Onsite Wastewater Treatment System (OWTS ) I nstal lation Observations
143 North Meadow Drive
Garfield County, Colorado
Permit N umber SEPT -12-17-5050
Mike,
ALL SERVICE septic, LLC observed the installation of the onsite wastewater treatment system (OWTS)
on May 4,2018 for the subject property. Frontier Paving installed the system.
A 3-bedroom, single-family residence presently exists and is currently served by an existing OWTS.
Garfield County lndividual Sewage Disposal System Permit 4098 documents this system. The permit
received final approval from Garfield County on December 13, 2005. The existing system was not
addressed in this design. The new OWTS was designed to accommodate the addition of 2 bedrooms to
the existing residence. The laundry room will also be served by the new OWTS.
The sewer line exiting the residence has a double-sweep clean out and a minimum 2o/o grade to the
septic tank.
The system installation included a 1OO0-gallon, two-compartment Forterra 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. lf more than one riser is added to the septic tank, an extension handle
must be installed on the effluent filter.
Effluent gravity flows to a distribution box, and then to four gravelless chamber trenches. The distribution
box is accessible from grade and speed levelers were being installed on each outlet pipe in the
distribution box to assure equal flow to each trench.
Each trench consists of 15'Quick 4' Standard lnfiltrator@ chambers for a total of 720 square feet of
infiltrative area. There was at least 6-feet of undisturbed soil between each trench. lnspection ports
were installed at the beginning and end of each trench. Ports have been 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,
ALL SERVICE septic, LLC
