Onsite Wastewater Treatment System (OWTS) Installation Observations
811 CR 313
Garfield County, Colorado
Permit Number SEPT-11-17-5003
Bob,
ALL SERVICE septic, LLC observed the installation of the onsite wastewater treatment system (OWTS)
on May 7 and 18, 2018 for the subject property. Ryan Erpestead installed the system.
The system installation included a 1500-gallon, two-compartment Valley Precast concrete septic tank
with an effluent filter installed on the outlet tee. This filter must be cleaned annually, or as needed.
Risers were used to bring the septic tank manhole lids to grade for access and monitoring. An ejector
pump was required in the basement of the residence to allow shallow installation of the septic tank. The
ejector pump was specified by the plumber and is not included in this design.
Effluent gravity flows from the septic tank to a distribution box, which was accessible from grade. The
STA consists of three rows of 17 ‘Quick 4’ Infiltrator® chambers, for a total of 51 chambers an d 612
square feet of infiltrative area. There was at least 6-feet of undistributed soil between each trench.
Inspection ports were placed at the beginning and end of each trench. The ports may be placed in
sprinkler boxes for access from grade.
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:
