Options include: • landscaping jute mat with grass seed or ground cover plantings • a thin layer of mineral soil Low in organic content (<10% organics) Do Not Cover C-33 Sand with: • organic mix (manufactured top soil from compost) • filter fabric The intent is not to have too much additional cover over the final C-33 sand Layer. 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. On a standard mound system, where soil cover is required, the soil cap can dry out in the summer months requiring additional irrigation to maintain vegetative cover. Cold Weather Options. In colder climates (eastern Washington) it may be necessary to prevent freezing in the OSCAR-II headworks. This is especially true with vacation homes where the houses are vacant in the winter and all power is turned off. In these situations Lowridge recommends allowing the internal portion of the HWN-.7-RF headworks to drain between doses. Alt reverse flush headworks incorporate the cold weather features. 4 V h3YP JD �N' P J /7 Ail 5 418 t O CINDYE WAITEN IDENSED DESIGN 1ppR Installation Notes• �� oc �� ( Nuwater BNR500 to an Oscar Distribution -4Yy-Fti R�B3p13 32023-32-00140 7272 SE /Meq Al QIA 4,44, This is a failure, drainfield is filled with roots and deep into the original soil. We are installing a three conforming primary and reserve drainfield. 1. Installer and designer must meet on site prior to installation. 2. Oscar drainfield: ASTM C-33 sand media as per Washington Department of Health's Recommended Standards and Guidance for Intermittent Sand Filter. 3. Order NuWater-o kit that does not come with control panel, control panel comes with Oscar Kit to serve both the NuWater and the Oscar 4. 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. 5. Minimum of 6" of sand throughout out the lateral area, must be level. 6. All tanks must be concrete. 7. The tanks may be moved as necessary to accommodate building requirements. Septic tank location must meet all required setbacks. 8. Keep wheeled vehicles off the drainfield area before, during and after installation. Tracked equipment only, 9. 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. 10. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the drainfield 11. Exposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill from the drainfield. 12. Install access risers on the septic tanks and control box. 13. Make sure septic tank risers are epoxied or caulked to cast in riser rings on tank. 14. Lids must form a water and gas tight seal with the access risers 15. This system must be installed by a Mason County Certified installer. 16. Deviation from this design without prior approval from the designer and Mason 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 one hundred twenty gallons per day. This creates a surge factor of 33% but anticip ow is ninety gallons per bedroom per day. 40 p o88.Y .TR il 9f e � wA ' Df cINDYE WAITEE LICENSED DESIGNER LAI'IRtS DEG System Owner Responsibilities: 1. Operation and Maintenance is required by Washington State Department of Health and Mason County Health Department. 2. The septic tank and pump tank should be pumped every three to five years or as needed. 3. System owners are responsible for having maintenance performed annually. 4. System owners are responsible for responding to septic issues in a timely manner. 5. System owners shall not at any time change or alter settings in the control box. 6. System owners agree to read and abide by information regarding their system in the User Manual provided by Mason County Public Health. 7. Keep the flow of sewage at or below the approved design operating capacity. 8. Keep waste strength at residential waste strength parameters. 9. Spread loads of laundry through the week. 10. Do not use excessive bleach or detergents with added whiteners. 11. Do not shower, do laundry and dishwasher at the same time 12. Antibiotics can kill or impair the biological process in the septic tank. 13. Leaky plumbing can hydraulic overload your on-site septic system.
