Denver Water

ORIGEN

Denver Water serves 1.5 million people in Denver, CO and its surrounding suburbs. The majority of Denver’s water comes from rivers and streams fed by mountain snowmelt. The South Platte River, Blue River, Williams Fork River and Fraser River watersheds are Denver Water’s primary water sources, but it also uses water from the South Boulder Creek, Ralston Creek and Bear Creek watersheds.

Denver Water serves about a quarter of the state’s population but uses less than two percent of all water, treated and untreated, in Colorado.

In 2012, Denver Water determined that the Foothill plant needed a complete overhaul of the electrical system to ensure the growing population would continue to have a quality water system. The project included the complete demolition and replacement of the facility’s substation and electrical service equipment. The Foothill plant is their largest and most critical treatment plant with hydroelectric generation.

UBICACIÓN

The city of Denver is at the base of the Rocky Mountains and is the largest city in Colorado. The city has a population over 600,000 and has grown almost 20% since 2010. The entire metro area’s population approaches 3 million residents.

ALCANCE

This project was both complex and on a rigid planned construction schedule. This plant has planned outages every five years and can only be down for a limited time so water storage is not compromised. Denver Water engineering department wanted only experienced and highly competent members on their team. Based on prior successful projects that PRIMEX has completed for Denver Water, we were selected as the key electrical/I&C subcontractor.

PRIMEX acted in the critical role of providing engineering, installation and commissioning the new system. Included in this project was a walk-in control “e-house” controlling the treatment plants main switchgear medium voltage breakers. This control panel was the first of its kind at the time it was done; PRIMEX used 3 miles of wire in the construction. Additional items that were provided included PLC control panels, UPS panels, Motor Control Centers and various instrumentation.

As part of the complete integration services provided, PRIMEX was tasked with overall system documentation which included a comprehensive description of operation and overall system commissioning. The owner opted-in for a witnessed factory acceptance test where PRIMEX flew the lead engineer to the PRIMEX facility and as a collaborative effort, every single termination was tested over the course of four days. The engineer was impressed with the PRIMEX craftsmanship and left satisfied.

CARACTERISTICAS ESPECIALES

PRIMEX was selected to be a key part of this project because of prior successful projects for Denver Water. PRIMEX had proven the ability to do quality work on a timely basis and on budget. This project came in under budget due to value engineering, which has kept PRIMEX on their short list for 15 years running now.
