Water Quality Sensor Market Report 2025-2032: Emphasizing Sustainable Development Goals

Market Overview and Growth Projections

The global water quality sensor market was valued at USD 5.72 billion in 2024 and is projected to reach USD 9.47 billion by 2032, exhibiting a compound annual growth rate (CAGR) of 6.51% during the forecast period from 2025 to 2032. This growth is primarily driven by the increasing industrial water discharge and frequent contamination incidents, which have accelerated the adoption of advanced sensors for continuous water quality monitoring.

Key contaminants such as heavy metals, pathogens, and chemicals necessitate the use of high-precision sensors including Total Organic Carbon (TOC), pH, and multi-parameter sensors. These technologies align with the United Nations Sustainable Development Goals (SDGs), particularly SDG 6 (Clean Water and Sanitation) and SDG 12 (Responsible Consumption and Production), by promoting sustainable water management and pollution reduction.
