Water storage systems market seen topping $28 billion by 2030

The global water storage systems market is projected to exceed $28 billion by 2030, with Asia-Pacific and the U.S. leading regional and national growth. Rising water scarcity, urbanization and government infrastructure spending are driving demand for tanks and reservoirs across residential, municipal and industrial uses.

Why it matters: - Water storage systems are becoming a bigger part of the broader water infrastructure market as governments, utilities and private users look for more reliable supply amid water scarcity and climate pressure. - The market’s projected rise points to stronger demand for tanks, reservoirs and monitoring systems across homes, farms, cities and industrial sites. - The business opportunity is spreading across materials, geographies and end-use sectors, which matters for manufacturers, distributors and investors tracking infrastructure and utilities.

What happened: - The Business Research Company published its Revenue from the Water Storage Systems Global Market Report 2026 – Market Size, Trends, And Forecast 2026-2035 on Oct. 13, 2026. - The report projects revenue from the water storage systems market will exceed $28.23 billion by 2030. - The market is forecast to grow at a 7% compound annual rate through 2030. - Asia-Pacific is projected to be the largest regional market by 2030 at $11 billion, up from $8 billion in 2025. - The United States is projected to be the largest national market at $6 billion by 2030, up from $5 billion in 2025.

The details: - Water storage systems are estimated to account for about 5% of the broader Water Supply & Irrigation Systems market, which is expected to reach about $526 billion by 2030. - Within the Utilities industry, water storage systems are expected to represent nearly 0.3% of the market, which is projected to total $9,379 billion in 2030. - Plastic tanks are forecast to dominate the market in 2030 with 38% share, or about $11 billion. - The market is segmented by material into steel, fiberglass, concrete, plastic and other materials. - The market is segmented by location into underground, indoor and outdoor systems. - Applications include onsite water and wastewater collection, potable water storage, fire suppression reserves and rainwater harvesting. - End users include residential, commercial, municipal and industrial customers. - In 2025, Paul Mueller Company ranked as the top global player with a 1% share of the market. - The top 10 companies accounted for only 5% of total revenue in 2025, showing a fragmented market. - The report names companies including CST Industries, Caldwell Tanks, Tank Connection, DN Tanks, Balmoral Tanks, Maguire Iron, Superior Tanks, Aquamate Tanks and Premier Tech Aqua. - The report lists Elkhart Plastics as a product innovator in May 2025, when the company introduced vertical water storage tanks for commercial and residential use. - Those tanks use UV-resistant, FDA-approved polyethylene and include dual manway lids, integrated air bleeds and multiple connection points. - The report also names major raw material suppliers, distributors and end users across the supply chain. - A free sample and the detailed report are available online.

Between the lines: - The forecast suggests demand is being driven less by one end market and more by multiple structural pressures at once: scarcity, urban growth, emergency preparedness and infrastructure replacement. - Plastic’s lead reflects the market’s preference for lower-cost, lighter and corrosion-resistant products that are easier to install and move. - The fragmented share profile suggests no single company has strong dominance, leaving room for regional manufacturers and specialized suppliers to compete on customization, compliance and digital monitoring. - The report’s emphasis on smart monitoring and corrosion-resistant materials points to a market moving from basic storage toward managed water resilience.

What's next: - The fastest growth opportunities appear to be in plastic, concrete, fiberglass and steel, which the report says will generate more than $7.3 billion in additional market value by 2030. - Asia-Pacific’s growth is expected to be supported by water infrastructure spending, conservation initiatives and new public utility projects. - U.S. demand is expected to stay tied to replacement of aging infrastructure, resilient municipal systems and sustainable water management. - Manufacturers are expected to keep pushing modular tanks, advanced materials and smart leak-detection tools as the market expands.
