Onsite Wastewater Treatment System (OWTS) Installation Observations
2074 CR 109
Garfield County, Colorado
Fran,
ALL SERVICE septic, LLC observed the installation of the onsite wastewater treatment system (OWTS)
on June 3 and October 27, 2014 for the subject property. Village Excavating installed the system.
The existing 1500-gallon, two-compartment septic tank remained in use and was in good condition. The
existing absorption area was abandoned in-place.
The installation included a new distribution box and four rows of 14 ARC ADS chambers for a total of 56
chambers and 691 square feet of infiltrative area (using 12.34 square feet per chamber). The chamber
bed was placed on 6-inches of ASTM C33 concrete sand.
During a site visit on October 27, 2014, measurements were taken from the house to the observation port
at the end of the field. The outline of the house on the site plan is inconsistent with the actual house
footprint. Dimensions on the record drawing and the representation of the house and deck footprint are
to the were documented during our site visit,, but are not a result of a survey. The septic tank lids and
distribution box were not accessible from grade; therefore, these components were not accurately
measured for the record drawing. We recommend bringing these components to grade for better
accessibility.
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:
