Silt Mesa Excavation installed the system. The OWTS design was based on 4-bedrooms. An average daily wastewater flow of 525 GPD was used. Our original design dated October 4, 2020 addressed only the soil treatment area (STA). However, at the time of installation, the outlet side of the existing concrete septic tank was showing signs of deterioration and the tank was replaced after our installation observation visit. The septic tank installation was inspected by Garfield County Environmental Health Department personnel and documented in their final acceptance letter dated July 27, 2021. A 1500-gallon, two-compartment poly septic tank with an effluent filter on the outlet tee was installed. This filter must be cleaned annually, or as needed. The setback distance from the neighboring well to the northeast was verified as approximately 120-feet. Effluent gravity flows to a level manifold connecting four rows of 13 ‘ARC’ ADS chambers for a total of 52 chambers and 780 square feet of infiltrative area. Inspection ports were installed at each corner of the bed. Ports may be cut to grade and placed in sprinkler boxes for access. We recommend the STA be fenced off to reduce impact from livestock. The OWTS was generally installed according to specifications. This observation is not a guarantee of workmanship and/or parts and materials. CBO Inc. should be notified if changes are made to the OWTS in the future. Any additional OWTS construction must be according to the county regulations. LIMITS: Observations are limited to components that are visible at the time of the inspection. The installer must have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. The quality of the installation is dependent on the expertise of the installer, soil type, and weather conditions. Please call with questions. Sincerely, CBO Inc.

At the time of our site visit, the contractor had installed a new effluent line, a new manifold, and the four-row chamber bed. The manifold and chambers were installed level. The four chamber rows consisted of 13 ARC 36 chambers per row, for 52 total chambers and a total STA of 780 ft2. At the time of our first inspection, the existing septic tank was in a state of disrepair. The contractor temporarily repaired the existing tank. The homeowner opted to replace the existing tank. We visited the site on June 23, 2021, to observe the installation of the new tank. The contractor had installed the new 1,500-gallon, two compartment poly tank and made connections to the existing sewer line from the residence and to the effluent line to the new STA. The tank was installed level, with access to grade, and an effluent filter in the outlet tee. In our opinion, this system was installed in general conformance with Garfield County OWTS Regulations. No further action or review from Garfield County Environmental Health is required regarding this permit. Please provide an As-Built drawing of the system, when available, for our files.
