Onsite Wastewater Treatment System (OWTS) Installation Observations
6809 CR 214
Garfield County, Colorado
Permit Number SEPT-6096
David,
ALL SERVICE septic, LLC observed the installation of the onsite wastewater treatment system (OWTS)
on April 15 and 21, 2020 for the subject property. Jay Billington installed the system.
The existing septic tank serving the residence was abandoned by pumping and crushing the top, bottom,
and sides and filling the remaining void with on-site material. The STA was abandoned in place.
The new OWTS design was based on 6-bedrooms. An average daily wastewater flow of 675 GPD was
used.
The existing sewer line remained for the first 20-feet. A new SDR-35 sewer line with a double-sweep
clean out and minimum 2% grade to the septic tank was installed.
The system installation included a 2000-gallon, two-compartment concrete Valley Precast septic tank
with an effluent filter on the outlet tee. Risers bring the manhole lids to grade for access. An effluent
filter was installed on the outlet side of the septic tank with a handle extension. This filter must be
cleaned annually, or as needed.
Effluent gravity flows to a distribution box, and then to five gravelless chamber trenches. The distribution
box was accessible from grade and flow equalizers were installed on each outlet pipe in the distribution
box.
Each trench consists of 16 ‘Quick 4’ Standard Plus Infiltrator® 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 OWTS 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,
