Water Storage Systems Market Size & Share Analysis - Growth Trends and Forecast (2027 - 2032)

Market Trends and Insights

Freshwater Scarcity and Reliability Requirements

Water stress is reshaping investment priorities in both higher-income and emerging economies. The Food and Agriculture Organization (FAO) reports that more than 40% of the global population lives in water-scarce conditions, which increases the value of storage that separates supply availability from immediate demand. Utilities and industrial operators are therefore treating dedicated storage as a risk-management asset. In August 2025, California approved nearly USD 219 million in additional funding for the Sites Reservoir project, whose total estimated cost is up to USD 6.8 billion^[1]. The project shows how public funding is being directed toward large reservoirs during periods of supply stress. The water storage systems market benefits when assets are designed for extended shortages rather than short operating interruptions, strengthening water storage systems market requirements for resilient capacity.

Municipal and Industrial Water-Infrastructure Investment

Deferred maintenance is bringing more municipal water projects into public procurement pipelines. The U.S. Environmental Protection Agency announced USD 7 billion in Water Infrastructure Finance and Innovation Act funding availability in 2026 for critical water infrastructure^[2]. Pennsylvania Infrastructure Investment Authority awarded USD 547.1 million in a single funding round in 2025. Pennsylvania American Water also committed USD 18.5 million to rehabilitate 7 tanks and construct 5 new tanks in 2025. Larger, multi-year procurement programs favor suppliers with a broad product range and service capability. American Water Works Association (AWWA) C652-2025 establishes requirements for disinfecting water storage facilities, which ties new tank commissioning to a defined compliance process.

Expansion of Rainwater Harvesting and Decentralized Storage

Rainwater harvesting is becoming part of urban water-security planning in several markets. Shanghai issued a 2025 regulation that provides subsidies of up to CNY 15 per cubic meter (approximately USD 2.1 per cubic meter) for qualifying nonconventional water projects that include rainwater collection and storage. Zhejiang Province also published a 2025 rural water supply regulation that identifies backup water sources, reservoir tanks, and storage pools as emergency supply solutions. These measures support decentralized systems in residential and commercial settings. Such projects generally have shorter procurement cycles than large municipal contracts. 

Fire-Safety Reserve Mandates and Resilient Building Design

Building resilience requirements are increasing demand for dedicated on-site fire-water reserves. American Society of Civil Engineers/Structural Engineering Institute (ASCE/SEI) 24-2025 sets minimum flood-resistant design requirements that apply to water storage infrastructure in flood hazard areas. The AWWA placed its composite elevated tank standard, AWWA D107, under public review in 2025. AWWA D140 for cast-in-place concrete tanks also entered a comment period in 2026. These standards shape the specifications used for new facilities and upgrades. Property owners in fire-prone locations are also giving greater attention to autonomous reserves when municipal supply may be disrupted.

High Capital and Installation Cost

Large storage projects can exceed the budgets available to smaller utilities and municipalities. The Passaic Valley Water Commission financed a USD 52.98 million project to replace an open-air reservoir with covered concrete storage tanks through a dedicated infrastructure bank loan. Remote projects add site preparation, foundations, and logistics costs to the tank purchase. These conditions can lead smaller users to delay investment or choose temporary alternatives. Safe Drinking Water Act requirements and American Water Works Association (AWWA) standards create a need for compliant systems, but implementation schedules can still extend capital planning periods. The water storage systems market faces slower project conversion when borrowing costs rise, or local budgets tighten, which can delay water storage systems market orders.

Raw Material Price Volatility

Steel and Portland cement are important inputs for aboveground and elevated tanks. Changes in input costs can narrow fabricator margins, especially on fixed-price municipal contracts. Fiberglass suppliers also face exposure to the cost of glass fiber, resin, and petrochemical feedstocks. Smaller regional fabricators can have less capacity to manage sudden price changes than diversified manufacturers. In January 2026, TerraVest Industries acquired KBK Industries for USD 90 million, adding a manufacturer of fiberglass and steel storage tanks to its portfolio. The transaction shows why access to capital and a broader supply base can matter when materials costs remain unstable.

Water Storage Systems Market Segment Analysis

Concrete held 32.45% share in 2026, supported by its established role in large municipal projects. Municipal engineers are familiar with reinforced concrete designs for high-capacity storage. Long operating lives can also make replacement cycles less frequent in mature networks. The water storage systems industry continues to use concrete where project scale and local construction capability favor the material.

Fiberglass is projected to advance at a 7.97% CAGR through 2032. Its resistance to corrosion and lower maintenance requirements suit wastewater and chemically demanding locations. NOV Fiber Glass Systems reported composite water infrastructure projects in California, Oregon, and Chile during 2025. Steel remains relevant for elevated tanks and large bolted systems, while plastic supports smaller residential and commercial installations. Glass-fused-to-steel and engineered composites serve applications where lifecycle maintenance is important. AWWA D120 was reaffirmed in 2025, retaining a standards reference for thermosetting fiberglass-reinforced plastic tanks used in water supply service.

Aboveground held a 45.67% share in 2026 because its is generally straightforward to construct and access. They remain common in municipal and commercial projects where land is available. Surface systems also allow operators to inspect and service equipment with fewer site constraints. Their use is supported by established engineering practices for standard storage requirements. The water storage systems market size for aboveground applications remains tied to ongoing replacement of visible municipal assets.

Underground is projected to advance at an 8.16% CAGR through 2032. Higher urban land values make belowground storage more attractive where surface space is limited. Buried installations can also protect potable water from temperature changes, algae growth, and surface contamination. Minnesota appropriated USD 734,000 in 2025 for underground water storage tank replacement in Kennedy. Indoor systems serve hospitals, commercial buildings, and data centers that need controlled reserve capacity. Balmoral Tanks Ltd reported in 2025 that data center projects made up 20% of export sales, indicating demand for engineered cooling and fire-protection storage.

Onsite water and wastewater collection held a 30.21% share in 2026. The segment supports treated-water buffering before distribution and is linked to core municipal service delivery.
