Written questions regarding the solicitation must be submitted via the Bonfire platform no later than 4:00 PM Central on Friday, May 15, 2026. The initial contract term is one year with automatic renewal for four additional one-year periods under the same pricing, terms, and conditions unless NTMWD provides sixty days' written notice of non-renewal.
