Vuecrest Dr. Union, WA 98592 December 15, 2025 (revised) Mason County Department of Health Services 415 N 6th St Shelton, WA 98584 RE: Timberlake Community Club Office— Parcel#22018-50-00152 Dear Inspector: The Timberlake Community Club plans to build an office building at their property located at XX E Lakeshore Dr W., Shelton. WA. There is an existing septic system onsite from 1975. The location interferes with the new proposed site development, so the old tank is to be decommissioned or removed and the old drainfield is to be abandoned. Daily Design Flow is conservatively calculated at 240 GPD maximum after the initial building and future expansion are built(see flow calculations below). The proposed septic components will consist of a 500- gallon pre-trash tank, a NuWater BNR-500 pretreatment tank, a 1,000 gallon pump chamber and (3) 3' x 33.5' (300 s.f.) of shallow pressure trench drainfield (using a 0.8 ap rate from Column B of Table VIII with TL C & BL3 or higher). The reserve drainfield has been sized with Column A of Table VIII with 400 s.f.. A timer, elapse time meter and event counter are required to ensure proper drainfield dosing and to accommodate future operation and maintenance. A curtain drain is proposed up-slope of the drainfield to ensure it does not get sheet runoff from the parking area and it is protected from groundwater. Usage of the proposed buildings is to be general office and meeting space. Waste strength is anticipated to be similar to residential usage with the main anticipated activities being employee restroom use, hand washing, lunch dish rinsing, etc. No chemicals or industrial products are to be put down the drains or into the septic system. The buildings will not have any floor drains or floor sinks and waste strength is expected to be similar to residential so an explosion proof pump or controls should not be required. Sizing Calculations: 4-5 current employees 6 future employees 11 maximum employees x 13 gpd = 143 gpd Occasional 25 person meeting max occupancy x 3 gpd = 75 gpd Total maximum usage = 143+ 75 = 218 gpd, rounded up to 240 gpd, equivalent to a 2-BR sizing This is a conservative sizing as meetings are occasional, and employees work 5 days per week If you need further information, please contact my office at(360) 898-2255.

EXPIRES 2. Install trench bottoms level. 11..-(a 3. Install locator tape or rebar at each end of all drainfield laterals. 4. Install observation ports as indicated on the plot plan. One required at distal end of each lateral in drainfield with bottom extending to the drainrock/native soil interface. Glue "T"to bottom so Observation Port cannot be easily removed from ground. Install removable cap on top of port at final grade level. 5. Install drainfield during dry weather and soil conditions; any soil smearing must be eliminated by hand raking. 6. Install threaded clean-outs at the end of all laterals (cap must extend to within six inches of finished grade and be marked with locator tape or rebar). 7. Install audio/visual high water level alarm. Redundant off switch not required. 8. Install check valve in pump outlet line to prevent system from draining back into the pump chamber. 9. Tee to Tee construction between laterals and manifold with orifices oriented at 6 o'clock. Install laterals to the manifold with the orifices at 12 o'clock, (do not glue), after pressure test and Environmental Health Dept. approval,turn orifices down (6 o'clock) and glue laterals to manifold. Orifice shields may be used with orifices in the 12 o'clock position in lieu of turning the orifices down to the 6 o'clock position. 10. Filter fabric required over drain rock prior to back filling. If the drain rock extends above natural grade, run the filter fabric at least 2 inches down the trench wall. 11. Waterlines must be a minimum of 10' to any tank or drainfield(a reduction to 5' may be obtained with a State waiver on lots that meet minimum lot size). Encase all water lines within 10' of septic transport lines and under any driveway/parking areas. 12. Divert all storm water runoff away from on-site sewage system. 13.No curtain drains allowed within 10' of the up-slope edge or 30' of the down-slope edge of the drainfield and reserve area. 14. No vehicular traffic over drainfield area or tanks. 15. Inspect floats, clean filters, and test high water level alarm every 6-12 months as needed. 16. All materials and workmanship must meet County and State regulations. 17. Deviation from this design without prior approval from the Designer and Mason County Environmental Health Department will make this design null and void. 18. All manhole lids and access, sampling or inspection ports must have locking covers and be located at ground level. 19. All pressure systems with a pump chamber outlet higher than the drainfield must have an anti-siphon valve or a 1/8"hole drilled in the discharge pipe above the pump to prevent siphoning. Ensure anti-siphon hole sprays down/away from tank opening. 20. All transport lines under driveways or parking areas must be encased to prevent crushing. 21. Homeowner is responsible for all property lines and easements. 22. Please Note: When you begin using your septic system, contact your septic installer to discuss setting up a schedule for your required Operation&Maintenance on your NuWater pretreatment system.
