Point-of-Use Water Treatment Market Projected to Reach $16.38 Billion by 2031, Signalling Opportunities for Maritime Operators

## Point-of-Use Water Treatment Market Set for Steady Growth Through 2031 The global point-of-use (POU) water treatment systems market is forecast to expand from USD 12.13 billion in 2026 to USD 16.38 billion by 2031, representing a compound annual growth rate (CAGR) of 6.2%, according to an exclusive report published by MarketsandMarkets. While the broader market encompasses residential, commercial, and industrial applications, the findings carry relevance for the maritime sector, where access to safe, treated potable water remains a critical operational and regulatory concern. Vessel operators, cruise lines, offshore platform managers, and port facility administrators are among the maritime stakeholders who rely on point-of-use water treatment technologies to meet health standards and crew welfare requirements. ### Why This Matters for Maritime Ships operating on extended voyages must maintain reliable onboard water treatment systems to comply with international health regulations, including standards set out under the Maritime Labour Convention (MLC 2006) and guidelines from the World Health Organization (WHO) for safe drinking water aboard vessels. POU systems — which treat water at the point of consumption rather than at a central source — offer a practical, scalable solution for vessels where centralized watermaking capacity may be limited or where water quality from bunkering ports cannot be guaranteed. The growth trajectory identified by MarketsandMarkets reflects increasing awareness of waterborne health risks, tightening regulatory frameworks, and advances in filtration and purification technologies such as reverse osmosis, ultraviolet (UV) disinfection, and activated carbon filtration — all of which are widely deployed in marine environments. ### Market Drivers According to the report, key drivers of market growth include rising concerns over water contamination, growing demand from emerging economies, and continued innovation in compact, energy-efficient treatment technologies. For the maritime industry, the push toward more sustainable vessel operations and the increasing focus on crew health and welfare are likely to accelerate adoption of advanced POU systems fleet-wide. Port infrastructure operators may also find opportunity in this growth trend, as modern port facilities increasingly invest in high-quality water supply systems to service visiting vessels and support terminal operations.
