The OWTS is designed for a maximum 4-bedroom capacity to serve potential future needs. Therefore based on the total peak design capacity the maximum residential population is 7 persons. From County adopted State Regulation 43, Design Flow Criteria: Minimum population is based on 2 persons per bedroom for the first 3 bedrooms = 6 persons and 1 person per bedroom for each additional bedroom. Therefore: design population is 3 bedrooms x 2 persons+ 1 bedroom x 1 person = 7 persons total. Gallons per day per person =75 gal/person/day, No peaking factor Design capacity = Max. Design flow (Qd)galIonsjday = (# of people) x (avg. flow)gal/person/day. + - Desi n flow Qd - 7 75 - 525 d Q p g g Septic Tank Design: 2-Day detention time = 525 x 2 = 1,050 gallons required. Use a minimum 1,250 gallon two -compartment primary septic tank or for pressure dosed system use a minimum 1,500 gallon two -compartment tank with a bio-tube high head pump dosing assembly. Sub Surface Conditions and Testing A subsurface soil investigation and site assessment was performed by Sopris Engineering in on February 4, 2022. The soils in the proposed field envelope area were sampled and characterized by application of the USDA visual/tactile soil texture method analysis from samples in shallow hand dug excavations and nearby embankment cuts. The shallow soils in these excavations were sampled, observed and tested at 1, 2 and 3 foot depths.The soils below nil to 3 inches of topsoil consist of medium dense gravelly sandy silt loam with scattered cobbles to 3 feet below the surface. Two profile pits were excavated on site in support of the foundation design nearthe northwest and southeast corners of the proposed building envelope. The medium dense soils observed from 1 to 7 feet in the NW test pit consists of loamy sand to sandy loam with some gravels. The medium dense soils observed from 1 to 7 feet in the NE test pit Consists of sandy silt loam with some gravels and cobbles. The primarily Type 2 soils in both pits have rock content less than 35%. The native soils sampled from 1-3 feet below the surface near the proposed field are characterized as a soil type 2 soil consisting of slightly gravelly sandy silt loam texture with moderate granular structure containing approximately 30% rock content. This soil has an effective loading rate for conventional soil treatment of 0.6 Gal/S.F./day for a level 1 conventional treatment system. The equivalent percolation rate is assumed to be 10-20 minutes per inch. The soils become increasingly rocky at depths below 5.5 feet. Soils below 5.5 feet are characterized as a USDA rocky soil R1 type 2 consisting of dense rocky sandy loam texture of granular structure with approximately40% rock and gravel being less than 3/4 inch and containing less than 20% cobbles and small boulders in the sandy loam matrix. In order to provide optimal treatment with respect to soil conditions, a pressure dosed STA utilizing a 24-inch depth of filter sand media will be installed to provide for an enhanced treatment level TL-3 system. No free water is expected to be encountered within the field excavations. Groundwater levels are expected to be below 6 feet from the existing surface grades. Additional observations and soil evaluation will be performed during construction prior to placement of the distribution and sand filter media materials, by Sopris Engineering in the area of the proposed treatment/absorption field and tank to inspect the soils and and provide installation guidance . The soils will be further observed to determine the presence of any unsuitable soil or other Conditions in orderto assist the contractor in installing the design material in the in -situ native soils. If any adjustments to design or installation recommendations are necessary notice will be made to County EHD and applicable revisions to design/Construction plans and report will be submitted. All conditions and installations will be included in the As -Constructed documentation. Sand Filter Trenches Treatment Unit/ Absorption System Design The treatment/absorption field is designed based on utilizing the effective Long Term Acceptance Rate (LTAR) for an intermittent sand filter treatment system utilizing pressure dosed distribution laterals in trenches and gravelless Chamber units as spray shields.. The new treatment system will consist of a fully pressure dosed sand filter treatment System with a 24-inch layer of filter sand (ASTM-33, "washed ASTM-33 Concrete sand") in individual trench configuration. Long Term Acceptance Rate (LTAR) Considering the application of the new state regulation 43: Receiving septic tank effluent, the treatment level for intermittent sand filters is considered TL3 for the minimum 24" depth of treatment media with the upper infiltrative surface being at least 4-feet above a limiting layer; Maximum hydraulic loading rate forTL1 effluent applied to "Secondary Sand Media" in an unlined sand filter is 0.8 gal./sq.ft./day, or the long term acceptance rate of the receiving soil Type 2 and or R-1 forTL3 (1.1 gal./S.F./day) (Table 10-1 &10-1A) whichever results in the larger area. The maximum Loading rate is therefore 0.8 gal./sq.ft./day Loading factors; (Table 10-2, pressure dosed trench application = 0.8 } A(sf) = Qd x LF1 = A = Area; LTAR LTAR = 0.8 Gal/S.F./dayfor 2nd sand, ASTM-33, " Concrete sand" Qd = flow (gal/day) = 525 gpd LF1=0.8 pressure dosed trenches A (sf )= 525 gpd x 0.8 = 525 S.F. 0.8 Gal/S.F./day Excavate four 44' long by T wide trenches to a maximum N depth below finish grade. Backfill with 24-inches of ASTM-33, Concrete sand. Install a custom perforated 1.5-inch distribution lateral on top of the sand layer in each trench and Cover with 8 Arc-36 biodiffuser chambers per trench for use as pressure dose spray shields, as delineated on the plan. The treatment field will be installed with a total of 4 perforated distribution laterals pressured dosed bythe high head pump assembly in the second compartment of the the septic tank through a transport pipe connecting to a common 1.5" manifold pipe with connections to head of each trench distribution lateral. The septic tank effluent will be equally dosed through each individual 1.5" custom perforated pressure distribution lateral running the length of each trench centered on top of the sand filter material. Each trench will be constructed with 24-inches of washed filter sand below the Chamber spray shields. TESTING. INSPECTIONS AND CONSTRUCTION MANAGEMENT 1.
