Sketch Plan - Septic Concerns
I have transferred the soil survey information to a copy of
the proposed plat, and would make the following preliminary
comments for sketch plan review:
1. Soils on the west half of the site are mainly LeSueur
loam, slopes genera lly 6$ or less and water table generally
no higher than 3' be low the surface. The lots designated as
Lots l , 2 and 3 , B1ock ,Y?�and Lots 1 and 2 of Block�2',� have
substantial areas of LeSueur loam and probably will find
suitable sites for mound _.��stems,.._ .. ,.. . ._. ....�... _. �. ,.. ...._ ,.._.__._,�.,.,._�,_...�,
__ , ..:,.. .. _�.._.... _..__.._r ' �
�� 2 Lots 3 and 4 , Block ,2� contain areas of Kilkenny and ;
Lester clay loam soils which generally are a little heavier �
clay soils. Again, these lots would probably require mound '
,'� systems and both appear to have some area of acceptable�
' �,s lopes . ....,.:. . _.. ._.. _ ,_

3 ^The existing farmstead in Lot 5 , Block �2' ( 2225 Sixth
Avenue North) has one 1, 000 gallon pre-cast concrete tank
west of the farm house, and drainfield that is unknown.
Notwithstanding concerns about drainage through the west end
of this lot, there may be suitable expansion sites west of
the house. The higher ground on which most of the buildings
;are located is a Hayden clay loam, often requiring mound
systems due to slow perc rate, with the areas west of the
house appearing to be a Glencoe silty clay loam which often
precludes the use of a� system.
I
4. Lots 6, 7, 8 and 9 of Block� contain substantial a�eas
of Glencoe soil which often has water table at the surface
during the wet season. Lots 6 and 7 would appear to have a
drainageway from the north bisecting these lots into a front
and rear portion. Lot 6 may have some mound sites on the
fringes of the Glencoe at the front or rear of the lot. Lot
7 will have an extremely difficult time trying to find
drainfield sites that are more than 75' from the designated
wet land area. Lots 8 and 9 are a 1 so quite low, containing
most ly wet soils. These two lots might find suitable mound
sites near the road, probably ending up in front yard areas.
Both Lots 8 and 9 have a number of drainage concerns, as
they are the receiving area for overland flows from the
west.
' ' Zoning File #1519 - Septic Concerns
March 30 , 1990
Page 2 of 2 n� Uo� �
5. Lot l0�has a little bit of everything, including flat,
wet soi ls, steep s lope soi ls, and high ground to the west.
It may be possible to find sites either just above or just
below the steep sloped Lester clay loam area.
Summary -
The proposed lots in the west half and northern tier of this
proposal probably will have suitable drainfield sites. Lots 6
through 9 are very questionable due to mostly wet soils and
drainageways.
I have compiled the available soils information, topography,
and wetlands map into an overlay drawing for your review. In
proposed Lot 7, the designated wetlands appear to be more
extensive than shown by the surveyor. The same holds true for
Lot 10.
On paper Lots 7, 8 and 9 look pretty questionable. Perhaps
a site inspection will he lp to confirm whether these concerns are
valid.

City Ordinance 199 requires that each existing on-site sewage treatment system in Orono be inspected every two years.
The on-site sewage treatment system at the above address has been inspected and appears to fall into the categories checked below.
S STEM CONFORMITY 1-3 : �
] "CODE SYSTEM" An ISTS which meets all the location,design and construction standards ofthe current Orono Municipal Code.
2 "COMPLIANT SYSTEM" An ISTS which does not meet all the location,design and construction standards of the current Orono
Municipal Code but does meet the three foot separation requirement or two foot requirement for systems installed 1996 or earlier,and
which is not failing or an imminent threat to public health or safety.
3 "NON-CONIPLIANT SYSTEM" A prohibited ISTS;an ISTS located within a designated 100-year flood plain,any ISTS which may
or may not meet all the location,design,or construction standards of the current Orono Municipal Code and which is failing for any
reason;and any ISTS with less than three feet of unsaturated soil or sand between the distribution device and the limiting soil chazacteristics.
TANK CONDITION(5-7): �
Tanl:inspection indicates:
5� Pumpout not needed at this time.
6 Septic tanks must be pumped out this year (city code recommends tanks to be pumped out once every 3 years.
Tank was last pumped i c-�- c 3 ).
Make sure septic tanks are pumped through manhole and not throu�h white inspection pipes. This allows for the proper
cleaning. Keep water softner and iron filter discharee out of septic svstem to prolonQ life of drainfield. Ask pumper to test
alarm float to verify alarm is still working in your house. The alarm warns owner that septa�e is about to backup into basement.
7 Inspection risers missing-tanks could not be inspected. Inspection risers(4" dia.pipe)must be installed in each tank. If
tanks have not been pumped out within the last three years,they should be pumped out now.
DRAINFIELD CONDITION 8-10 : �
8 Drainfield is dry,no surfacing evident.
9 Some evidence of surfacing,not critical yet.
10 Drainfield is saturated and visibly discharging untreated effluent to the surface. Contact the City Inspector
immediately.Repairs must be completed within 90 days.

Septic Tank(s) Pump out Needed
Yes �No
The City recommends the septic tanl:(s) and/or lift tanlc be serviced and pumped
out every three years. City records indicate the tank(s) were last pumped out on
[� -1 ._c,3 . The tank(s) should be cleaned through the manhole and

SYSTEM COMPLIANCE (1-3) : 1
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 is � ] or is not [ ] identifiad under this septic system. If tha
saturatad soil lavel is not id�entified, this classification is subjact to ravision.)
K CONDI'I'ION (5-9) : 5
5 Pumpout not needed at this time.
6 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.
10 One or more tanks are cesspools, which means the septic system is non-compliant.
(Tha tanks ara [� or ara not [ � water tiQht or the condition is [ ] unknown. If the tanks
are not confirmad to be watartiQht, this classification is subjact to ravision.)

The following information concerns the design of a pressure mound
system .for a proposed 4 bedroom house on the above described prop- •
erty. All construction and materials must conform to the standards
of the City of Orono and MPCA Chapter 7080 .
All construction traffic must be kept off both the primary and alt-
ernate drainfield areas . These areas should be marked off prior
to construction.
A pumping tank will be needed to house the pump which is necessary
for pressure distribution to the system.' The supply lines must be
constructed to dr.ain back to the pumping tank. .A weather proof eri-
cl.osure will also be needed, to house the controls and switches.. for
the pump. Also, a warning light/sound system will be needed to
warn of pump failure .
If any other information is needed, please contact us .
