Bay View WWTP Final Effluent Pump Station

Overview

Ribway was selected by the City of Toledo as the prime consultant for engineering design and construction management services for the 232 million gallons per day (MGD) Final Effluent Pump Station (FEPS) at the Bay View Wastewater Treatment Plant (WWTP).

Project Scope

The FEPS includes:

• Effluent Pumps: Five vertical axial flow propeller pumps, each rated for 53 MGD and 25 feet of total dynamic head (TDH). Three pumps are fixed speed, and two are variable speed, powered by 460 V, 3-phase, 300 HP motors.
• Wet Well: A reinforced concrete wet well approximately 75 feet wide, 90 feet long, and 35 feet deep with individual pump bay walls.
• Piping: Suction and discharge piping of 42-inch diameter.
• Building: A structure housing electrical and miscellaneous equipment.
• Foundation: The wet well and building are supported on a deep piling foundation.

Objectives and Design

The pump station is designed to discharge treated effluent to the Maumee River during high river stages. Ribway conducted an extensive hydraulic analysis to ensure upstream process units were not compromised during operation. The station design complies with Hydraulic Institute Standards, and a full-scale model was built and tested prior to construction.

Construction Management

Ribway provided comprehensive services, including:

• Lead Engineering Design: Overseeing all aspects of the design process.
• Construction Administration: Ensuring the project adhered to specifications and timelines.
• Field Inspection: Monitoring construction quality and progress.
• Commissioning: Testing and validating system functionality.

The project was managed under the oversight of Black & Veatch, the program manager for the Wet Weather Treatment Program.

Timeline and Budget

• Design Completion: December 2005.
• Construction Completion: November 2007.

Results

The Final Effluent Pump Station significantly enhances the Bay View WWTP’s capability to manage treated effluent during high river stages. The facility operates efficiently while maintaining compliance with regulatory standards and safeguarding upstream processes.
