Northwest Pipe Company Launches Environmental Product Declaration for Sustainable Water Infrastructure Solutions

### Northwest Pipe Company Enhances Sustainability with Verified Environmental Product Declaration

Northwest Pipe Company, through its subsidiary NWPX Infrastructure, Inc., takes a significant step towards sustainability with the announcement of its first third-party verified Environmental Product Declaration (EPD) for cement-mortar-lined welded steel pipe. Released on October 15, 2025, this EPD provides detailed information regarding the lifecycle environmental impacts of the company's water transmission systems. The declaration aligns with the AWWA Manual M11 standards and is produced in facilities certified with the ISO 9001:2015 Multisite standard, underscoring the company’s commitment to quality and environmental responsibility.

The EPD includes critical metrics on embodied carbon and other significant environmental indicators, making it a valuable resource for engineers, contractors, and municipalities. As the demand for sustainable procurement increases, particularly with the implementation of Buy Clean California mandates, this transparency in environmental impact allows stakeholders to make informed decisions when selecting infrastructure solutions. Northwest Pipe Company aims to leverage this EPD effectively in its marketing strategy, particularly during the commercial bidding process for projects managed by municipalities that prioritize compliance with environmental criteria in their planning and execution.

Scott Montross, President and CEO of NWPX Infrastructure, articulates the company’s dedication to corporate responsibility and sustainability in its operations. He highlights the essential role of their water transmission systems in delivering water across North America for decades, emphasizing that the release of the EPD is a cornerstone of their ongoing commitment to environmental stewardship. Founded in 1966, Northwest Pipe Company has grown to become the largest manufacturer of engineered water transmission systems in North America, diversifying its product offerings while maintaining a focus on innovation and quality.

In addition to its EPD, Northwest Pipe Company’s portfolio includes various solutions such as steel casing pipes and reinforced precast concrete products. This wide array of offerings positions the company as a leader in the water infrastructure sector, enabling it to address the evolving needs of the marketplace while remaining true to its core values of accountability and sustainability. As municipalities increasingly seek to enhance their infrastructure with environmentally friendly materials, Northwest Pipe Company stands ready to meet these challenges head-on, reinforcing its reputation as a trusted partner in the water management industry.
