Innovative Solutions for Wastewater Treatment

Kokosing Industrial completed massive capital and process improvements to the City of Springfield’s Wastewater Treatment Facilities.

inside the project

The largest scope of the contract is a 100 MGD High Rate Treatment (HRT) facility that uses a compressible media filtration system. The HRT facility removes 85% of the total suspended solids. The HRT facility is the largest compressible media filtration system in the country. A new 140-foot diameter secondary clarifier increased the plant’s secondary clarification process by 10 MGD. An Excess Flow Interceptor as the Headworks was constructed to divert overflow to the new HRT. Additionally, a new 75-foot diameter digester, maintenance facility and upgrades to the screening and solids handling process all contributed to updating and modernizing this facility.

why it matters

Kokosing Industrial experts brought innovation to the project through the use of Building Information Modeling (BIM) – a 3D model to visualize the project and enhance project planning and sequencing. Several of the new structures were designed to intersect with existing pipes, which required a number of creative pipe shoring installations. Kokosing’s Central Engineering Group played an important role in the successful shoring of all pipe by providing BIM files of all piping throughout the facility. Some of the more challenging work items included heavy rock excavation, difficult pipe schedule, dewatering, and excavation of an abandoned landfill.

Kokosing’s level of detail, thoughtful planning, consistent communication and clear objectives have guided the project from day one.
