Market Overview

The global industry focuses on cleaning water for consumption or safe disposal through equipment, chemicals, and services. Wastewater treatment refers to the removal of impurities from wastewater, or sewage, before it reaches aquifers or natural bodies of water like rivers, lakes, estuaries, and oceans. Since pure water is not found in nature (i.e., outside chemical laboratories), any distinction between clean water and polluted water depends on the type and concentration of impurities found in the water as well as on its intended use. In order to address the increasing demand for clean water supplies for key industrial, agricultural, and municipal activities, water and wastewater treatment are essential.

Innovation and market expansion are anticipated as a result of major players' growing R&D expenditures and expanding partnerships. For instance, in November 2025, Premier Tech and National Research Institute for Agriculture, Food, and the Environment (Institut national de recherche pour l'agriculture, l'alimentation et l'environnement, INRAE) are joining forces to advance research on the reuse of treated wastewater from decentralized systems. With industrial modernization, the upsurging need for advanced and smart technologies is increasing, and the implementation of smart water and wastewater treatment technologies complies with stringent regulations, enabling high-quality service with stringent control on operational costs.

Driving Factors

Strict regulations on Effluent Treatment

The Environmental Protection Agency (EPA) of the U.S., the European Union Water Framework Directive, and other agencies are driving the adoption of water and wastewater treatment solutions to address water pollution and enable sustainable water management practices.   

Urbanization and Population Growth

Major urbanites live in overcrowded, unplanned settlements with inadequate water and sanitation services. Urban areas are expected to absorb all of the world’s population growth in the coming decades, as well as accommodate rural to urban migration. Urbanization increases the pressure on water sources as populations become more concentrated in specific areas. The development-driven rise in per capita water consumption further increases the demand for water, straining the local water capacity. Thus, population growth is driving an increase in the demand for water and resulting in water pollution and the depletion of water resources.

Restraining Factors

Increased cost of wastewater treatment

An increased wastewater treatment equipment due to its complexity, that require skilled personnel for operation and monitoring. Balancing these efficient treatments with high capital expenses and maintenance costs is challenging for stakeholders in the market.

Market Segment Insights

By Segment: Services (Largest) versus Chemicals (Emerging)

The services segment held the largest market share of around 60.0% in 2024, owing to the growing emphasis on constructing novel treatment plants and maintaining existing facilities for wastewater treatment. The segment includes design & engineering consulting, building & installation, operations & process control services, and maintenance & repair services. While chemicals used in water and wastewater treatment include coagulants (like alum, ferric chloride) and flocculants (like polymers) for removing solids, pH adjusters (like sulfuric acid, lime) are used for neutralization.

By Application: Municipal (Dominant) versus Industrial (Emerging)

The municipal segment held the dominant share in the water and wastewater treatment market, owing to growing urbanization, environmental regulations, and the increasing need for clean water. Municipal wastewater treatment includes processes such as sedimentation, biological treatment, disinfection, and sludge handling, which are designed to remove pollutants before safe discharge or reuse. Industrial wastewater treatment involves handling specific, high-strength, toxic, or complex pollutants in industries. They often use advanced technologies such as membrane bioreactors and ion exchange to meet stringent regulations, often for water reuse.
