Alpha Excavation installed the system. This is a repair to an existing system where the existing soil treatment area (STA) encroached on the minimum required setback to the existing well. Garfield County OWTS Regulation Table 7-1 NOTE: The minimum distances shown above must be maintained between the OWTS components and the feature described. … 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…” The new STA was verified at approximately 135-feet from the well and 46-feet from the ditch. OWTS design is based on 3-bedrooms. An average daily wastewater flow of 450 GPD was used. The existing sewer line from the house to the septic tank and existing concrete septic tank remained in use. A new inlet sanitary tee, effluent filter, and risers were installed on the existing septic tank. The effluent filter must be cleaned annually, or as needed. A new 4-inch diameter Schedule 40 sewer line with minimum 1% fall was installed from the septic tank to the new STA. Since the length exceeded 100-feet, a clean out was added. The system installation included a 4-inch diameter SDR-35 level manifold installed to connect each row of the chamber bed. The chamber bed consists of 4 rows of 14 ‘Quick 4’ Infiltrator® chambers for a total of 56 chambers and 672 square feet of infiltrative area. Inspection ports were installed at each corner of the bed. Ports were cut to grade. 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.
