OWTS Construction Approval Letter Permit Sept-06-17-4778
The proposed OWTS field design for 271Willow Lane in Garfield County, Colorado has been installed per
the a-pproved and permitted plans (Permit Number Sept-06-17-4778). The installation contractor was Hagist
Excavation, 22612th St, Carbondale, CO 81623
The bed was constructed per plan with the piping being l2'x36' within the gravel bed and 4' of sand above
the excavated grade approximately 1-3' deep from native grade. The addition of a tee and valves was added
at the location going to the old field to have the option of using the old field if conditions would warrant.
The field is located in their general area of design as shown on the following page. The distribution pipes
were placed per plan and can be seen in the attached pictures. Dosing was witnessed on site at the field
locatiın. The inspection ports that were installed were brought to above grade as required per photos. The
existing septic tank, dosing pump and controls were not modified but a recommendation to consider
improving the older controls was discussed with owner.
Attached are photos of the installation.
Please let me know if you have questions pertaining to this acceptance letter submittal.
Thank you,
