It's the owner's responsibility to verify property lines, utility lines (water, sewer, power, phone and gas) prior to installation. 2. SWG2004-00250 was approved with a waiver. There were two soil logs dug in the area. We dug one, did not want to disturb more soil. At this permit time,a waiver was approed to locate drainield 78' from the shoreline. 3. Existing septic tank required to be pumped and decommissioned. 4. Pump controls to be set at time of installation 135 GPD 5. Install system during dry weather with acceptable soil conditions 6. Gravel based drainfield required. 7. Clean C-33 or coarse sand to be used. 8. Septic and pump tank must be traffic rated. 9. Water line may need to be rerouted. 10. Transport line needs to be cased in the driveway. 11. Keep wheeled vehicles off the drainfield area before, during and after installation. Tracked equipment only, 12. All ground, surface water and roof drains must be diverted away from the septic tanks and drainfield. Ensure the final grade slopes away from these areas and water doesn't collect on or around them. Use swales, berms, catch basin and tight lines, curtain drains, etc. to divert all waters. 13. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the drainfield 14. Exposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill from the drainfield. 15. Install access risers on the septic tanks, valve box and ends of laterals. 16. Make sure septic tank risers are epoxied or caulked to cast in riser rings on tank. 17. Lids must form a water and gas tight seal with the access risers 18. Install effluent filter specified in this design at the septic tank outlet. 19. This system must be installed by a Mason County Certified installer. 20. Deviation from this design without prior approval from the designer and Mason County Health Department will make this design null and void. 21. This design was sized per Washington Administrative CodeWAC246-272A-0230. The operating capacity is based on 45 gallons per day per capita with two persons per bedroom. The minimum design flow per bedroom per day is the operating capacity of ninety gallons multiplied by 1.33. This results in a minimum design flow of one hundred twenty gallons per day. This creates a surge factor of 33% but anticipat flow is ninety gallons per bedroom per day. 22. Install laterals with contour of the ground 23. Install trench bottoms level and always maintain a minimum of six i s i # ative soil 24. Install locator tape on top of all drainfield laterals. � oa 25. Install threaded clean outs at the ends of all laterals (caps must `�`(_ �t�y�t ix inches of finish grade and be in a valve box as shown on dia ;), . �' '` tPA_ ( l , I 5t004 p C IND D DESIGN •1, 26. Install audio/visual alarm 27. Filter fabric required over drain rock prior to backfilling.
