Onsite Wastewater Treatment System (OWTS) Installation Observations
11707 CR 245
Garfield County, Colorado
Permit Number SEPT-6804
Tad and Katie,
CBO Inc. observed the installation of the onsite wastewater treatment system (OWTS) on August 20,
2021 for the subject property. Silt Mesa Excavating installed the system.
The OWTS design is based on 4-bedrooms. An average daily wastewater flow of 525 GPD was used.
The minimum 100-foot setback from the well to the soil treatment area (STA) was verified.
The system installation included a 1500-gallon, two-compartment Roth® poly 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 with flow equalizers installed on each outlet pipe in the distribution box to
assure equal flow to each trench.
Each trench consists of 13 ‘Quick 4’ Standard Plus Infiltrator® chambers for a total of 52 chambers and
624 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. CBO Inc. 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 on the expertise of the installer, soil
type, and weather conditions.
Please call with questions.
Sincerely,
CBO Inc.

OWTS Permit #: SEPT-6804
August 24, 2021
Tad and Katherine,
On August 20, 2021, we visited the residence under construction at 11707 County Road
245 near New Castle in Garfield County, Colorado to observe the OWTS installation pursuant to
OWTS Permit # SEPT-6804. At the time of our site visit, the contractor had installed the new
sewer line, the new cleanout adjacent to the residence, a new 1,500-gallon two -compartment
septic tank, the new effluent line, the new distribution box, and the four chamber trenches. The
septic tank and distribution box were installed level, with access brought to grade. An effluent
filter was present in the outlet tee of the septic tank. The chamber trenches were level, and
consisted of 13 Quick4 chambers per trench, for 52 total chambers (624 ftz). Additionally,
inspection ports were present at each end of each trench. In our opinion, this system was
installed in general conformance with Garfield County OWTS Regulations. No further action or
review from Garfield County Environmental Health is required regarding this permit. Please
provide an As -Built drawing of the system, when available, for our files.
Thank you,
