The property is located outside of Glenwood Springs, in an area where OWTSs are necessary. Due to a change in the site plan and regulatory requirements pertaining to soils, previous design documents dated September 26, 2016 and May 20, 2020 should be discarded and replaced with these dated July 1, 2020. Legal Description: Section: 5 Township: 7 Range: 88 Subdivision: LOS AMIGOS RANCH SUB-DIV#2 FLG2 Lot 12 Parcel ID: 2393-053-05-011 SITE CONDITIONS The property is currently undeveloped. A 4-bedroom, single-family residence is proposed. The residence will be served by a community water system. No OWTS components will come within 25- feet of the water line. The proposed STA location has an approximate 15-20% slope across the proposed STA. The STA location is vegetated with pinyon pines and cactus. There are no potential future land use changes or bedroom additions planned for the property. SUBSURFACE The subsurface was investigated on September 13, 2016 by digging two soil profile test pit excavations (Test Pits). A mini -excavator was used to excavate the test pits. Visual and tactile soil analysis was completed by Carla Ostberg at the time of excavation.' The materials encountered in the Test Pit #1 consisted of medium brown silt loam topsoil to 2.0-feet, underlain by light tan, very dense, hard, calcareous clay matrix to a maximum depth explored of 4-feet. Digging was difficult with a small machine. No bedrock or groundwater was encountered. The materials encountered in the Test Pit #2 consisted of medium brown silt loam topsoil to 2.0-feet, ' Carla Ostberg holds a Certificate of Attendance and Examination from the CPOW Visual and Tactile Evaluation of Soils Training. Page 2 underlain by light tan, very dense, hard, calcareous clay matrix to a maximum depth explored of 4-feet. Digging was difficult with a small machine. No bedrock or groundwater was encountered. A tactile analysis of the soil was taken from Test Pit #1 at 1-foot below grade. The soil formed a ball and a very weak ribbon, less than 1-inch before breaking. Soil structure shape was blocky, soil structure grade was loose, and consistence was loose to friable. The texture of the soil was smooth. A tactile analysis of the soil was taken from Test Pit #1 at 3-feet below grade. The soil formed a ball and ribbon, less than 1-inch before breaking. The calcareous clay matrix, once broken up, becomes very fine-grained and powdery. STA sizing is based conservatively on Soil Type R-0. A minimum of 3-feet of "Secondary Sand" will be place in over -excavated beds. A long term acceptance rate (LTAR) of 0.8 gallons per square foot will be used to design the OWTS. Test Pit #1 Test Pit #1 Sieved sample of topsoil Topsoil over calcareous clay matrix Sieved sample of calcareous clay matrix Page 3 Test Pit #2 Maximum depth explored 4.0-feet If desired, an additional test pit may be excavated to properly evaluate soils under current code requirements. If at least 4-feet of suitable soils are observed, the previous design dated May 20, 2020 may be utilized. This office and Garfield County Environmental Health Department must be contacted to observe the soils. DESIGN SPECIFICATIONS Design Calculations: Average Design Flow = 75GPD x 2 people/bedroom x 3 bedrooms + 75 GPD (4th bedroom) = 525 GPD LTAR = 0.8 GPD/SF 525 GPD / 0.8 GPD/SF = 656.25 SF The OWTS design is based on 4-bedrooms. An average daily wastewater flow of 525 GPD will be used. For the purposes of this OWTS design, Benchmark Elevation has been established as 100' as the sewer line exiting the residence. ALL SERVICE septic should be notified of any discrepancies or problems with grade elevations of proposed components during installation of the OWTS. OWTS Component Minimum Elevation Primary Tank Inlet Invert Approx. 15' horizontal distance / 2% grade to tank / min. 4" drop. Automatic Distributing Valve Approx. 30' horizontal distance / 1% for drain back / min. 4" rise. Infiltrative Surface Approx. 7' horizontal distance to upper bed / 1 grade to bed / min. 1" drop. The system installation will include a 1500-gallon, two -compartment concrete septic tank with an Orenco® Pro Pak and PF3005 pump in the second compartment of the septic tank. Floats must be set to dose approximately 70 gallons per pump cycle. The pump must be capable of 23.1 gallons per minute (GPM) and 20.6 total dynamic head (TDH). The control panel for the pumping system must be located within line of sight of the septic tank. We recommend Valley Precast out of Buena Vista be contracted to perform pump start-up on the system. Page 4 Effluent will be pressure dosed through a 1.5-inch diameter pump line to a Model 6402A Automatic Distributing Valve (ADV) which must be located at the high point and accessible from grade. The 1.5-inch diameter pump line must have a minimum 1% grade for proper drain back into the septic tank after each pump cycle. The ADV will have two 1.5-inch diameter transport lines to two separate gravelless chamber beds. Effluent will be pressure dosed