RE: O’Sullivan Residence OWTS Record Affirmation
RECORD AFFIRMATION (November 2023):
In October of 2023 SGM visited the site and, in
conjunction with Walters Company data, photos
and a video of the spray test, we can affirm the
design and installation satisfies the plan
provided at permit. Some minor, location
modifications were made, such as the highpoint
ADV distribution box was a few feet different
than plan, horizontally, but actually made for
even better drain back capabilities.
The size, location, and materials were as per
plan or approved equals. Provided for this
Record information is the site plan, Valley
Precasts’ letter of affirmation, and this design
report with the added affirmation note.
