Septic Check, Inc. | 6074 Keystone Rd Milaca, MN 56353 | ph. 888-983-2447 | fax. 320-983-2151 1  <br />  <br />  <br />Property <br />Owner: Ellen Forcier – 4780 N Arm Drive Orono, MN 55364 <br />  <br />Proposed Update Summary: <br /> <br />This is a Type IV septic system design for an existing lot that has part of the old house foundation still in <br />the ground. Originally the City of Orono requested the owner have a septic professional prove that the <br />site could meet City’s septic ordinance which requires (2) - Type I septic system sites with a 5-bedroom <br />capacity of 750 gallons per day. Although we found 25” of usable soil, which is a characteristic of a Type I <br />system, a vast majority of the site is either compacted or has disturbed soils. In lieu of the city ordinance, <br />we proposed a Type IV pretreatment system as it would provide an effective long-term solution for the <br />site that would not require the need for a secondary site. <br /> <br />The owner plans to rebuild a new 3-bedroom Class I home. The new home will not have a garbage <br />disposal or a sewage ejector. Sewage will flow by gravity from the home into a Brown Wilbert 2,250 <br />gallon 3-compartment tank. The first 757-gallon compartment will be used for septic, the second <br />compartment consisting of 757 gallons will be for septic as well as equipped with an EcoPod E50 <br />pretreatment unit. From there effluent will flow by gravity to the last compartment containing 757 gallons <br />that will be used for the pump tank. The pump installed must deliver at least 29.0 GPM and 18.1 TDH. All <br />manholes will need to be installed to grade for ease of servicing. Effluent will then be time dosed to a 10’ <br />by 38’ rockbed mound with no less than 1’ of washed sand at the NE rockbed corner. The SE, SW and <br />NW corners will require more than 1’ of washed sand in order to reach the bottom of the rockbed <br />elevation which 97.60. From there the installer will add 12” of washed 1 ½” rock, laterals, cleanouts and <br />inspection pipes to grade. 18” of cover will be placed next with a minimum of 6” of topsoil to establish <br />vegetative cover. <br /> <br />The table below is found on page 12 of the EcoPod Installation, Operation and Maintenance Manual. I <br />have included the manual in the design pages. It shows tank sizing requirements needed for the EcoPod. <br /> <br />System detail: <br /> Brown Wilbert 2,250-gallon triple compartment tank <br /> 1st compartment 757 gallons for sewage <br /> 2nd compartment 757 gallons for sewage equipped with an EcoPod E50 <br /> 3rd compartment 757 gallons to serve as the pump tank <br /> (5) 24” insulated manhole covers to grade. <br /> Ultra-rib riser attached with ADH 100 - or two-part epoxy <br /> Insulate top of tank if buried less than 2’ <br /> Goulds PE 41 effluent pump <br /> CP2210/MN Control Panel; included with EcoPod unit - See attached specs <br />Septic System Design <br />Additional Information
