The property is located outside of Glenwood Springs, in an area where OWTSs and wells are necessary. SITE CONDITIONS A 2-bedroom, single-family residence presently exists and is utilizing an existing OWTS which includes a single-compartment concrete septic tank with a pipe and gravel soil treatment area (STA) of unknown size. The OWTS was experiencing back-ups into the house and the tank has been pumped several times. The west end of the existing STA was excavated and the gravel was found to be clean and dry. This leads us to believe there is either excessive clogging at the front (east) end of the existing STA, a broken pipe, or an unlevel manifold. The decision was made to pursue a new system design rather than attempt to repair the existing OWTS. The private water well on the property is located greater than 100-feet from the proposed STA and greater than 50-feet from the proposed septic tank. The proposed soil treatment area is a flat, filled yard area to the north of the northwest of the existing residence. The existing STA will need to be removed in order to accommodate the new STA. The remainder of the property, both to the north and south, slopes steeply to the south toward Hwy 82 and the Roaring Fork River. SUBSURFACE The materials encountered in the Test Pit #1 consisted of topsoil to 6.0-inches, underlain by reddish brown loamy sand to 1-foot, underlain by gray to tan silty loam to 2-feet (imported fill), underlain by the existing STA consisting of pipe and gravel, underlain by reddish brown loamy sand with 12 to 18 -inch diameter cobbles. No bedrock or groundwater was encountered. The native materials encountered in Test Pit #2 were consistent with those encountered in Test Pit #1. None of the existing STA or imported fill was encountered during the excavation of Test Pit #2. Cobbles below 3-feet in Test Pit #2 were fewer and smaller in diameter. The Test Pit was explored to a maximum depth of 7-feet. No bedrock or groundwater was encountered. A tactile analysis of the soils was taken from Test Pit #1 at 3-feet below grade in an area outside the existing STA. The soil formed a ball, but did not form a ribbon. Soil structure shape was granular, soil structure grade was moderate, and consistence was friable. Page 2 STA sizing is based on Soil Type 1, Loamy Sand with granular structure type and moderate structure grade. A long term acceptance rate (LTAR) of 0.8 gallons per square foot will be used to design the OWTS, in accordance with Table 10-1 Soil Type 1 presented in the Garfield County On-Site Wastewater Treatment System Regulations, adopted April 14, 2014. Test Pit #1 Profile Sieved soil Profile encountered existing STA Note pipe and gravel Page 3 Test Pit #2 Profile Bottom of pit Top of pit DESIGN SPECIFICATIONS The existing single-compartment concrete septic tank will be either abandoned in place or removed. The existing STA will be removed in the area of the new STA. The gray to tan silty loam imported material covering the existing STA must be completely removed. The new OWTS design is based on 3-bedrooms. An average daily wastewater flow of 450 GPD will be used. Design Calculations: Average Design Flow = 75 x 2 x 3 Bedrooms = 450 GPD LTAR = 0.8 GPD/SF 563 GPD / 0.8 GPD/SF x 1.0 (pressure dosed bed) x 0.7 (chambers) = 393.75 SF Page 4 The system installation will include a new 1000-gallon, three-compartment concrete septic tank with an Orenco® Biotube Pump Vault and PF3005 pump in the third compartment. The control panel for the pump must be located within line of sight of the septic tank. Effluent will be pressure dosed through a 1.25-inch diameter pump line to a new STA. The pump line must slope a minimum of 1% to either drain back into the septic tank or drain completely to the STA, depending on grades. The new STA will be over excavated and approximately 1-foot of ASTM 33 concrete sand should be placed as a level base under four rows of 8 ‘Quick 4’ Infiltrator® chambers, connected with a level manifold. Zip ties will be used to hang 1.25-inch diameter laterals to the underside of the chambers. The 1.25-inch diameter laterals will have 1/8-inch diameter orifice holes facing up (with the first and last holes facing down for drainage), 2-feet on center. Each lateral must end in a 90 degree elbow facing up with a ball valve for flushing in a valve box, accessible from grade. These may be cut to grade and covered with a valve box for access. The component manufacturers are typical of applications used by contractors and engineers in this area. Alternatives may be considered or recommended by contacting our office. Construction must be according to Garfield County On-Site Wastewater Treatment System Regulations, the OWTS Permit provided by Garfield County Building Department, and this design. REVEGETATION REQUIREMENTS An adequate layer of good quality topsoil capable of supporting revegetation shall be placed over the entire disturbed are of the OWTS installation. A mixture of native grass seed that has good soil stabilizing characteristics (but without taproots), provides a maximum transpiration rate, and competes well with successional species. No trees or shrubs, or any vegetation requiring regular irritation shall be plated over the STA. Until vegetation is reestablished, erosion and sediment control measures shall be implemented and maintained on site. The owner of the OWTS shall be responsible for maintaining proper vegetation cover. OPERATION INFORMATION AND MAINTENANCE The property owner shall be responsible for the operation and maintenance of each OWTS servicing the property. The property owner is responsible for maintaining service contracts for manufactured units, alternating STAs, and any other components needing maintenance. Geo-fabrics or plastics should not be used over the absorption area. No heavy equipment, machinery, or materials should be placed on backfilled STAs. Livestock should not graze on the STA. Plumbing fixtures should be checked to ensure that no additional water is being discharged to OWTS. For example, a running toilet or leaky faucet can discharge hundreds of gallons of water a day and harm a STA. The homeowner should pump the septic tank every two years, or as needed gauged by measurement of solids in the tank. Garbage disposal use should be minimized, and non-biodegradable materials should not be placed into the OWTS. Grease should not be placed in household drains. Loading from a water softener should not be discharged into the OWTS. No hazardous wastes should be directed into the OWTS. Mechanical room drains should not discharge into the OWTS. The OWTS is engineered for domestic waste only. ADDITIONAL CONSTRUCTION NOTES If design includes a pump, air release valves and weep holes must be installed to allow pump lines to drain to minimize risk of freezing. The pump shall have an audible and visual alarm notification in the event of excessively high water conditions and shall be connected to a control breaker separate from the Page 5 high water alarm breaker and from any other control system circuits. The pump system shall have a switch so the pump can be manually operated. Excavation equipment must not drive in excavation of the STA due to the potential to compact soil. Extensions should be placed on all septic tank components to allow access to them from existing grade. Backfill over the STA must be uniform and granular with no material greater than minus 3-inch. INSTALLATION OBSERVATIONS ALL SERVICE septic, LLC must view the OWTS during construction. The OWTS observation should be performed before backfill, after placement of OWTS components. Septic tanks, distribution devices, pumps, dosing siphons, and other plumbing, as applicable, must also be observed. ALL SERVICE septic, LLC should be notified 48 hours in advance to observe the installation. LIMITS: The design is based on information submitted. If soil conditions encountered are different from conditions described in report, ALL SERVICE septic, LLC should be notified. All OWTS construction must be according to the county regulations. Requirements not specified in this report must follow applicable county regulations. The contractor should have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. Licensing of Systems Contractors may be required by county regulation. Please call with questions.

