Presentation on Van Wert County's experience with the use of the Presby Enviro-Septic system as an alternative to conventional onsite sewage treatment systems. This presentation was given at a recent sewage treatment system contractor meeting in Richland County, Ohio.
37. Going Inside the Pipe Uncovering Enviro-Septic pipe after 6 months of use by a family of 3 System Monitoring Program
38. Going Inside the Pipe Inside of pipe 90’ from d-box System Monitoring Program
39. System Monitoring Program Random Observations Plant growing in dark inspection port ?? Vegetation patterns as an indicator of water movement
40. A few statistics… 19 systems currently in operation in Van Wert County System Monitoring Program
41. Post-installation system site visits 249 Systems sampled- 7 Sites where drain flow has been directly observed- 4 Sites where drain has been found backed up at sampling port- 5 Sites where no evidence of flow has been observed- 10 A few more statistics… System Monitoring Program
43. Perimeter Drain Sampling First systems began operating - fall 2008 First opportunity to collect samples – March 2009 Four systems sampled during 2008-2009 season Five systems sampled during 2009-2010 season System Monitoring Program Perimeter drain effluent testing is made possible by the financial support of the Van Wert County Foundation, Ohio Department of Health, and the Van Wert County Board of Health.
47. Lesson #1: A plastic dosing tank requires extra design and installation considerations. What have we learned???
48. Lesson #2: The small dose volume required by this system requires an alternative float configuration. What have we learned???
49. Lesson #3: Perimeter drain flow has been much less frequent than expected. What have we learned??? Some drains can be found flowing very soon after major rainfall, some have not been found flowing at all.
50. Lesson #4: System venting adds another variable when troubleshooting. What have we learned???
51.
52. Lesson #6: Testing data suggests outside factors influence makeup of perimeter drain effluent. What have we learned???
