Using multi-disciplinary 3D software, Design Team can visualize and “walk through”
City of Leduc Reservoir and Pump Station during design process

Leduc Pumphouse 3D Rendering - Intake Piping and Distribution Pumps.

The City of Leduc, located 33 kilometres south of Edmonton, Alberta, retained Associated Engineering to provide engineering servicesto complete the preliminary design for a new reservoir and pump station in the southeast section of the city. These facilities include a 4,500 cubic metre water storage reservoir and a new pumping facility to provide additional storage and distribution capacity to meet peak hour demands, along with the required fire flow.

The Leduc Southeast Reservoir and Pump Station (Southeast Reservoir) operate in parallel with the Leduc South Reservoir as they both fill during non-peak hours and supplement peak hour water requirements by pumping reservoir water back into the same system from which it was supplied. Both reservoirs are supplied by the Leduc North Reservoir, which in turn is filled from the Capital Region Southwest Water ServicesCommission (CRSWSC), which provides treated water from EPCOR Water Services Ltd. The Southeast Reservoir is configured with two holding tanks which feed into a pump reservoir. The pump reservoir uses three controllable pumps to move the reservoir water back into the city water system.

Throughout the system flow, pressure and free chlorine are monitored with control then applied to valves and pump operations.

A stand-by pump is present for high demand, fire duty, and backup water in the event of a power failure. This pump is coupled to a generator which provides backup electrical power for the control system, emergency lights, and heating.

The control system is networked to the central control facility in Leduc via a SCADA link using a radio link.

Benefits of 3D Design
Since 2005, Associated Engineering has completed several projects using AutoPLANT software in conjunction with AutoCAD 3D. The software provides a multi-disciplinary 3D platform for structural, process, building mechanical, and electrical disciplines. Although the projects have been completed either partially or entirely in 3D, not all of the AutoPLANT modules had been utilized. Additionally, no multi-disciplinary 3D team had been assigned to the projects that have been completed in 3D.

Project Manager Patrick Mastromatteo comments, “Although 3D was not a requirement of the client, Associated Engineering determined that this particular design was an ideal application for which to formulate a multi-disciplinary 3D design team.”

Three independent software packages were used to complete the 3D model, Bentley AutoPLANT, Autodesk Revit Structure, and Autodesk3D’s Max. One of the many benefits of using 3D modeling is visualization. Patrick advised, “By enabling you to see the project in an actual solid looking format, you can do a “virtual walk-through” and detect unforeseen design, fit, and function flaws early in the design process. Also, it is much easier for clients to understand and provide feedback on 3D models than technical drawings. Design partners and clients can understand complicated concepts faster and easier when they can see conceptual models.”

Associated Engineering staff who worked on this project include Project Manager Patrick Mastromatteo, Colin Madden, Stuart Miller, Adam Rees, Roger Nelson, Mitch Lejeune, Duskanka Stevanovic, Max Kante, and Scott Kusalik.
