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 k...

This project is to conduct a hydraulic analysis for the proposed 600 mm diameter Zone 4 watermain on Heritage Road from Meadowvale Pumping Station (PS) to south of Steeles Avenue West. The proposed 600 mm diameter and 1300 mm long watermain will serve as a sub-transmission main and will be constructed of concrete pressure pipe (CPP). The proposed watermain will connect to the existing 750 mm diameter CPP watermain coming out of Meadowvale PS, existing 300 mm diameter polyvinyl chloride (PVC) watermain on Edgeware Road, and existing 400 mm diameter CPP watermain on Heritage Road south of Steeles Avenue West. The proposed watermain will serve to twin a section of the existing 400 mm diameter watermain on Heritage Road. The primary objective of the hydraulic analysis is to confirm and verify the proposed diameter for the 600 mm watermain, the location and size of all interconnections and connections, flow rates, operating pressures, and available fire flows. The hydraulic modelling is c...

This project is to conduct a hydraulic analysis for the proposed 750 mm, 300 mm, and 200 mm diameter Zone 5 watermains on Goreway Drive between Castlemore Road and Countryside Drive. The proposed 750 mm watermain will serve as a sub-transmission main and will be constructed of concrete pressure pipe (CPP) and will span approximately 3,000 m from Castlemore Road to Countryside Drive. The proposed 300 mm watermain is to replace the existing 300 mm ductile iron (DI) watermain on Goreway Drive with a length of approximately 710 m from Countryside Drive to Rosegarden Drive. The proposed 200 mm watermain is to replace the existing 200 mm DI watermain on Goreway Drive with a length of approximately 670 m from 133 m south of Rosegarden Drive to 124 m south of Latania Boulevard. The primary objective of the hydraulic analysis is to confirm and verify the proposed diameter for the 750 mm sub-transmission main, the location and size of all interconnections and connections, flow ra...

 The Regional Municipality of York (York Region, or Region) supplies water to nine area municipalities, including the City of Markham (Markham)’s and the City of Richmond Hill (RH)’s water systems. In turn, Markham and RH deliver water to individual consumers. Markham’s PD7 water system is supplied by the Region’s system via a single transmission main from Elgin Mills Road East and Highway 404, from hereon referred to as the Elgin Mills watermain. As there is no redundancy to the area, the supply should not be interrupted. Owing to a lack of redundancy and future anticipated growth around 19 th  Avenue and Highway 404, Markham has proposed a short-term solution to loop a 300 mm watermain with RH’s 300 mm watermain across Highway 404 close to Mobius Drive, from hereon referred to as the Mobius Drive watermain. This short-term solution would be in place until a long-term solution is developed, funded, and constructed by the Region. This study is to undertake a hydraulic analys...

This project is to conduct a hydraulic assessment of the proposed watermain network and booster pumping station (BPS) requirements for the proposed Ainslie Hill Residential Subdivision. Ainslie Hill Residential Subdivision, Town of Georgina is currently envisioned that the originally contemplated BPS to service these lands may be deferred to subsequent phase(s) of the development project. Given this shift in direction, as well as to address comments received on the original analysis, this report has been developed to provide the detailed hydraulic analyses with the following three considerations: Phase I Development without BPS Phase I & II Development with BPS Future Scenario of Phase I Development without BPS Figure 1: Location Plan.   Figure 2 : Combined InfoWater Model (red represents the system in Ainslie Hill Development).

This project is to design a sanitary pumping station (SPS) for the North East Albion area in the City of Maple Ridge, British Columbia. The SPS is located on 112 Avenue east of the bridge crossing with Kanaka Creek. This report presents and discusses the results of a numerical hydraulic transient analysis that has been completed based on the proposed design. The general objectives of the analysis are to review the pipe selection and to recommend the required surge protection equipment (if any) for the proposed 112 Ave SPS and forcemain.
