Tate Civil installed the system. The new OWTS design is based on 2-bedrooms. An average daily wastewater flow of 300 GPD will be used. The 4-inch diameter, SDR-35 sewer line exiting the residence has a double-sweep clean out and a minimum 2% grade to the septic tank. At the time of our inspection, there were two 90-degree angles before the septic tank; one just after the clean out and the other at the southeast corner of the residence. Both were replaced with two 45-degree angles after our inspection, and these were verified by you, the property owner (see photo below). The system installation included a 1000-gallon, two-compartment Valley Precast concrete septic tank with an Orenco® Biotube Pump Vault and an Orenco® PF3005 pump in the second compartment of the septic tank. The floats were set to dose approximately 70 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. Effluent is pumped through a 1.5-inch diameter pump line to a level 1.5-inch diameter manifold. The manifold connects three laterals on a 12’ x 38.5’ bed. A minimum of 2-feet of sand filter material was installed in the over-excavated footprint. Laterals are 1.5-inches in diameter with 5/32-inch diameter orifices facing down, spaced 2.5-feet on center. Laterals used to disperse the effluent were surrounded by washed coarse screened gravel. Each 1.5-inch diameter lateral ends in a sweeping ell facing up with a ball valve for flushing. Valves were placed in a 10-inch sprinkler box for access. Laterals were covered by a soil separation fabric and at least 1-foot of topsoil or other suitable soil able to support vegetative growth. Inspection ports were placed at each corner of each bed. Ports were 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.
