Fuelled by AI, Micron's $50 billion chip factory in Idaho will use billions
of litres of water every year but the US tech giant stays silent on where that new water will come from

Description:
Microns Idaho expansion will sharply increase water use, raising concerns
over sourcing, transparency, and long-term sustainability in a desert region

While its existing factory already consumes 4.7 million gallons of water each day, and the first new fab would push daily usage to 10.2 million gallons - enough to fill roughly 15.5 Olympic-sized swimming pools every single day. A second, slightly smaller facility is also planned, which would add even more water demand on top of that figure.

It also receives water from the Nampa Meridian Irrigation District, which pulls from the Boise River, and additionally purchases treated water from Veolia, a private municipal water utility.

A 2024 environmental impact statement for the first expansion revealed that the new fab would use 5.5 million gallons daily and discharge about 2.9 million gallons back into the system.

When asked how much water the new fabs will use and where that water will
come from, Micron refused to provide specific answers, with a company spokesperson offering only a general statement about water efficiency commitments and conservation targets. Are you a pro?

Micron has promised to achieve a 75% water conservation rate globally by the year 2030 through recycling and reuse programs.

However, the company did not explain how that target applies to the new Boise fabs or where the additional water will be sourced.

Veolia also did not respond to questions about how much water it supplies to Micron from its treatment plants. What to read next We are only able to supply, for our key customers in the midterm, about 50% to two-thirds of

In the 1990s, Micron caught significant public criticism when its manufacturing operations caused a sharp drop in local groundwater levels.

The state established a groundwater management area around the company in
1994 to monitor and oversee water rights.

Even today, the Idaho Department of Water Resources can only see a partial picture of Micron's total water usage through its permitted rights.

The company has not filed an environmental impact study for the second fab, leaving regulators and the public completely unaware of its total future
water demand.

Idaho residents rely on the same aquifers that Micron pumps from, and any significant drop in water levels would affect homes, farms, and businesses across the region.

Micron's silence on where it will find billions of litres of new water is not just a lack of transparency; it is a gamble on a resource that the desert cannot easily replace.

The company's plans are fuelled by AI demand, but AI does not run on water; people and crops do, and they have no backup plan if the wells go dry.
