Sacred Ground Excavating installed the system. The existing OWTS serving the 1-bedroom cabin was abandoned. Canyon Creek runs to the west of the cabin within the western property boundary. The new septic tank location is within the 50-foot setback to the creek, but not closer than the existing ejector chamber 1. An existing irrigation and ditch and pond are located greater than 50-feet from the STA to the west. It appeared over-flow may have occurred in the past, so a berm was constructed to protect the STA should over-flow occur in the future. The OWTS design is based on 1-bedroom 2. An average daily wastewater flow of 150 GPD was used. The sewer line exiting the cabin was replaced with minimum 4-inch diameter SDR-35 sewer line with a double-sweep clean out and minimum 2% grade to the septic tank. The system installation included a 1000-gallon, two-compartment Infiltrator® poly septic tank with an Orenco® Biotube Effluent Filter followed by a 500-gallon, Infiltrator® poly single-compartment with an Orenco® Biotube Pump Vault and an Orenco® PF3005 pump. There are filters in the second compartment of the primary septic tank and the pump chamber that must be cleaned annually, or as needed. The floats were set to dose approximately 60 gallons each pump cycle. The control panel for the pump is located within line of sight of the septic tank. Valley Precast out of Buena Vista performed start-up of the pumping system. A 1.5-inch diameter Schedule 40 pump line was installed from the pump to the manifold connecting the laterals in the STA. This pump line must had minimum 1% grade for proper drain back into the tank after each pump cycle. 1 Garfield County On-Site Wastewater Treatment System Regulations, Table 7-1, Note: states “For repair or upgrading of existing OWTS where the size of lot precludes adherence to these distances, a repaired OWTS must not be closer to setback features than the existing OWTS, as reviewed and approved by the local public health agency.” 2 Garfield County On-Site Wastewater Treatment System Regulations 43.6 A. 2. c. “…The minimum design flow for the repair or replacement of an OWTS of an existing one-bedroom home must be for one- bedroom unless bedrooms are added.” Effluent is pressure dosed to a gravelless chamber bed with two rows of 13 ‘Quick 4’ Standard Plus Infiltrator® chambers, for a total of 26 chambers and 312 square feet of infiltrative area. A level 1.5-inch diameter manifold connects 1.5-inch diameter laterals, which were hung with zip ties from the underside of the chambers. Laterals have 5/32-inch diameter orifices facing up, with the exception of the first and last holes facing down for drainage. Orenco® Orifice Shields were placed under each downward-facing orifice. The orifices were placed 3-feet on center. Each lateral ends in a 90 degree ell facing up with a ball valve for flushing. Valves were placed in a valve box, accessible from grade, for access. Inspection ports were placed at the beginning and end of each trench. Ports may be cut to grade and covered with a valve box 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.

The STA consists of two rows of 11 ARC 36 chambers per row (22 chambers total). The new tanks were installed level with access to grade. The chamber rows and the manifold were installed level. Observation ports were installed at each end of each row. 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.
