OSCAR At-Grade Drip Distribution Systems EXPIRES t 1. Installers must attend OSCAR X02 training and be certified by Dave Lowe at Low Ridge Technologies(www.lowridgetech.com)prior to installing this system. 2. Installer must review OSCAR X02 installer manual prior to system installation. 3. OSCAR XO2 supply kits are available through LowRidge Technologies approved suppliers only. 4. The Treatment Tank and Discharge Tank must both be 2-compartment, State approved and sized per the OSCAR X02 manual and the onsite wastewater treatment system designer. 5. OSCAR Sand media must meet or exceed ASTM C-33 standards. 6. Install drainfield level with contour of the ground. 7. Install drainfield during dry weather and soil conditions;any soil smearing must be eliminated by hand raking. 8. Tanks must have risers to the surface as required by Mason County to ensure easy access for future operation and maintenance. 9. Headworks must be in boxes accessible from the surface for future operation and maintenance. 10. Ensure any trees and shrubs are removed,grass is cut short and then scarify surface of ground in drainfield area to prep for drainfield. 11. Ensure 6"minimum cover sand media over the drip irrigation tubing. 12. Install audio/visual high-water level alarm. Redundant off switch not required. 13. Flow inducer tube or block are not required for the pump, it can sit on bottom of tank. 14. Install return line from headworks back into the tee outside the inlet of the treatment tank. 15. Encase all water lines within 10' of drainfield and under any driveway/parking areas. 16. Divert all storm water runoff and house downspouts away from on-site sewage system. 17. No curtain drains allowed within 10' of the up-slope edge or 30' of the down-slope edge of the drainfield and reserve area. 18. Inspect floats, clean filters,and test high water level alarm every 6-12 months as needed. 19. All materials and workmanship must meet County and State regulations. 20. Deviation from this design without prior approval from the Designer and Mason County Environmental Health Department will make this design null and void. 21. All manhole lids and access, sampling or inspection ports must have locking covers and be located at ground level. 22. All transport lines under driveways or parking areas must be encased to prevent crushing. 23. The tanks are to be protected from vehicle traffic or traffic-rated tanks may be used. 24. The drainfield is to be protected from all vehicle traffic or other damaging factors that could compact or disturb the soils. 25. The preferable cover planting for subsurface drip is turf or grass, or non-invasive groundcover plants. It is recommended to install an optional jute mat upon completion of the drainfield to prevent erosion and then seed with grass immediately. Other options include a thin layer of mineral soil low in organic content(<10%organics)and grass,a thin layer of crushed or washed rock for wind erosion protection,or a thin layer of bark or wood chips. 26. Do not cover the drainfield with organic mix(manufactured topsoil from compost)or filter fabric. 27. The homeowner should ensure no vehicle traffic,roto-tilling or digging in the area of the drip field to prevent damage to the drip tubing. Also, invasive plant species should not be allowed. 28. Home/property owner is responsible for all property lines, corners, surveys,encroachments,etc. 29.
