RE: Rodney Peters Property (Parcel #32026-75-90061) Septic Upgrade
Dear Inspector:
Attached is a repair/upgrade septic design for a property located at 11 SE Jainee Ln, Shelton, WA 98584. The
existing septic was installed in 1994. The 2-bedroom septic consists of a 1,200-gallon 2-compartment septic
tank, a 400-gallon pump chamber,a 10' x 25' sand filter and a 22' x 83' mound drainfield.
At a recent service, it was discovered that the sand filter is clogged and had been overflowing. The pump in the
sand filter basin is operational and the mound drainfield is functioning. A previous permit SWG2022-00353 was
approved for the rebuilding of the existing 10' x 25' sand filter. That permit has since expired.
A new owner has purchased the property and since the septic needs repaired,they would like to go ahead and
upgrade the septic to 3-bedrooms since that is the actual size of the house and what the assessor has on record.
To upgrade to a compliant 3-bedroom septic,the following is required:
• Abandon/decommission the existing sand filter.
• Abandon/decommission the existing mound drainfield.
• Ensuring the existing tanks have risers and lids to the surface.
• Add an OSCAR X02 kit to the existing 1,200-gallon 2-compartment septic tank.
• Add a new OSCAR XO2 control panel. The existing panel may be used on-demand for the lift pump.
• Add a new 1,000 gallon minimum 2-compartment dosing/pump chamber with headworks.
• Add a new 10' x 45' low-profile OSCAR mound drainfield.
There are no wells within 100 feet of the drainfield and we have also designated a full reserve drainfield area.
The property owner's contact information is as follows:

Minimum side slopes at 1 : 1 slope @ 6" (2 x 6" = 1')= 1'
Minimum basal area length =coil length+shoulder widths+side slopes=37.5'+ 1'+1'=39.5' ...use 45'
Basal area width= required basal area a minimum basal length =450 sq.ft. =45'= 10'
Basal area dimensions=45'x 10'(450 s.f.)
Media:
OSCAR drainfield: ASTM C-33 sand media: as per Washington Department of Health's Recommended
Standards and Guidance for Intermittent Sand Filters.
Supplies/Control Panel:
• OSCAR XO2 Control Panel: The LF1P-RF-AR or ARA control panel shall be used to operate the
timed dosing sequencing of the OSCAR-XO2. Timer settings for the OSCAR-X02 are short and
very frequent(3 minutes off and 30 seconds on). The supply line needs to drain between doses,
so the "on time" may need to be increased to compensate for filling the supply line prior to each
dose.
Each OSCAR-XO2 unit will include: $yt�(\�

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.
Cover Options include:
• Landscaping jute mat with grass seed or ground cover plantings
• 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 or wood chips
Do Not Cover C-33 Sand drainfield with:
• Organic mix(manufactured top soil from compost)
• Filter fabric

Introduction:
The OSCAR-X02 treatment system is comprised of two systems: the X021a septic
chamber, aeration chamber, clarifier, and pump chamber) and the OSCAR: coils, C-33 sand,
reverse flush headworks, and control equipment.
Wastewater-is collected in the septic chamber where gross solids are separated.The
waste stream is aerated in the aeration chambers.Aerated effluent passes though the
clarifier then into the pump chamber. The expected waste strength 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. Effluent discharged from the coils is treated by the sand prior to infiltrating
into the receiving soil. Final discharge is expected to reach 2 mg/I CBOD, 1 mg/I TSS, and 36
FC/100 ml of effluent, meeting Treatment Level A. The X02 tanks can only be used with
OSCAR coils.

Design:
The single family residence packages are designated as: OSX02-240,
0SX02-300, 05X02-360, 05X02-450, 05X02-480, and OSX02-600 and have the
corresponding design flows of 240, 300, 360, 450, 480, and 600 gallons per day.
The OSX02-240, 300, 360, 450, and 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 X02 can only be
used with OSCAR coils. All tanks must be approved by Washington Department
of Health.
An OSCAR-X02 is two technologies combined together as one. The system
can be designed in increments of flow up to 3500 gallons per day. The OSCAR has
different sizing criteria than the X02. The X02 is designed in increments ranging
from 500, 750, 1125, 2250, 3,000, to 3,500 gallons per day (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) would incorporate a 1125 gallon per day X02 plus 14 05-50 OSCAR coils
(875 gpd).
X02:
Treatment Tank: The partition wall between the first and second
compartment of the treatment tank must have a 4 inch by-pass hole or the bottom
of the tee baffle located between 40% to 60% of the liquid depth.
Discharge Tank: The patrician 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 and no more than 27 inches between the bottom of the
by-pass hole and floor of the tank. Recommended hight is 18 inches, if possible.

1. Installers must attend OSCAR X02 training and be certified by Dave Lowe at Low Ridge
Technologies(www.lowridgetech.com) prior to installing this system.
2. Installer must review OSCAR X02 installer manual prior to system installation.
3. OSCAR X02 supply kits are available through LowRidee Technologies approved suppliers only.
4. The Treatment Tank and Discharge Tank must both be 2-compartment, State approved and sued
per the OSCAR X02 manual and the onsite wastewater treatment system designer.
5. OSCAR Sand media must meet or exceed ASTM C-33 standards.
6. Install drainfield level with contour of the ground.
7. Install drainfield during dry weather and soil conditions; any soil smearing must be eliminated by
hand raking.
8. Tanks must have risers to the surface as required by Mason County to ensure easy access for
future operation and maintenance.
9. Headworks must be in boxes accessible from the surface for future operation and maintenance.
10. Ensure any trees and shrubs are removed,grass is cut short and then scarify surface of ground in
drainfield area to prep for drainfield.
11. Ensure 6"minimum cover sand media over the drip irrigation tubing.
12. Install audio/visual high-water level alarm. Redundant off switch not required.
13. Flow inducer tube or block are not required for the pump, it can sit on bottom of tank.
14. Install return line from headworks back into the tee outside the inlet of the treatment tank.
15. Encase all water lines within 10' of drainfield and under any driveway/parking areas.
16. Divert all storm water runoff and house downspouts away from on-site sewage system.
17. No curtain drains allowed within 10' of the up-slope edge or 30' of the down-slope edge of the
drainfield and reserve area.

plants. It is recommended to install an optional jute mat upon completion of the drainfield to
prevent erosion and then seed with grass immediately. Other options include a thin layer of
mineral soil low in organic content(<10%organics)and grass, a thin layer of crushed or washed
rock for wind erosion protection, or a thin layer of bark or wood chips.
26. Do not cover the drainfield with organic mix(manufactured topsoil from compost)or filter fabric.
27. The homeowner should ensure no vehicle traffic, roto-tilling or digging in the area of die drip
field to prevent damage to the drip tubing. Also, invasive plant species should not be allowed.
