PifCo installed the system. The OWTS design is based on 4-bedrooms. An average daily wastewater flow of 525 GPD was used. A 4-inch diameter sewer line with a double sweep clean out and minimum 2% fall to the septic tank exits the residence. The system installation included a 1250-gallon, two-compartment Valley Precast concrete septic tank with an effluent filter on the outlet tee. This filter must be cleaned annually, or as needed. Risers bring the manhole lids to grade for access. Effluent gravity flows to a distribution box, and then to six gravelless chamber trenches. The distribution box was accessible from grade and has flow equalizers installed on each outlet pipe in the distribution box to assure equal flow to each trench. Each trench consists of 15 ‘Quick 4’ Standard Plus Infiltrator® chambers for a total of 1080 square feet of infiltrative area. There was at least 4-feet of undisturbed soil between each trench. Inspection ports were installed at the beginning and end of each trench. Ports may be cut to grade and placed in sprinkler boxes for access. 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 the new sewer line and cleanout adjacent to the residence, the new concrete 1,250‐gallon two‐compartment septic tank, the new effluent line, the distribution box, and the six gravelless chamber trenches. The septic tank and distribution box were installed level with access brought to grade. At the time of our site visit, the contractor had not installed the inlet tee, the outlet tee, nor the effluent filter in the tank. The contractor submitted photographs at a later date that showed these components installed as required. The trenches were level, with 4‐feet between the trenches. The trenches consisted of 15 Infiltrator Quick4 chambers per trench (90 total chambers, 1,080 ft2 total STA). Additionally, inspection ports were present at each end of each trench. In our opinion, this system was installed in general conformance with Garfield County OWTS Regulations. Please submit an As‐built drawing of the system when available. No further action or review from Garfield County Environmental Health is required regarding this permit. Thank you, Edward R. “Ted” White, P.E.
