U.S. water reuse pipeline to drive US$47.1 billion in infrastructure spending through 2035

Water reuse—the process of recycling treated wastewater for beneficial uses—represents a viable cornerstone of resilient water supply planning for utilities, municipalities, and industries, unlocking a potential surge in infrastructure investment across the U.S.

The urgency to secure future supplies—exacerbated by groundwater depletion, saltwater intrusion, and persistent drought—has accelerated the momentum toward broader adoption of reuse, particularly for potable offtake applications.

Sample takeaways:

• CAPEX for municipal reuse infrastructure and treatment systems are forecasted to average US$47.1 billion from 2025 through 2035.
   
• Potable reuse accelerates alongside irrigation demands, signaling a strategic shift toward higher-value, supply-resilient applications for some communities.

• California, Colorado, and Texas anchor the U.S. reuse market and are expected to account for 72% of the forecasted capacity additions.