through a 1.5-inch diameter pump lines to two 6.5' x 51' beds. A minimum of 3-feet of sand filter material will be installed in the over -excavated footprint. There must be at least 6-feet of undisturbed soil between each bed. Sand filter material must be clean, coarse sand, all passing a screen having four meshes to the inch. The sand must have an effective size between 0.15 and 0.60 mm. The uniformity coefficient must be 7.0 or less. Material meeting ASTM 33, for concrete sand, with three percent or less fines passing 200 mesh sieve may be used. A gradation of the sand media must be submitted to this office prior to obtaining the sand. Laterals must be 1.5-inches in diameter with 5/32-inch diameter orifices facing down, spaced 3-feet on center, installed on the GeoMatTM with the filter fabric over the laterals. Laterals should be placed 2-feet from the edges of the bed, with 2.5-feet between the laterals. Note that the GeoMatTM is 39-inches wide, so two GeoMatsTM must be placed on the 6.5-foot wide bed. All material associated with the GeoMatTM installation must be proprietary products associated with the GeoMatTM, including orifice shields and geotextile fabric. Manufacturer instructions must be followed regarding installation of the GeoMatTM Each 1.5-inch diameter lateral must end in a sweeping ell facing up with a ball valve for flushing. Laterals must be covered by a soil separation fabric and at least 1-foot of topsoil or other suitable soil able to support vegetative growth. There shall be no cobble -sized (<2.5") or greater rock in final cover over the GeoMatTM Inspection ports must be placed at each corner of each bed. Ports may be cut to grade and covered with a valve box for access. Please contact us prior to ordering GeoMatTM for instructions. This design requires a minimum of 200' of 39" GeoMatTM and 60 orifice shields. 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 area 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 placed 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 Page 5 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. If an effluent filter or screen has been installed in the OWTS, we recommend this filter or screen be cleaned annually, or as needed. If the OWTS consists of a pressurized pump system, we recommend the laterals be flushed annually, or as needed. 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, 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 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.

Using a Pump Curve A pump curve helps you determine the best pump for your system. 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, expressed by the first two numerals in an Orenco pump nomenclature. The graphs in this section show optimal pump operation ranges with a solid line. Flow flow rates outside of these ranges are shown with a dashed line. For the most accurate pump specification, use Orenco's PumpSelect software.

Orenco Automatic Distributing Valve Assemblies For Wastewater Effluent Systems Introduction Orenco's automatic distributing valve assemblies, pressurized with small high -head effluent pumps, are useful for distributing effluent to multiple zones. These zones can be segments of sand filter manifolds, drainfields, or other effluent distribution systems. Distributing valve assemblies can substantially simplify the design and installation of a distribution sys- tem and reduce installation costs. This is particularly true where a distributing valve assem- bly is used instead of multiple pumps and/or electrically operated valves. Additionally, a reduction in long term operation and maintenance costs is realized due to a reduced size and/or number of pumps. More even distribution can be achieved on sloping sites by zoning laterals at equal elevations. This eliminates drainback to lower lines and the unequal distrib- ution of effluent that occurs at the beginning of a cycle. Valve Operation The valve itself has only a few moving parts, requires no electricity, and alternates automati- cally each cycle. Refer to Figure 1 for the following valve operation description. The flow of the incoming effluent forces the rubber flap disk 0 to seat against the valve bottom f . The opening © in the rubber flap disk aligns with an opening in the valve bottom to allow flow to only one valve outlet. The stem 0 houses a stainless steel spring which pushes the rubber flap disk away from the valve bottom after the flow of effluent stops. The stem acts as a cam follower and rotates the rubber flap disk as the stem is raised and lowered through the cam ©. The force from the flow of effluent pushes the stem down through the cam and the stainless steel spring pushes the stem back up through the cam when the flow of effluent stops. Each linear motion of the stem allows the rubber flap disk to rotate half the distance necessary to reach the next outlet. When there is no flow, the rubber flap disk is in the "up" position and is not seated against the valve bottom. Figure 1: 6000 Series