RE: John Brusco Property(Parcel 422331-51-00057)Evaluation of Failure
Dear Inspector:
Attached is a replacement septic drainfield design for a property located at 1220 NE Collins Lake Dr,
Tahuya.There is an existing 3-bedroom manufactured home installed along with a NuWater pretreatment to
subsurface drip dminfield in 2020.
The drainfield sustained major damage when it was rototilled by the landscaper and had to be replaced in
early 2023. It turned out that the soil structure was too damaged and along with a chronic running toilet,the
area became saturated again.
The existing pre-trash tank,NuWater pretreatment tank,and 1,000-gallon pump tank will continue to be
utilized. The old drainfield is to be abandoned in place and a new shallow pressure trench drainfield is to be
installed up behind the house. The new drainfield consists of 600 s.f.of shallow pressure trench using an
application rate of 0.6. -
The system will also continue to use a control panel including timed dosing,a counter and elapse meter to
prevent overuse and facilitate ongoing operation and maintenance. This is a compliant repair with 12"+
vertical separation and Treatment Level B. The drainfield meets 100'+setback to surface water and wells
and we have also designated a full reserve drainfield area.
The property owner's contact information is as follows:

Using a Pump Curve
A pump curve helps you determine the best pump for your system.Pump curves slow the relatioruhip between flow and pressure(total dynamic
head ar'TDH'),providing a graphical representation of a pump's optimal performance range.Pumps perform best at their reaminal flow rate.These
graphs stow opOmal pump operation ranges with a solid line and show flow rates outside of these ranges with a dashed line.For the most accurate
pump specification,use Cheri PumpSelect'soWne.

1. Install Laterals with contour of the ground.
2. Install trench bottoms level.
3. Install locator tape or rebar at each end of all drainfield laterals.
4. Install observation ports as indicated on the plot plan. One required at distal end of each
lateral in drainfield with bottom extending to the drainrock/native soil interface. Glue
"T'to bottom so Observation Port cannot be easily removed from ground. Install
removable cap on top of port at final grade level.
5. Install drainfield during dry weather and soil conditions;any soil smearing must be
eliminated by hand raking.
6. Install threaded clean-outs at the end of all laterals(cap must extend to within six inches
of finished grade and be marked with locator tape or rebar).
7. Install audio/visual high water level alarm. Redundant off switch not required.
8. Install check valve in pump outlet line to prevent system from draining back into the
pump chamber.
9. Tee to Tee construction between laterals and manifold with orifices oriented at 6 o'clock.
Install laterals to the manifold with the orifices at 12 o'clock, (do not glue), after pressure
test and Environmental Health Dept. approval,turn orifices down(6 o'clock) and glue
laterals to manifold. Orifice shields may be used with orifices in the 12 o'clock position
in lieu of turning the orifices down to the 6 o'clock position.
10. Filter fabric required over drain rock prior to back filling. If the drain rock extends above
natural grade,run the filter fabric at least 2 inches down the trench wall.
11. Encase all water lines within 10' of drainfield and under any driveway/parking areas.
12. Divert all storm water runoff away from on-site sewage system.
13.No curtain drains allowed within 10' of the up-slope edge or 30' of the down-slope edge
of the drainfield and reserve area.
14.No vehicular traffic over drainfield area.
15.Inspect floats, clean filters,and test high water level alarm every 6-12 months as needed.
16.All materials and workmanship must meet County and State regulations.
17. Deviation from this design without prior approval from the Designer and Mason County
Environmental Health Department will make this design null and void.
18.All manhole lids and access, sampling or inspection ports must have locking covers and
be located at ground level.
19.All pressure systems with a pump chamber outlet higher than the drainfield must have an
