Tank Manufacturing and Industrial Services in Oregon and Washington

Oregon and Washington’s water-rich but infrastructure-aging Pacific Northwest drives demand for new and replacement steel storage tanks — potable water reservoirs, wastewater treatment plant tanks, agricultural water storage, food and beverage processing vessels, and fire protection tanks for wildfire-prone communities east of the Cascades.

MMI Tank is licensed in both Oregon and Washington. Our Phoenix fabrication plant ships bolted tank panels and shop-fabricated components to the Pacific Northwest within two days, and our field crews are experienced with PNW weather conditions and regulatory requirements.

Pacific Northwest Industries

  • Water and wastewater — Portland, Seattle, and hundreds of smaller utilities replacing aging concrete and steel tanks with modern bolted or welded construction
  • Agriculture — Willamette Valley, Yakima Valley, and Columbia Basin irrigation, dairy, and food processing
  • Food and beverage — Oregon and Washington’s craft brewing, winemaking, and food processing industries
  • Fire protection — wildfire water storage for WUI communities east of the Cascades
  • Municipal — urban and rural water districts across both states
  • Industrial — semiconductor, aerospace, and manufacturing operations in the Portland and Seattle metros

PNW Seismic Design

The Pacific Northwest sits atop the Cascadia Subduction Zone — one of the highest seismic hazard regions in the country. Every MMI tank installed in Oregon or Washington includes full seismic analysis per the applicable code (API 650 Appendix E, ASCE 7), including site-specific ground motion parameters. Our engineers are familiar with the unique long-duration seismic demands of subduction zone earthquakes.

Pacific Northwest Tank FAQ

Is MMI licensed in Oregon and Washington?
Yes. We hold contractor licenses in both states for tank construction, steel fabrication, and industrial coatings work.

How long does freight take from Phoenix to the Pacific Northwest?
Bolted tank panels and shop-fabricated components typically reach Oregon and Washington job sites within two business days of shipment from our Phoenix plant.

Does MMI design for Cascadia Subduction Zone seismicity?
Yes. Our engineers design for the long-duration seismic demands specific to the Cascadia Subduction Zone, including site-specific spectral acceleration values and soil amplification factors per ASCE 7 and the Oregon/Washington Building Codes.
