Lebanon Correctional Institute WWTP Bar Screen Replacement

Ribway provided comprehensive design engineering, construction management, administration, and inspection services for the development of a pretreatment facility at a 1.5 MGD treatment plant. The facility was designed to address the issue of screenings and material overloading the fine screen on the downstream side of the treatment process.

Key Features

Facility Components:

• Building Construction:
  • 300-square-foot concrete block structure.
  • Roof supported by wooden trusses with asphalt shingles.
• Screening System:
  • Installation of a catenary bar screen to effectively remove debris.
• Unloading Station:
  • Roll-off container provided for collection of screened material.

Design and Construction Details

• The facility’s design aimed to optimize pretreatment efficiency by removing debris at the earliest stage of the process.
• Durable materials and simple structural components were chosen to ensure longevity and ease of maintenance.

Timeline

• Design Completion: May 2002
• Construction Completion: November 2003

Project Outcomes

• Improved operational efficiency by reducing overloading of fine screens downstream.
• Enhanced durability and reliability of the treatment process through robust facility design.
• Successful project delivery within the established timeline.
