Wastewater is collected in the septic chamber where gross solids are separated.The waste stream is then aerated in the aeration chamber.Aerated effluent passes through the clarifier then into the pump chamber.The expected waste strength from the X02 will be 30 mg/I CBODS and 5 mg/I TSS. Effluent is dosed through a 120 mesh disc filter to OSCAR coils, installed in ASTM C-33 sand.

Round up the design flow to the next 500 gpd value. For instance, a 600 gpd design flow will need 2 aerators (600 gal. rounded up to 1000 gal. needs 2 aerators). The aerator box must be installed so that the bottom of the aerator box is at the same elevation or higher than the top of the tank risers, see Illustration 3. If the site is sloped the aerator box can be buried, upslope from the tanks. The sides of the aerator box lid must not be buried. Aerators can be installed up to several hundred feet away from the diffusors. The line between aerator and diffusors must slope toward diffusors. Aesthetic concerns should be considered when placing the aerator box.

There may be a desire to cover the OSCAR with something additional to the specified ASTM C-33 sand. The intent is not to have too much additional cover over the final C-33 sand layer that would prevent the sand from accessing oxygen from the atmosphere. Placing too much cover will inhibit plant root growth. Because the C-33 sand is sub-surface irrigated, grass and other ground cover will grow rapidly, forming a firm protective cover over the OSCAR. At the end of the first growing season the C-33 sand layer will be as firm as native soil to walk on. Options include: Landscaping jute mat with grass seed or ground cover plantings • A thin layer of mineral soil low in organic content (<10% organics) • Thin layer of crushed or washed rock for wind erosion protection. • Thin layer of bark to wood chips. • Aggregates the size Of rip-rap (5-6 inch diameter) can be "placed"on the OSCAR for protection from deer or elk traffic. These larger sized aggregates must be placed, not dropped, on the OSCAR to prevent breakage of piping and other materials. • Wire mess can be installed over the sand to prevent erosion and allow for grass to grow.

Installer responsible to contact designer prior to installation. 4. Installer responsible to submit installation form to designer with a plot map, tank information, pump information any changes made to the design within two weeks of final inspection by the Mason County Health Dept 5. Oscar drainfield: ASTIR C-33 sand media as per Washington Department of Health's Recommended Standards and Guidance for Intermittent Sand Filter. 6. Minimum of 6" of sand throughout out the lateral(coll) area, must be level. 7. Oscar X02 parts list on Page B. Controls to be set per X02 guidelines 9. Septic tank location must meet all required setbacks. 10. Keep wheeled vehicles off the drainfield area before, during and after installation. 11.Tracked equipment only 12. ,All ground, surface water and roof drains must be diverted away from the septic tanks and drainfield. 13. 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 14. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the drainfield 15. Exposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill from the drainfield. 16. Install access risers on all tanks, valve box and ends of laterals. 17. Make sure septic tank risers are epoxied or caulked to cast in riser rings on tank. 18. Lids must form a water and gas tight seal with the access risers. 19.This system must be installed by a Mason County Certified installer. 20. Deviation from this design without prior approval from the designer and Mason County Health Department will make this design null and void. 21. 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 desig w of one hundred twenty gallons per day. This creates a surge factor of 33% but a ' i ted flow is ninety gallons per bedroom per day. Q /t 6 �rydYtE. r N �; Li ED DESIGNER i i0 System Owner Responsibilities: 1.
