Kokosing Industrial Wins 2019 Build Ohio Award


The Associated General Contractors (AGC) of Ohio awarded Kokosing Industrial the esteemed Build Ohio Award in the Industrial/Heavy Category for the Dublin Road Water Treatment Plant Facility Expansion for the City of Columbus. The four-phase project included major upgrades to the existing facility and new infrastructure to increase processing capacity. The end result of the $188 million project is a state-of-the-art ion exchange and ozone treatment process with biologically active filters, and is the largest treatment plant of its kind in the United States.

The Dublin Road Water Treatment Plant (DRWTP) was originally built in 1975; its aging infrastructure and dated technology was ineffective against the nitrates that leach into water sources from fertilizers used in Ohio’s sizeable agricultural industry. A phased approach was applied to the vast amount of construction needed to provide higher-quality water to current residents and prepare DRWTP to handle the anticipated exponential growth for its service area. Plant operations are now much more cost effective and efficient.

  • Phase 1 consisted of construction to prepare the plant for the coming work, including a new sludge pump station with custom pumps, new electrical distribution system, new parking facility and sitework.
  • The entire 18-bay filter gallery was rehabilitated during Phase 2, including media and underdrain replacement. A new SCADA system was installed, along with new network switches, servers, and associated updates.
  • New recarbonation and ozone contact basins, with connecting channels and pipe systems, were constructed during Phrase 3.
  • A new ion exchange facility was constructed during Phase 4, which is the largest of its kind in the United States. Additional work included replacement of six high-service pumps, installation of over 1,125 valves and major electrical and HVAC upgrades.

This complex work provided our project teams with the opportunity to rise to difficult challenges and develop creative approaches to deliver a quality project to a valued client.

The Build Ohio Awards are based on the following criteria: excellence in project management, innovation in construction techniques and materials, excellence in client service and meeting the challenge of a difficult job.
