P.O. Box I40 Mack, CO 81525 970-250-0572 Sitc Ilistory There is an existing four-bedroom residence on the site that is served by an existing onsite wastewatertreatment system (owrs). The owners would like to bring the existing bwrs up ii c.r.."rrt code. Theexisting system will be abandoned and replaced with an owis designed to accommodate the four-bcdroomresidential loading. The site consists of approximately 3.29 acres of uncultivated native soil. Drainage is approximatety 3% tothe southeast' A soils evaluation and site study were conducted on the property"of r"f"i"n"" on 09/20124by Kachayla R' Cronko. The soils evaluation h'ench was located approximate ly 250, north of the sourthproperfy line and approximately 70, east of the west property line. This owTS design has been prepared for the project baserl on information disclosed during the site studymentioned above' A discussiol of the engine.t.a owrs design follows. The location of the soils evaluationtrench is shown orlthe plut plan included in this report. Develooment of Design parameters ,; The soils evaluation trench was extended to a depth of 96" below grorrrd surface (BGS). There fuas noevidence of ground water or periodically saturated soils in the open excavation to a depth of 96,, BGS. SoilType 3A was encountered near the surface of the evaluationirench; however, the proposed infiltrativesurface will be placed below the soils so it will not be considered a limiting tuy.r. 'rfr" soils evaluationindicates two distinct soil horizons underlie the site. A lithologicai descriptio=n fouows: description silty clay loam, brown (Soil Type 3,{, USDA - silty clay loam, granular, weak structure) silty loam, brown/white w/ minor gravel (<SX rock; (Soil Type 24, USDA - silty loam, massive, structureless) Based on the results from the 09120124 soils evaluation, Soil Type 2A and corresponding long termacceptance rate (LTAR) of 0.50 are chosen fbr overall system sizing-for an infiltrator trencfr soil treatmentarea designed to discharge to subsoils belorv the 4g" aepttr. depth (in.) 02'-24 24" -96" " Kachayla R' cronk holds a certificate of Attendance and Examination from the cpoW visual and TactileEvaluation of Soils Training. -1- Systern Design An INFILTRATOR ttench soil treatment system is proposed for discharge of septic effluent at the site. Construction of the system will consist of excavating level trenches in the soil treatment area. @!!ng durins construction mav affect slone. therefore contractor shall verifv slone at time of installation. Soil treatment area orientation may be adiusted Der site variations to facilitate consistent trench denth runnins narallel to final contours.Each trench excavation shall be continued to a level depth of 48" BGS at the uphill side of the trench (see Soil Treatment Area Cross Section). If consistent trench depth cannot be maintained, Iiy'F1ZZRlTOR chambers mav be installed level at 30" minimum and 48" maximum BGS. After removal of surface soils, the open excavations will be disked or scarified to promote subsurface absorption. Following completion of the trench excavations, QUICK4 STANDARD INFILTRATORS (or equivalent) will be used to construct a septic effluent distribution system in the open excavations. The INFILTRATOR effluent distribution system will be installed in accordance with the "Infiltrator Technical Manual", available from Infiltrator Systems Inc., 123 Elm Street, Suite 12, Old Saybrook, Connecticut 06475. Adiacent INFILTRATOR,S shall be fastened with a minimum of three G\3/4" self-tappins screws to prevent movement and separation during backfilling. Septic effluent will be transferred from the upper trench to each of the adjacent downhill trenches through a serial distribution network as shown in the included graphics. The serial distribution connections between adjacent trenches will facilitate the saturation of the uphill trench before septic effluent is allowed to flow to each of the adjacent downhill trenches. After the INFILTRATORS are installed, synthetic filter fabric (140-200 mesh) will be placed over the INFILTRATORS and the system will be covered with a soil cap. The soil cap will consist of approximately 36" of sandy loam backfill. The soil cap will be mounded 5%o above the existing ground surface to promote surface run off away from the soil treatment area. The installer should confirm the feasibility of gravity discharge of sewage effluent from the foundation line to the soil trcatment area by field verification of assumcd dcsign parametcrs. Assumed design parameters with respect to gravity discharge include: If the distance from the sewage pipe at exit frorn the foundation line to the entry of the soil treatment area is 50' or less, The elevation of the ground surface at the entry of the soil treatment area shall be no