City of Nampa and Brown and Caldwell recognized with multiple awards

 
WALNUT CREEK, Calif., April 17, 2019 — The City of Nampa and Brown and Caldwell today announced receivership of two regional honors for infrastructure improvements undertaken at the City of Nampa’s Wastewater Treatment Plant (WWTP).

Awarded project of the year (over three million dollars category) by the American Public Works Association Rocky Mountain Chapter, and 2019’s best water/stormwater project by the American Council of Engineering Companies Idaho Chapter, Nampa’s WWTP Project Group A was hailed a best-in-class solution in meeting nutrient removal and water quality requirements.

To upgrade the Nampa WWTP and adhere to recycled water phosphorus and temperature federal regulations, the City embarked on a wastewater program in 2009 to set a course for its wastewater future. Early in the program, phasing of upgrades to the WWTP was recognized as the most flexible solution in determining the program’s future direction. In 2013, the City proceeded with phase I upgrades at the WWTP. Project Group A (PGA), which included upgrades to the liquid stream process, was the first project in phase I.

In addition to a new primary effluent pump station, modifications to two existing aeration basins and construction of a third, an innovative biological phosphorus removal system was incorporated to meet stringent nutrient removal requirements. Enhancements at the WWTP were also designed to accommodate increased capacity in response to population growth. The City collaborated with a multidisciplinary team consisting of Brown and Caldwell (program manager), Jacobs Engineering Group (design engineer), and The Ewing Company, Inc. (general contractor) to deliver the award-winning improvements by September 2018.

PGA not only addressed the City’s near-term regulatory requirements, but it also set the stage for future wastewater program direction. The design was developed to allow flexibility in achieving both future phosphorus and nitrogen reductions, preserving the City’s opportunity to pursue a regulatory-compliant recycled water program.

"The vision and direction from initial concept through project funding and construction ensured a best-in-class solution to the City’s nutrient challenges,” said City of Nampa’s Deputy Public Works Director Nate Runyan. "Additionally, Project Group A has resulted in substantial removals of a key nutrient from Indian Creek and the Lower Boise River, creating visible improvements to water quality. This exceptional project will serve the citizens of Nampa well into the future.”
