way
8. Public Input for PlanPublic Input for Plan
• Public input included:
• 2 community telephone surveys

meetings devoted to the Long Term Control Plan
9. Long Term Control Plan –Long Term Control Plan –
ContentsContents
• Actions – projects or
programs
• Schedules – when
projects will happen
• Where – locations where
projects will be
constructed
• Costs – project
expenditures; financing
plan
10. ObligationsObligations
• The consent decree requires that the LTCP
evaluate a range of CSO control alternatives
based on:
• Pollution reduction benefits
• Instream water quality conditions
• Construction and operations costs
• The consent decree requires that work included
in the plan be completed by August 31, 2016
12. Existing ConditionsExisting Conditions
• Currently 32 overflows
• 17 square miles of CSO area
• Discharge 33 times per year
• Discharge 625 million gallons per year
13. CSO Control Work has beenCSO Control Work has been
PerformedPerformed
• The City constructed three major tunnel systems
to store excess flow
• The City has implemented a number of sewer
separation projects to build separate sewer
systems
16. Alternatives ConsideredAlternatives Considered
• Flow storage and/or treatment
• Storage basins and tunnels with screening and other
treatment capability
• Sewer Separation
• Construction of new sewers for eliminating
combined systems
• Flow reduction/rerouting
• Small-scale measures to reduce the amount of flow
to the sewer system
17. Recommended PlanRecommended Plan
• Proposed Plan
• Reduces number of overflow locations
from 32 to 23
• Reduces frequency from 33 to 4 (untreated)
• Reduces volume from 625 MG/year to 144 MG/year
• Reduces typical pollutant discharge by 86%-89%
• Reduces bacterial discharge by 90%
18. Recommended PlanRecommended Plan
• Includes 26 projects
• Estimated cost of over $250M (2005 dollars)
• Reduces Ottawa River discharge to 2 times/
year
• Reduces Maumee River discharge to 4 times/
year
• Reduces Swan Creek discharge frequency to 3
times/year, disinfects the discharge that does
occur
24. Selected Control MethodsSelected Control Methods
• Storage basins
• Storage pipelines
• Optimization of existing tunnels
• Addition of disinfection capabilities to tunnels
• Flow reduction
• Sewer separation
25. Storage Basin ExamplesStorage Basin Examples
• Vast majority of work is
below ground
• Will require above
ground building for
support facilities
• Takes about 2 - 3 years
to construct
Birmingham CSO basinBirmingham CSO basin
Leib Screening/ DisinfectionLeib Screening/ Disinfection
Facility - DetroitFacility - Detroit
26. Storage PipelineStorage Pipeline
• Essentially large sewer
underground that will
provide storage volume
• Small support building
required in vicinity
• Takes 1 – 2 years for
construction
27. Expected Facility LocationsExpected Facility Locations
• Storage Basins
• Joe E. Brown Park OR Windermere Blvd.
• I – 280 / Front Street interchange area
• Private property at Oakdale and Miami
• City property next to I-75 on north side of Maumee
River
• Storage Pipelines
• International Park
• Adjacent to Jamie Farr Park
28. Tunnel ImprovementsTunnel Improvements
• Improve tunnel hydraulics to reduce frequency
• Reduce flow area (Swan Creek South)
• Improve cleaning, other operations items
• Add disinfection capability
31. Project CostsProject Costs
• All costs are based on 2005 cost index
• Actual costs at implementation will be impacted
by the rate of inflation and the final project
design
• Estimated overall cost: >$250 million
• Rates will be impacted by timing of projects and
financing method uses
32. What is Next?What is Next?
• Plan was submitted in draft form to USEPA
• Conference call held with USEPA this
afternoon
• Report submittal delayed until December 16,
2005 at EPA request
