Overview
New York, NY – Feb 03, 2026 – The Global Water Testing Market is projected to reach USD 7.4 billion by 2034, up from USD 4.3 billion in 2024, reflecting a 5.6% CAGR from 2025 to 2034. In 2024, North America led the market, accounting for 49.3% of global revenue and generating nearly USD 2.1 billion in water-testing activities.
The water-testing ecosystem cuts across municipal utilities, industrial facilities, power plants, commercial laboratories, on-site rapid testing solutions, and online analyzers embedded within treatment systems such as desalination and water-reuse plants. This broad value chain continues to expand as operational risks, compliance requirements, and energy-water interdependencies intensify.
A significant share of global demand comes from the energy sector, particularly desalination. According to the IEA, around 21,000 desalination plants now operate across ~150 countries, and global energy consumption for desalination has nearly doubled since 2010—with projections indicating another doubling by 2030. Given that desalination often requires more than 1 kWh per m³ of treated water, the Middle East alone recorded desalination energy usage in 2023 equal to half of the region’s residential energy consumption. These conditions are encouraging utilities to adopt more efficient inline sensors, salinity and boron analyzers, metals testing, and DBP-precursor monitoring to optimize pre-treatment and reduce operational costs.
Regulatory actions are also reshaping testing requirements. The EU’s revised Drinking Water Directive (2020/2184) introduced risk-based monitoring and a rolling watch list. Since January 2022, utilities have been required to test for endocrine-disrupting compounds such as β-estradiol and nonylphenol, which has expanded laboratory workflows for ultra-trace organic analysis.
In the United States, the Bipartisan Infrastructure Law allocates more than $50 billion to drinking-water and clean-water programs, including $15 billion specifically for lead service line replacement—work that necessitates extensive testing for lead, corrosion by-products, and post-replacement verification. In India, the Jal Jeevan Mission continues to deepen the testing footprint: by 1 February 2025, 79.74% of rural households had tap-water access, up from 17% in 2019, significantly increasing bacteriological testing, chlorine-residual checks, and network-level compliance sampling.

Regional Analysis
North America leads the water testing market with a 49.3% share in 2024, valued at $2.1 billion
In 2024, North America remained the leading region in the global water testing market, accounting for 49.3% of total revenue, which translates to approximately $2.1 billion. This strong position is supported by the region’s advanced regulatory landscape, well-developed infrastructure, and rising public focus on water quality. The United States continued to drive much of this momentum, recording more than 58 million individual water tests during 2024. Of these, around 41% were carried out for industrial compliance, while 26% targeted the safety of drinking water supplies.
Top Use Cases
Drinking-water compliance and public health protection: Water testing is most visible in municipal drinking-water systems, where utilities must prove water is safe from source to tap. This use case is growing because service gaps remain large: in 2022, 2.2 billion people still lacked safely managed drinking-water services, keeping routine microbial and chemical monitoring in focus for governments and operators. Risk-based programs also expand what gets tested, including trace contaminants that require sensitive lab methods and more frequent sampling.
Lead pipe replacement and corrosion control verification: A major day-to-day use case is testing around lead exposure risk—especially where old service lines and household plumbing can leach lead. In the U.S., EPA’s Lead and Copper Rule Improvements (LCRI) requires systems to identify and replace lead service lines within 10 years, increasing lead sampling, corrosion-control testing, and post-replacement verification. Funding policy supports this: the Bipartisan Infrastructure Law delivers more than $50 billion to EPA for drinking water, wastewater, and stormwater upgrades, including $15 billion dedicated to lead service line replacement.
Desalination plant monitoring and the energy–water nexus: Desalination is pushing demand for continuous analyzers because water quality shifts quickly and treatment is energy-intensive. The IEA reports about 21,000 desalination plants operating in around 150 countries, and notes that global energy demand for desalination has nearly doubled since 2010 and is on track to double again by 2030—all of which increases the need for real-time monitoring of salinity, boron, metals, and membrane integrity.
Wastewater discharge compliance and safe reuse: Wastewater testing is a core use case for cities and industries, because discharge permits require proof that pathogens, nutrients, and chemicals are controlled. The scale is huge: in 2024, only 56% of global domestic wastewater (about 332 billion m³) was safely treated, meaning many systems need tighter monitoring to reach safe-treatment benchmarks. Where water reuse is expanding, testing becomes even more frequent to validate treatment performance before reuse in industry, landscaping, or groundwater recharge.
Conclusion
In conclusion, the water testing market is evolving rapidly in response to growing environmental, regulatory, and public health demands. With millions of people worldwide still lacking access to safely managed drinking water, and with industrial and municipal sectors expanding their quality monitoring needs, water testing remains an essential part of modern infrastructure. The dominance of chemical testing reflects ongoing requirements for precise detection of contaminants, while newer natural and sensor-based technologies are gaining traction for real-time, eco-friendly analysis.
Regulatory initiatives, such as expanded contaminant monitoring under the EU Drinking Water Directive and major funding efforts like the U.S. Bipartisan Infrastructure Law, are driving more frequent and rigorous testing protocols. At the same time, massive use cases—from desalination plants in over 150 countries to wastewater treatment challenges where only 56% of domestic wastewater is safely treated—highlight the ongoing need for reliable, scalable testing solutions.
