Growth Factors in the Water and Wastewater Treatment Market

• Increased water scarcity: water and wastewater treatment is highly essential due to the growing water scarcity of drinkable and usable water. Without the treatment plants, water will not be treated for use again for different purposes.
• Rising population: Every year, the population rises significantly, which has led to the growing demand for water for drinking, household purposes, and other purposes. In the future, as the population grows, more and more water will be needed to fulfill the growing demand.
• Rising industrialization: almost every industry requires water for different procedures. Industrialization has led to a vast amount of water consumption. As industrialization grows, the demand for water also increases.
• The rise in agriculture: A large population requires a large amount of food, due to which a very big portion of water is used in agriculture. With the rise in technologies like hydroponics and vertical farming, the consumption of water has increased even further.

Opportunities in the Water and Wastewater Treatment Market

• In January 2025, in order to help the Regional Water Company Prishtina improve sewage treatment through the construction of two wastewater treatment plants and network expansion, the European Bank for Reconstruction and Development (EBRD) is offering Kosovo's Ministry of Finance, Labor, and Transfers a sovereign loan of up to €25 million.
• In December 2024, with the completion of its most recent funding round, VVater, a next-generation water treatment company dedicated to providing sustainable, clean water access solutions, announced that it had received substantial support from well-known investors, including venture capitalist Tim Draper, Dick Anderson of HPI, and two other well-known billionaire investors.
• In March 2024, with a total budget of US$10.5 million, the Global Green Growth Institute (GGGI) and the Department of Planning (DoP) of the Ministry of Planning and Investment (MPI) of Lao PDR, with funding from the Korea International Cooperation Agency (KOICA), have started a project called "Scaling Out Sustainable Solid Waste and Wastewater Management to Improve Public Health and Environment in Lao PDR."

Asia Pacific Water and Wastewater Treatment Market Size to Hit USD 282.80 Bn by 2034

The Asia Pacific water and wastewater treatment market size was valued at USD 125.60 billion in 2024 and is expected to hit approximately USD 282.80 billion by 2034. The APAC market is projected to grow at a notable CAGR of 8.60% from 2024 to 2034. Asia Pacific Water and Wastewater Treatment Market holds a significant share of 36.10% in 2024.

Rising Industrialization is Driving the Asia Pacific

Asia Pacific held the largest share of the water and wastewater treatment market in 2024. There is a significant need for water and wastewater treatment solutions due to the fast urbanization, industrialization, and population increase in nations like China, India, and Southeast Asia. The area is seeing large expenditures in the construction of infrastructure, government programs aimed at protecting the environment and conserving water, and a growing understanding of the significance of sustainable water management techniques.

The Asia Pacific water and wastewater treatment market is expanding due to the rise in industrial activity, the requirement to comply with strict regulations, and the need to enhance the quality of the water.

• In April 2024, Watertech China 2024, the largest one-stop global water treatment sourcing event, offers possibilities to progress enterprises in China and across the world for organizations who are leading the way in innovative solutions or eager to use the most recent technology advancements in water treatments. Watertech China 2024 is expected to transform the sector with the introduction of at least 300 new goods and services from well-known international firms.
• The largest worldwide sourcing event in the water treatment sector, the event is anticipated to draw an amazing 100,000 attendees and has an extensive roster of over 2,500 exhibitors.

India has water scarcity in several areas while having 18% of the world's population and only 4% of its water resources. India has launched a number of national programs to improve public health and the environment while also expanding basic infrastructure.

For instance, in March 2023, India is to invest about US$240 billion in the nation's water industry, according to Minister Jal Shakti Gajendra Singh Shekhawat, who made the announcement during the UN 2023 Water Conference. In addition, it is working to restore groundwater levels and is executing the biggest dam restoration operation in the world.

Stringent Regulations is Driving North America

North America is estimated to host a significantly growing water and wastewater treatment market during the forecast period. The area is known for its sophisticated infrastructure, strict environmental laws, and great awareness of water conservation and quality. The need to update outdated water infrastructure, deal with water shortage challenges, and guarantee regulatory compliance are some of the drivers driving the need for water and wastewater treatment systems in North America. The dominance of North America in the industry is further influenced by the existence of established market players, technical developments, and large R&D expenditures.

Wastewater treatment is one of the most popular methods of pollution control in the US. The nation has an extensive network of treatment facilities, pumping stations, and collection sewers. Sewers transport wastewater from residences, workplaces, and other industries to treatment facilities. In the U.S., there are more than 16,000 publicly owned water resource recovery facilities. To guarantee that modern and new facilities continue to safeguard the environment and public health, knowledgeable engineers and operators collaborate.

Water and Wastewater Treatment Market Segmentation Analysis
By Equipment Analysis
The membrane separation segment held the largest share of the water and wastewater treatment market in 2024. Pollutants, microorganisms, and harmful microbes may all be efficiently captured using membrane separation technology. High quality, stability, and safety are its benefits over traditional water treatment methods. The advancement of membrane separation technology has even been dubbed "the third industrial revolution" by experts.

The biological segment is estimated to grow at the fastest rate during the forecast period. Biological treatment is a contemporary method that uses microorganisms rather than chemicals to clean wastewater. Numerous biological wastewater treatment methods, including membrane bioreactors, trickling filters, and the traditional activated sludge process, can be utilized to eliminate a range of contaminants from wastewater.

By Process Analysis

The tertiary segment dominated the water and wastewater treatment market in 2024. A third, more complex, and demanding degree of therapy is added with tertiary care. Water that has undergone tertiary treatment can be sufficiently purified to be used again in water-intensive operations or even as drinking water. The secondary segment is expected to achieve the fastest CAGR during the forecast period. After the main phase, the secondary treatment phase further filters the water to eliminate more trash, making it an essential step in the wastewater treatment process.

By Application Analysis

The industrial segment gained the majority shares of the water and wastewater treatment market in 2024. Tons of water are used daily by industries for manufacturing and other purposes. The methods and systems used to treat water for industrial usage are known as industrial wastewater treatment solutions. By decreasing water usage and boosting water availability, water treatment in enterprises may contribute to sustainability. One of the main benefits of water treatment in industries is cost reduction.