more than 27" above the invert elevation of the sewage pipe at exit from the foundation line. If field measurements do not confirm these design assumptions, gravity discharge of septic effluent from the proposed structure cannot be assured and a lift station may be required. Please contact the design engineer and Garfield Counfy to address any design modifications necessary if these design assumptions are not upheld. Thc existing tank must be rcmoved or abandoncd in placc. Abandonmcnt will consist of pumping the tank to remove as much waste as possible. The bottom, top, and sides must be crushed in to ensure the tank neither floats nor fills with water, and the remaining void must be filled with gravel, sand, ot compacted a a ., A l'250 gallon, twu cumpartment septic tank is required to provide a minimum of 4g hours retention timefor scwagc generated f.ro} thc nroqoscd project. Tire tank must be approved and accepted by cDpHE foruse as a septic tank' A list of such tanlis may be found here: https://cdphe.coloradi.govlowts un6s1"Regulation 43: product acceptance lists". Provide water-tight risers to ,urfu"" *ithl..ilely fitted lids foraccess to both compartmcnts of the septic tank. A non-corroJibl" o..rr"o filter (model# FTw0436-2g) shallbc installed at the final outlet tee of the septic tank to limit the size of solids and sludge passing into the soiltreatment area' The filter rnust be accessible for cleaning and replacement from thelround surface. As shown in the included graphics, the trench soil treatment system will consist of five (5) trenches 3,widex 48" deep a varying length with a total of sixty-two (62) INFILTRAT7R (or equirrateni) units. The soiltreatment area will encompass an effective area of 1,062.ti6 sq. ft.

The installer must be approved and licensed by Garfield County for installation of onsite wastewater treatment systems. All installation activities shall be conducted in accordance with current Garfield Countv OZIS Rggzlatiozs. If at anv time during construction. subsurface site conditions are encountered which differ from the desisn parameters previously described. construstion activities will stop. and the design engineer and Garfield Countv will be contacted to address anv necessarLdesign modifications. The final cover shall not be placed on sewer lines, septic tank, ot the soil treatment area untii the system has been inspected and approved by the design engineer and Garfield County. The installer shall provide 48-hour notice for all required inspections. Installation procedures including grade, location, setbacks, septic tank size, and soil treatment size shall conform with the attached graphic details. Construction activities and system components will not encroach upon existing easements or utility corridors. The installer must maintain all setbacks to utility lines, easements, property lines, or other adverse conditions, whether they are known and shown on the attached graphics or have been disclosed during construction. Vehicle traffic and parking is to be prevented over the soil treatment and repair area. Minimum setbacks for system components are: Septic Tank, Dosins Tank Building Sewer, Effluent Lines STA sorins/well/cistern 50 50 100 potable water supply line l0 5 25 structure w/ crawlspace 5 0 20 structure w/o crawlspace 5 0 10 property lines, piped or lined irrieation 10 10 10 subsurface drain, intermittent inigation t0 10 25 lake, water course, irrisation ditch, stream 50 50 50 cut slope steeper than 3H:1V 10 10 25 septic tank 5 . Four-inch,2-way clean out must be installed within 5' of the outside of the building. r All gravity flow sewer lines and effluent distribution piping shall be 4 inches in diameter and have glued joints. All lines discharging sewage liom the residence to the septic tank shall maintain a minimum fall of 1/8 in. per foot and shall employ sweeD 90's or 2-45's at all turns. All unperforated pipe used for gravity flow of effluent, including pipe from the foundation to the septic tank, and septic tank into chambers, must meet minimum standard ASTM-3034. Lines discharging from the septic tank to the soil trcatmcnt arca shall maintain a minimum fall of 1/8 in. per foot. Sewer lines under driveways shall meet the minimum Schedule 40 PVC standards. Additionally, effluent piping in traffic areas with less than 24" of cover shall be encased in 6" CMP or flow fill and covered with minimum 2" high densify blue board a a a a -4- Sewer lines or domesttc water lines shall be encased in minimum SCHD 40 with watertight end caps or a minimurn of 6" of flow filI at all points with less than 5' separation between sewer and domestic water lines. Four-inch, two-way clean outs shall be installed at maximum 100' intervals in all gravity flow effluent lines exceeding 100'in length. A minimum of 