Project No. 19-7-291.02
Subject: Certification of Onsite Wastewater Treatment System, Proposed Residence, Lot 1,
Sillivan Subdivision, 4703 County Road 335, Garfield County, Colorado
Dear John:
A representative of Kumar & Associates observed the installation of the Onsite Wastewater
Treatment System (OWTS) for the residence at the subject site as required by the Garfield
County Environmental Health Department. Our observations and recommendations are
presented in this report. The services are supplemental to Kumar & Associates agreement for
professional services to John Goss dated June 27, 2019.
We previously designed the OWTS for the residence as submitted in our report dated September
27, 2019, Project No. 19-7-291.02. The system was designed for three bedrooms. The OWTS
was installed by Miles Rippy Excavating.
We performed our as -built evaluations on December 5, 2019 and April 3, 2020. The OWTS
components observed included: sewer line, cleanout, septic tank, effluent line, automatic
distributing valve (ADV), control panel and soil treatment area (STA) and the locations of these
components. The installation and locations of the system components were verified as shown on
Figure 1. Pictures of the OWTS components made during the site visit are included with this
report. The trenches and Infiltrators reportedly were not backfilled until the snow melted. The
distance locations to the septic tank shown on Figure 1 were made by taping.
On April 3, 2020, after power had been supplied to the pump, a pump performance test was
performed with adequate pump pressure observed. A minor leak was noticed in an effluent line
between the ADV and the STA. The leak was reportedly caused by a stray perforation in the
pipe and was repaired on April 6, 2020 by Miles Rippy Excavating.
It is our opinion that the OWTS was installed in general conformance with the above referenced
design.

The observations and recommendations presented above are based on our site observations and
our experience in the area. We make no warranty either express or implied. Alterations to the
system or improper backfill and site grading could affect the operation and effectiveness of the
OWTS.
Please feel free to contact us if you have any questions regarding this letter.
Respectfully Submitted,
Kumar & Associates, Inc.
