The next great factory migration is already underway, and almost no one is talking about what is actually driving it.

Marcus Tillman opened his water bill in April 2023 and stared at a number that had jumped 34 percent in eighteen months. He lives in Chandler, Arizona, twelve miles from the TSMC semiconductor plant that broke ground in 2021. He did not connect those two facts for almost a year. And that gap between what is happening and what residents understand is exactly the story worth telling here.

I dug into the actual research so you do not have to. Here is what I found: manufacturers are not chasing cheap labor anymore. They are chasing water, and they have been quietly doing it for over a decade. Here are 7 things you probably do not know about this shift.

1. Water Has Quietly Replaced Labor as the Primary Site Selection Factor for Heavy Industry

This one will reframe everything else on this list. A 2023 study published in Nature Sustainability found that 64 percent of the world’s major river systems now face interference from industrial and agricultural withdrawal at levels that threaten long-term viability. Site selectors at firms like CBRE and JLL have confirmed in trade publications going back to 2019 that water access has moved into the top three criteria for industrial location decisions, above wage rates in most manufacturing categories above light assembly. Think of it this way: labor can be trained, automated, or imported. Water cannot be manufactured. Once that reality lands, the rest of this list starts to feel less like trivia and more like a pattern.

2. The TSMC Arizona Plant Is a Water Story, Not a Chip Story

The headline was always about semiconductors, national security, and supply chain independence. The real story behind the headlines is that TSMC’s Phoenix facility requires approximately 9 million gallons of water per day at full operation, according to the Arizona Department of Environmental Quality’s 2022 permit filings. Arizona is a desert state already drawing down the Colorado River at rates the Bureau of Reclamation has called unsustainable. During the 2021 construction phase, TSMC disclosed that drought conditions had caused measurable delays in its Taiwan facilities. Ask yourself why they do not advertise this part of the site selection logic. The chip narrative is clean and patriotic. The water extraction narrative is not.

By the Numbers: TSMC’s Arizona facility is permitted for up to 9 million gallons of water per day. The Colorado River, which supplies the region, hit its lowest recorded reservoir levels in 2022, with Lake Mead dropping to 27 percent capacity, according to the U.S. Bureau of Reclamation.

3. The Great Lakes Region Is Experiencing an Industrial Water Rush That Predates COVID

Between 2018 and 2023, industrial water withdrawal permits issued by Great Lakes states increased by 22 percent, according to the Great Lakes Commission’s 2023 Annual Report. That figure does not include agricultural permits, which mask additional industrial-adjacent usage. Michigan, Ohio, and Indiana have collectively approved more large-scale manufacturing site permits since 2020 than in any comparable five-year window since 1978. The proximity to 21 percent of the world’s surface freshwater supply is not incidental. It is the point.

Do you know how much water your city allocates to industrial users versus residential households each year? Most residents have no idea this number even exists, let alone that it is publicly accessible.

4. Semiconductor Fabs Are the Most Water-Intensive Facilities Ever Built at Scale

A single leading-edge semiconductor fabrication plant uses more water per day than a city of 50,000 people, according to a 2022 analysis from the Pacific Institute. The ultrapure water required for chip washing cannot be recycled efficiently with current technology at the volumes needed. Intel’s Chandler campus, operating since the 1980s, has long been one of the top five industrial water consumers in Maricopa County. When Intel announced expansions in 2022 totaling $20 billion across Arizona and Ohio, water planners in both states quietly revised municipal projections. Ohio’s revision, obtained through a public records request by the Columbus Dispatch in 2023, showed industrial allocation growing as a share of total supply by 11 percentage points through 2040.

Pro Tip: You can track industrial water withdrawal permits near you using the EPA’s Discharge Monitoring Report (DMR) database at echo.epa.gov, or the USGS Water Use Data portal at waterdata.usgs.gov. Search by county and filter for industrial categories. Both are free, public, and updated regularly. Most people never look.

5. Textile and Apparel Manufacturing Is Quietly Relocating to the American Southeast Specifically for Watershed Access

This is the one that surprised me most in the research. Vietnam and Bangladesh have faced severe water stress events that disrupted production timelines, with the Mekong River hitting critical low levels in 2019 and again in 2023 according to the Mekong River Commission. Some apparel brands, not yet publicly disclosing this rationale, have begun reshoring light manufacturing to North Carolina, South Carolina, and Tennessee. The Tennessee Valley watershed system offers consistent precipitation and existing industrial water infrastructure. The labor cost gap has narrowed enough that water reliability is now tipping the calculation.

Here is what this actually means for you. When a battery gigafactory announces it is coming to your county, the press release mentions jobs and investment. What it does not mention is the water use agreement that was negotiated before the announcement, typically at the state environmental agency level, with minimal public notice requirements. A 2022 Brookings Institution report on industrial site selection found that in 78 percent of reviewed cases, water use agreements were finalized before any public zoning or community input process began. That is not an accident. That is a process designed to minimize friction.

Did You Know? A 2022 Brookings Institution analysis found that in 78 percent of large industrial site selections reviewed, water use agreements were signed before public zoning hearings were scheduled. Residents were informed after the terms were locked.

7. The Water-Manufacturing Nexus Is Creating a New Class of Regional Winners and Losers

The Mississippi River basin, the Ohio River valley, and the Pacific Northwest are all seeing renewed industrial interest for the same underlying reason: freshwater access that other global regions cannot replicate. Meanwhile, regions that attracted manufacturing in the 1990s and 2000s based on labor cost, particularly parts of the American Southwest and Sun Belt, are now watching that same manufacturing consider moving again as aquifer depletion accelerates. A 2024 report from the American Water Works Association projects that 40 percent of U.S. counties will face moderate to high water stress by 2050. The factories know this. The relocation decisions being made right now reflect that knowledge. The question is whether residents and local officials are reading the same data. Are you paying attention to where the water in your region actually goes?

Multiple Perspectives

Not everyone reads this trend as cause for alarm. Brookings researchers and several economic development economists argue that manufacturing reshoring near freshwater assets is a rational and stabilizing correction, moving production closer to both resources and consumers and reducing global supply chain fragility. The counterargument from environmental advocates, including the Natural Resources Defense Council, is that industrial water rights acquired now will lock in extraction patterns for 30 to 50 years, well past the point where climate projections suggest those extraction levels will be sustainable. Both positions are legitimate. The tension between them is where policy actually needs to happen.

Your Next 3 Steps

Step 1: Look up your state’s industrial water permit database. In Ohio, that is the Ohio EPA’s Division of Surface Water permit search at epa.ohio.gov. In Michigan, use the EGLE database at michigan.gov/egle. In Texas, search the TCEQ Water Rights database at tceq.texas.gov. Most permits are public record and searchable by county. Find out who holds large industrial permits near you and when they were issued.

Step 2: Pull your city or county’s most recent Water Master Plan. This is a public document, usually updated every five years, and it will show you how industrial allocation has grown as a share of total water supply since 2018. Search your city name plus “water master plan” plus the most recent year. If industrial allocation has grown faster than residential allocation, that gap is worth understanding.

Step 3: Attend or watch the next meeting of your local public utility commission or zoning board where a manufacturing expansion is on the agenda. Water allocation items are frequently buried inside consent calendar votes that pass without discussion. Bring the Brookings statistic about pre-zoning water agreements. Ask the question publicly. You will be surprised how few people in the room have asked it before.

The factories are not coming for your jobs. They are coming for your water. The difference between a community that benefits from that and one that simply loses its aquifer is whether residents understood the deal before it was signed. Now you know enough to find out.
