When the City of Warren faced aging equipment at its water pollution control center and seven pump stations, along with the need for expanded treatment capacity, B&N was engaged to develop a comprehensive Capital Improvement Plan (CIP). The city sought a clear roadmap to update critical assets, improve process reliability and increase capacity from an average flow of 16 MGD to 20 MGD and peak hourly flow of 40 MGD to 60 MGD.
A Collaborative, Data-Driven Planning Approach
B&N evaluated facility conditions, identified priority needs and explored alternatives for long-term improvements while working closely with the city through a series of technical workshops. The team used BioWin modeling to simulate existing plant performance and predict how proposed upgrades would support treatment goals, helping the city make informed decisions.
Phased Improvements to Address Urgent Needs and Long-Term Capacity
To allow the City to address immediate issues while planning larger upgrades, B&N structured the CIP into four phases.
Early Action Project highlights:
- Replacement of primary clarifier equipment
- Replacement of four primary sludge pumps
- Installation of density current baffles to Final Clarifiers
Phase 1 improvements included:
- New septage receiving unit
- Replacement of influent screens and construction of a new Screen Building
- Primary settling and sludge pumping improvements
- Aeration tank influent gate replacement
- Final clarifier refurbishment
- Electrical upgrades and SCADA system development
- Refurbishment of the Main Pump Station and installation of a new 42-inch force main
- Refurbishment of the South Leavitt Pump Station
B&N provided construction administration services for the Early Action and Phase 1 projects, helping the city manage quality, schedule and technical compliance.
Next Phase of Upgrades Supports Reliability and Regulatory Compliance
Phase 2 design includes improvements to grit handling, aeration and disinfection systems, along with new sludge holding and gravity thickening tanks, electrical enhancements and pump station refurbishments at the Youngstown and Parkman Road stations.
Strengthening System Performance for the Community
Through this multiphase CIP and collaborative planning process, B&N is helping the City of Warren strategically reinvest in essential infrastructure, reduce treatment deficiencies and position the wastewater system for long-term reliability and regulatory compliance.
