective of this analysis is to complete a formal transient (surge) analysis in support of the design of Stewart Road BPS and to consider its impact on Zone 2. To this end, the transient analysis presents the maximum and minimum total (operating plus transient) pressures for the proposed Stewart Road BPS and zone 2 water distribution system, and it provides guidance on the required surge protection for Stewart Road BPS. The results and recommendations from the transient analyses are presented and discussed herein.

2021 Hydraulic Study for Peel Feedermain Emergency Shutdown | Region of Peel, ON, Canada

Image
This project is to conduct a hydraulic analysis for the emergency shutdown of that portion of Peel Feedermain along Rutherford Road between Huntington Road and Pine Valley Drive for purposes of making repairs at its valve chambers located at Highway 27 and near Napa Valley Avenue, all of which is located in the City of Vaughan (Vaughan). Without this portion of the feedermain in service, there is no connectivity between Airport Road Pumping Station (PS) in the Regional Municipality of Peel (Peel) and the South Maple Reservoir in Vaughan.  The remaining demands deriving water from the Peel Feedermain, including the industrial lands west of Huntington Road as well as the communities of Kleinburg and Nashville are insufficient to allow for proper operation of the duty pumps at Airport Road PS. The overall location of the proposed watermain replacement is presented a hydraulic model layout in Figure 1. The primary objective of the hydraulic analysis is to predict the performance of key i

2022 Water Quality Maintenance Plan | City of Markham, ON, Canada

Image
This project is to develop a Water Quality Maintenance Plan in the City of Markham for the purposes of ensuring that disinfectant residuals in the watermain system are maintained following its initial construction and commissioning.  This work is largely driven by the implementation of a large diameter (750Ø) trunk watermain along Warden Avenue extending northerly from Major Mackenzie Drive to Street E (see Figure 1 ), and for which there will be a relatively large volume of water with potentially little-to-no turnover until such time that sufficient demand is present in the system and/or connectivity to other parts of the City’s broader system is established. In this project, the residual disinfectant (total chlorine) concentration is determined as the minimum of the last week (7 days) of the 28-day simulation period. If the residual disinfectant concentration is at or below a threshold target (0.75 mg/L for the base case), an iterative process is followed to develop a flushing prog

2020 System Curve and Transient Analysis at Anne Street Pumping Station | City of Barrie, ON, Canada

Image
This project is to conduct a system (resistance) curve analysis and a hydraulic transient (surge) analysis for the proposed upgrades at Anne Street Booster Pumping Station (BPS) located at 164 Anne Street North, Barrie, Ontario. The Anne Street Reservoir and BPS was originally constructed in 1959 and is located within Zone 1 of the City’s water distribution system. The existing BPS pumps water into Zone 2 North (2N) by three vertical turbine pumps. The station also formerly housed Zone 3N pumps, which were removed during a 1984 modification. The 2013 Water Storage and Distribution Master Plan by AMEC (Master Plan) and subsequent 2019 Master Plan update by WSP have identified the need for a second Zone 3 North (3N) pumping station at the Anne Street Reservoir site to provide supply redundancy, fire flow demand, and system reinforcement. A complete rebuild of the existing Zone 2N pumping station was also recommended as it is reaching the end of its serviceable life. The first primary
