City of Toledo City of Toledo Sewer SystemSewer System
• As indicated in the video, the City’s sewer system includes both separated and combined sewer systems
• Combined systems – carry both sewage and rainwater in the same pipe
• Separated systems – carry sewage and rainwater in separate pipes

ObligationsObligations
• The LTCP must evaluate a range of CSO control alternatives based on:• Pollution reduction benefits• Instream water quality conditions• Frequency of discharge• Construction and operations costs
![Page 11: LTCP Meeting 9-16-04](https://reader033.fdocuments.in/reader033/viewer/2022051513/545c71deaf7959af098b47ef/html5/thumbnails/11.jpg)

Consent Decree Consent Decree RequirementsRequirements• The Consent Decree requires the development of a
Long Term Control Plan for Combined Sewer Overflows (LTCP).
• A draft plan will be prepared by summer 2005.

CSO Regulations….CSO Regulations….
Call for:
• Control of CSOs
• New sewers to implement controls
• Reducing stormwater flow
• Systems to be properly maintained
• Minimizing CSO discharges
Do not call for:
• Elimination of CSOs
• Extensive replacement of the sewer system
• Improvements in drainage
• Control of basement backup
• Other actions that would improve water quality, that are not related to CSOs.
![Page 13: LTCP Meeting 9-16-04](https://reader033.fdocuments.in/reader033/viewer/2022051513/545c71deaf7959af098b47ef/html5/thumbnails/13.jpg)

Primary Issue #1 – Primary Issue #1 – Big Picture GoalsBig Picture Goals
• Big picture goals define the hoped for achievements of the project. The primary question relates to how residents want to be able to use the waterways.
• Depending on the type of alternative selected, additional benefits are possible. These include: improving the performance of the sewer system, and changed land use in the combined areas.
![Page 14: LTCP Meeting 9-16-04](https://reader033.fdocuments.in/reader033/viewer/2022051513/545c71deaf7959af098b47ef/html5/thumbnails/14.jpg)

Primary Issue #1 – Primary Issue #1 – Big Picture GoalsBig Picture Goals
• What is the balance that the public prefers in water quality versus cost?• Seeing a real change in
the waterways?
• Meeting the regulations at the lowest possible cost?

Primary Issue #2 – Primary Issue #2 – Types of AlternativesTypes of Alternatives
• Alternative selection is a combination of performance and suitability considerations. There are a number of types of alternatives.
![Page 18: LTCP Meeting 9-16-04](https://reader033.fdocuments.in/reader033/viewer/2022051513/545c71deaf7959af098b47ef/html5/thumbnails/18.jpg)

Principal AlternativesPrincipal Alternatives
• 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
![Page 19: LTCP Meeting 9-16-04](https://reader033.fdocuments.in/reader033/viewer/2022051513/545c71deaf7959af098b47ef/html5/thumbnails/19.jpg)

Storage / Treatment Storage / Treatment Basic InformationBasic Information
• Type of facilities: either concrete tanks or tunnels
• Type of treatment: screening (minimum), potentially disinfection
• Land area required: 3 – 10 acres• Typical siting locations: waterfront property,
parks, other vacant parcels near rivers• Other requirements: some sewer work to bring
flow to the site
![Page 21: LTCP Meeting 9-16-04](https://reader033.fdocuments.in/reader033/viewer/2022051513/545c71deaf7959af098b47ef/html5/thumbnails/21.jpg)

Storage/ Treatment Storage/ Treatment Facilities Pros and ConsFacilities Pros and Cons
• Pros• Most work is limited to one location and the
adjacent areas are not disturbed• Water is either stored (small storms) or partially
treated (large storms)
• Cons• Treatment generally requires construction of a
relatively tall building.• Construction activities are generally 2 – 3 years in
duration limiting the use of sites during that period.

Sewer Separation BasicsSewer Separation Basics
• Construct a new sewer to separate flow
• Generally requires 3 – 6 months to complete work on a street; 1 – 2 years to complete work in an area
• Generally doesn’t involve land acquisition
![Page 25: LTCP Meeting 9-16-04](https://reader033.fdocuments.in/reader033/viewer/2022051513/545c71deaf7959af098b47ef/html5/thumbnails/25.jpg)

Sewer Separation Sewer Separation Pros and ConsPros and Cons
• Pros• Upgrades the sewer system
• Eliminates CSO discharges
• Doesn’t require property
• Cons• May increase total load of pollutants to the
waterways• Disruptive to individual property owner

Flow Routing/ Flow Routing/ Reduction BasicsReduction Basics
• Reduces the amount of stormwater runoff generated by rerouting flows to site storage areas.
• Implemented on either a site specific or area specific basis
• Relatively long time implementation and generally dependant on voluntary participation.

Flow Reduction / Flow Reduction / Rerouting Pros and ConsRerouting Pros and Cons
• Pros• Addresses problem at the source
• Could be considered best environmentally
• Could reduce basement or surface flooding
