Downstream: what depends on it
Semiconductor fabrication plant requires input Industrial process water2 evidenceEstablished relation
Semiconductor fabrication plant depends on Industrial process water.
Mechanism
Wafer processing rinses with ultrapure water between steps; a fab uses millions of gallons a day. Recycling reduces intake but not the need.

Inputs it cannot do without
Upstream: what it depends on
Industrial process water requires input Renewable freshwater3 evidenceEstablished relation
Industrial process water depends on Renewable freshwater.
Mechanism
Process water is drawn from surface water and groundwater and then purified; regional freshwater availability bounds where water-intensive plants can be sited.
