Key Market Dynamics
Drivers: Urbanization, Population Growth, and Regulatory Pressure
The demand for efficient water and wastewater treatment systems is on the rise due to fast-paced urbanization and global population expansion. In 2022, the World Health Organization noted that 4.6 billion people had access to safely managed sanitation services, highlighting the scale of reliance on sanitation infrastructure. Simultaneously, over 2.7 billion people use private facilities connected to sewer networks. This widespread usage is increasing the need for robust treatment technologies to ensure water safety and sustainability.
Rapid industrialization is another factor fueling market demand. Industries depend heavily on water for processes such as cooling, cleaning, and waste disposal. Due to resource constraints and environmental awareness, many businesses are exploring strategies to minimize water consumption and maximize wastewater reuse. Governmental regulations have become more stringent globally, compelling industries and municipalities to adopt more sophisticated and compliant water treatment systems.
Challenge: Scarcity of Freshwater Resources
Freshwater resources are becoming increasingly scarce. By 2045, the global water demand could outpace supply by nearly 40%. As of March 2023, around 2 billion people still lack access to safe drinking water, a crisis that is worsening with urbanization and pollution. This scarcity is encouraging investment in wastewater reuse and the development of treatment facilities that can reclaim water from industrial and municipal waste streams.
For instance, LANXESS AG, a chemical manufacturing company in Germany, invested approximately USD 13 million in a new wastewater treatment plant in Belgium, which is capable of processing around 260,000 liters of wastewater per hour. Rising pollution and the resulting reduction in usable freshwater further emphasize the urgency for scalable and reliable water treatment infrastructure.
Opportunities: Technological Innovation and Energy Efficiency
Water and wastewater treatment processes are energy-intensive, particularly in municipalities. In fact, wastewater treatment plants are the third-largest energy consumers within municipal operations, contributing up to 35% of a city's energy use. To address both cost and environmental concerns, operators are increasingly focusing on energy efficiency.
Advancements in smart technologies and energy-efficient systems present promising growth avenues. Innovations such as membrane bioreactors, ultraviolet disinfection systems, and energy recovery technologies are being implemented to reduce operational expenses and carbon footprints. Integration of digital tools such as SCADA (Supervisory Control and Data Acquisition) systems helps in pump optimization and predictive maintenance.
Rising Demand for Decentralized and Smart Water Systems
Decentralized treatment systems offer a scalable alternative to traditional centralized infrastructure, especially in remote or underdeveloped areas. These systems are gaining traction due to their cost-effectiveness and adaptability. At the same time, the incorporation of IoT sensors, AI-based analytics, and cloud platforms is transforming water resource management, enabling real-time monitoring and smart decision-making.
Smart water solutions allow municipalities and industries to optimize operations, track water quality, and ensure compliance with environmental norms. These technological advancements are especially relevant in regions struggling with outdated infrastructure and regulatory challenges.
Segment Analysis
By Type: Wastewater Treatment Takes the Lead
In 2025, the wastewater treatment segment is expected to dominate, accounting for about 63% of the market. The dominance of this segment stems from growing awareness of waterborne diseases, the need to improve public health, and expanding industrial zones that require efficient wastewater processing. Additionally, advancements in treatment methods, environmental policies, and recycling initiatives continue to drive this segment forward at the highest projected growth rate during the forecast period.

By Offering: Operation & Maintenance Services Hold the Largest Share
The market is segmented into treatment technologies, chemicals, automation, engineering services, and operation & maintenance (O&M) services. Among these, O&M services are projected to hold the largest share in 2025—around 39.5%. These services are critical for ensuring consistent water quality, managing complex treatment facilities, and complying with regulatory standards. As facilities become more technologically advanced, the need for expert O&M services is expected to grow significantly.
Conversely, the process control and automation segment is forecasted to grow at the highest CAGR. Automation is becoming essential in response to water scarcity, rising operational costs, and the need for data-driven water management systems.
By Application: Municipal Sector to Dominate
The municipal segment is anticipated to account for 69% of the total market in 2025. This dominance is attributed to increasing urbanization, which places pressure on municipal authorities to deliver clean water and treat wastewater effectively. Rising global populations, improvements in treatment processes, and growing investment in public infrastructure contribute to the robust growth of this segment.
Meanwhile, the industrial segment is expected to record the fastest growth during the forecast period. Various industries—including chemicals, power generation, pharmaceuticals, and food & beverages—are adopting advanced treatment solutions to meet strict discharge standards and reuse water. With rising costs of freshwater and tighter environmental oversight, industries are investing heavily in solutions such as membrane filtration, zero-liquid discharge systems, and real-time monitoring technologies.
Geographical Trends
Asia-Pacific to Lead the Market
In 2025, the Asia-Pacific region is projected to hold the largest market share at over 42.8%. Rapid urban development, increased demand for potable water, and technological advances in countries such as China, India, and Vietnam are driving the regional market. In addition, countries like Singapore are pioneering water recycling technologies and integrated water management systems, further setting the stage for regional leadership.
Foreign investments and cross-border collaborations are also contributing to Asia-Pacific’s growth, as international organizations partner with local entities to deploy efficient treatment technologies. The region is expected to maintain the highest CAGR during the forecast period, fueled by environmental initiatives, government funding, and growing public-private partnerships.
