IN -DRAIN SYSTEM DISPERSAL/ABSORPTION/TREATMENT BED TESTING, INSPECTIONS AND CONSTRUCTION MANAGEMENT 1. ADDITIONAL INSPECTIONS AND RECOMMENDATION WILL BE MADE BY THE ENGINEER DURING CONSTRUCTION TO APPROVE THE LAYOUT OF THE MOUNDED SAND FILTER BED SYSTEM, VERIFY INSTALLATION OF SPECIFIED MATERIALS AND OWS COMPONENTS. 2. PRIOR TO CONSTRUCTION OF THE PERMITTED SYSTEM THE ENGINEER SHOULD BE CONTACTED BY THE PROJECT MANAGER/CONTRACTOR WELL IN ADVANCE TO PROVIDE ADEQUATE TIME TO DISCUSS THE SYSTEM COMPONENTS WITH THE CONTRACTOR, ANSWER QUESTIONS, RESOLVE ANY CONFLICT ISSUES AND SCHEDULE INSPECTION SITE VISITS BASED ON CONSTRUCTION PROGRESS. A PRE-OWS CONSTRUCTION MEETING WITH THE ENGINEER, THE CONTRACTOR, ELECTRICIAN AND THE QUALIFIED INSTALLER IS REQUIRED PRIOR TO INSTALLATION OF THE OWS COMPONENTS. 3. REGULATIONS REQUIRE THAT THE DESIGN ENGINEER OF RECORD PERFORM SITE INSPECTIONS OF THE PERMITTED SYSTEM DURING CONSTRUCTION AND PROVIDE "AS -BUILT" DOCUMENTATION OF THE INSTALLED SYSTEM TO THE THE COUNTY AFTER CONSTRUCTION IS COMPLETE. WE RECOMMEND THAT INSTALLED OWS COMPONENTS BE SURVEYED TO OBTAIN REQUIRED AS -BUILT INFORMATION. 4. CONTRACTOR SHOULD DISCUSS ISSUES REGARDING SPECIFICATIONS, INSTALLATION AND OPERATION OF OWS MECHANICAL SYSTEMS AND CONTROLS WITH THE SUPPLIER/INSTALLER AND/OR THE ENGINEER. 5. OUR DESIGN AND RECOMMENDATIONS ARE BASED UPON OUR EVALUATION OF THE EXISTING AND PROPOSED SITE CONDITIONS AND INFORMATION SUPPLIED TO US BY OTHERS. IF SITE CONDITIONS ARE FOUND TO BE DIFFERENT FROM CONDITIONS ASSUMED OR INDICATED, WE SHOULD BE NOTIFIED TO EVALUATE ANY EFFECT ON THE PROPOSED OWS. Design Calculations Building C OWS The design flow is calculated as follows: Non -Profit Art and Education Facility Maximum No. fulltime Employee Staff= 5 persons Maximum Peak Day Transient Visitor Population = 100 persons From the State 1. S. D. S. Regulations: Max. Design flow (Qct) = # of people x (avg. flow) x 1.5 gal/person/day. Gallons per day per person for staff employees = 15 gall/person/day Gallons per day per person for Transient Visitors = 5 garl/person/day Qd=Staff Employees: 5 persons 0 15 gpd = 75x1.5 = 1.12.5 gpd Qd=Transient Visitors: 100 persons 0 5 gpd = 500x1.5 = 750 gpd Design flow Qd = 862.5 gpd Assume 870 gal/day Septic Tank Design V = 870 gal/day * 1.25 days = 1087 gallons. Use a 1500 gallon, three compartment septic tank with dosing basin. Percolation testing will performed by Hepworth Pawlok Geotechnical, Inc. in the location of the proposed treatment absorption field to verify design assumptions. The average percolation rate is estimated to be between 20-30 minutes per inch. A rate of 30 minutes per inch is used for design. Elgen ln-Drain/Geotextile Sand FllterTreatment System Area Design Average percolation rate of 30 minutes per inch. Standard absorption area equation yields: A (sf) = (Od *(t) where A = Area; 5 t = time in minutes per incrh=30mpi Qd = flow (gal/day) = 870 gpd A = = 870 *(30) 3 = 954 sq. ft. 5 Elgen In-Drain/Sand filterTreatment System Design for use of single pass secondary geotextile sand filter treatrrnent system. Apply sizing credit reduction of 5.4 SF equivalent absorption area per L.F. for full pressure dosed system w/ no other reductions in assumed flow. A(credit reduction)= A / 5.4 = 954 / 5.4 = 176 L.F. Each In -drain unit is 2 feet wide by 4 feet long. Number of Eljen In -Drain units required equals 176 L.F. / 4 FT = 44 units. Initial treatment surface area equal to 176 L.F. x 2 FT = 352 S.F. required Use 44 Eljen In -Drain units over approximately 540 S.F. of select sand 24" deep. Total treatment surface area equal to 44 units x 8 SF = 352 S.F. provided The total infiltrative surface area is 540 S.F. horizontal (arena of (2) 4' x 6' sand beds) TYPICAL YARD LANSCAPED SURFACE OR AGGREATE PAVED SURFACE 6" MIN. - 4" TALL/./BLUE BOARD 1F PTH OF COVER IS LESS THAN 3' EXCAVATED MATERIAL COMPACTED TO 90% STANDARD PROCTOR CLASS 6 ROAD BASE TRENCH CROSS-SECTION FOR SDR -35,26 OR HDPE PIPES N.T.S.

ALL SEWER LINES TO BE SDR -35 BEDDED IN CLASS 6, SDR -26 BEDDED IN SCREENED NATIVE OR SCHEDULE 40 P.V.C. PIPE BEDDED IN SCREENED NATIVE MATERIAL UNLESS NOTED OTHERWISE. 4. INSTALL A TWO-WAY CLEAN OUT ON THE SERVICE LINE FROM THE HOUSE. 5. THE CONTRACTOR SHALL ENSURE ALL SEWER LINES AND SEPTIC TANKS ARE WATERTIGHT. ANY POTENTIAL PLUMBING LEAKS SHALL BE REPAIRED TO AVOID EXCESSIVE WATER ENTERING THE SEPTIC SYSTEM. 6. THE SEPTIC TANK SHALL BE INSTALLED LEVEL ON COMPACTED EARTH. INSTALL WATERTIGHT RISERS AS NECESSARY TO BRING ALL REQUIRED ACCESS POINTS TO THE FINISHED SURFACE GRADE. 7. A SANITARY BAFFLE TEE IS REQUIRED ON THE SEPTIC TANK INLET AND OUTLET. INSTALL THE INLET AND OUTLET TEES PLUMB AND IN A POSITION TO ALLOW EASY INSPECTION AND MAINTAINANCE OF TANK FROM THE TANK RISERS. 8. WE RECOMMEND THE INSTALLATION OF A 4" EFFLUENT FILTER CONTAINED IN THE 4" BAFFLE OUTLET TEE OF THE SEPTIC TANK. THE FILTER SHOULD BE INSPECTED EVERY SIX MONTHS. THE EFFLUENT FILTER SHALL BE MAINTAINED AND CLEANED WHEN THE TANK IS PERIODICALLY PUMPED OR AS NECCESSARY. INSTALL A SUITABLE EXTENSION ON THE FILTER WITH A HANDLE TO BE WITHIN 6" BELOW THE ACCESS LID. 9. THE TREATMENT BED MUST BE MARKED AND PROTECTED TO PREVENT DAMAGE FROM VEHICULAR AND LIVESTOCK TRAFFIC. 10. THE ENTIRE TREATMENT BED SURFACE MUST BE SODDED OR RE -VEGETATED WITH GROUND COVER. 11. THE TREATMENT BED SURFACE MUST BE CROWNED TO DIVERT SURFACE DRAINAGE AWAY FROM THE BED. 12. THE DIMENSIONS SHOWN ON THE PLAN INDICATE MINIMUM AREA AND SEPARATION DISTANCES FOR THE OWS COMPONENTS. 13. THE BED SHALL BE LEVEL WITH DISTRIBUTION PIPES INSTALLED FOR EQUAL PRESSURE DISTRIBUTION. 14. THE BED SHALL BE OVER EXCAVATED TO ALLOW PLACEMENT OF A MINIMUM OF THE SAND TREATMENT LAYER.
