    4. Project Area

    5. Needs Assessment 153 of the 181 Parcels are served by an onsite sewage treatment. 130 of the 153 parcels have been inspected Of the 130 inspected parcels: 73 use a conventional septic tank system. 37 were unable to be classified 48 have failed at least once

    6. Needs Assessment Occurring Failures Standing water in vent stack of the drainage fields Backup of Sewage into buildings Seepage of sewage onto the surface of the ground Indirect flow of septage into surface waters Direct discharge of septage into surface waters

    7. Scope of Work Part 1 Preliminary Design Services Three Alternative Designs Evaluation of Environmental Impacts Evaluation of Cost and Constructability of Each Alternative. Recommendation of Final Alternative

    9. Three Designs Gravity Flow Pros Traditional Minimal Maintenance Mostly Non Mechanical Cons Topography requires lift stations Difficult to install Expensive to install Leakage and infiltration Will not be feasible for some of the terrain

    10. Three Designs Low Pressure System Pros Easy Installation Low Initial Cost Fluids within system will flow up a positive grade No infiltration Easy detection of leak Cons Residents Responsible for maintenance Requires mechanical devices to work Unfamiliar System

    11. Three Designs Mixed System Pros Fit appropriate system to any particular location Allows system to connect to areas with rolling hills. Cons Complicated to install Expensive lift stations Residential complaints

    12. Prelim Cost Analysis
