DescriThe City of Toledo is implementing its multi-year Capital Improvement Program (CIP) based on the City’s 20-Year Master Plan and Needs Assessment approved by the Ohio EPA in 2016.  The existing 78-inch (steel) and 60-inch (prestressed concrete) raw water transmission mains carry raw water approximately 9 miles from Lake Erie and the Low-Service Pump Station (LSPS) to the Collins Park Water Treatment Plant.  The Plant treats the raw water for distribution to over 500,000 customers in Toledo and the surrounding region.  The 78-inch transmission main was originally installed in the 1940s and the 60-inch main was installed in the 1960s.  Investigations completed in April 2023 identified significant deficiencies within the existing 78-inch raw water main, including leaks, internal/external corrosion and misaligned joints.  Based upon a detailed evaluation of alternatives to best manage this situation, replacement of the 78-inch Raw Water Main along the same route as the current water mains is recommended.ption text goes here

The Collins Park Water Treatment Plant currently produces an annual average of approximately 70 million gallons per day (MGD) of finished water.  The maximum-day finished water production is approximately 110 MGD.  The total rated treatment capacity of the Collins Park WTP is 140 MGD with one treatment unit out of service.  The total peak capacity of the facility is 160 MGD with all treatment units in service.  Significant additional capacity is not anticipated to be required in the foreseeable future.

The City and its consultants analyzed several raw water main replacement and rehabilitation options including multiple alternative alignments, pipe materials and construction methods.  Installing a new  raw water main will provide an anticipated service life of up to 100 years and enables the existing raw water mains to operate at full capacity during construction.  In contrast, rehabilitation of the 78-inch raw water main would require removing segments of the system from service for extended periods of time, resulting in less capacity in the system and a limited service life (30 or fewer years) upon completion.

Preliminary phases for technical services of the project will be funded through the existing water rates, with the largest portions for detailed design and construction funded through a combination of grants and low-interest loans pursued by the City of Toledo and Regional Water Commission.  Additional information related to project funding will be provided in the future.

No.  The proposed Raw Water Main will be constructed within the existing easements through the Envirosafe parcels that pre-dated the construction of the facility.  The existing raw water main easement is located between two inactive landfill cells and protected by extensively constructed engineering controls and monitoring systems. Design of the new raw water main will incorporate modern construction techniques, defined materials, extensive quality control and additional monitoring capabilities to ensure long-term protection of the new and existing raw water mains.

The recommended route for the new raw water main will follow the same alignment as the existing 78-inch and 60-inch raw water mains.  The City and consultant team found limited opportunities for alternative routes due to significant residential and industrial growth throughout the City of Oregon and Jerusalem Township. Additional field work, including soil borings and sampling, will be completed during the Preliminary Design Phase in fall 2024/winter 2025.   Additional detailed analyses will continue to ensure an optimal design for construction and long-term resilience.

The City and the Project Design Team will prepare maintenance of traffic (MOT) plans in collaboration with the City of Oregon, Lucas County Engineer’s Office, Jerusalem Township and other project stakeholders.  The detailed MOT will include the anticipated timelines and milestones for construction of individual project phases, define haul routes to minimize impacts to adjacent and nearby landowners and businesses and establish protocols for outreach and communications during construction.

Opportunities and protections will be afforded to impacted property owners, as outlined within the Ohio Revised Code.  As the design progresses, the City may approach individual property owners for the purchase of easements required to implement the final recommended construction plan, including potential crop damage.

Field work for detailed surveying and geotechnical investigations will be coordinated with individual landowners to avoid entering the areas prior to harvest.  Specialized equipment using tracks to minimize potential soil compaction will be used for the soil borings and survey will be completed by aerial drones and foot traffic.  Future impacts due to construction activities will be negotiated with individual landowners. 

Detailed surveying, design and geotechnical investigations are currently underway and should be completed  in the second quarter of 2025.  The City and Design Team plan to share 30% complete design plans with the public in spring 2025 to request initial feedback and input to refine the proposed design.  Detailed design and funding applications will occur through 2025 and construction is anticipated to commence in 2026. 

While potential outages cannot be totally mitigated, efforts to minimize potential outages include extensive due diligence and coordination with local and regional service providers during design development.  Locations of known aerial and buried utilities will be shown to the extent possible within the design documents and specific areas requiring “daylighting” of some buried facilities will be denoted on the plans.

The City of Toledo and the Design Team, led by Jones & Henry Engineers, will continue to refine the proposed preliminary and detailed designs.  As the detailed design progresses, the Project Team will coordinate with regulatory agencies and secure required permits.  The City of Toledo will concurrently finalize funding sources and continue easement negotiations.

Yes.  The Project Team, consisting of the City of Toledo, Regional Water Commission and Jones & Henry Design Team, will meet periodically with individuals, organizations and the public to share progress and obtain stakeholder feedback.  Three public open house meetings are planned during design development to share 30% and 90% complete designs and final proposed construction plans.  The first open house is anticipated to take place in the second quarter of 2025.
