The Greycliff Rest Area Rehab project involves comprehensive upgrades to the potable water and wastewater systems at both the eastbound and westbound rest areas along I-90 in Sweetgrass County, Montana, near milepost 381.0. The scope includes reconfiguring the water supply by constructing a new, DEQ-approved public water well at the westbound facility and abandoning the existing eastbound well, while installing a 5,000-gallon buried storage tank, new service piping between buildings, redundant pumps, controls, valves, and appurtenances to ensure reliable service that meets DEQ Circular DEQ-3 requirements for peak demand. The project also replaces the outdated wastewater system with a state-of-the-art Level 2 advanced treatment system featuring new septic tanks, an equalization tank, a dosing tank, effluent pumps, force mains, and a multi-zone pressure-dosed drainfield to ensure regulatory compliance and long-term operational reliability. This initiative is being managed by the Montana Department of Transportation under solicitation number 06826, classified under NAICS code 237110 for Water and Sewer Line and Related Structures Construction. The contract is open to public bid with a posted date and response deadline both set for August 27, 2026, and no set-aside provisions apply. The work is critical to addressing capacity limitations, improving water quality, and ensuring systems operate safely and sustainably for public use. All construction activities will occur within Sweetgrass County, with the MDT overseeing compliance, timelines, and performance standards for the full scope of improvements.
