#1 —Soil logs have been dug on this site and are the responsibility of the property owner or owner's agenl`&
have these soil logs buried after the inspection process has been completed.
#2—If during the construction process, soil conditions are found that may lead to premature failure of the
system,construction shall stop immediately and the designer shall be notified. Such soil conditions may
include but not limited to ground water, surface water,fill material, clay soil,bedrock,or excessively
permeable gravels.
#3 —Any substitutions or deviations from these plans shall be approved by the Health Department or the
designer prior to construction. All changes of the system components shall be documented by the designer
on the final As-built drawing.
#4—Peak design flow is_360_g.p.d., Recommended daily flow should not exceed_288_g.p.d.
or premature failure may occur.
#5—Backfill sewage disposal system immediately after final inspection process,cover soils should be
loamy sand or better. Seed final cover with grass or shallow rooting ground cover.
#6—Keep all maintenance access lids and ports accessible to ground surface.
#7—Installer should rake the finished grade smooth and slope it to divert all surface water runoff away from
tank and drainfield areas.
#8—Setbacks from house foundation to drainfields and reserve areas are 10', septic tanks 5' and transport
lines 2' unless otherwise stated within the design.
#9—Driveways and parking areas must stay 5' from drainfield areas. Tanks may be located within parking
area and driveways if approved for this application.
#10—Sewage waste strength should meet the following criteria or be lower Bod-5 = 130-174 mgll,TSS=
47-71 mgfl FOG= 10-20 mg4 PH=6.5-7.2 with microscopic life forms present.
#11 —Installer must adhere to all manufacturer installation requirements for all products used.
#12—The attached septic design does not represent a survey nor does it purport to show all easements or
encroachments,if any. Designer recommends property lines be located prior to any final installation occurs.
Surveys may be required to accomplish this.
#13—Property lines and comers have been represented by owner or owner's agent,the designer is not
responsible for errors due to inaccurate measurements from property lines or comers that are inaccurate.
#14—If a curtain drain is required with this design it must meet all Health Department installation
requirements.
#15—Developers,homeowners and installers,installations of on-site sewage disposal system should always
be installed in dry weather conditions. Irreparable soil damage may occur if systems are installed in wet
conditions. Planning the installation of system is very important and should be done as early in the building
development stage as possible. Wet weather conditions have caused delays in final approval dates.
#16—Maintenance is required will all sewage disposal systems. Owners will receive details of this in the
designer manual with the final approval of the application.
#17—Adhere to all designer notes located on design layout page.
#18—If development exceeds 10,000 square feet of impervious surface an engineered drainage plan may
need to be submitted. Options are available to reduce square footage requirements,such as wagon wheel
driveways, contact DCD for further details. Owners are responsible for any fee for redesigns or revisions
that may be needed after BSA submittal not due to designer error.
#19—Low flow water fixtures are recommended within the home to help lower the hydraulic load to the
system.
#20—Watertight components are a must for all onsite sewage systems. Installers are required to ensure all
components are watertight,extreme care should be used during backfilling of these components to prevent
settling and or water intrusion issues. If leaking components are not fixed in a timely manner,the designers
warranty may be void.
#21 —Installation of this design must meet all Health Department regulations and all adopted policies by the
Health Department that may apply. Installer is required to be versed in these regulations,if any questions
contact designer.
#22—All components used must be on State Department of Health approved products list for use with
residential waste.
#23 —Installer must inspect all tanks used at time of delivery and any tanks with defects must be rejected
and not used. When using any existing tank,the installer must due a 24 hour leak test to ensure all tanks
used are watertight.
#24—All plumbing must be routed into the new sewage system that has been designed. It is the property
owners responsibility to show the designer all plumbing stub outs and all gray and black water discharge
points. A plumber may be needed on old homes to ensure that all stub out locations are connected to the
new proposed sewage disposal system. An inside pump basin may be needed in some cases where
plumbing is located in basements and elevations for a gravity discharge cannot be maintained.
#25—Do not use low profile chambers or the system will be red tagged. All lateral lines must be a
minimum of 6"off the infiltrative surface. Lateral ends must be secured at the cleanout and must be in the
center of the port.
#26—Gravel trenches are recommended,but Arc 36"chambers are allowed.
Specific Designer Notes:
#1-This application is for a repair on an existing 3-bedroom home.
#2-A new gravity system is proposed with a 10'x45'gmviy bed of drainfield.
#3-Existing septic tank to be certified or must be pumped,decommissioned and replaced.
#4-Any large stumps holes to be filled with sand filter sand.
#5-Extreme caution must be taken on clearing drainfield area.Native soils can't be damaged
Recommended to be done by septic installer. A

Site Address of OSS Failure: 411 NE Barbara Blvd Belfair, 98528
Designer: Dave Ghylin / Dave's Septic Services Inc. Date of Investigation: 5/31/24
The OSS at the above address has failed due to:
❑ Hydraulic Overload (e.g., OSS flooded out due to leaking OSS components,
excessive groundwater, or surface water intrusion, leaky household fixtures, or water
use above the what the OSS was designed to handle, etc.)
❑Abnormal Waste Strength /Water Characteristics (e.g., normal OSS operation
appears to have been adversely impacted by household use of pharmaceuticals,
disinfectants, fats/oil/grease, or additives, etc.)
❑ Physical Damage (e.g., OSS was damaged due to vehicular traffic, new construction,
or animal intrusion, etc.)
❑✓ Age or Other(e.g., OSS does not exhibit any signs of the above. However, failed
due to age, system type, or site condition, etc.) Root intrusion.