Valve Orenco Systems° Incorporated 1-800-348-9843 NTP-VA-1 Rev. 1.2, ©11/03 Orenco Systems', Inc. Page 1 of 6 Figure 2: Orenco Distributing Valve Assembly (6000 Series Valve) The Distributing Valve Assembly The Orenco Automatic Distributing Valve Assembly combines the distributing valve itself and sever- al other components to give a complete preassembled unit that is easy to install, monitor, and main- tain. Figure 2 shows a complete assembly. Because distributing valves with several outlets can be difficult to line up and glue together in the field, the discharge lines in the assemblies are glued in place at Orenco. The unions (1) allow removal and maintenance of the valve. The clear PVC pipe sections (2) give a visual check of which discharge line is being pressurized. The inlet ball valve (3) allows a quick, simple method to test for proper valve cycling. The ball valve also stops the flow of effluent in case the pump is activated unexpectedly during maintenance or inspection. Check valves may be necessary on the discharge lines. Use of check valves is discussed in the valve positioning section. Valve Assembly Hydraulics Liquid flowing through the valve assembly must pass through fairly small openings and make several changes in direction. Because of this, headlosses through the valve assembly are fairly high. Table 1 gives the headloss equations for several different assemblies and Figure 3 shows the graphical repre- sentations of these equations. Orenco recommends that high -head turbine pumps be used to pressur- ize the valve assemblies to ensure enough head is available for proper system operation. High -head turbine pumps are also recommended because the use of a distributing valve usually requires more frequent pump cycling. The high -head turbine pumps are designed for high cycling systems and will outlast conventional effluent pumps by a factor of 10 or more in a high cycling mode. Furthermore, the high -head turbine pump intake is 12 inches or more above the bottom of the pump and tends to prevent any settled solids from being pumped into the distribution valve and obstructing its opera- tion. A minimum flow rate through the distributing valve is required to ensure proper seating of the rubber flap disk. Minimum flow rates for the various models are given in Table 1.

However, because of the mechanical movements of the valve, it is necessary to take steps to prevent solids from reaching the distributing valve that may impede the operation of the valve. Orenco Biotube® Pump Vaults — when properly sized and installed — provide the necessary protection to prevent valve malfunction. The Biotube® pump vault accepts effluent only from the clear zone between a tank's scum and sludge layers and then filters this effluent through a very large surface area screen cartridge. Without this protection in effluent systems, the valve has very little chance of reliable long-term operation. NTP-VA-1 Rev. 1.2, ©11/03 Orenco Systems", Inc. Page 3 of 6 Valve Positioning The physical position of the valve in relation to the pump and the discharge point is very important for proper valve operation. The most reliable operation occurs when the valve is placed at the high point in the system and as close to the pump as possible. The transport line between the pump and valve should be kept full if possible. If the line is empty at the beginning of each cycle, pockets of air during filling can cause random rotation of the valve. The valve is particularly vulnerable to this erratic rotation with empty lines that are long and not laid at a constant grade. An ideal valve loca- tion is shown in Figure 4. If the final discharge point is more than about 2 feet above the valve and the system does not drain back into the dosing tank, check valves should be installed on the lines immediately following the valve and a pressure release hole or line should be installed just prior to the valve. This pressure release hole or line can go into a return line to the dosing tank or to a "minidrainfield" near the valve. In order for the valve to rotate reliably, no more than about 2 feet of head should remain against the valve to allow the rubber flap disk to return to its up position. In many cases, it may take from one minute to several minutes for the pressure in the valve to be lowered enough for proper rotation to occur. Special care should be taken when installing systems controlled by programmable timers to ensure cycling does not occur too rapidly. Figure 5 illustrates a valve assembly using check valves. Pumping downhill to the valve should be avoided unless the transport line is very short and the ele- vation between the discharge line out of the tank and the valve is less than about 2 feet. If the valve is located many feet below the dosing tank, random cycling may occur while the transport line drains through the valve at the end of the cycle. A pressure sustaining valve located just before the distrib- uting valve may overcome this problem in some instances.

