PROJECT

Design-Build Water Treatment Plant

Our team, including joint venture partner CAS Constructors, provided design-build services for a new water treatment plant in Bonner Springs, Kansas, that uses a membrane system for softening water. The new plant will produce up to 2 million gallons per day (MGD) of softened water, meeting the growing community’s needs and supporting potential future industrial development.

The new plant will use Greensand filtration for iron and manganese removal, paired with nanofiltration membranes for softening, which was selected over lime softening to reduce capital costs, improve operational flexibility and lower operation expenses.

The completed project also includes a new 520-gallons-per-minute water production well, transmission main and booster pump station serving the Lake of the Forest service area.

The technology selection was made after our joint venture team led a series of workshops comparing treatment methods, estimated construction pricing and life-cycle cost information. City representatives also toured a new water treatment plant in Arkansas City, Kansas, to see the Greensand and membrane treatment in operation, helping the staff understand the differences in treatment and O&M requirements.

"The Burns & McDonnell and CAS Constructors team listened to our needs and offered technical and budget-focused transparency and collaboration. It was apparent this was a team that had worked together before and was focused on meeting the needs of our organization. They helped us get to a final price and product everyone was happy with. Together, we are building the plant we want and need for our community."

The joint venture team was selected to bring the project to completion after a previous design-build team exceeded the agreed-upon budget at the end of its first phase. As the project progressed under our design-build contract, real-time cost and schedule updates were generated to guard against extreme market volatility.

We also submitted a second application to the State Revolving Fund (SRF), helping secure $2.5 million in funding and principal forgiveness associated with addressing emerging contaminants.
