The purpose of our site visit was to inspect the installation of the OWTS – consisting of pressure-dosed, mound system. The system was installed in overall compliance with the septic system design, Drawing No. 18-3303OWTS.dwg, last updated on August 19, 2022. At the time of the inspection, we observed the following: They installed 1530 gallon, two-compartment, Infiltrator Poly Tank and IM540 Infiltrator Poly Tank, one-compartment with an Orenco PF500511 high-head pump assembly by Valley Precast. An effluent filter was installed in the second compartment of the 1530-gallon poly tank. The inlet of the tank had the Tee installed. The tank access ports had corrugated, plastic risers with secured, green, plastic covers. The covers were insulated and will be secured with nuts, bolts, and screws. The building sewer line was connected to the back of the residence, as shown on the attached as-built sketch. A cleanout was constructed on the building sewer line about 1.6 feet away from the house. The building sewer line was 4-inch diameter SDR35 PVC pipe. The two-compartment septic tank and the pump tank, were connected with about 44 feet of 4- inch diameter, SDR35 PVC pipe. The effluent line from the pump chamber to the center manifold of the mound system, was 1.5-inch diameter, SCH40 PVC pipe. The soil treatment area consisted of a mound system, consisting of a sand fill with a gravel distribution cell. The sand was from United Gravel Pit, was less than 30-days old, and it passed the classification for a secondary sand. The pressure dosing system consisted of six, 41-feet long, 1.25- inch diameter SCH40 pvc, distribution laterals, perforated at their inverts with 1/8-inch holes at 3- Heinbaugh Residence 602 Granite Springs Trail Project 18-3303 November 22, 2022 Page 2 of 2 P.O.

The center manifold 6 feet, 1.25-inch, SCH40 pvc. The ends of the laterals were equipped with flushing assemblies. A squirt test was performed during the inspection. Two inspection ports were installed, one on each side of the distribution cell, at about the middle between the laterals. The OWTS installation and the system start-up was done by Travor Dunsdon. The control panel for the pump was installed in the utility box attached to the foundation wall on the north side of the residence, as shown on the as-built sketch.

On October 27, 2018, we visited the subject property on Lot 4, Block 5, Cordillera Filing No. 34, 602 Granite Springs Trail, Eagle County, Colorado near Edwards, Eagle County, Colorado. The purpose of our site visit was to observe the site and select an area for the new, Onsite Wastewater Treatment System (OWTS). Buz Reynolds, The Reynolds Corporation, dug the profile holes. The proposed Onsite Wastewater Treatment System (OWTS) will consist of 1530 gallon, two-compartment, Infiltrator Poly Tank and IM540 Infiltrator Poly Tank, one-compartment with an Orenco Pump Assembly by Valley Precast. The septic tank will have an effluent filter in the second compartment. The Soil Treatment Area (STA) will consist a mound system. The mound system was designed partially in compliance with the Technical Guidance for Mounded Wastewater Treatment Systems and partially with the Wisconsin Mound System Guidance. According to the guidelines of the Technical Guidance for Mounded Wastewater Treatment Systems the maximum recommended linear loading rate for soil types 3A through 5 is in the range of 3.0 to 5.0 gpd/lf. With this rate the length of the proposed mound system was greater than the site. Due to the size of the site and relatively gentle to moderate slope of 8 percent we decided to use the Wisconsin Mound System Guidance, where the area of the distribution cell remained the same but the dimensions changed, thus allowing the mound system to fit on the site. The linear loading rate used in the final design was 7.2 gpd/lf. ! Preliminary Investigation G Address: 602 Granite Springs Trail, Cordillera, Colorado G Legal Description: Lot 4, Block 5, Cordillera Filing No. 34, Eagle County, Colorado.

SQUIRT TEST OF THE RESIDUAL HEAD ON THE MOUND LATERALS REMOVE THE END CAPS OF THE FLUSHING ASSEMBLY IN ORDER TO FLUSH THE LATERALS CLEAN FROM ANY DRILLING DEBRIS OR DIRT. PROVIDE ONE 1/8-DIAMETER HOLE IN A TEMPORARY CAP ON THE ENDS OF THE FLUSHING ASSEMBLY FOR THE SQUIRT TEST. RUN THE SQUIRT TEST TO MEASURE THE 5-FT RESIDUAL HEAD (+/-10%) AFTER THE TEST REMOVE THE TEMPORARY, PERFORATED CAPS AND REPLACE WITH THE PERMANENT CAPS. COVERING OF THE MOUND SYSTEM PLACE A FINER TEXTURED SOIL, SUCH AS CLAY OR SILT LOAM OVER THE TOP OF THE BED, TO A MINIMUM THICKNESS OF 6 INCHES. PLACE ADDITIONAL 6 INCHES OF GOOD QUALITY TOPSOIL OVER THE ENTIRE MOUND SURFACE. PLANT GRASSES ADAPTABLE TO THE CLIMATE OVER THE MOUND SYSTEM. PUMP SELECTION A PUMP CAPABLE OF DELIVERING 37GPM AGAINST 27 FEET OF HEAD CAN BE USED. THE ELEVATIONS BETWEEN THE PUMP INVERT AND THE MANIFOLD INVERT MUST BE FIELD VERIFIED. THE PUMPING SYSTEM MUST ALSO INCLUDE PUMP CONTROLS AND AN ALARM SYSTEM, AUDIBLE AND VISUAL. THE PUMP DOSING WILL BE ON DEMAND WITH 90 GALLONS PER DOSE. USE ORENCO, PF500511 HIGH HEAD EFFLUENT PUMP, 115/230V, 50GPM, 1 2 HP, OR EQUIVALENT, APPROVED BY THE ENGINEER. WHEN THE PUMP SHUTS OFF THE EFFLUENT LINE WILL DRAIN BACK INTO THE PUMP CHAMBER. THE PUMP SYSTEM MUST BE TESTED BEFORE THE FINAL INSPECTION OF THE SEPTIC SYSTEM AND A LETTER OF THE TEST SUBMITTED TO THE ENGINEER. INSPECTION PIPE INSTALL A 4 INCH DIAMETER INSPECTION PIPE ON BOTH ENDS OF THE GRAVEL BED. THE PIPE WILL BE OPEN ON THE BOTTOM. THE BOTTOM OF THE PIPE WILL BE AT THE SAME ELEVATION AS THE BOTTOM OF THE GRAVEL BED. THE BOTTOM 8 INCHES OF THE INSPECTION PIPE WILL BE PERFORATED. THE PIPE WILL BE COVERED WITH A VENT CAP.
