Moreover, the rising demand for energy-efficient and advanced water treatment technologies is expected to offer growth opportunities for the players operating in this market.
With rapid population growth and urbanization, the global demand for water supply and sanitation services is also increasing. According to the World Health Organization, in 2022, 57% of the global population, or 4.6 billion people, used safely managed sanitation services, while 33% (2.7 billion people) used private sanitation facilities connected to sewers from which wastewater was treated. Thus, the significant use of water supply and sanitation services is driving the adoption of water and wastewater treatment technologies globally.
Furthermore, the growing population has led to an increase in industrial production. Most industries heavily depend on water for the processing, cooling, and disposal of waste products. The demand for water in industrial applications is rising due to increased industrialization. Many industries worldwide are facing a water shortage and are increasingly looking for ways to reduce water consumption and reclaim and reuse wastewater. The planned use of treated wastewater can increase resource efficiency and benefit the environment, improving the sustainability of industrial development. Thus, industrialization, population growth, and urbanization are driving the adoption of water and wastewater treatment solutions, supporting market growth.
Additionally, stringent water treatment regulations are pushing industries and municipalities to adopt advanced water and wastewater treatment solutions. Governments are implementing stricter environmental standards, encouraging technological innovation, and fostering investments in sustainable water management practices, further accelerating market growth and ensuring long-term water resource availability.
Demographic changes, economic development, urbanization, and pollution are increasing the burden on the world’s water resources. According to the World Health Organization (WHO), as of March 2023, approximately 2 billion people worldwide lacked access to safe drinking water, of which 771 million people lacked access even to basic drinking water. The demand for water is projected to exceed the available supply by 40% within the next 20 years, primarily due to issues related to poor sanitation and water management.
Furthermore, companies operating across various industries are investing in water and wastewater treatment solutions. For instance, in September 2022, LANXESS AG (Germany), a chemical manufacturer, commissioned a new wastewater treatment plant at its Belgium site, with an investment of around USD 13.0 million (EUR 12 million). The plant has a treatment capacity of around 260,000 liters of wastewater per hour.
Moreover, rising water pollution has led to a decline in the availability of freshwater necessary for various industrial applications, such as processing, washing, diluting, and cooling. The rapid depletion of freshwater resources, coupled with industrialization and pollution, has resulted in a water crisis in many parts of the world, especially underdeveloped and developing countries. This water crisis is boosting the demand for water and wastewater treatment solutions, driving the growth of this market.
Water and energy have always been crucial for socioeconomic growth; their supply and use must be sustainable. Water provisioning and use require energy in all phases. Water gets treated to drinking water standards through various processes, including filtration, sedimentation, and disinfection, which require energy. Additionally, wastewater treatment plants are essential for ensuring that communities have access to clean water. However, these plants are notorious for being energy-intensive facilities that consume large amounts of electricity. According to the US Environmental Protection Agency (EPA), wastewater treatment plants are the third-largest energy consumers in municipalities, accounting for up to 35% of a city's total energy consumption. Therefore, it is crucial to find ways to increase energy efficiency at these facilities to reduce operating costs and minimize the environmental impact.
Proper maintenance and operation help ensure that motors, pumps, and overall pump systems work efficiently. Pump optimization with SCADA systems or pump optimization software is a secondary consideration. Furthermore, supplying energy-efficient ballasts for plant fluorescent fixtures and ultraviolet disinfection or pretreatment systems can reduce energy consumption.
As energy efficiency becomes a priority, stakeholders are increasingly investing in innovative technologies such as membrane bioreactors, solar-powered desalination, and energy recovery systems. These advancements not only reduce operational costs but also align with global sustainability goals. Moreover, regulatory incentives and public demand for eco-friendly solutions are motivating market players to prioritize the development of energy-efficient water treatment systems, opening new growth avenues and expanding their market presence.
As urban populations expand and industrial zones emerge in remote or underserved regions, decentralized water treatment offers a cost-effective, scalable, and efficient solution compared to traditional centralized systems. These systems are gaining traction in rural areas, industrial clusters, and developing economies where infrastructure is limited or costly to implement.
Simultaneously, the integration of digital technologies such as IoT-enabled sensors, AI-powered analytics, and cloud-based monitoring platforms is transforming water management practices. These smart systems enable real-time monitoring, predictive maintenance, and efficient resource management—offering enhanced transparency, compliance, and operational optimization. Stakeholders that invest in modular, tech-driven, and sustainable solutions will benefit from increasing demand across municipal, industrial, and commercial segments, especially in regions facing water stress, aging infrastructure, and regulatory pressure to enhance water efficiency and quality.
Based on type, the water and wastewater treatment market is segmented into wastewater treatment and water treatment. In 2025, the wastewater treatment segment is expected to account for a larger share of 63.0% of the water and wastewater treatment market. The large market share of this segment is attributed to the rising focus on water quality and public health, the growing prevalence of water-borne diseases and stringent governmental regulations, and the rising expansion of industrialization and urbanization.
Also, this segment is expected to register the highest CAGR during the forecast period due to technological advancements, increased regulatory pressure, rising environmental concerns, enhanced wastewater recycling initiatives, and growing demand for sustainable solutions.
Based on offering, the water and wastewater treatment market is segmented into treatment technologies, treatment chemicals, process control and automation, design, engineering, and construction services, and operation and maintenance services. In 2025, the operation & maintenance services segment is expected to account for the largest share of 39.5% of the water and wastewater treatment market. The segment’s large market share is attributed to the growing need to ensure the production of the desired quality and quantity of treated water, the increasing complexities of water and wastewater treatment facilities, and the adoption of innovative solutions and stringent regulatory standards.
However, the process control & automation segment is projected to register the highest CAGR during the forecast period. The growth of this segment is attributed to the rising concerns regarding water scarcity, declining water quality, rising expenses associated with water supply, and the growing digitalization facilitated by advanced data analysis programs.
