Subject: Certification of Onsite Wastewater Treatment System, Proposed Accessory
Dwelling Unit (ADU), 411 County Road 237 (Harvey Gap Road), Garfield
County, Colorado
Dear Jason:
A representative of Kumar & Associates observed the installation of the Onsite Wastewater
Treatment System (OWTS) for the ADU 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 April 16, 2024.
We previously designed the OWTS for the ADU as submitted in our report dated June 19, 2024,
Project No. 24-7-244. The system was designed for two bedrooms.
We performed our as-built evaluation on September 17, 2024. The OWTS components observed
included: sewer line, cleanout, septic tank, distribution box, effluent line 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 septic tank was changed from a Valley Precast 1,000-gallon, two-chamber tank to an
Infiltrator 1,060-gallon, two-chamber tank. 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 observation 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
