15 MINUTE BREAK 14. SludgeHammer & Infiltrator Ron Robinson-
Spoerr Precast Concrete 15. 20 systems currently in operation in
Van Wert County Enviro-Septic System Monitoring Program 16.
Post-installation system site visits 277 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
recent flow has been observed-11 Sites where standing water has
been observed in inspection ports- 10 A few more statistics 17.
Perimeter Drain Sampling 18. 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 Zero systems sampled during
2010-2011 season (as of today) 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. 19. 2008-2009 Sampling Results 20. 2009-2010
Sampling Results 21. Perimeter Drain Sampling
CONCLUSIONS
High suspended solids could be due to recently disturbed soil
around the drain
Bacteria results are very inconsistent
Comparison of results between curtain drain and system
inspection port suggestadditional factors influencing bacterial
content of drain effluent.
Hopefully more testing will help to provide a clearer picture,
BUT testing isscheduled to end in the spring of 2011.
22.
Perimeter drains dont flow as often as originally expected
Water appears to be very clean prior to entering soil
Data suggests that outside factors may be influencing quality
of perimeter drain effluent
Onsite systems can function in our heavy soils
What have we learned??? 23.
Current system monitoring program
Sampling will end in 2011
Visual monitoring will continue, with frequency based on each
systems history
Phase II
25 additional systems using same sizing criteria
Replacement installations only
Multiple water table monitoring wells to be installed on each
site to monitor seasonal water table under and around systems.
Whats next??? Typical water table monitoring well 24. Design
Plans and As-Built Drawings 25.
Design plan basics:
Clean, dark and legible drawing and print
Site layout drawing, approximately to scale
Relevant measurements*
-Distance from septic system to well, property lines,
surfacewater
-Dimensions of soil absorption area
-Designated benchmark which is identified at site
-Relevant elevations of system components and absorptionsystem
area
*Much of this information can be provided using a
designtemplate, rather than creating a very cluttered drawing
26. Site Layout Drawing 27.
As-built basics:
Clean, dark and legible drawing and print
-As-built drawing will become part of Health Departmentrecord
and will also be mailed to homeowner.
Site layout drawing, approximately to scale
-Site layout drawing from design plan may be used if nochanges
were made.
Signed statement indicating that the system was installed in
accordance with all applicable rules and plan specifications.
28.
As-built basics:
Make a rough sketch including all measurements and elevations
before leaving the job site.
Submit as-built drawing to health department as soon as
possible after installation is completed.
Remember, this requirement is expected to continue under
the new statewide rules.
29. Sample as-built drawing 30. Sample health department
installation record 31. Some Random Thoughts
In the off-season
Make sure all as-built records have been submitted to the
health department
Encourage prospective customers to arrange for site and soil
evaluations well before spring
Determine system locations and layouts
Protect future system locations using rope or caution tape
Compile and submit all required design information to health
department for site review
Continuing education
