Project No. 20-7-744.02
Subject: Certification of Onsite Wastewater Treatment System, Proposed Residence,
Lot 17-A, Mineota Estates, 926 Seneca Drive, Garfield County, Colorado
Dear Sigi:
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 you dated December 2, 2020.
We previously designed the OWTS for the residence as submitted in our report dated June 2,
2021, Project No. 20-7-744.02. The system was designed for four bedrooms. The OWTS
was installed by you.
We performed our evaluation on May 14, 2024. The OWTS components observed included:
sewer line, cleanout, septic tank, effluent line, distribution box 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 distance locations to the septic tank shown on Figure 1 were made
by taping.
The proposed Tuftite 4-hole distribution box was changed to a Polylok 6-hole distribution box.
The change is acceptable to us.
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.
