Viega North America, a subsidiary of the Viega Group, announced its new manufacturing facility in Mantua, Ohio, has officially earned LEED Gold (Leadership in Energy and Environmental Design) certification. Succeeding the plant’s official opening in September 2025, this certification recognizes its sustainable design, energy efficiency and reduced environmental impact.

The Mantua facility, now listed under LEED Project ID #1000190658, will soon appear on the U.S. Green Building Council (USGBC) project directory where additional project details and imagery will showcase the project's sustainability achievements.

Earning LEED Gold certification is a crucial step in the company’s dedication to environmental stewardship in both products and operations.

 “LEED is a transformative tool that ensures a building is designed and operated to achieve high performance, improve human health and protect the environment,” said Peter Templeton, president and CEO, USGBC. “By prioritizing sustainability, the Mantua facility is leading the way in its industry and helping USGBC continue towards our goal of green buildings for everyone within this generation.”

The Mantua Facility Incorporates:

• Energy-efficient building systems: Advanced automation and robotics drive reduction in overall energy use, increasing throughput, repeatability and dimensional accuracy.
• Fully electrified plant: An electrical backbone enables efficient processes today and a clear pathway to renewables tomorrow.
• Energy-efficient design: The building utilizes a high-performance envelope, lighting and controls to reduce energy and water use.
• Waste reduction: The facility incorporates processes that contribute to a reusable framework.

“This achievement reflects our long-held belief that manufacturing can be both innovative and sustainable,” said Marki Huston, CEO of Viega North America. “Our LEED-certified Mantua facility is a key step towards building a better future for our customers, employees and the environment.”

Driving U.S. manufacturing growth and next steps

During the first two years of operation, the Mantua facility is projected to create approximately 68 new jobs for Northeast Ohio. These roles reflect a range of skills including operations, maintenance, quality, logistics and training, and come with growth paths and a strong safety culture.

This facility will manufacture key components of Viega’s press technology portfolio. Production of ProPress fittings is underway, with MegaPress capacity planned as the plant scales. Additionally, Viega will continue to invest in its robust on-site seminar center and training resources to support key customers across the eastern U.S. and Canada.
