Drinking Water Treatment Chemicals Market Forecast Projected to Hit 42.1 (USD Billion) by 2032

The drinking water treatment chemicals market is poised for steady growth, driven by increasing population and urbanization.
Published 05 June 2025

Access to safe and clean drinking water is a fundamental human necessity and a cornerstone of public health. However, rapid industrialization, urbanization, and population growth have placed enormous pressure on water resources. This has led to an increased reliance on drinking water treatment chemicals, which play a crucial role in purifying water and making it safe for consumption. The Drinking Water Treatment Chemicals Market is evolving rapidly in response to environmental challenges, technological innovations, and demand for safe, clean water. As urban populations grow and water resources become increasingly stressed, the importance of reliable and efficient chemical treatment will continue to rise.

The Drinking Water Treatment Chemicals Market has emerged as a vital segment of the water and wastewater treatment industry. These chemicals are used to remove contaminants, neutralize harmful substances, kill disease-causing pathogens, and ensure the water is safe and palatable for human consumption.

Market Overview

Drinking Water Treatment Chemicals Market Size was estimated at 30.55 (USD Billion) in 2023. The Drinking Water Treatment Chemicals Market Industry is expected to grow from 31.66(USD Billion) in 2024 to 42.1 (USD Billion) by 2032. The Drinking Water Treatment Chemicals Market CAGR (growth rate) is expected to be around 3.62% during the forecast period (2024 - 2032).

Key Drivers of Market Growth

1. Rising Water Pollution

Water sources are increasingly contaminated by industrial waste, agricultural runoff, and untreated sewage. This growing pollution has intensified the demand for chemicals that can effectively treat and purify contaminated water before it reaches households.

2. Population Growth and Urbanization

As cities expand and urban populations increase, the pressure on municipal water treatment systems also grows. Urban areas require large-scale treatment facilities capable of delivering safe water consistently, thus increasing the need for efficient chemical treatment processes.

3. Stringent Government Regulations

Governments across the globe are imposing stricter guidelines on the quality of drinking water. Regulations such as the U.S. EPA’s Safe Drinking Water Act and the European Drinking Water Directive mandate the removal of specific contaminants, spurring the demand for advanced treatment chemicals.

4. Technological Advancements

The market is being reshaped by advancements in water treatment technology, including membrane filtration, UV disinfection, and advanced oxidation processes. These technologies work in tandem with chemicals to enhance the effectiveness and efficiency of water purification systems.

Key Types of Water Treatment Chemicals

1. Coagulants and Flocculants

These chemicals are used to remove suspended solids and colloidal particles from water by encouraging them to clump together into larger particles (flocs), which can then be removed through sedimentation or filtration.

2. Disinfectants

Disinfectants such as chlorine, chloramine, and ozone are essential in killing bacteria, viruses, and other pathogens that may be present in water. They ensure microbial safety and are particularly crucial in preventing outbreaks of waterborne diseases.

3. pH Adjusters

Chemicals such as lime or caustic soda are added to control the pH level of water, which is essential for optimizing the effectiveness of other treatment chemicals and protecting infrastructure from corrosion.

4. Corrosion and Scale Inhibitors

These additives prevent scaling and corrosion in distribution systems and household plumbing, thus maintaining the integrity and longevity of water delivery infrastructure.

5. Chelating Agents and Anti-foaming Agents

Used in more complex or industrial-grade water treatment, these chemicals help manage dissolved metals and reduce foam formation in the treatment process.
