Alabama Pipe Makers Supply Water Systems Nationwide

EPA Region 4 Administrator Kevin McOmber and ADEM Director Edward Poolos toured ductile iron pipe manufacturing facilities in Alabama on October 28 and 29, 2026. The visits cover all three of the nation's domestic ductile iron pipe producers, which are headquartered in Birmingham and supply operators running water and wastewater systems.

Why it matters

The tours put a spotlight on the domestic supply base for pipe and fittings used in water and wastewater infrastructure, a category where local producers serve systems nationwide. For operators in manufacturing, utilities contracting and metal recycling, it is a reminder that the production chain for this material is concentrated in a single state.

The visits covered all three of the nation's domestic ductile iron pipe producers over two days, a complete census of U.S. domestic producers rather than a sample. The figures reported do not include production volume, workforce size, or investment totals, so the scale of the Alabama base cannot be quantified from this report.

The players

U.S. Environmental Protection Agency Region 4

The EPA regional office overseeing environmental programs across the Southeast, including rulemaking and enforcement that affect industrial facilities and water infrastructure suppliers.

Alabama Department of Environmental Management

The state agency that issues permits and enforces environmental rules for manufacturers operating in Alabama, including the pipe producers visited on the tours.

McWane

A privately held Birmingham-based manufacturer of ductile iron pipe and fittings, one of the three domestic producers visited during the tours.

American Cast Iron Pipe Company

A Birmingham-based manufacturer of ductile iron pipe and fittings serving municipal water and wastewater systems, one of the three domestic producers visited during the tours.

U.S. Pipe

A Birmingham-based manufacturer of ductile iron pipe and fittings for water and wastewater infrastructure, one of the three domestic producers visited during the tours.

The details

Officials toured manufacturing facilities operated by American Cast Iron Pipe Company, McWane and U.S. Pipe, observing how recycled scrap metal is converted into finished pipe and fittings. They also met skilled workers making pipe and fittings and reviewed investments the companies have made in modern production and environmental controls. The facilities produce pipe and fittings that serve water and wastewater systems across the country.

Market Landscape

The three domestic ductile iron pipe producers, all headquartered in Birmingham, form the core of the U.S. supply base for water and wastewater pipe and fittings. The tours sit within the existing EPA Region 4 and ADEM oversight relationship that governs environmental compliance for these manufacturing sites.

Operators in pipe fabrication, metal recycling and municipal utility procurement should track how regional oversight of these facilities develops, since their supply and compliance costs depend on it. Procurement teams relying on domestic ductile iron pipe should review supplier concentration in Birmingham as part of their sourcing planning.

The takeaway

Operators who buy or sell water and wastewater pipe should note that all domestic ductile iron pipe production is concentrated in one metro area, which makes regional supplier relationships and recycled-metal feedstock sourcing worth documenting now. Procurement leads can use the next round of agency and producer disclosures to benchmark supply reliability against their own contract terms.
