It's the owner's responsibility to verify property lines, utility lines (water, sewer, power, phone and gas) prior to installation. 1. Water line may need to be rerouted if reserve drainfield area is used. 2. Location of failing drainfield not know. We dug three soil logs and did not encounter any existing laterals. 3. Concrete tanks required 4. First compartment of pump tank will be outfitted with FUJIMAC 80 II air pump 5. Gravel base drainfield required 6. Timer to be set at 270 GPD 7. Keep wheelea 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 Thurston County Certified installer. 16. Deviation from this design without prior approval from the designer and Thurston 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. I 19. Install trench bottoms level and always maintain a minimum of six in �-s i tie, native soil.. , aft 20. install threadeo clean outs at the ends of all laterals (caps must ;riches of finish tirade and be in a valve box as s n diagr- � ' ' 2,t 21. tnstau audio/visual alarm.
