Cuc Construction installed the system. The existing septic tank was pumped and filled with road base. The existing soil treatment area (STA) was abandoned in place. New 4-inch diameter SDR-35 sewer pipes were installed from the foundation to the new septic tank. The system installation included a 2000-gallon, two-compartment Valley Precast concrete septic tank, followed by a 500-gallon, single-compartment concrete tank with an Orenco® ProPak pumping system and PF5005 pump. The filter in the pump tank must be cleaned annually, or as needed. The floats were set to dose approximately 90 gallons each pump cycle. The control panel is located on the north side of the residence, under the deck, within line of sight of the septic tank. Valley Precast out of Buena Vista performed start-up on the pumping system. A 1.5-inch diameter Schedule 40 pump line was installed from the pump to an Orenco® automatic distributing valve (ADV), model 6402. The ADV was placed a high point in the system and placed in what appeared to be a modified water tank. The ADV could have been installed at a higher elevation, but there was a miscommunication and the installer thought the grade could not be more than 1% for drain back. The way the ADV was installed with 1% drain back will work, although access is less ideal because of burial depth. Effluent was pressure dosed through 1.5-inch diameter pipes to two beds, each with 3 rows of 15 ‘Quick 4’ Standard Plus Infiltrator® chambers, for a total of 90 chambers and 1080 square feet of infiltrative area. There was at least 6-feet of undisturbed soil between each bed. Effluent was pressure dosed to a 1.5-inch diameter level manifolds. Laterals (also 1.5-inch diameter), 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. The orifices were drilled 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 in 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. ALL SERVICE septic, LLC 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 of the expertise of the installer, soil type, and weather conditions. Please call with questions.
