address has been inspected and the following is known about the system. A
sketch of the known components of the system is available for most properties at
the Orono City Hall. �

Imminent Public Health Threat
Yes �No ,
If yes, please contact the Onsite Systems Manager at 952-249-4626 uTithin 10
days of receipt of this notice. The septic system must be broujht into compliance
w7thin 90 days. Failure to do so will result in referral to the City Attomey for
legal action.
System Identified as Non-Compliant
Yes �No
If yes, system must be brought into compliance by:
December 31, 2007 �

Septic Tank(s)Pump out Needed
Yes �No
The Cit��recommends the septic tank(s j and/or lift tanlc be serviced and pumped
out every three years. CitS-records indicate the tank(s) were last pumped out on
� ..Z ` - . The tank(s) should be cleaned through thz manhole and
not through the inspection pipes, tlus allows for proper cleanin�.

Dear Ms. Piepho:
An inspection of your septic system was conducted on May 22, 2000. A summary of the inspection
is below.
Septic Tank Condition
1. Pumpout not needed this year(last pumpout date 9/4/96).
The septic system is a compliant system, meaning it meets a11 or most cunent City and State
Standards. Enclosed is a list of licensed contractors who work in Orono on a regulaz basis. This
list is enclosed simply for your reference in case your septic system needs maintenance in the future.
Also enclosed is a fact sheet explaining your septic system and how it functions. Finally, an as-built
drawing is enclosed showing the approximate location of the septic system.
If you have any questions regarding this report, please contact me at the City Offices at 249-4600.

1 Code System: Meets or exceeds current City standards in all respects relating to design,
construction, and location. Appears to be operating properly.
2 Compliant System: Does not meet all current City standards for new construction, but in
most respects appears to be designed, located, and constructed in accordance with previous
codes and is functioning properly.
3 Non-Compliant System: System may or may not meet current City standards for design,
construction, or location, but is failing to properly treat and dispose of the current
input; and any system with less than three feet of vertical separation between the bottom
of the drainfield and the saturated soil level.
(The saturated soil level [t/] has or [ ] has not beea ideatified at this time. If the
saturated soil level has not been ideatified, this classification is subject to revision.).
TANK CONDITION (5-9) : 5
5 Pumpout not needed at this time.
Solids accumulation in tanks indicates they should be pumped out this year.
7 System is discharging to the surface. Tanks must be pumped out within 48 hours.
8 Inspection risers missing-tanks could not be inspected. If tanks have not been pumped out
within three years, they should be pumped out and risers installed now.
9 Inspection pipe is located over tank baffle-can not measure solids accumulation. If tanks
have not been pumped out within three years, they should be pumped out now.
(During the last septic tank Maintenaace Pux�pout the tanks [ ] were or [ ] were not confirmad

As yau requested on February 9, 197�. we have recently taken :
two power auser borings aad 12 �perc:olation tests to a�sist
in evaluating the soil, soi� absorptivity, and the ground-
water conditions for the ucsign of individual sanitary
systems for the proposcd houses to be situatad on tho above
referencea lots. The percolation tests and horings were '
taken in the general locations as directed by you and as
shown on the attached sketch. Surface elevations at the
bore holes were referenced to the center line of North AtcR
Road south of the southeast property corner of Lot S with
an assume� elevatioa of 100.0.

1977 using a truck•mounted powark;auge'��'uni�;.��he soii
classifications and depth s�s shown on the attaChed logs wOre
inferred from the soils brought to the suteface by the con-
; tinuous flight fcature of the auger. The depth of strata
' change is thus considered approximate. The soils encoun-
' tered in tlie borings wec•e �isually and manually classified
in accerdance with AST�1 D2487 Unified Soils Classification
+ System and ASTM D2488 "Recommended Practice for Visual and
' Mar.��al llescription of 5oils". A copy of A5TM D2487 is
, attachcd. Represent�tivc samples were then returned to our
� �aboratory for verificati�n of the fiold clsasifications by

� The borings were probod imaediately after their co�pietfon
to check for the preseace of groundwater. The borings were
; also rochecked prior to lcaving the site oa Fobruary 17.
Absence of groundwatar was noted in both probings of the
borings to their respactive 15-foot teraination depths. A
rechock of tlie boring 1 week later also encountered no •
groundwater to the 15-foot depth.
The percolation tests were run in 6-inch diameter boles
drilled to an approxi�ate depth of 36 inches, ia accosdaace
with procedures recomiaended by the �finnesota Department of
Health (MHD) and with the procedures recommended by the City
of Orono. In accordanca with these procedures, the bottoa�
and sides of the holes were scratched with a knife blade to
remove any smeared soil surfaces and to vrovide a natural
soil interface into which the water may percolate. ` Two •
inches of coarse sand was then placed in the bottoat of the
holes to prevent scouring. The holes were then carefully
filled with clear water to a minimum depth of 12 inches over •
tha top of the sand layer and allowed to soak overnight witb
the percolation tests being conducted the folloxiag day. An
insulation material was placed over the holes prior to
leaving the site to preveat freezing of the water sad soils
overnight.

You have indicated that 3-bedroom single faatily dwellings
are proposed for the lots.
� Based on the resuYts of the soii boriags and tha;�percolation
tests, it is our opinion that soil,; Water,;,,;tabls;,° and soil
absorptivity conditions encountered�ar�,�ttitab, for�installa-
tion of in3ividual sanitary systems i"th a d�a�„#ield as
the soil absorption unit for each of the lots. �
A minimwa of 200 square feet of abaorp�, '` eA `` eT�'badroo�
will be required on each lot, based on.th�e��asured rstes. For
� the proposed 3-bedroom homes, a minimus;,,of 600 square feet •
of absorptive area will be required. I�. is our opinion that
the underlying soils are in a stata somexhat drier than
normal and durin� periods of noraial conditions� percolation
rates may be somewhat higher. For this roason, we would �
� recommend a minimwn of 800 squara feet of absorptive area
for each lot. This requirement could be met by four 30-inch
wide trenches� 80 lineal feet in length each. Mith 7-foot
center to center spacing.

the water may percolate. . Two inches of crushed rock were
then placed in the bottom of the holes to prevent scouring.

on the percolation rates it appears that "`�he �spst�� should be
designed for 250 square feet of area per bedroo�. For a 4-
bedroom house. this could be met by 4 trenches 30:iaches vide
and 100 feet long, S trenchcs 80 feet long, 6 trenehes 67 feeL
lon�, os other combinations.
The area investigated by those percolation tests Miil not be
suitable for normal drainfield desi�n becguse. the results are <
of 6o mpi. Howovor, the area would be, suitabl� 'fos, ;'
