Description

The National Park Service is seeking a qualified contractor to provide wastewater‑treatment‑plant operations, maintenance, and related support services at Yosemite National Park. The work covers day‑to‑day plant operation, regulatory compliance, routine maintenance, data reporting, and safety oversight for the Wawona Wastewater Treatment Plant over an 18‑week period. The contractor must supply a licensed operator, provide own lodging and transportation, and meet California Grade‑2 certification requirements. • Operate and maintain a 105,000‑gal/day wastewater treatment plant (SCADA‑controlled) from late August through late December 2026. • Provide one qualified operator (40 hrs/week) with required California wastewater, water‑treatment, and water‑distribution licenses. • Deliver daily operation logs, monthly payroll reports, and ensure compliance with NPDES and park environmental standards. • Contractor bears all lodging, transportation, uniform, and safety‑equipment costs; no equipment repair or sludge hauling is included.

Budget estimate

$250,000 – $400,000

Based on the prior related award of $300,000 for a similar wastewater‑operator contract at Yosemite and the four‑month performance window, the contract value is likely in the low‑to‑mid‑hundreds‑of‑thousands range. Assuming hourly labor rates around $27 + $5.55 fringe plus overhead, plus minimal equipment costs, a reasonable estimate is roughly $250,000 to $400,000.
