Design Calculations OWTS The design flow is calculated as follows for a single family onsite wastewater treatment system (OWTS). The treatment capacity is designed for and equivalent 5 -bedroom residence. From the Regulation 43 usage table : Minimum population based on the first 3 bedrooms @ 2 persons per bedroom & 2 additional bedrooms @ 1 person per bedroom= 8 persons. Gallons per day per person =75 gal/person/day, No peaking factor Max. Design flow (Qd)gallons/day = (# of people) x (avg. flow)gal/person/day. Design flow Qd = 8 persons*75ga1/person/day=600 gpd Septic Tank Design: Use a 1250 gallon, two compartment concrete septic tank & a 500 gallon dosing tank with a duplex system effluent pump. Tanks shall be installed with concrete 30" risers and lids to the finish grade surface. Sub Surface Conditions and Testing: Subsurface soil investigations and USDA soil texture method tests were performed by Sopris Engineering. The soils in the area of the proposed absorption field were sampled and characterized by application of the USDA soil texture method analysis. The soils were tested to determine the hydraulic loading rate and to confirm the appropriate absorptive surface level suitable for conventional absorption systems in native soils. The soils below 6 to 12 inches of topsoil consist of medium dense sandy loam to loam soil with gravels to 6 feet below the surface. The underlying soils are composed of mixed alluvial materials consisting of gravels & cobbles in a sand matrix. The soil appears to be consistent across the proposed STU field. The native soils sampled from 2-3 feet below the surface are characterized as a soil type 2A consisting of sandy loam to loam texture with granular structure. This soil has an effective loading rate for conventional soil treatment of 0.5 Gal/S.F./day for a level 1 conventional treatment system. The equivalent percolation rate is assumed to be 20-40 minutes per inch. No free water was encountered in excavations on site. Groundwater levels are expected to be below 10 feet from the existing surface grades. The soils are suitable for a conventional shallow absorption field consisting of gravelless infiltration chamber units. Treatment -Soil Treatment Unit/ Absorption System Design: The treatment/absorption field is designed based on utilizing the effective Long Term Acceptance Rate (LTAR) for the native soils and the application of appropriate loading factors for a soil treatment unit system utilizing pressure dosed distribution to gravelless chamber trenches and use of water saving fixtures. The new treatment system and absorption field will consist of pressure distribution of septic tank effluent via pressure pipe to a manifold connected to individual chamber trenches with treatment across the native soil absorptive surface. Long Term Acceptance Rate (LTAR) Considering the application of the new state regulation 43: Receiving Wastewater Treatment Level 1; loading rate for Sandy loam to loam is (0.5 gal./S.F./day) for soil type 2A.; Loading factors; (Table 10-2, Pressure Dosed trenches = 0.8) and (Table 10-3, gravelless chambers = 0.7) A(sf) = Qd .: A = Area; LTAR LTAR = 0.5 Gal/S.F./day for loamy sand Qd = flow (gal/day) = 600 gpd L.F.1=0.8 Pressure Dosed Trenchs L.F.2=0.7 Chambers A(sf) = 600gpd x .8 x 0.7 = 672 S.F. 0.5 Gal/S.F./day Number of quick -4 chambers: 672 S.F = 56 chambers Use 56 chambers 12 S.F./Chamber Use 56 Quick -4 chambers in four trenches 58' long by 3' wide with 14 chambers units per trench plus two end caps as delineated on the plan. The septic tank effluent will be pressure dosed to the head of each chamber row via individual distribution pipes from a distribution box. additional soil evaluation will be performed during construction to verify the soils in the excavation.
