High-volume semiconductor manufacturing (HVSM), with its
associated high demands for freshwater, is often located in
regions with limited water resources. This nexus of water
demand and scarcity has generated concerns among municipal
governments, prompting several to consider water supply
restrictions as they plan for economic growth and development.
By assessing water use data and economic valuations of land use
from Chandler, Arizona, this study compared the economic benefit
of HVSM with three alternative water uses: office, retail, and
general manufacturing. Normalizing the economic benefit to net
water use (after reclamation) had a marked effect on the fiscal
consequences of water uses. The effects generated by mostly
nonconsumptive water uses (such as HVSM and general
manufacturing) increased significantly relative to less water-intensive,
but more consumptive, water uses. Results showed
that water-intensive land uses need not be avoided in
communities where water is scarce, provided the community
has the facilities necessary to reclaim the wastewater.
