System is 45 years old. System is not accepting any effluent 2. The prepared site plan is not a survey. It's the owner's responsibility to verify property lines, utility lines (water, sewer, power, phone and gas) prior to installation. 3. Only area for a repair drainrfield would be Lake Limerick easement 4. Low profile infiltrators required 5. Orifice orientation at 12:00 6. Extremely important not to exceed 180 GPD. 7. Keep wheeled vehicles off the drainfield area before, during and after installation. Tracked equipment only 8. 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. 9. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the drainfield 10. Exposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill from the drainfield. 11. Install access risers on the septic tanks, valve box and ends of laterals. 12. Make sure septic tank risers are epoxied or caulked to cast in riser rings on tank. 13. Lids must form a water and gas tight seal with the access risers. 14. Install effluent filter specified in this design at the septic tank outlet. 15. This system must be installed by a Mason County Certified installer. 16. Deviation from this design without prior approval from the designer and Mason County Health Department will make this design null and void. 17. 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 anticipated flow is ninety gallons per bedroom per day. 18. Install laterals with contour of the ground. 19. Install trench bottoms level and always maintain a minimum of six inches into native soil.. 20. Install threaded clean outs at the ends of all laterals (caps must extend to ithin six. inches of finish grade and be in a valve box as shown on diagram. 21. Install audio/visual alarm. 22. Filter fabric required over drain rock prior to backfilling. If the drain ro 'xte above the original grade, run the filter fabric at least©© ices down the tr Pvy ~' $$ iginal grade.
