Regional Wastewater Treatment Plant Improvements in Illinois

CHALLENGE

The Village of Frankfort operated three Wastewater Treatment Plants (WWTP): North, West, and the Regional WWTP. In March 2015, the Village completed a Facility Plan and opted to consolidate the North and West Plants into the Regional WWTP. The plan proposed increasing the Regional Plant’s capacity from a design average of 3.0 MGD to 4.67 MGD.

SOLUTION

To support the consolidation and capacity increase, HR Green was engaged to design and implement a series of critical improvements at the Regional WWTP. Key upgrades included:

• Odor Control and Mixing Tank Improvements
• Oxidation
• Tertiary Disc Filter and UV Disinfection
• Re-aeration Blower
• RAS/WAS Pump Station
• Sludge Storage

HR Green’s comprehensive design included process, hydraulic, structural, electrical, and mechanical elements. HR Green also provided construction services to oversee the installation of HR Green’s designed improvements as well as assisted with construction coordination across multiple projects involved in the plant consolidation.

BENEFIT

Through strategic design and skilled project management, HR Green helped the Village of Frankfort achieve a cost-effective solution that enhances wastewater treatment for years to come.
