Since the preschool facility will not contain a full service cafeteria, the per capita wastewater demand will be 15 -gallons per day for students and staff, (CDPHE Regulation 43, Table 6-2, Rev. 6/2013). / Therefore, the expected Daily Wastewater Design Capacity is as follows: 1'Ria';cite S 1 q D' Ptiernintscli 1 1 1 1 1 1 1 Ili I 1418818` 1. 1 1 1 1 1 1 1 1 1 1 1 1 I 1 1 1 1 1 1 1 1 1 1 1 1 1 1[ 1 1 4 Perc Test Hole Location tll1� Nis /i 4" SDR5� I I I I I I f l NOTE: 1 t 1 1 1 1 t t t 1 1 1 1 I I I I I 1 1 1 This layout and design is for con ruction based on actual percolation test ho x 1 1 1 1 1 1 1 4 locations.

The tank will collect the wastewater the preschool facility. The septic tank will discharge by gravity to a concrete vault. Effluent from the vault will be pumped to the soil treatment area located to the northwest of the preschool building. The soil percolation rate was determined from percolation testing at the New Creation Church property at the spots indicted and will be used. The design soil percolation rate will be 34 -minutes per inch. Additional soil percolation testing at the location of the new soil treatment area will be confirmed by the design engineer during construction. Should the actual soil percolation rate vary significantly from the design percolation rate, the required soil treatment area size will be recalculated by Colorado River Engineering, Inc.. Design Percolation Rate: 34 min/inch Design Long Term Acceptance Rate (LTAR): 0.5 gal/sq.ft./day The required Soil Treatment Area (STA) for a gravel type leach area is calculated using the following formula: STA = Design Flow / LTAR Therefore, STA = 1380-gpd / 0.5 gal/sq.ft./day STA = 2760-sq.ft. OWTS regulations allow a maximum reduction of 30% of the required soil treatment area for a gravelless type design in a Trench configuration, (CDPHE Regulation 43, Table 10-3, Rev. 6/2013). The proposed system is a Trench configuration. Therefore, the required Soil Treatment Area = 2760 sq.ft. x 0.7 = 1932 sq.ft. AculA 1. 2oa` SF b#/) 4 Required number of standard Qln� nfiltt ato Units = 1932 sq.ft. / 1/7 sq.ft./unit = There shall be 8 Trenches with each beingieunits long for uniformity for a total of ye units for uniformity. 1$ 144 Minimum Horizontal Setbacks: Setback from Well 188 ft Setback from Existing System: 260 ft The above designed OWTS shall be installed to satisfy all minimum setbacks and design standards as described by Garfield County and Colorado State regulations and will be installed according to all manufacturers specifications and recommendations. If during construction the soil treatment area trenches are moved from the general location as shown, Colorado River Engineering, Inc. can be available to conduct site visits during construction to observe exposed soil types.
