House sewers are laid on firm foundation at a minimurn grade of one-quarter inch per foot preferably without bends. At least one cleanout with a properly fitted plus: is to be provided. The house sewer shall allow for venting of gases from the sewage system. 2. House sewer construction including materials shall comply with the applicable requirements of the State Uniform Fire Prevention and Building Code contained in 9 NY6RR, Parts 903 through 907, inclusive, and Part 1250. 3. A minimum horizontal separation of 10 feet should exist between the house sewer and any water line. Where lines must cross, the water service line shall be at least 12 inches above the house sewer. If a water line must pass below the house sewer, the vertical separation must be at least 18 inches. 4. Suction waterlines shall never cross under house sewers or any other component of the sewage system. Distribution Devices 1. Gravity Distribution. The maximum length of absorption lines used in conjunction with gravity distribution shall be 60 feet. A. Distribution Box. a. For accessibility, it is necessary that the distribution box be located and have a removable cover not more than 12 inches below grade. Where, due to site conditions, a distribution box must be greater than 12 inches below the surface, an extension collar sholl be installed to within 12 inches of the surface. b. All outlets from the distribution box shall be at the some level to insure the even distribution of flow. c. To minimize frost action and reduce the possibility of movement once insta'.d, distribution boxes must be set on a bed of sand or pea gravel at least 12 inches thick. d. The drop between inlet and outlet inverts shall be at least two inches. A baffle is required at the inlet side of the box when the slope from the septic tank to the box exceeds 1/2 inch per foot or when siph,. n dosin.a is used. e. There shall be a minimum two inch clearance between the inverts of the ou'lets and the bottom of the box to prevent short-circuiting and reduce solids carry-over. f. Distribution boxes may be constructed in place or purchased prefabricated. When concrete is used to construct boxes, it shall have a minimum compressive strength of 2,500 psi at 28 day set. g. Prefabricated boxes may be constructed of concrete, fiberglass, or plastic. The boxes shall be installed in conformance with the manufacturer's instructions in addition to the requirements above. Absorption Field Systems. A. Site requirements. a. The minimum distances that absorption fields shall be separated from other facilities ore shown in the table provided. b. A minimum of four feet of useable soil shall exist above bedrock and groundwater with a minimum separation of two feet to the lowest part of any trench. c. Absorption fields shall not be built under driveways, parts of buildings or ur der above- ground swimming pools or other areas subject to heavy loading. Surface waters shall be diverted from the vicinity of the system. B. Design criteria. a. The required length of absorption trench is determined from the percolation test results and confirmed by the on site soil evaluation. The maximum trench width for design purposes shall be 24 inches. b. Adjacent trenches shall be separated by at least four feet of undisturbed soi. Individual trenches shall be constructed parallel to the ground contours with trench bottoms as near level as possible. They need not be perfectly straight but abrupt changes in direction shall be avoided. C. Materials. a. Perforated distributor pipe shall be used in the trenches. Solid (non -perforated) pipe shall be used between the distribution box and the trenches. Perforated pipe shall be made of rigid or corrugated plastic and be labeled as fully meeting ASTM standards for use in septic systems. Corrugated plastic pipe delivered in coils is not to be used unless provision is made to prevent the recoiling or movement of the pipe after installation. b. Aggregate shall mean washed gravel or crushed stone 3/4- 1 1/2 inches in diameter. Larger diameter material or finer substances and run -of -bank gravel are unacceptable. c. The aggregate shall be covered with a material that prevents soil from entering the aggregate after backfilling, yet must permit air and moisture to pass through. The preferred material for covering the aggregate is a permeable geotextile. Untreated building paper or a four inch layer of hay or straw is acceptable. Polyethylene and treated building paper are relatively impervious and shall not be used. D. Construction. a. Trench locations and depths should be marked by stakes before the trenches are excavated. b. The natural surface shall not be significantly disturbed. If the site is regraded or similarly disturbed, the soil shall be allowed to stabilize and new percolation tests conducted. c. The trench depth shall be as shallow as possible, but not less than 18 inches. At least six inches of aggregate is placed below the distribution line and two inches above tine line. d. The earth cover over the aggregate should not exceed 12 inches in order to enhance natural aeration and nitrogen uptake by plant life. Trenches shall be excavated tr design depth with bottoms practically level. Heavy equipment shall be kept away from the field because the weight may permanently alter soil characteristics due to compaction, cause trench cave-ins, and/or misalign and break pipe. e. Trench bottoms are to be raked and immediately covered with at least six inches of aggregate. Any smeared surfaces on the trench walls are to be raked. Distributor lines are carefully placed on the aggregate and covered with aggregate to a depth of at least two inches over the top of the pipe. Additional aggregate may be required to bring the top of the aggregate to within six to 12 inches of the surface. f. in gravity distribution systems, the pipe shall be carefully sloped at between 1/16 inch and 1/32 inch per foot. Grades shall be determined by an engineer's level, transit or carpenter's level. g. After the upper aggregate is placed, the geotextile, untreated building paper, hay or straw is to be immediately installed and the trench backfilled with native soil. If the trenches cannot be immediately backfilled, they should be temporarily covered with an impervious material such as treated building paper to prevent sidewall collapse and siltation into the aggregate. h. The earth backfill is to be mounded slightly above the original ground level to allow for settling and after settlement the entire area should be graded without the use oi` heavy equipment and seeded with grass. lwlqal�_ CONCRETE OR STONE MARKER ABOVE ALL BURRIED COVERS �- RECOMMENDED.

Heavy equipment shall be kept away from the field because the weight may permanently alter soil characteristics due to compaction, cause trench cave-ins, and/or misalign and break pipe. e. Trench bottoms are to be raked and immediately covered with at least six inches of aggregate. Any smeared surfaces on the trench walls are to be raked. Distributor lines are carefully placed on the aggregate and covered with aggregate to a depth of at least two inches over the top of the pipe. Additional aggregate may be required to bring the top of the aggregate to within six to 12 inches of the surface. f. in gravity distribution systems, the pipe shall be carefully sloped at between 1/16 inch and 1/32 inch per foot. Grades shall be determined by an engineer's level, transit or carpenter's level. g. After the upper aggregate is placed, the geotextile, untreated building paper, hay or straw is to be immediately installed and the trench backfilled with native soil. If the trenches cannot be immediately backfilled, they should be temporarily covered with an impervious material such as treated building paper to prevent sidewall collapse and siltation into the aggregate. h. The earth backfill is to be mounded slightly above the original ground level to allow for settling and after settlement the entire area should be graded without the use oi` heavy equipment and seeded with grass. lwlqal�_ CONCRETE OR STONE MARKER ABOVE ALL BURRIED COVERS �- RECOMMENDED.
