Project History
- Project Area was identified in the 1995 Wastewater Master Plan
- Construction of the Miami Trails Wastewater Treatment Plant upgrade was completed in September, 2001
- Engineering Contract to design sanitary sewers was executed September 16, 2003
Five
Project History (continued)
- Public Involvement Meeting held January 11, 2005
- On February 23, 2005, a letter addressing comments & questions from the January 11, 2005 Public Involvement Meeting was mailed to property owners
- Citizen initiated petition March 2005 indicating no interest in centralized sewers
- On-Site Sampling began in Spring of 2005 and was completed early Summer of 2005

Study Design
- Windfield Hills/Winding Woods Subdivision
- Analyzed samples for CBOD5, Suspended Solids, Fecal Coliform, and Ammonia
- Compared results to OEPA and CC GHD Criteria
Eight
Study Design
- CBOD5 ? Measure of Organic Matter present in sample.
- Suspended Solids ? Aesthetics of Bathing Waters, Drinking Water Palatability.
- Fecal Coliform ? Indicates Bacterial Contamination & potential Human Health Risks.
- Ammonia ? Toxic to Aquatic Life.
High Concentration of any Parameter indicates a noncompliant System

- Field Crews encountered both individual discharges and collector lines.
- Parcels identified with a collector line assumed the same values as the sampled site. These are ?inferred? sites. (hatched area on maps)
- WH/WW: 76 sites sampled, 47 inferred (78%).

Fourteen
- Homes with non-discharging systems.
- Field crew unable to locate discharge.
- System not discharging when crew was present.
- No buildings on the property.

Clermont County Health District
- Why has my subdivision been chosen to have sewers extended and not a different one?
- What are the health issues and how do they effect me?
- If there is a significant health threat why hasn?t something been done before now?
Twenty-Four
Onsite Systems
- Why can?t the Board of Health increase monitoring to ensure properly working systems in lieu of connecting to sanitary sewers?
- Could we improve or replace our existing systems?
- Mounds, mounds and more mounds.
Twenty-Five
Wisconsin Mound Construction
Twenty-Six
Millennium Mound Construction
Twenty-Seven
Glendon Bio-Filter Construction
Twenty-Eight
Replacement considerations
- Cost - $18,000 to $22,000
- Maintenance-Service Contract of $250 to $350 per year.
- Large portion of yard rendered unusable for other activities or out buildings/pools.
Twenty-Nine
Why can?t I just do nothing?
- This subdivision and other Aerobic Treatment Unit subdivisions have been considered areas that needed to be sewered since sampling of these systems was conducted in the early 90?s. Now that sewers have become available for a more reasonable cost than onsite replacement, the health threat these systems pose can no longer be ignored.

Regulatory Mandate
- Federal & State laws require that any discharges of pollutants to waters of the state be regulated under the National Pollutant Discharge Elimination System (NPDES) permitting program.
- Home Sewage Treatment Systems (HSTSs) are not exempt from these laws.
Thirty-One
Regulatory Mandate
- In December, 1999, U.S. EPA issued regulations geared at controlling discharges & protecting water quality associated with polluted storm water from various urbanized areas (Phase II communities).
- Phase II communities will be required to identify and eliminate illicit discharges to their storm water systems.
- HSTSs are considered illicit discharges if they are not properly permitted.
Thirty-Two
Regulatory Mandate
- A general NPDES permit can be issued in situations where there are a class of similar discharges that, when operating under the terms of the permit, have a minimal impact to the environment either individually or as a whole.
- The general NPDES permitting program provides the only practicable means for providing NPDES permit coverage for Ohio?s HSTSs.
Thirty-Three
Regulatory Mandate
- The HSTS general NPDES permit will limit the number of discharging systems by allowing them only when they are the only feasible option for a residence.
- Phase II communities will be required to eliminate discharging HSTS?s when possible by installing central sewers or switching to non-discharging systems.

Centralized Sewer Estimated Costs
- Tentative assessment of $10,107 per parcel (can be assessed to property tax)
- System Capacity Fee & Permit Fees totaling $2,315 (paid by property owner at time of connection)
(continued)
Thirty-Six
Centralized Sewer Estimated Costs (continued)
- Cost to connect structure to the sewer lateral and abandon on-site system
- Sewer bill is determined by water usage, minimum bimonthly sewer bill is $23.75 (based on 5,000 gallons of water used)

Future
