Combining Hydraulic Layout and Basal Area Requirements: ./6f
To combine the coil layout and the basal area, start with the coil layout.
Refer to Tables 4 or 5 for minimum shoulder lengths. Zero to 5 percent slopes
(0-5% slope) are considered flat for basal area calculations and set back
considerations. It may be advisable to place the coils on the up side of the basal
area when the slope is 2 % or more. On flat sites, the coils should be placed in the
center of the basal area. The coils will be arranged in a single line, although the
line can be curved to match site contours. Also, no emitter shall be placed within
6 inches of the C-33 sand media shoulder.
On sloping sites (>5 to 20% slope) the coils will be placed parallel to the
contour and one edge of the coils must be placed about 12 inches from the
upslope basal boundary. There must be at least 6 inches separation added between
the drip tubing in different 05-50 coils. With the OS-100 coils the spacing is
already included with the 85 inch (7.1 foot) area. Side slopes of the C-33 sand ��\v
media is at least a 1 to 1 slope. Add the minimum coil length to the side slopes to
determine the minimum basal area length. Divide the total basal area square
footage by the minimum basal length to calculate the basal area width. Two

44 Aerator:
For each 500 gpd design flow one aerator will be needed. 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.
Place the aerator away from house windows, doors, and areas where people tend
to congregate, such as patios areas and barbecues.

OSCAR Cover Options.
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. 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 protect'
• Thin Layer of bark to wood chips. A�
Do Not Cover C-33 Sand with: Y

Installation Notes
Oscar-XO2 Treatment system
70 N E Galley 12330-51-00014
1. This is a failure found by the Mason County Health Department. Underground stream
appears to be running through drainfield area picking up sewage.
2. The prepared site plan is not a suniey. It's the owner's responsibility to verify property
lines, utility lines (water, sewer, power, phone and gas) prior to installation.
3. 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: ASTM C33 sand media as per Washington Department of
Health's Recommended Standards and Guidance for Intermittent Sand Filter.
6. Existing septic tank may be used as treatment tank or discharge tank.
7. Existing tank must be retrofitted with risers
8. Minimum of 6" of sand throughout out the lateral(coil) area, must be level.
9. Oscar X02 parts list on Page 8
10. Septic tank location must meet all required setbacks.
11. Keep wheeled vehicles off the drainfield area before, during and after installation.
12.Tracked equipment only
13. ,AII ground, surface water and roof drains must be diverted away from the septic tanks
and drainfield.
14. 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
15. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the
drainfield
16. Exposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill from the
drainfield.
17. Instal; access risers on all tanks, valve box and ends of laterals.
18. Make sure septic tank risers are epoxied or caulked to cast in riser rings on tank.
19. Lids must form a water and gas tight seal with the access risers.
20. This system must be installed by a Mason County Certified installer.
21. Deviation from this design without prior approval from the designer and Mason County
Health Department will make this design null and void.
22. This design was sized per Washington Administrate odeWAC246-272A-0230. The
operating capacity is based on 45 gallons per day r pits with two persons per
bedroom. The minimum design flow per bedroo r d is the operating capacity of
ninety gallons multiplied by 1.33. This results i I design flow of one hundred
Atw ,yp',ons per day. This creates a surge t a i ipated Flow is ninety

needed.
4. System owners are responsible for having maintenance performed annually.
5. System owners are responsible for responding to septic issues in a timely manner.
6. System owners shall not at any time change or alter settings in the control box.
7. System owner agrees to read and abide by information regarding their system in the
