    1. The Feasibility of Vacuum Sewer Implementation In Venice, Italy Martin Felices, Lauren Goodfellow, Jay Johnston, Sonali Maheshwary Advisors: Prof. John Zeugner, Ing. Fabio Carrera Sponsor: Alan Hassett, Oak Hill Company Ltd.

    2. Purpose of the Study To examine the feasibility of implementing the HIFLOTM vacuum sewer into the historical and marginal areas of Venice. To collect data and gather information about vacuum sewer implementation in Venice. To determine feasibility on a cost, applicability and social impact level.

    3. Current Sewerage System Components Sedimentation tanks located within house foundations separates the light and heavy sewage Collettori large brick or cement troughs run underneath the streets Sbocchi sewage outlets located along the canal walls

    4. Fognature Design

    5. Current Failures of the Sewerage System in Venice

    6. Plan of Renovation City is divided into two areas Repairs spanned over a duration of 23 years Estimated cost: £ 818 billion

    7. Vacuum Sewers

    8. HIFLOW TM Patented by Alan Hassett High-tech features -Shallow pipelines -Air tight -High-lift -OTS hardware

    9. Section Breakdown

    10. Test Sites Santa Maria Formosa Model for upscale Historical area Residential with some tourism Santa Marta Request of the city Residential

    11. Option 1 Vacuum piping within the canals surrounding the entire island

    12. Option 1 (continued) Interfaced at sbocchi where collettori decant into canals

    13. Option 2 Vacuum piping alongside the collettori Sewage valves placed at interceptor points as manholes in the streets

    14. Option 3 Vacuum piping goes up underneath the house foundations Sewage valves placed in the sedimentation tanks

    15. Santa Maria Formosa Schematics

    16. Santa Maria Formosa Chart

    17. Santa Maria Formosa Costs

    19. Santa Marta Chart

    21. Upscale Implementation Water consumption is equivalent to the sewage flow Collection tanks range from 13,000 to 20,000 liters 24 collection stations placed accordingly

    22. Cost Analysis of Upscale Implementation

    23. Social Impacts Survey feedback The sewerage system is failing (69%) Sewage treatment is desired (82%) A slight increase in noise would be acceptable (62%) A raise in taxes is opposed (77%)

    24. Relay Network System Piping terminates at Ferrovia and Stazione Marittima Ready to be pumped out of the city Total cost for network: £57 Billion Designed for worst-case scenario

    25. Pumping off of Venice

    26. Conclusions

    27. Conclusions (continued) Option determination matrix was made Total costs:

    28. Recommendations for Further Study Relay network within Venice Pumping sewage to the mainland
