upgrading of the system is required at this time.

adequately at this time, but has a relatively high potential for future problems. No major upgrading of system is required at

creating a safety hazard, or is otherwise creating a public nuisance.Please contact the City Inspector to discuss system repair/
replacement procedures. If drainfield replacement is necessary,soil testing will usually be required,and a design and site plan
must be submitted for review.Your contractor must obtain a permit before work is started.

A site ev�luation was completed qn these� properties for the existing on-site sewage
treatment systems suppor#ing the existing cabins. The existing systems are classified
as failing due to not meeting ti�e 3' separation from the saturated soil (mottled soil) or
iack of syst�m. The existing tanks are old, either metal or block type and will need to be
abandoned, pumped and filled with soil. A new system wi{I need to be installed.
This an-site sewage Veatmer�t Cluster �ystem is designed for a Type 3, 3 bedroom 218
gal/day each cabin tataling 654 gal/day, in accordanGe, with the Minnesota Poliution
Contral Agency Chapter 7080 an� local ordinances. An easement agreement will be
required by the c�ty. The �greement will require a maintenance schedule for m�intaitting
the tariks, and sh��ed electrical Costs, etc. A water meter wili need to be installed in
e��h cabin #a monitor tf�e d�ily w�ter use and to be recorded with the property. The
system wiEl be �' irom the property line and up to the road easemer�t, this will need
�pproval from the City. A�pr'oval will also b� nseded for � tank ta be 5' from the Robb
cabin to stay out of a tow afea.
The soiis on this site are SCS soils map�ed - HbC - Hayden loam. The se�sanally
saturated sails were located at 5'10". The bottom of the treatment area must be located
at least 3' above the seasona{ly saturafed soils. A standard gravelless 10" diameter
trench system may be installed.
The soils �t a depth of 30" have a percalation rate averaging 10.4 mpi_
1
ii�%1�%�Ji, 11:15 FA1 1i12�975011 S P TESTI�c, I�i; f�ji.i3
Due to the system being sized for 1.27sq.ft. (perc rate 9 0.4) low water use facilities will
nEed tq be instelled in all three properties. If water softners are used, they mus# be
diverted either to the �round surtace (not the lake) or install approximately 50 lin.ft. of
g�ave�less trench.
The new tanks may be plastic �ut must be heavy duty due to the high water tabie, see
the site plan for the focation.
A pumping chamber will need to be installeGi to lif[t�e septic effluent to the treatment
area. The power supply �nd switChes must be located outside fhe manhple �nd
pumping ch�mber in a weather proof enclosure. A waming device must be instalfed with
a iight and s�und dBviCe, thi� is in c�se of a pump failure. An exterior devi�e wi11 need
to be instslled.
AH neighboring we{Is are located greater than 100' away from the proposed treatment
area and 50' away on this site (de�p well). Approval wi{I be needed to be 50` away from
a well with a t�nk at t[�e Rabb cabin.
Keep all he�vy gquipment off of the proposed treatment area before and after
Cor�struction. The treatment �rea should kye marked off befor� construction. This
Design is not valid & the system wi11 need to be relocated if failure to prpt�ct the areas
prapased for �n-Srte Sewage Treatment accurs_
With proper installation and maintenance, this system should have no prohlem in
treating septic efFluent e�fec#ively.
Nothing other than gray water �laundry, showers, etc,} should be disposed of into the
septi� tanks. Garbage disposals are not recommended, due to adding more solids 8�
fine solids passing through to the system. Excessive amounts of soaps, cleanin� agents
& chlonne agents m�y kill the bacteri� needed to treat septic effiuent. Additives are not
recommended. Recommend to pump & clean yoUr tanks through the manhole by a
certifed pumper every 2 years. �hec�c with your pumper to set up a schedule.
