We are therefore applying for a permit to construct a septic system to serve the house. The Site Plan shows the location of the new system along with the alternate system. It also shows the location of the proposed water service line. 'l'he lot is currently served by the Municipal water system. The testholes placed on the lot revealed silty sands which percolated at rates ranging from 2 to 8 minutes per inch. No groundwater was encountered nor was any noted during the monitoring period. We have therefore designed a deep absorption trench system with an 9' effective depth and 53' in length. The distribution pipe will be placed at 3' below the surface and the total depth of the system will be 12'. A minimum of 3' of cover will be provided over the trench. The ground surface on the lot slopes in all directions from the home site as shown on the Site Plan. At the back of the lot the slope is approximately 10% in the area of the new absorption trench. The trench will be constructed parallel to the slope in accordance with Municipal requirements. Since the subdivision is served by the Municipal water system no conflicts will exist between the septic system and other wells in the area. Similarly, the septic system will not conflict with other septic systems on adjacent lots. If the system is constructed in accordance with our design the following statements apply: ]. The system, if constructed as designed, will have no adverse impact on the wells in the area or those to be constructed in the future. 2. 'The system, if constructed as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. 3. ']'he system, if constructed as designed, will have no adverse impact on reserved space, either surface or subsurface, on any lots located in the area. Lot 8, Block 1, Sky Hills Subdivision August 10, 1999 Page Two The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, Michael E:. Anderson, P.E.

WASTEWATER DISPOSAL SYSTEM CONSTRUCTION AND MATERIAL SPECIFICATIONS SUBJECT: LOT 8, BLOCK 1, SKY HILLS SUBDIVISION GENERAL: The scope of this project includes the procurement and placement of a new 1,500 gallon septic tank. It also includes the construction of a new 53' long x 3' wide x 9' effective depth absorption trench at the location shown on the attached Site Plan. The total depth of the trench will be 12' below existing ground. Mounding over the trench may be required to provide a minimum of 3' of protective cover. Construction shall be in accordance with the approved site plan, design drawings, Municipal Permit with any special provisions or conditions, and all applicable State and Municipal Wastewater Disposal Regulations. The Contractor shall be responsible for obtaining all underground utility locates and for the layout of the septic system and verification of the location of all lot lines. Unless specifically agreed otherwise, the contractor shall be responsible for final grading areas subsequently depressed from soil settling. Property owner shall be responsible for revegetation of affected areas unless specifically agreed otherwise. Contractors installing wastewater disposal systems must be certified by the Municipal Department of Health and Human Services for system installations. Owners installing their own systems must receive prior approval from D.H.H.S. before beginning system installation. SEPTIC TANK INSTALL.ATION 1. The 1,500 gallon septic tank must be procured from an approved source and installed at the location shown on the plans. A septic tank is to be constructed by a certified septic tank manufacturer. Construction shall include two 4" cleanouts for pumping access. 3. The septic tank shall be sufficiently bedded to prevent settling or shifting of the tank. 4. All standpipes on the septic tank shall extend a minimum of 12 inches above final grade. 5. Tanks installed without 4' of cover shall have a rninimum of 2" of direct burial insulation. A foundation cleanout shall be installed one to four feet from the building foundation. Two cleanouts are required between the tank and the drainfield. Lot 8, Block 1, Sky Hills Subdivision August 10, 1999 Page 2 of 3 7. Final grading over the tank shall be such that a positive slope exists away from the septic tank. DRAINFIELD CONSTRUCTION: The drainfield shall be constructed to the dimensions shown on the design. The bottom of the trench shall be within 2" of level. Distribution piping must be placed level with perforations down atop a level bed of drainfield rock. Rock should then be placed over the pipe to provide a minimum of 2" of cover. A silt barrier or geotextile fabric must be placed between the drainfield rock and the natural soil backfill. 4. Monitor tubes must be 4" in diameter and installed at the locations shown on the design. The portion below ground must be perforated.
