Since 2001, Barr has been providing engineering assistance to the City of Beaver Bay, Minnesota, for its water and wastewater-treatment systems. Recently, the city called on us to design a renovation and upgrades for its water-treatment plant, which was built in the 1950s and last upgraded in the 1980s. The equipment and building were beyond their useful life and repair parts for some of the equipment were becoming difficult to obtain.

Barr designed process improvements, including new intake and high-service pumps, a packaged gravity clarifier/sand filter treatment system, and a chemical addition system. Our final design also included demolition of the existing building and other ancillary features; expansion of the existing building footprint; and upgrades to building mechanical and electrical systems, instrumentation and controls, and site work that included final grading, paving, and seeding.

We also assisted the city with the bidding process, provided construction observation, and worked with the contractor, the Minnesota Department of Health, and the city to provide safe drinking water to residents throughout the construction phase.

Beaver Bay now has a new water-treatment plant with equipment and controls that should last for decades, along with extra space designed to accommodate an additional filter system if demand increases.
