Savage Excavation installed the system. The OWTS design is based on 1-bedroom with 3 future bedrooms proposed for a total of 4 bedrooms. An average daily wastewater flow of 600 GPD was used. The 4-inch diameter SDR-35 sewer lines exiting the residence and Barn/Office have double-sweep clean outs and a minimum 2% grade to the septic tank. Plumbing in the Barn/Office are an auxiliary use to the main house. The sewer line has a clean out at least every 100-feet. The system installation included a 1500-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 must bring the manhole lids to grade for access. Effluent will gravity flow to a distribution box, and then to four GeoMat™ trenches. The distribution box was accessible from grade with flow equalizers installed on each outlet pipe in the distribution box to assure equal flow to each trench. Each 36-inches wide trench has a minimum of 6-inches of sand filter material. A gradation of the sand media is enclosed. GeoMat™ sheets were placed on top of the sand filter material the entire length of the trench. A 4-inch diameter perforated pipe was placed down the center of the GeoMat™, under the top layer of fabric. The STA consists of 4 trenches, each with 60 linear feet of 39-inch wide GeoMat™ for a total of 240 linear feet and 720 square feet. There was at least 4-feet of undisturbed soil between each trench. Inspection ports were installed at the beginning and end of each trench. The front inspection port was placed to the side of the GeoMat™ and the end inspection port was tied onto the end of the lateral. 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.
