Water Supply & Irrigation Systems in the US Industry Data and Analysis
Over the past five years, water supply and irrigation systems companies have experienced modest growth, primarily driven by increased water prices due to scarcity. Prolonged droughts in regions like Texas, California and Arizona have heightened dependence on surface water, escalating demand and prices. While the residential construction sector struggled with high interest rates in recent years, 2024 and 2025 have seen these rates lowered, setting up a revival in demand from the residential segment. Meanwhile, growth in the commercial market has been constrained due to increased remote and hybrid work, keeping office rental vacancies high and impacting water consumption. Overall, industry revenue has grown at a CAGR of 3.4% over the past five years, reaching an estimated $120.0 billion after a 1.1% increase in 2025.
