Progressive design-build was selected by Aqua Ohio for upgrades to the 10 MGD Ashtabula Water Treatment Plant - a new flocculation/sedimentation facility and filter improvements. Completing the project on time was “mission-critical”; essential to meet regulatory requirements of the Public Utilities Commission of Ohio and Ohio EPA. This project was a ‘rate case’ project, meaning that recovery of the capital cost was only possible if it was constructed, commissioned, and treating water “on schedule” (by end of 2021). The Great Lakes Construction Co. – HDR team was selected by Aqua Ohio with a notice to proceed issued in May 2020, leaving only 19 months for preliminary and detailed design, construction, commissioning, and acceptance. With careful planning, continuous communication, and effective collaboration, this tight schedule was achieved. Cutover to the new facilities and control system was seamless and accomplished in less than half the time allocated, indicating the quality of the designed and constructed project and engagement of Aqua Ohio’s Engineering and Operations throughout. At all times during the construction period, reliable delivery of high-quality water continued to Aqua Ohio’s customers.
