North Lake, MBR Treatment Plant

Challenged by explosive growth and the creation of a new resort community (Tamarack), the North Lake Recreational Sewer and Water District worked closely with Keller Associates in developing a treatment system that would meet the growing needs of a pristine recreational area.

Cost: $15,700,000

Services Provided:

• Keller Associates completed the quick-paced master planning and design services and provided construction support services through plant startup

Project Features:

• 1.25 MGD treatment plant entirely enclosed in a steel building to look like a rural area horse barn
• 45-foot-high steel building and frame used to support snow and wind loads and a multi-ton crane that moves throughout the building
• Masonry enclosures were used to isolate machinery and dampen noise
• Plant houses large concrete MBR tanks over 20 feet deep extending below the floor
• Complex concrete structures with multi-levels of suspended concrete work
• Moment framing was incorporated to provide unobstructed areas to house equipment and storage and allow open work areas and office space
