20 mgd water treatment plant, expandable to 30 mgd
New Construction
2 years, 3 months
  • Improved wastewater quality with three clarifiers/thickeners

  • Plant can handle 30 mgd flow during peak demands

  • Project created jobs that help bolster Kentucky economy.

After decades of dealing with water scarcity issues related to regional droughts and supply deficits, the largest investor-owned water utility in the Bluegrass State turned to Gannett Fleming. On behalf of Kentucky American Water, we conducted a water supply study and determined the best solution to help rectify the state’s diminishing water resources was a new, high-powered treatment plant with a 30 million-gallons-per-day (mgd) capacity. As a result, Gannett Fleming designed the fully automated Kentucky River Station (KRS) II Water Treatment Plant with a rated capacity of 20 mgd, expandable to 30 mgd.

An incredibly efficient plant, KRS II uses fewer chemicals to treat water. Integrated with a dual electrical distribution network, the plant’s supervisory control and data acquisition (SCADA) system determines the appropriate chemical dosage, enhancing water quality and enabling one operator to run the plant. As a result, KRS II automation makes a positive impact on KAW’s triple bottom line – environmental, community, and fiscal responsibility.

What We Did

As engineering consultant, Gannett Fleming designed KRS II to include state-of-the-art components. The plant features high-rate plate settlers and process treatment components ranging from rapid mixers, horizontal reel flocculation, and clarifiers to mixed-media dual cell filters. Equipped with a dual-media filtration system, the plant’s chemical treatment process has exceeded Kentucky American’s water quality goals.

Facilities include a chemical building, sludge dewatering building, effluent plant pump station, clearwell, and laboratory where raw water and finished water quality is measured. Our responsibilities included civil, structural, architectural, instrumentation, electrical, mechanical, and stormwater and erosion control design; environmental permitting; bid and construction support; and an operation and maintenance manual.

Key Features

  • Designed four high-rate plate settler clarifiers improve water quality

  • Implemented gravity media filtration system with room to grow

  • Programmed SCADA system to be run by one plant operator.

Sustainability Features & Outcomes

  • Decreased chemical use and fuel consumption minimizes carbon footprint impact

  • Lessened environmental impact during construction by following existing routes when installing transmission main.

Awards & Recognition

  • Grand Conceptor Award, 2013, ACEC Kentucky, Engineering Excellence Awards Competition.
