Perini Management Services, Inc. Awarded $69.5 Million Water and Wastewater Treatment Systems Rehabilitation Project

Key Terms

reverse osmosis technical

A water-cleaning process that uses pressure to force water through a very fine membrane, leaving salts, minerals and many contaminants behind — like pushing juice through an extremely tight sieve so only pure liquid passes. Investors care because reverse osmosis is a core technology for desalination, industrial water recycling and many manufacturing processes, driving capital spending, recurring service revenue and regulatory or environmental risk and opportunity for companies involved.

potable water wells technical

Man-made or drilled openings in the ground designed to access groundwater that is safe to drink and meet local health standards; they include the well casing, pump, and often treatment equipment to keep water potable. Investors care because these wells are critical infrastructure assets for water-dependent businesses and real estate, affecting operating costs, regulatory compliance, liability from contamination, and the value or operability of properties — like a utility hookup that supplies a business with a basic, regulated input.

force mains technical

A force main is a pressurized pipeline that carries wastewater or sewage from a pump station to a treatment plant or a point where it can flow by gravity. Think of it like a garden hose under pressure that pushes wastewater uphill or across distances; investors track force mains because their construction, condition and maintenance affect project costs, service reliability, regulatory compliance and potential environmental liability for utilities and infrastructure projects.

pump stations technical

Pump stations are facilities that use mechanical pumps and controls to move liquids or gases through pipelines or distribution networks, commonly found in water, wastewater, oil and gas, and industrial systems. They matter to investors because they are critical pieces of infrastructure that affect the flow, capacity and reliability of a supply chain—like booster stations on a highway that keep traffic moving—and their performance, maintenance needs, regulatory compliance and lifespan influence operating costs and service continuity.

FRAMINGHAM, Mass.--(BUSINESS WIRE)-- Tutor Perini Corporation (NYSE: TPC) (the “Company”), a leading civil, building and specialty construction company, announced today that its subsidiary, Perini Management Services, Inc. (“PMSI”), has been awarded a contract valued at approximately $69.5 million by the National Park Service for a water and wastewater treatment systems rehabilitation project at Death Valley National Park in California.

The scope of work includes rehabilitating, replacing, and upgrading critical components of the water and wastewater systems within the Furnace Creek and Cow Creek areas of Death Valley National Park. Both areas comprise the park’s primary developed areas and serve the park’s 1.7 million annual visitors, 1,100 residents, and the Timbisha Shoshone Tribe.

Wastewater treatment system improvements include replacing sewer gravity and force mains, service laterals, and pump stations. Water system improvements include an extensive new distribution system inclusive of water mains, laterals, pumps and appurtenances, developing new potable water wells, and reconstructing the reverse osmosis treatment building, chlorination building and control systems. The project also includes repairs and upgrades to improve the capacity of a lagoon.

Work is expected to begin in the fall of 2026, with substantial completion anticipated in early 2029. When completed, the project will eliminate significant deferred maintenance, improve the reliability and resilience of essential utility infrastructure, increase system capacity, enhance public health and environmental protection, and provide dependable water and wastewater service for park visitors, residents, employees, and partners.

The contract value will be added to the Company’s backlog in the third quarter of 2026.
