Coils are arranged in laterals. Each lateral is a single coil or a group of coils
linked in series between the supply and flush manifolds. The OSCAR-11 coils are
timed dosed and flushed automatically.
The standard single family residence OSCAR-11 packages with design flows
between 240 to 600 gpd include a headworks (model HWN-.7-RF) for dosing the
OSCAR-11 coils. Table I depicts the number of OS-50 coils and laterals required for a
given design flow using an Lowridge Onsite Technologies 30 gpm, 1/2 hp, 110 volt
turbine pump, model LOT-30. Table 11 depicts the number of OS-100 coils and
laterals required for a given design flow using the same pump. The criteria in
these tables must be followed. If a deviation is required, contact Lowridge for
assistance.
The tables also indicate how much excess head, under the pump curve, is
available for supply line elevation lift and friction loss. All manifolds, supply and
flush lines are assumed to be 1" sch 40 PVC. The designer must calculate the total
dynamic head (TDH) for the OSCAR-11 supply line. Use the flow rate indicated
under the heading "Flush GPM" in Table I or II for the corresponding design flow
and coil model to calculate the friction loss of the supply line. If the calculated
TDH is greater than the "Excess TDH" value in Table I or II, call Lowridge for
assistance. TDH is calculated by adding the friction loss of the supply line to the
elevation lift from liquid level in pump tank to the OSCAR coils. Use the following
Hazen-Williams formula to calculate friction loss. Always use the Flush Flow Rate
valves when calculating fiction loss. 4q,�0'°-'

OSCAR-II Cover Options.
There may be a desire to cover the OSCAR with something additional to the
specified ASTM C-33 sand. 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-11 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. All reverse flush headworks incorporate
cold weather features.

Installation Notes
Oscar II Treatments System

1. 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.
2. This is a failure, surfacing sewage
3. Installer and designer must meet on site prior to installation.
4. Oscar drainfield: ASTM C-33 sand media as per Washington Department of Health's
Recommended Standards and Guidance for Intermittent Sand Filter.
5. Order II parts on page 8
6. Waterline and manifold crossing must be cased.
7. Minimum of 6" of sand throughout out the lateral area, must be level.
8. All tanks must be concrete.
9. The tanks may be moved as necessary to accommodate building requirements. Septic
tank location must meet all required setbacks.
10. Keep wheeled vehicles off the drainfield area before, during and after installation.
Tracked equipment only,
11. 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.
12. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the
drainfield
13. Exposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill from the
drainfield.
14. Install access risers on the septic tanks and control box.
15. Make sure septic tank risers are epoxied or caulked to cast in riser rings on tank.
16. Lids must form a water and gas tight seal with the access risers
17. This system must be installed by a Mason County Certified installer.
18. Deviation from this design without prior approval from the designer and Mason County
Health Department will make this design null and void.
19. This design was sized per Washington Administrative Code WAC246-272A-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 of 33% but anticipat w is ninety
gallons per bedroom per day.

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

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.
