Onsite Wastewater Treatment System (OWTS) Installation Observations
6255 CR 109 (Wilson House)
Garfield County, Colorado
Permit Number SEPT-12-18-5586
Joe,
ALL SERVICE septic, LLC observed the installation of the onsite wastewater treatment system (OWTS)
on April 23, 2019 for the subject property. B&H Contractors and Top Gun Plumbing installed the system.
You have opted to keep the existing septic tank serving the cabin. The cabin had not been connected at
the time of our inspection. The existing septic tank serving the previous residence was abandoned.
New, 4-inch diameter SDR-35 sewer lines with double-sweep clean outs with a minimum 2% grade to the
septic tank were installed existing the new residence.
The system installation included a new 2000-gallon, two-compartment Valley Precast concrete septic
tank with an effluent filter on the outlet tee. This filter must be cleaned annually, or as needed.
Risers bring the manhole lids to grade for access.
Effluent gravity flows to a distribution box, and then to four gravelless chamber trenches. The distribution
box was accessible from grade and flow equalizers were installed on each outlet pipe in the distribution
box to assure equal flow to each bed.
Each trench consists of 16 ‘ARC 36’ chambers for a total of 960 square feet of infiltrative area. There
was at least 4-feet of undisturbed soil between each trench. Inspection ports were installed at the
beginning and end of each trench. Ports may be cut to grade and placed in sprinkler boxes for access.
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,
ALL SERVICE septic, LLC Reviewed By:
