Silt Mesa Excavating installed the system. The OWTS design is based on 2-bedrooms in the new residence and 1-bedroom in the Accessory Dwelling Unit (ADU). An average daily wastewater flow of 450 GPD was used. The existing OWTS serving the existing residence was abandoned. The existing seepage pit serving the ADU was also abandoned. The existing sewer line and existing 1250-gallon, two-compartment Copeland Concrete septic tank serving the ADU remains in use. The inlet sanitary tee was present, and a new effluent filter was installed on the outlet of the existing septic tank. This filter must be cleaned annually, or as needed. A new 4-inch diameter Schedule 40 sewer line was installed from the existing septic tank with a minimum 1% fall to the sewer line exiting the new septic tank serving the new residence. A new, 4-inch diameter Schedule 40 sewer line with a double-sweep clean out was installed with a minimum 2% fall to the new septic tank. The system installation included a 1000-gallon, two-compartment Infiltrator® poly 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 4-inch diameter SDR-35 level manifold connecting 4 rows of 14 ‘Quick 4’ Standard Plus Infiltrator® chambers for a total of 56 ‘Quick 4’ Infiltrator® chambers and 672 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. 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.
