2001
General Permit 4.02 after
2001
Why is this important?
Because there is an effluent screen

R18-9-A314 Design, Manufacturing, Installation.

14. Liquid Level- Normal 8C
Depending on the precast, levels will be different, by
the gallons, so you need to measure the level.
Most Important question on the form
Normal - Below Normal - Above Normal - Not Determined

15. Inlet Baffle with 2 inch drop at
invert of the inlet. Proper, but very
rare! R18-9-A314 1 f. 8 K I

16. Liquid Level at Outlet
Proper level-at invert of the outlet

17. Below normal
Fluctuating levels,Home is
occupied, this could have been
easily missed

18. Liquid Level-Above Normal 8G

19. Improper Level
Tank set to High

22. Compartments 8E
1989 2 compartment tanks

23. Septic Tank Risers 8G
What is the concern here?

24. Tank Depth 8 I
Air to Liquid Interface
Measure the level

26. Don’t be Fooled!!
If you can’t see sewage entering tank, be cautions!
This tank had a proper level at the outlet.

27. Clamshell
Obvious receding levels; this tank is leaking.

28. FOG

29. FOG Fat Oil Grease 6G
This would exceed typical Residential Sewage

Not Functional, essential to layering

33. WHY DO WE CARE ABOUT BAFFLES
Our septic tank pretreats the sewage, separates it
into layers, baffles are essential to this process.

39. Baffles or Sanitary T’s 8 J
Pre-cast concrete
What’s wrong here?

40. BAFFLES
OFF PLUMB
When we need to send a photo to the
customer to show then the issue with the
baffle, we place our measuring stick plumb.
You can see the degree it is off 90.
If it is not @ 90, there is a problem, it is:

41. YOU WILL FIND THIS.
DIPPED

42. Crimped

43. Severed at Tank

44. It can Function for Years,
without being noticed until soil around tank is saturated.

45. Exfiltration at Outlet Delivery 9B
Effluent not Reaching Disposal Works.

46. EXPOSED REBAR
Is there evidence of:
Root Invasion,
Cracks in the tank
Damaged lids,
Damaged Risers
Other

47. Exposed Rebar causes cracks, root invasion. 8
N other

49. CRACKS ON THE
BOTTOM

50. Evidence of: Cracks, roots, rebar, damaged
lids or risers. 8 N

51. Drain Flies
Diatomaceous Earth

52. DRAIN FLIES

56. Surging

57. Effluent Screen/Filter 8 P
Closed at Top

60. Theobacillus is the culprit

61. T Baffle acts as a smoke stack.

62. Disposal Works, Ettringite.

63. Billowing

65. Early Precast Septic Tanks
Flush to Lid

66. Billowing, HS Damage

67. Field Inspection Ports 9 E
How to measure ?
Ponding in Field?
Good or Bad?
