Project Detail

A new Arkansas state law, Act 197, passed in 2011 requires water systems that serve 5000 or more people to maintain a level of fluoride in drinking water to prevent tooth decay.

In response to the new law, the Carroll-Boone Water District (CBWD) began the planning process for installation of fluoridation facilities for the two existing treatment plants, and asked McGoodwin, Williams & Yates to prepare a Preliminary Engineering Report (PER) to evaluate alternatives and recommend necessary improvements. The PER was followed by detail design of the new facilities and construction services.

MWY recommended two separate feed facilities to enable the continued flexibility of operating two independent water treatment plants.

This approach allows for addition of fluoride into to the clearwells. Storage capacity for finished water in the clearwells will buffer against variation in fluoride concentrations in the finished water. Injection into the clearwells also allows for sampling of finished water for measuring fluoride before the finished water is pumped to the distribution system.

CBWD supplies treated water to Carroll and Boone Counties. The cities of Eureka Springs, Berryville, Green Forest, and Harrison are the primary customers served by the district. CBWD’s treatment facilities consist of two separate water treatment plants, both of which MWY designed.
