Wood County Economic Development Water Source Evaluation Study Phase I and Phase II Study Review NWWSD Public Meeting February 15, 2018 Jack Jones, P.E. Poggemeyer Design Group
Purpose Summary Phase I Study To protect the economic development interest of Wood County and its citizens that are currently served public water produced by the City of Toledo. To determine if feasible alternatives are available to serve Wood County customers currently supplied with a Toledo water. If so, are the alternatives cost effective. Could the alternatives be physically and politically achieved. Conclusion Cost range would be $40.57 to $42.92 per 1000 c.f. with no grant funding This is a competitive rate to the proposed Toledo Rate
Summary Phase I Study Evaluated: City of Bowling Green WTP Bayshore Power Plant WTP Maumee River WTP (Various Intake Locations) Costs for improvements were to be paid by NWWSD and Perrysburg. The most feasible concept was a City of Bowling Green water supply. The primary potential users were: City of Perrysburg NWWSD
Previous Phase I Report Summary Alternative Users: City of Maumee Village of Whitehouse Henry County Water District Minimum Costs: Maximum Costs: $134 Million to $151 Million $233 Million to $252 Million
Benefit Analysis City of Bowling Green WTP Expansion: Existing Operation Staff Least Capital Cost Expandable Technology Membrane Shared Process Benefits City of Bowling Green Cooperation/Benefit Existing Customer Service Agreement
Benefit Analysis New Bayshore Power Plant WTP: Purchase After Closure Issues Existing Unlimited Source Supply Lake Erie All New Operating Staff Longest Transmission Mains Routes Source Water Quality Concerns Storm Activity Small Backup Reservoir - Recommended
Benefit Analysis New Maumee River Supply WTP: Potentially Closest to Area to be Served Most Problematic Area for Reservoir Siting All New Operating Staff New River Intake Controversy (Potential) Most Urbanized Development Shortest Transmission Main Routes
Evaluation of Alternatives All three primary alternatives proved feasible for implementation; however, the alternative that has the least probable implementation risk factors is the City of Bowling Green WTP Expansion. These risk factors include: Land Availability/Costs Utility Conflicts/Existing Systems Neighborhood Opposition Political Cooperation Environmental Permitting/Approvals Agency Review/Support Cost Variations/Funding Easier Implementation
Previous Phase I Report Summary Project Improvements City of BG Alternative WTP Expansion (13.29 21 MGD) (Recommended) Reservoir (60 90 Days) Raw Water Transmission Line Transmission Supply Mains Booster Pump Station/Storage Next Step Intergovernmental Agreement Negotiations Completed August 2016
Phase II Study WCEDC decided to complete a Phase II Study to refine concepts and probable capital and operating costs based on the City of Bowling Green source supply and include the City of Maumee service area along with the City of Perrysburg and NWWSD service areas. Currently, the City of Toledo and its current contract communities continue to negotiate for the creation of a more equitable Regional System.
Purpose Phase II Study A. More in-depth study of the Bowling Green WTP expansion. B. Reviewed the wholesale rate and what debt is included in the rate. C. Reviewed the alternatives for reservoir construction and opted for two 150 to 200 acre reservoirs, one within one mile and a second within two miles of the WTP. D. Proposed, hydraulically modeled and evaluated advantages and disadvantages of three transmission main route concepts to provide service. E. Refined the transmission mains, reservoirs and WTP expansion costs. F. Adjusted the probable bulk water rate at the point of service based on the Bowling Green wholesale rate and refined project costs.
Results of the Phase II Study A. Transmission main route costs were refined and vary from $42.4 Million to $50.4 Million. B. The WTP and reservoir costs were refined to $104.9 Million for 23.49 MGD. C. The City of Bowling Green funds the $104.9 Million in the wholesale rate calculation. D. This current wholesale rate would be adequate to fund the new debt and operating costs at $27.13/1000 c.f. plus a monthly meter charge estimated at $8,345/month. E. The additional transmission debt and operational costs adds an estimated $8.55/1000 c.f. F. The final costs for the bulk water to the point of connection is estimated at $35.94/1000 c.f. (Lower than Phase I Study Estimate due to Maumee Inclusion)
Benefits of Bowling Green Service Higher pressures at WTP 95 psi. Additional topographic influence for 12 to 21.5 psi. Peak capacity of WTP = 21 MGD to 24.3 MGD (23.59 MGD Used). Could provide service without existing entity pumping facilities. Provides additional benefits to the City of Bowling Green: More treatment flexibility More reservoir capacity More transmission redundancy Lower per unit of treatment operating costs Maintain redundant Toledo connections for emergency conditions.
Phase I Phase II Comparison Phase I Study Phase II Study Did Not Include Maumee Cost to Serve without Grants $40.85/100 0 c.f. Smaller transmission mains without Maumee Evaluated only one Primary Route Costs Min: $134 - $151 M with Maumee Max: $233 - $252 M with Expanded Area Capacity 21 MGD Summer Includes Maumee Costs $35.94/1000 c.f. Requires larger transmission mains to include Maumee Multiple alternative routes made more sense with Maumee Service Costs $147.3 - $154.3 M with Maumee Capacity 23.59 MGD Summer
Summary NWWSD, Perrysburg and Maumee have a potential cost effective option to Toledo Water if developed jointly with a City of Bowling Green WTP expansion. The City of Bowling Green would still own, operate and maintain the facility. Bowling Green has proved to be pro-regional in its wholesale agreements in approach and methodology realizing the benefit of its regional partners in its own operations. With the Bowling Green Alternative, there could be some limitations on large volume future prospective water users when compared to the Toledo connections and WTP capacity.
Summary The economic benefits of the Bowling Green Connection would need to be recalculated if the District Perrysburg Maumee cooperative purchase is modified by one or more of the entities determining reduced interest. The TAWA Agreement continues to develop positively, if all entities agree and are supported by their respective legislative entities.
