Onsite Wastewater Treatment System (OWTS) Installation Observations

Max,
ALL SERVICE septic, LLC observed the installation of the onsite wastewater treatment system (OWTS)
on April 9, 2109 for the subject property. Avalanche Excavation installed the system.
The new 4-inch diameter Schedule-40 sewer line was installed exiting the residence with a double-sweep
clean out and a minimum 2% grade to the septic tank.
The system installation included a 1250-gallon, two-compartment concrete Valley Precast septic tank
with a traffic rated lid and an Orenco® Biotube Effluent Filter on the outlet tee. This filter must be
cleaned annually, or as needed. Risers bring the manhole lids to grade for access. Cast iron manhole
lids were installed.
Effluent gravity flows to a distribution box, and then to two gravelless chamber beds. The distribution box
is accessible from grade and has flow equalizers installed on each outlet pipe in the distribution box to
assure equal flow to each bed.
Each bed consists of a level manifold and four rows of 8 ‘Quick 4’ Standard Plus Infiltrator® chambers for
a total of 64 chambers and 768 square feet of infiltrative area. Inspection ports were installed in all four
corners of the bed. Ports may be cut to grade and placed in sprinkler boxes for access.
It should be noted that an electrical conduit runs over the western chamber bed.
The OWTS was generally installed according to specifications. This observation is not a guarantee of
workmanship and/or parts and materials. ALL SERVICE septic, LLC should be notified if changes are
made to the OW TS in the future. Any additional OWTS construction must be according to the county
regulations.
LIMITS:
Observations are limited to components that are visible at the time of the inspection . The installer must
have documented and demonstrated knowledge of the requirements and regulations of the county in
which they are working. The quality of the installation is dependent of the expertise of the installer, soil
type, and weather conditions.
Please call with questions.
Sincerely,
