Leading Water Treatment Companies in the World 2022 – Water Treatment Suppliers and Wastewater Companies

Water Treatment Suppliers and Wastewater Companies

Global Water Treatment Market Overview

Water treatment and wastewater management are key operations for municipalities and important processes for many industrial companies. According to recent analysis by Meticulous Research, the global water and wastewater treatment market is projected to pass $240 billion in value by 2027, growing at a CAGR of 6.7%. The industry hosts many billion-dollar companies, with some being pure play water treatment companies but many operating across several industries and business areas.

As populations continue to grow and urbanization increases around the world, demand is rising for reliable water sources and water treatment solutions. Governmental regulations around water quality and wastewater treatment are tightening in many regions, and countries with large populations such as the US, China, and India have high demand for sewage treatment. All of this is creating growth opportunities for water treatment companies in countries around the world.

Asia-Pacific is the leading region of the global water treatment market, followed by North America. The growing population and developing infrastructure in many Asia-Pacific countries is helping drive demand for water infrastructure and residential water treatment. China is expected to lead the market in this region over the coming years, due to its large population and extensive industrial activities.

The COVID-19 pandemic is countering some of the global market’s growth in 2022, however, and this will likely continue into 2021 as well. While municipal water and wastewater treatment operations will remain of high importance, many industrial users of water have significantly reduced their activities, resulting in less demand for water treatment solutions in that sector. The water and sewage industry isn’t without its challenges, however, facing the common setbacks of socially distanced operations and supply chain disruptions.

The IoT has made its way into water treatment companies’ products and solutions, allowing for smart water treatment systems that gather and analyze data in order to improve water management efficiency for cities and businesses. Smart water treatment technology can link multiple systems and players, including water sources, treatment plants, distribution systems, and customers, monitoring the status of resources and equipment and allowing operators to adapt and adjust as necessary.

Top Water Treatment Companies in the World in 2022

These companies are world leaders in the water and wastewater treatment market, many earning billions in revenue every year. Some, such as BASF or DuPont, have multiple revenue streams across numerous industries, allowing them to be more adaptable in the face of setbacks in a particular industry. However, pure play water treatment companies have the advantage of specialization, concentrating their expertise into a few select areas. Regardless of their number of business areas, these water treatment companies are all industry leaders with operations in many countries around the world.
