IDModeling Professional Services Saves City of Westminster, CO Nearly $1 Million

IDModeling Professional Services Saves City of Westminster, CO Nearly $1 million

The City of Westminster (City) selected a team supported by IDModeling (IDM) Professional Services for the preliminary design of a storage tank, additional pumping, and a transmission main. The project required detailed hydraulic model evaluations using the City’s water distribution system model to verify the need, size, and location of the proposed improvements.

The Benefits: Applying the operational model resulted in nearly a $1 million capital savings by verifying and validating that pipeline improvements would not be required. Additionally, the operational model identified an open zone valve, that once addressed, had an immediate positive impact on over-pumping and energy costs. “In addition to the estimated capital savings, addressing the zone valve issue allowed us to reduce pumping, and increased our confidence in the model as an operational tool”, said Tom Settle, Water Treatment Superintendent for the City, “We are excited about how this model can be applied to other areas of our system to improve our operational efficiencies”.

The Approach: To evaluate conveyance and general system operations, the steady-state planning model was extended to a 48-hour Extended Period Simulation (EPS) model, specifically suited for operational analysis. The model was used to simulate existing pump and tank operations to verify improvements required for the proposed storage tank.

“This project’s outcomes are a great example of the benefits of hydraulic model applications: from verifying and prioritizing planned CIP, to simultaneously improving day-to-day operational efficiencies and effectiveness” said Jason Pierce, IDModeling Project Manager, “It was a pleasure to work on this project, and with this team, to apply our passions to such tangible benefits for the City.”

City engineering and operations personnel were actively involved in the project, from providing input on existing operations, to verifying that the operational hydraulic model was adequately simulating recorded and observed facility operations.

The Challenge: The City’s 2011 Water Infrastructure Master Plan recommended additional potable water storage to meet build-out water demands, and the Northridge Water Tank No. 3 was the first storage tank identified in the CIP. As part of the proposed storage tank project, the City was prepared to construct new waterlines to enable the existing and planned storage facilities to operate effectively. Other recent transmission main improvements had changed the behavior of existing facilities, and as a result, new pipelines were anticipated to restore adequate operations. The City’s water model contained steady-state scenarios suitable for planning purposes, and the City recognized the value in developing an operational hydraulic model to verify the need for additional capital facilities.
