You, the property owner, installed the system. The OWTS design is based on 3-bedrooms. An average daily wastewater flow of 450 GPD was used. The 4-inch SDR-35 sewer line exiting the residence had a double-sweep clean out and a minimum 2% grade to the septic tank. The system installation included a minimum 1500-gallon, two-compartment Infiltrator® poly septic tank with an Orenco® Biotube 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 distribution box, and then to five gravelless chamber 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 trench consisted of 15 ‘Quick 4’ Standard Plus Infiltrator® chambers for a total of 75 chambers and 900 square feet of infiltrative area. There was at least 4-feet of undisturbed soil between each trench. Inspection ports were installed at the beginning and end of each trench. 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.
