Updated Date: 12/7/2015 522 Dow Creek Dr 42216-50-00049 This is a failure, appears drainfield has been driven on, not taking effluent. We dug one soil log in the middle of the bed, did not dig another one due to the bed only being 24' long. We used a sand augmented be allowing us to keep 100' from the shoreline. There is not enough room for a conforming system due to the fact that we do not have room for a reserve with out encroaching on the creek. 4 41 ,; St LP 10 18 .\? ts Leal CY WAITE z7 LICENSED DESIGNER APPROVED MAY 0 5 2025 MASON COUNTY ENVIRONMENTAL HEALTH RET 3 ld 4.7 i.001 l_ �J•O�pep��,p /1 SONCOUMAY n5 Z95 p �—�, /�v, �ER4RONAENT HEALTH Fr , 5 = N a N 0 20.0 �'.. rr` o ' 0 u, -- 0 OZS-- Ci f r al f r , At° VI )41 0 Q0F T 1 ` +�, r7�� 1CZf Sti .L Of Iii 95 418 /I I0�• T`♦ / 1 �♦ , O '♦♦ , ' LICENSED DESIGNER 1♦ ! , ccr♦ ' 1 Ev PRE S C5it9,~ r � �♦ ffily 0 11LIL gm.

The tanks may be moved as necessary to accommodate building requirements. Septic tank location must meet all required setbacks. 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.

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 locator tape on top of all drainfield laterals. 21.
