Tonka Excavation installed the system. The OWTS design is based on 4-bedrooms. An average daily wastewater flow of 525 GPD was used. The system installation included a 1500-gallon, two-compartment poly Infiltrator® septic tank with an Orenco® Biotube Effluent Filter on the outlet tee followed by a 500-gallon, single-compartment poly Infiltrator® pump chamber with an Orenco® Biotube Pump Vault and an Orenco® PF3005 pump. There are filters on the outlet side of the primary septic tank and in the pump chamber. These must be cleaned annually, or as needed. The floats were set to dose approximately 80 gallons each pump cycle. Valley Precast out of Buena Vista performed start-up of the pumping system. Effluent is pumped through a 1.5-inch diameter pump line from the pump chamber an Orenco® automatic distributing valve (ADV), model 6402. The ADV was placed at a high point in an insulated riser with access from grade. Effluent is pressure dosed through 1.5-inch diameter distribution pipes to two beds, each with two rows of 11 ‘ADS’ ARC 36 chambers, for a total of 44 chambers and 660 square feet of infiltrative area. There was at least 6-feet of undisturbed soil between each bed. Effluent is pressure dosed to two 1.5-inch diameter level manifolds and 1.5-inch diameter laterals, which 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. Orifices were drilled 3-feet on center. Each lateral ends in a 90 degree ell facing up with a ball valve for flushing. Valves may be placed in a valve box, accessible from grade, for access. Inspection ports must be placed at each corner of each bed. Ports may be 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.
