Wyo. Stat. § 41-7-412 (2026)

In all cases where the work to be done at any one (1) time under
the direction of the commissioners will, in their opinion, cost
to exceed seventy-five thousand dollars ($75,000.00), the same
shall be let to the lowest responsible bidder, and the
commissioner shall advertise for sealed bids, by notice
published in some newspaper published in the county in which the
petition is filed, and may advertise in one (1) or more
newspapers published elsewhere. If there be no newspaper
published in the county in which the petition is filed, they
shall advertise in some newspaper published in an adjoining
county, which said notice shall particularly set forth the time
and place when and where the bids advertised will be opened, the
kind of work to be let and the terms of payment. Said
commissioners may continue the letting from time to time, if in
their judgment the same shall be necessary, and shall reserve
the right to reject any and all bids. This section shall not be
construed to apply to the employment of superintendent,
engineer, attorney or other employee engaged in the general work
of the district.
