HDR/Kalispell AWWTP Fermenter Rehabilitation ProjectwMA JAL. r KALISPELL WORKS act MINI 1 FYZ April 29, 2021 Susie Turner, PE Director of Public Works ` 201 First Avenue East r Kalispell, Montana 59901 RE: Request for Qualifications for Kalispell AWWTP Fermenter Rehabilitation Project Dear Susie and Selection Committee Members: Without a doubt, the fermenter is critical to the successful operation of the wastewater treatment plant and meeting effluent phosphorus limits. As a result, the condition assessment and development of alternatives for rehabilitation must be accomplished by a team that not only has extensive experience on similar projects, but also has an intimate knowledge of Kalispell's treatment facility and operations. As demonstrated by the enclosed qualifications, we provide the most qualified team possible, offering strengths key to the condition assessment of the fermenter, delivery of bid documents that contain appropriate rehabilitation methods, and construction management services. The key benefits of our team include: • Extensive Knowledge of the City's Facilities and Needs. Our knowledge of the City of Kalispell's wastewater treatment plant and process operations is unmatched. HDR's previous work on the design and construction of the fermenter, our first condition assessment of the fermenter, and considerable time spent with operations staff gives our team a unique understanding of the challenges the City is facing. We have already thought through potential solutions so that we can quickly advance rehabilitation methods following the completion of the second condition assessment. • Unique Experience with Similar Projects. We have assembled a team of professional experts uniquely qualified in the condition assessment of wastewater treatment facilities. The Kalispell AWWTP fermenter has a very distinctive and corrosive environment, which requires specialists to evaluate existing concrete, perform a structural evaluation of metal components, and consider possibilities for protective coatings failures. Our experts have the experience required to perform those evaluations and provide a plan for rehabilitation of the fermenter. In addition, we have unique experience utilizing destructive and nondestructive techniques for assessing the condition of the various fermenter components and a proven field team for inspection and testing of protective coatings. A comprehensive understanding of the issues above is critical to the development of long-term and cost- effective solutions. Successful rehabilitation of the fermenter is required to maintain the exceptional AWWTP performance that the City has consistently achieved for decades. We believe our past results are indicative of our future performance. We look forward to continuing our partnership with you on this critical rehabilitation project.

As was typical for the time period the primary digester was constructed with a fixed concrete lid and pumped mixing. The gas space under the lid is extremely corrosive with high concentrations of hydrogen sulfide and methane gas. Due to the highly corrosive environment the concrete lid had experienced cracking and spalding of the interior concrete. Gas leaking through the cracks in the lid was causing bubbles to form in the insulation membrane presenting a hazardous condition for operations staff and structural degradation of the lid had the potential for catastrophic failure. Mixing pumps were no longer manufactured making it difficult to find replacement parts. The purpose of the project was to inspect and evaluate the existing Primary Digester structural and mechanical components and provide the City with an alternatives evaluation; recommendations for rehabilitation repair and replacement; and final design and construction administration services of the recommended alternative. The selected alternative included removing and replacing the existing concrete dome lid with a cast - in -place concrete lid and top entry mechanical mixer. The interior of the digester lid was coated with a spray applied polyurethane coating designed for the harsh environment. The project also included new gas handling equipment and foam suppression.

CONTRACT UNDERSTANDING AND APPROACH NO Understanding The Kalispell AWWTP fermenter was originally constructed during the 2007-2008 Phase 1 Improvements Project. The primary purpose of the fermenter is to produce supernatant which contains VFAs utilized in the secondary treatment process to facilitate phosphorous removal. Primary sludge pumps convey sludge from the primary clarifiers to the single -stage fermenter. Sludge enters the 45-foot diameter structure through the side of the unit and discharges within the center well. The average pH concentration inside the fermenter is 5.5. The solids removal mechanism is picket fence style with a plow/ squeegee mounted at the bottom that pushes sludge to a sump located in the center of the fermenter. The fermenter sludge pump is used to convey sludge from a sump in the fermenter to the primary digester. Scum is collected from the surface of the fermenter and is pumped to the digesters. Fermenter supernatant flows over a launder weir to a buried concrete wet well. The fermenter supernatant pumps convey supernatant to the anaerobic zone of the bioreactors. The fermenter also has an aluminum cover and dedicated odor control fan for odor mitigation. Given the corrosive and harsh environment of the fermenter, protective coatings were applied to portions of the interior components and concrete surfaces. The one year warranty inspection revealed the coatings on the concrete were delaminating. The coatings were removed and completely re -applied after the one year warranty inspection. In July 2020, HDR performed a condition assessment on the fermenter to determine the condition of the concrete, concrete coatings, piping, hardware, equipment, launder, ventilation system, and access points. The fermenter was emptied and cleaned by the City prior to the assessment to provide HDR inspectors with a clean environment in which to perform observation and inspection activities. Inspection methods included visual and photographic Inspection and concrete sounding with a hammer. A summary of the findings is as follows: 1. Exterior aluminum components were in satisfactory condition. 2. Coating systems and the steel and concrete substrate were found to be in unsatisfactory condition.
