The Onsite Wastewater Treatment System (OWTS) was designed and installed to serve the five-bedroom residence on the above property. Additional information about the maintenance of your septic system needs can be accessed through our website links, provided on the Environmental Health Department’s septic system resource page. Be aware that changes in the use of your property or alterations of your building may require commensurate changes to, or relocation of, your septic system. Landscape features, trees with taproots, irrigation systems, and parking areas above the soil treatment area can cause a premature system failure. It is equally important that you notice and immediately repair dripping faucets and hissing toilets as this will certainly cause the system to fail. If you have any questions regarding this information, please contact us at (970) 328-8755 and reference the OWTS septic permit number.

The purpose of our site visits was to inspect the installation of the septic system for the proposed 4-bedroom main residence and 2-bedroom auxiliary unit (ADU). The systems were installed in overall compliance with the septic system design, Drawing No. 20- 3397OWTS.dwg, dated May 26, 2020, with minor revisions agreed upon during an on-site meeting on September 11, 2020, with you, Travis Nottingham, Hans Von, and Clair Lewandowski, REHS, Eagle County, Environmental Health Department. The revisions were needed due to shallow bedrock encountered in the upper trenches. During the meeting we decided to change the ADU soil treatment area configuration from trench configuration to a bed configuration, thus reducing the required footprint. ADU – OWTS For the OWTS for the 2-bedroom ADU, they constructed 1000-gallons, 3-compartment, concrete septic by Valley Precast with an effluent filter in the second compartment and siphon, model 316, in the third compartment. The tank access ports had corrugated, plastic risers with secured, insulated, green, plastic covers. The covers were secured with nuts, bolts and screws. All risers were 24 inches high. The cycle counter is mounted 2’ from third compartment manhole (where the siphon is located), on a wood post and it is battery operated, according to your email. The building sewer line was about 38 feet, 4-inch diameter SDR35 pvc, and was connected to the west side of the building with a cleanout at about 2.6 feet away from the building wall, as shown on the attached as- built drawing. The effluent line from the septic tank to the STA was 175 feet long, 4-inch diameter, sch40pvc, with three cleanouts along the line. One cleanout was installed at the beginning of the effluent line with a 3/16” hole drilled in the cap (per the manufacturer’s recommendations for the siphon operation). The second cleanout on the effluent line was constructed, at about 36 feet from the first, and the third cleanout was at about 80 feet from the second cleanout. The STA for the ADU was constructed with 54 Quick 4 plus infiltrator chambers in a bed configuration, with three rows of 18 chambers in each. In the first 20 feet of each of the rows of infiltrators, 20-foot section of 4-inch diameter, sch40 pvc, perforated at the inverts with ¼-inch holes at 36” intervals were Clem - Main Residence and ADU Project 20-3397 Page 2 of 2 October 25, 2020 P.O.

The system start-up was done by the installer, Nottingham Excavation & Trucking, Inc. MAIN HOUSE OWTS The 4-bedroom residence was not constructed at the time of the OWTS installation. They installed 1500-gallons, three compartments, precast, concrete, septic tank by Valley Precast with effluent filter in the second compartment and Model 316 Siphon for dosing in the third compartment. The tank access ports had corrugated, plastic risers with secured, insulated, green, plastic covers. The covers were secured with nuts, bolts and screws. All risers were 24 inches high. The effluent line from the siphon chamber to first infiltrator chamber of the soil treatment area, was about 175 feet long, 4-inch diameter, SCH40 pvc pipe with two cleanouts. One cleanout was installed at the beginning of the effluent line with a 3/16” hole drilled in the cap (per the manufacturer’s recommendations for the siphon operation). The second cleanout was constructed at about 85 feet from the first. The soil treatment area consisted of 105 Quick4 Plus Infiltrator chambers arranged in six trenches with 25 infiltrators in the first two, 22 in the third, 15 in the fourth, 13 in the fifth, and 5 in the last row. The rows of Infiltrator chambers were connected with serial distribution, with 4-inch diameter SDR35 pvc pipes. In the first row of infiltrators, a 20-foot section of 4-inch diameter SDR35 pvc pipe perforated with ¼-inch holes at 36- inch intervals was suspended from the top of the infiltrator chambers. The priming/startup of the siphon system and the construction of the cycle counter will be done after the house construction. There is no other warranty either expressed or implied.
