El Jebel Concrete and Excavation installed the system. The existing septic tank was abandoned by pumping the tank and crushing the top, bottom, and sides and filling in the void with onsite materials. The existing STA was abandoned in place. The OWTS design is based on 3-bedrooms. An average daily wastewater flow of 450 GPD was used. A new 4-inch SDR-35 sewer line was installed exiting the residence with a double-sweep clean out and a minimum 2% grade to the septic tank. An additional clean out was added for use as an Recreational Vehicle (RV) dump. No chemicals should be introduced into the OWTS, and use should be limited. The system installation included a 1000-gallon, two-compartment Norwesco® 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 two gravelless chamber beds. The distribution box is accessible from grade with flow equalizers installed on each outlet pipe in the distribution box to assure equal flow to each bed. A 4-inch diameter SDR-35 level manifold was installed to connect each row of the chamber beds. Each chamber bed consists of 4 rows of 7 ‘Quick 4’ Infiltrator® chambers (28 chambers in each bed) for a total 56 chambers and 672 square feet of infiltrative area. Inspection ports were installed at each corner of the bed. 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.
