Basis of design is for four. bedrooms with no tub over 100 gallons with a perc rate of 1.0 - 10.0 min./in. System area required is 660 s. f. as follows: and is supplied 1 row of 115 l.f. of 12" x 48" galleries at 5.9 s.f. per I.f. =678.5 s.f. Total Leaching Area =678,5 s.f. A 10OX reserve area has been supplied. MLSS required = HF(20) x FF(2.0) x PF(1.2) =48' MLSS supplied =114.0' J. All topsoil, stumps, and boulders must be removed from the area of the system. Silt fence shall be installed prior to any system, driveway, house construction or stump removal. 4. Town sanitarian must be nofffied before any pipes orappurtenancesarebackfilled. 5. There are no wells within 75' of this system. 6. Gravel fill shall be used to replace all topsoil and subsoil as required by the Town Sanitarian. Gravel shall be placed in 6"-8" lifts and shall be mechanically compacted. 7. 15elect Fill Material", placed within and adjacent to proposed leaching areas shall be comprised of clean sand and gravel, free from organic matter and foreign substances. The Ell material shall meet the following requirements unless otherwise approved by a professional engineer for use within the leaching area. a. The fill shall not contain any material larger than three (3) inches b. Up to 45X of the dry weight of the representativtia sample may beretainedonthe14sieve (This is the grovel portion of the sample). c. The material that passes the 14 sieve is than reweighed and the sieve analysis started. d: The remaining sample shall meet the following gradation criteriaSieveSizePercentpassing 4 100 10 70.E - 100' 140 10X - 50X 100 OX - 2OX 1200 ox - 5X The responsibility for the preparation of the leaching area utilizing select material" is that of the licensed installer. The installer shall take the necessary steps to protect the underlying naturally occurring soils from siltation once exposed. 8. There shall be no cuts within 50' of the downhill side of the system or within 25' of the sides of the system. There shall be no stumps or boulders buried within 50' of the downhill side of the system. There shall be no footing drains or stone placed around or under any proposed structure within 50' (down gradient) of the system. 9.

House, Septic System area and elevation shall be staked out by a surveyor prior to construction. House foot print believed to be accurate; however all construction stakeout for the house shall be based on owner supplied house plans. 11. In general, all construction practices, as per the State of Connecticut Department of Health Services guidelines, shall be adhered to. The following outlines some of the major procedures, but do not relieve the contractor from full compliance due to their lack of mention below: A. All topsoil, stumps, and boulders shall be removed from the area of the system and system fill. No machineryorvehiclesshallbeallowedontheexposednativesoil.

Gravel fill shall meet the specifications of Note 7 and be placed in accordance with Note 6. C. No tracks or heavy machinery shall be allowed in the stripped area until 12" of gravel fill is in place. 12. Septic tank manhole risers shall be required over each tank opening and shall be a minimum of 24" in diameter, and within 12" of finished grade 13. Site Investigation and subsequent foundation elevations are for the sole purpose of sanitary sewer design.
