The $100 Billion Wave Heading for US Water

A new GWI forecast projects US water and wastewater capital spending will cross $100 billion annually by 2030

14 May 2026

America's water utilities are staring down the most expensive era in their history. A state-level forecast from Global Water Intelligence, published in April 2026, projects that annual US water and wastewater capital spending will exceed $100 billion for the first time by 2030. The forces behind it are not subtle: regulatory mandates, climate pressure, and aging infrastructure are all converging at once across dozens of states.

Texas is closing the gap fast. The state is forecast to surpass $14 billion in annual capex by 2030, driven by population growth and a sharp pivot toward drought-resilient investment. That includes seawater desalination, a category entirely absent from GWI's previous 2023 outlook. California, meanwhile, still leads all state markets at $10.8 billion in 2026.

Utilities facing mandatory PFAS removal deadlines and lead service line replacement requirements have little room to delay. Luke Bratt, North America Editor at Global Water Intelligence, confirmed that more spending is now non-discretionary than at any point in two decades. Drought planning and water reuse programs, once considered optional, are absorbing growing shares of capital budgets. At the same time, vast stretches of distribution and treatment infrastructure built in the 1970s and 1980s are reaching end-of-life across multiple regions simultaneously.

Real headwinds remain. Bipartisan infrastructure law funding expires in September 2026, and its reauthorization path is uncertain. Proposed federal cuts to state revolving funds and WIFIA loan programs could strip co-financing that smaller utilities depend on to keep customer rates manageable. GWI's forecast notes that near-term growth moderates through 2028 as affordability pressures force capital plan recalibrations before a final acceleration into 2030.

Navigating the gap between obligation and available capital will define the next two years. For suppliers, contractors, and technology providers active in US water markets, the investment pipeline ahead is large, durable, and legally reinforced.
