NOTES 1871 E Johns Prairie Road Shelton, WA 98584 360-426-6697 Rob's Excavating has designed this system in accordance with all -current state and county Health Department requirements and assumes no responsibility for its use or longevity. The owner therefore agrees to maintain and make all necessary repairs to the system at no cost to Rob's Excavating. 2. The contractor shall be certified and approved by the county to install septic systems. 3. The contractor shall field verify all contours, stub out elevators, and trench depths in drainfield areas before construction. 1 construction materials and installation shall conform to all applicable state ;aunty Health Department requirements. be the installer's responsibility to have a copy of this design onsite at all uring construction, t shall be the owner's and/or installer's responsibility to notify Rob's vating and the county Health Department for the required inspections ore backfilling. 7. All required tests shall be successfully run before calling Rob's Excavating for final inspection. All components, including all tank access lids must be accessible for inspection, 8. Rob's Excavating and the County Health Department shall first approve any variations to this design. 9. Owner/Installer shall not remove any topsoil in drainfield area. Removal of topsoil could render the site unusable. 10, Existing utilities shown on the plans have been plotted from the best information available to the designer, Accuracy and completeness are not guaranteed. :: �v.

Install laterals with contour of the ground. 2. Install trench bottoms level and at all times a minimum of six inches into the native soil. 1 Install locator tape on top of all grainfield laterals. 4. Install observation ports as indicated on`the plot plan (minimum two per drainfield with bottom extending to the drain rock /.native soil interface). 5. Install drainfield during dry weather and soil conditions, and soil smearing must be eliminated by hand raking. 6. Install threaded clean -outs at the ends .of all laterals (cap must extend to within 6 inches of finished grade and be marked with locator tape). 7. Install audio/visual high water alarm. 8. Install 1/8 inch mesh non -corrosive pump screen (min. 12 -sq. ft. surface area, not to interfere with controls or floats). 9. Install check valve in pump outlet line to prevent system from draining back into the pump chamber. 10. Filter fabric required over drain rock pricsr to backfilling. If the drain rock extends above natural grade, run the filter fabric at least 2 inches down the trench wall. 11. Divert all storm water run-off away on-site sewage system. 12. No curtain drains allowed within 19 ft. jor the up-slope edge of the drainfield and reserve area. 13. No curtain drains allowed within 30 ft. of the down-slope edge of the drainfield and reserve area. 14. Have the septic tank and pump chamber pumped or inspected every three to five years. 15. Inspect floats, clean pump screen a id test water alarm every 6 — 12 months as needed. 16, All materials and workmanship must meet County and State regulations. 17. Septic tank risers to be at or above. finish grade, 18. Deviation from this design without prior approval from the Designer and Mason County Health Department will make this design null and void. 19. Pump chamber lid to be above finish grade. 20. The on-site septic system owner is responsible for properly operating and maintaining the OSS and shall: a) Determine the level of solids and scum in the septic tank once every three years. b) Employ an approved:pumper to remove the septage from the tank when the level of solid( and; Krum' indicates that removal is necessary. c) Protect the OSS area:aud,Ihe reserve area from: 1. • Cover by.str.0 y1'o ;orimipervious material 2. Surface drainage,;:},:.;; .. 3. Soil coi paction by,vehioular traffic or livestock 4. Damage by soil,removal and grade alteration d) Keep the flow of sewage% ,Aie OSS at or below the approved design both in quantity and waste' strength, 21, High strength waste will increase the depth of the biomat in a drainfield, causing a decreased flow through the biomat and possible ponding or flooding of the drainfield. High strength waste in a residence is usually related to the "lifestyle" or habits of the home, generally resulting from one or morn of the following: a) Excessive use of'a garbage disposal b) Consecutive loads of.1au1dry done all on one day c) Excessive bleach, or.'.detgcts.,th added whiteners d) Dishwashing; show; Yid laundering all at the same time e) Medications — nntibiptios..aan kill or impair the biological process in the septic tank. f) Leaky plumbing (hydraulic overloading)
