ANY INCREASE IN NUMBER <br /> 2965 Deer Run T'rail OF BEDROOMS INVALIDATES THIS DESIG(�. <br /> Orono, Nennepin County. ORO�?G COPY <br /> To whom it may concem, <br /> I was contacted by Michael&Carol Swenson to inspect a failing mound system and design the <br /> repair for the system at 2965 Deer Run Trail.In the city of Orono.The results of the inspection and <br /> design are as follows. <br /> Water was surfacing out of the top of the rock bed. [drilled borings around the rock bed.The <br /> soils below the rock were dry.This indicates d�at tlie rock bed is plugged."fherefore the solution is to <br /> remove the existing rock bed and any of the sand material under the rock that is not clean.Then replace it <br /> �vith clean materials.The existin�tanks should be checked that they are still water tight. <br /> The tces of the existing system exceed the minimum design criteria.There is one rock bed <br /> approximately 68 feet in length.This w�ll take approximately 28 cubic yards of roek.The sandy loam cap <br /> will require approsimately 2l cubic yards.The topsoil required will be approximately 19 cubic yards.The <br /> clean sand required will be approximately 28 cubic yards.This number may vary greatly due to the faet <br /> that. We don't know ho�v plugged the sand is until the rock bed is removed.The laierals will require 198 <br /> iineal feet of 2inch pipe with a 7/32 inch perforation every 36 inches. <br /> The original grade under the rock bed is at elevation 98_9 the bottom of the new rock bed must be <br /> at elevation 100.7 the garage concrete slab was used as a T.B.M.Elevation 100_00 assumed. <br /> Clean outs must be installed on the end of the laterals for maintenance. If there is an iron filter in <br /> the house it must be�lumbed out of the septic s s�tem <br /> Nott�ina other than Era�water,(laundrv.showe�sr etc.) Human water and toiiet tissue <br /> should be disposed of into the seutic tanks. Garbage disuosals are not recommended. Additives <br /> must not be used•thev mav cause harmful dama�e to vour sentic svstem. It is recommended that <br /> rou aump the taaks everr two vears. <br /> If you have any questions piease call. <br /> ORONO COPY Sincerely, <br /> CITY OF ORONO <br /> SEPTIC PER�1�1 IT P AI�f� Joseph J.Ulson <br /> �NSPECTOR /l ,.����L���W� , ,, <br /> DAT - - � PERMIT NO.,,_,,,,,,,,� <br /> � API'ROVEQ AS SCBMITTED <br /> APPRUVED W[TH CORRECT(ON$AS NOTEp <br /> NOT APPRnVE0.CORRECT Q�RESUA`fIT <br /> '�'f+ose�mmenta are tm your information.
