Introduction:
The OSCAR-XO2 treatment system is comprised of two technologies: the X02(4
chambers: septic, aeration, clarifier, and pump chambers) and the OSCAR: drip tubing coils,
C-33 sand, reverse flush headworks, and control equiprnent.
waste Wastewater is collected in the septic chamber where gross solids are separated. The
stream
claifierthen into the pump dchamber The expect d waste stre in the erahn chamber Aeratength from effluent pthe XO.'aes will be 30 / 0
mg/I CBODS and 5 mg/I TSS. Effluent is dosed through a 120 mesh disc filter to OSCAR coils, w
installed in ASTM C-33 sand. Effluent discharged from the coils is treated by the sand prior
to infiltrating into the receiving soil. The treatment level in the final discharge is expected to
reach 2 mg/1 CBOD, 1 mg/I TSS, and 36 FC/100 ml, meeting Treatment Level A. The XO2 can
only be used with the OSCAR.
Design:
Single family residence packages are designated as: OSXO2-240, OSXO2-300,
OSX02-360, OSXO2-450, O5XO2-480, and OSX02-600 and have the corresponding
design flows of 240, 300, 360, 450, 480, and 600 gallons per day. The OSXO2-240 -
480 are standard packages. Design flows greater than 480 gallons per day are
considered custom and will require design assistance from Lowridge Onsite
Technologies, Inc. For the standard single family residence OSCAR-X02 package
parts list see the appendix. The XO2 can only be used with OSCAR coils. All tanks

day. The OSCAR has differentdesigned gallons
sizing criteria nthan the ftX02.uThe X0200is desiign der in
increments ranging from 500 to 3,500 gallons per day (for reference, see Table
1-2). The OSCAR is designed in increments of 62.5 or 125 gallons per coil per day,
depending on coil model (see Tables 2 and 3). Consequently, a design for a 7
bedroom system (840 gpd) could incorporate two 1750 gallon, two compartment
tanks plus an addition aerator (0Xz+1 kit) with 14 OS-50 OSCAR coils (875 gpd).
X02:
The tanks for the XO2 can be arranged in different formats. One option is to
use two double compartment tanks of the same size, either made of polyethylene
or concrete, with the following criteria:
Treatment The partition wall between the first and second
compartment of the treatment tank must have either a 4 inch by-pass hole or the
bottom of a tee baffle must extend down between 40% to 60% of the liquid depth
of the tank.
Dischar e Tank: The partition between the first and second compartment of
the discharge tank must have a 4 inch by-pass hole located at least 18 inches
above the floor of the tank or no more than 27 inches between the bottom of the
by-pass hole and floor of the tank. Recommended hight of by-pass hole is 18
inches.
To determine the tank size for design flows greater than 500 gpd, the tanks
can be up size proportionally. Example:
Tanks for a 500 gpd design = 1,000 gallons
A 7 bedroom design (120 gpd x 7) is 840 gpd. ���
Q- . 840 gpd/500 gpd = 1.68 or 68% increase
sP sr} o to k size for 840 gpd = 1,000 gal. x 1.68 = 1,680 gallons
��. � 1750 gallon, two compartment tank can be used.

For tanks with water ti ht structurall sound artitions: for both the
treatment tank and discharge tank a double compartment tank with tee baffles
can be used (no flow through ports). Rip the discharge tank around so the smaller
compartment is first as shown (see Illustration 2). The clarifier chamber is to
remain full.

As the al y design flow rates increase, larger tanks
needd, It may
become necessary to have individual tanks for each chamber�ll orbe a combination of
tanks to meet the volume requirements. For example:
3.000¢od design flow (refer to Table 1-2
Seotx chamber = 4000 gal, needed, use a 3000 gal, tank + 1000 gal. tank.
Aeration Chamber = 2-1000 gal. tanks.
Clarifier chamber = 2- 1000 gal. tanks.
Pun chamber = 3000 gal. tank + 1000 gal, tank.
In this example, the septic chambers could be connected using standard tee
baffles making a two compartment chamber. The aerator chamber could be
arranged the same as the septic chambers. Half of the diffusors would be placed in
each 1,000 aeration chamber. The clarifier chambers could either use tee baffles
or be connected together below the l'

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 wilt
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.
Do Not Cover C-33 Sand with:
• organic mix (manufactured top soil from compos
• filter fabric

Installation Notes
Oscar-X02 Treatment System
XXX HIDDEN COVE LANE 32424-22-00160
1. The on-site septic system has failed.
2. Stumps in the drainfield area must be cut down to ground level or below.
3. Installer and designer must meet on site prior to installation.
..r4c.4. Oscar drainfield: ASTM C-33 sand media as per Washington Department of
Health's Recommended Standards and Guidance for Intermittent Sand Filter.
5. Concrete two compartment tanks required for septic and pump (See illustration 1
and 2 on pages 6 and 8)
6. 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.
7. Minimum of 6" of sand throughout out the lateral area, must be level.
8. The tanks may be moved as necessary to accommodate building requirements.
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 fight 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 design flow of one hundred
twenty gallons per day. This creates a surge factor o 33% but anticipated flow is ninety
gallons per bedroom per day,