12" of soil cover (18" recommendcd) shall be maintained over all gravity draining OWTS components to prevent freezing of septic effluent (excepting septic tank access ports which must be extended to the ground surface). The system contractor shall be aware of the potential for construction activities to reduce soilpermeabilities at the site through compaction, smearing, and shearing. The following precautions and construction procedures should be employed during instaJlation to minimize disturbance to native soils: i. Excavation should proceed only when the moisture content of the soil is below the I plastic limit. If a eample of soil forms a ropc instead of clumbliug when rolled between the hands it is too wet and should be allowed to dry befoie excavation continues. ii. Excavation and backfill equipment should work r&om the surface where at all practical to avoid compaction of the soils at depth. {iii. The bottom and sidewalls of the excavation should be left with a rough, open surface. The appearance should be that ofbroken or ripped soil as opposed to a sheared, smeared, or troweled surface. Any smoothed or smeared surfaces should be removed with a tuuthed rake or shallow ripper, taking care to remove loose residues from the bottom of the excavation by hand if necessary.iv. Care should be taken in placing fill materials in the excavation tp avoid damaging the exposed soil surfaces. Operation - Maintenance and Inspections o The owner shall install a structural barrier if necessary and take precautions to prevent vehicular traffic, excessive surface watering, accidental flooding, or other activities in the vicinity of the soil treatment area which may compact, saturate, or otherwise alter the subsurface soil parameters used in designing the septic system.o The owner will plant and maintain grass or other shallow rooted cover crop to prevent erosion . and promote evapotranspiration over the soil treatment area.o The owner will inspect and maintain the required mounding and drainage away from the soil treatment area to prevent saturation from precipitation and surface flows.o To mitigate the generation of preferential flow channels which may compromise the operation of the system, the owner will inspect and prevent intrusion of burrowing animals and deep- rooted plants into the soil treatment area.. The septic effluent filter shall be inspected and cleaned as necessary every six (6) months.o The ownet will conduct periotlic maintenance of the septic system by removing accumulated sludge from the septic tank every 3-4 years to prevent clogging of the soil treatment area. a a o a -5- Limitations This report is a site-specific design for installation of an onsite wastewater featment system and is applicable only for the client for whom our work was performed.

C{l g7&s ia, a fr z 1 &*x &aylra tr**&r8ro.urfft lt{,f srp NOTES FOR YOUR INSTALLER This is a STAMPED. ENGINEERED design - yos, septics are "simple" and water runs downhill. However, like anything that is engineered, it is critical that you follow the design so the system performs as intenped - I cannot approve a system that was not installed to plans! If, FOR ANY REASON, you need to: 1. Change the location/rotation of the septic tank (i.e. ptiu-Uing was stubbedput of different wall, etc.) 2. Change the location/rotation of the soil treatment area (i.e. slope differed from the design, owner has changed the site plan, etc.) YOU MUST CONTACT THIS OFFICE F'OR A REYISED DESIGN! The revision must be submitted and approved through the Counfy (with a County $ revision fee) prior to calling in for inspection. Revisions take time, so please be prompt when contacting us to ensure the project is not delayed. '' Next, and I cannot stress this enough - DO NOT install the charnbers DEEPER than the maximum depth stated in the design - the depth is determined by factors that the design engineer cannot CONtTOI. This includes SATURATED/POOR SOIL CONDITIONS & COUNTY owTs CODE. Our designs give the widest range of depth possible for the specific site - if the required depth cannot be met, other options may need to be explored. If the soil treatment area is installed at a depth greater than allowed, there are very few solutions to resolve the problem. Examples include: o Removing all components and reinstalling them in a different location at correct depth.o Backfilling trenches to an acceptable depth (using WASHED CONCRETE SAND ONLY), installing a pump chamber, effluent pump, and pressurizing the system. Please reach out at any time during the installation process if you have any questions - this office has experienced several installations that have failed County inspections due to issues described above - I would like to see every system PASS without comment as this makes everyone's job easier.