Page 4 of 6 System Startup Refer to the Hydrotek Valve booklet that is provided with the distributing valve assembly for the sequencing of the valve outlets. The transport line should always be flushed with clean water before installing the valve. Any sand, gravel, or other foreign objects that may have been in the pipe during installation can easily become lodged in the distributing valve, causing malfunction. With the pump running, alternately close and open the ball valve on the distributing valve assembly to check proper rotation of the valve. (Note: If check valves are used on the lines after the distribut- ing valve, the pump may need to be turned on and off to allow the pressure to be released from the valve.) If visual operation of which zone is operating is not possible, watch the clear pipe on each line for indication of which zone is operating.

Troubleshooting 1. PROBLEM: Valve does not change or cycle to next zone or outlet CAUSE: The stem and disk assembly is not rotating when water flow is turned off and then back on. SOLUTION 1: Ensure that there is no debris inside the cam. Clean and carefully reinstall the cam. SOLUTION 2: If fewer than the maximum number of outlets are being used, check the installation of the cam. Ensure that the stem and disk assembly is not being held down by an improperly installed cam. Refer to the cam replacement instructions. NTP-VA-1 Rev. 1.2, ©11/03 Orenco Systems`, Inc. Page 5 of 6 SOLUTION 3: SOLUTION 4: SOLUTION 5: SOLUTION 6: Remove the valve top and check for proper movement of stem and disk assembly. Check for and remove any debris or foreign objects that may jam or retard the movement of the disk. Check for freedom of movement of stem and disk assembly up and down over the center pin in bottom of valve. Scale deposits may build up on the pin and hold stem and disk assembly down. Clean pin and again check for freedom of movement. Be sure that all operating outlets are not capped and that the flow to operating zones is not restricted in any manner. This would cause pressure to build up in the valve and lock the stem and disk assembly in the down position. The backflow of water from uphill lines may be preventing the valve from cycling properly. This can happen when the valve is placed too far below an elevated line. If the valve cannot be placed close to the high point of the system, a check valve should be installed near the valve in the outlet line that runs uphill from the valve and a drain line installed just prior to the valve to relieve the pressure. 2. PROBLEM: Water comes out of all the valve outlets CAUSE: SOLUTION 1: SOLUTION 2: SOLUTION 3: 3. PROBLEM: CAUSE: Stem and disk assembly not seating properly on valve outlet. Check for sufficient water flow. A minimum flow rate is required to properly seat the disk as shown in Table 1. Remove the valve top and check the inside walls to ensure that nothing is interfering with the up and down movement of the stem and disk assembly inside the valve. Make sure that the operating outlets are not capped and that the flow to the operat- ing zones are not restricted in any manner. Valve skips outlets or zones Pumping into an empty transport line — especially downhill — may cause the valve to skip outlets from pockets of air allowing the rubber flap disk to raise during a cycle. SOLUTION 1: Keep the transport line full. SOLUTION 2: If the line must remain empty between cycles, use a larger diameter transport line laid at a constant grade to prevent air pockets from forming. CAUSE: SOLUTION 1: The stem and disk assembly is being advanced past the desired outlet. Ensure that the correct cam for the desired number of zones is installed and that the outlet lines are installed to the correct outlet ports of the valve as indicated by the zone numbers on the top of the cam.

Valve actuation is accomplished by a combination of pressure and flow. Automatic Distributing Valve Assemblies allow the use of smaller horsepower pumps on large sand filters and drainfields. For example, a large community drainfield requiring 300 gpm can use a six -line Valve Assembly to reduce the pump flow rate requirement to only 50 gpm. C;renco only warrants Automatic Distributing Valves when used in conjunction with High -Head Effluent Pumps with Biotube® Pump Vaults to provide pressure and flow requirements, and to prevent debris from fouling valve operation. An inlet ball valve and a section of clear pipe and union for each outlet are provided for a complete assembly that is easy to maintain and monitor.
