The original 1958 system has failed. It was installed in 1958 with a permit using a 500 gallon tank and a drainfield 20' from the lake. We are installing a pump basin with a solid pump that will pump up to a 1200 gallon concrete tank and gravity into proposed drainfield. 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. Existing septic tank must be properly decommissioned. 4. Install system during dry weather with acceptable soil conditions 5. Keep wheeled vehicles off the drainfield area before, during and after installation. Tracked equipment only, 6. 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. 7. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the drainfield 8. Exposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill from the drainfield. 9. Install access risers on the septic tank, D-box and observation ports. 10. Make sure septic tank risers are epoxied or caulked to cast in riser rings on tank. 11. Lids must form a water and gas tight seal with the access risers 12. Install effluent filter at the septic tank outlet. 13. This system must be installed by a Mason County Certified Installer. 14. Deviation from this design without prior approval from the designer and Mason County Health Department will make this design null and void. 15. 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. 16. Install laterals or bed with contour of the ground 17. Install trench bottoms level and always maintain a minimum of six inches into native soil 18. Filter fabric required over drain rock prior to backfilling. If the drai _ ock extends above the original grade, run the filter fabric at least 2 inches down th e'f 1 h wall. ts re APPRoa =�� Q, ,1 �`�Z�a V .

Operation and Maintenance is required by Washington State Department of Health and Mason County Health Department. 2. The septic tank should be pumped every three to five years or as needed. 3. System owners are responsible for having maintenance performed every three years as per WAC246-272A. 4. System owners are responsible for responding to septic issues in a timely manner. 5. System owner agrees to read and abide by information regarding their system in the User Manual provided by Mason County Public Health. 6. Keep the flow of sewage at or below the approved design operating capacity. 7. Keep waste strength at residential waste strength parameters. 8. Spread loads of laundry through the week. 9. Do not use excessive bleach or detergents with added whiteners. 10. Do not shower, do laundry and dishwasher at the same time 11. Antibiotics can kill or impair the biological process in the septic tank. 12. Leaky plumbing can hydraulic overload your on-site septic system. 441 0,1s„ v� ROV AP P510041 s �3 MAR 2 7 2°23 c7 CI DY W TE ` ` \ �. LICE DESIGNS � -1r , • hxniRLs Usla MASON C �,lA