Pump curves show the relationship between flow (gpm or L/sec) and pressure (total dynamic head, or TDH), providing a graphical representation of a pump’s optimal performance range. Pumps perform best at their nominal flow rate — the value, measured in gpm (or L/sec), expressed by the first two numerals in an Orenco pump nomenclature. At low flow rates, TDH varies from pump to pump, so it is represented as a dashed line in the pump curves. For most accurate pump specification, use Orenco’s PumpSelect™ software. 60 Hz Models T o t a l d y n a m i c h e a d ( T D H ) i n f e e t Gallons per minute (GPM) PF10 Series, 60 Hz 1/2 hp to 2 hp PF1005 PF1010 PF1005-FC w/ 1/4" fl ow controller 5 100 15 20 25 3000 300 250 200 150 100 50 0 350 T o t a l d y n a m i c h e a d ( T D H ) i n f e e t Gallons per minute (GPM) PF20 Series, 60 Hz 1/2 hp to 1-1/2 hp PF2005 750 900 600 450 300 150 0 5 10 15 20 25 30 35 400 T o t a l d y n a m i c h e a d ( T D H ) i n f e e t Gallons per minute (GPM) PF30 Series, 60 Hz 1/2 hp to 5 hp PF3030 PF3005 250 300 200 150 100 50 0 10 20 30 40 50 60 700 400 350 450 T o t a l d y n a m i c h e a d ( T D H ) i n f e e t Gallons per minute (GPM) PF50 Series, 60 Hz 1/2 hp to 5 hp PF5030 PF5007 PF Series High-Head Effluent Pumps (continued) PF2010 PF2015 PF1007 PF3020 PF3007 PF3010 PF3015 PF5015 PF5005 PF1020 PF3050 PF5010 PF5050 © 2008 Orenco Systems® Inc.NTD-PU-PF-1 Rev. 1.6, © 7/08 Page 4 of 6 PF Series High-Head Effluent Pumps (continued) 60 Hz Models (continued) PF Series High-Head Effluent Pumps (continued) 100 90 80 70 60 50 10 20 30 40 50 60 700 80 90 1000 40 10 20 30 T o t a l d y n a m i c h e a d ( T D H ) i n f e e t Gallons per minute (GPM) PF75 Series, 60 Hz 1-1/2 hpPF7515 © 2008 Orenco Systems® Inc.NTD-PU-PF-1 Rev. 1.6, © 7/08 Page 5 of 6 10 20 30 40 50 600 0 3.01.0 2.0 4.0 40 35 30 25 20 15 10 5 0 45 160 140 120 100 80 60 40 20 0 T o t a l d y n a m i c h e a d ( T D H ) i n f e e t Gallons per minute (GPM) PF50 series, 50 Hz 0.37–1.11 kW PF500752 PF500552 PF501052 T o t a l d y n a m i c h e a d ( T D H ) i n m e t e r s Liters per second (L/sec) 105 20 25 300 350 300 250 200 150 100 50 0 15 0.2 0.80 1.4 1.80.4 0.6 1.21.0 1.6 100 80 60 40 20 0 T o t a l d y n a m i c h e a d ( T D H ) i n f e e t Gallons per minute (GPM) PF30, 50 Hz 0.37-1.11 kW PF300552 Liters per second (L/sec) T o t a l d y n a m i c h e a d ( T D H ) i n m e t e r s 3 60 9 12 250 200 150 100 50 0 80 70 60 50 40 30 20 10 0 90 0.1 0.40 0.70.2 0.3 0.60.5 T o t a l d y n a m i c h e a d ( T D H ) i n f e e t Gallons per minute (GPM) PF10, 50 Hz 0.37–0.56 kW PF100552 PF100552-FC w/ 6-mm fl ow controller PF100752 Liters per second (L/sec) T o t a l d y n a m i c h e a d ( T D H ) i n m e t e r s PF Series High-Head Effluent Pumps (continued) 50 Hz Models PF Series High-Head Effluent Pumps (continued) PF300752 PF301052 PF301552 PF501552 © 2008 Orenco Systems® Inc.NTD-PU-PF-1 Rev. 1.6, © 7/08 Page 6 of 6 feet meters 500 100
