In line with the rising demand for wastewater treatment and adoption of Water Treatment Chemicals following are some of the key updates:

In 2025, Schneider Electric announced to launch of India’s largest water treatment plant construction in Bhandup, Mumbai. The company has been awarded the construction of a water treatment plant with a total processing capacity of 2,000 million liters per day.
In 2024, Veolia announced to inauguration of its first exchange regeneration plant with the integration of water recycling systems in China. The facility features state-of-the-art technology to efficiently recycle spent ion exchange resins, promoting resource optimization and sustainability in Changshu Economic and Technological Development Zone (CEDZ) in Jiangsu province with a total capacity of 60 kiloliters for mobile water services and 5 kiloliters per day for deionization.
Additionally, in 2025, the Water Ministry of the state of Delhi in India announced plans to double its desalination capacity from 220 million gallons per day.

Segments that transform the industry

Based on the type, the global water treatment chemicals market is segmented into organic coagulant, inorganic coagulant, flocculant, corrosion inhibitors, scale inhibitors, biocide & disinfectants, chelating agents, anti-foaming agents, PH adjusters & stabilizers, and others. Corrosion inhibitors have seen tremendous growth and development over the past few years due to their usefulness in industrial water systems such as cooling towers, boilers, and pipelines. This is primarily because these inhibitors prevent failure of expensive equipment and infrastructure through rust and corrosion, which eventually leads to very high maintenance costs. In addition, stricter environmental regulations coupled with continuous emphasis on sustainability push industries to invest in efficient corrosion control solutions, driving demand in the market even further. Advancements in green chemistry have also resulted in the development of more environmentally friendly corrosion inhibitors, which entice a higher range of end-users in many sectors such as oil & gas, power generation, chemical manufacturing, and even municipal water treatment. With the increase in industrialization, especially in developing regions, the demand for corrosion inhibitors will continue to be strong.

According to the report, the growing demand for chemically treated water in end-user industries across the globe has been identified to be a key driver for market growth. Some of how this impact has been felt include:

With the expansion of end-user industries as oil & gas, petrochemicals, paper & pulp, etc., the generation of wastewater has extensively grown, further promoting the need for chemical treatment. As the industries mentioned above generated a large amount of wastewater filled with chemicals and heavy particles, which are hazardous for the environment, the installation of wastewater treatment units is on the higher side.

Recently, many of the petrochemical, oil & gas plants have been announced to be constructed, which would be crucial for the further establishment of the wastewater treatment plant, leading to the future uptick in the demand for wastewater treatment chemicals. For instance,

Saudi Aramco and TotalEnergies have announced plans to construct the Amiral Petrochemical Complex in Saudi Arabia with a total investment of USD 11 billion. The construction of the unit started in the year 2023, while the construction is set to be finished by 2027.
A joint venture between Iraq’s Oil and Industry Ministries and Royal Dutch Shell has announced plans to construct the Nibras Petrochemical project in Iraq with a total cost of USD 8.5 billion. The project will have a production capacity of 1.8 million tons.
In 2025, VA TECH WABAG secured an order worth USD380 million from Al Haer Environmental Services Company towards Engineering, Procurement and Construction (EPC) of a 200 MLD Independent Sewage Treatment Plant (ISTP), including connections to outfall delivery facilities.

Considering the rapid advancement in the end-user industries, many companies are receiving orders for the construction of new wastewater treatment plants, which would fuel the demand for wastewater treatment chemicals across the globe.

According to the report, the impact of Water Treatment Chemicals has been identified to be high for the North America region. Some of how this impact has been felt include:

North America has held a sizable market share in the global water treatment market. Some of the key factors attributed to the growth are stringent government policies enforcing the end-user industries to chemically treat their wastewater before releasing it into the water sources. Additionally, with the growing population, many of the growing cities have also adopted waste treatment plants to provide potable water to the residents, further improving the demand for water treatment plants. Considering these changes, there is a surge in the demand for water treatment chemicals across the region. Additionally, the region is the home to some of the leading urbanized economies as the US and Canada, which have stressed the need to reduce water pollution through industries. In line with the growing demand for water treatment chemicals, there have been many updates that are anticipated to exhibit a sizable yield in the demand for water treatment chemicals. For instance,

In 2025, Canada’s federal government announced a major investment of USD 258 million to improve water and wastewater infrastructure across the country.
In 2025, El Paso Water received a total investment of USD 23.5 million for the construction of a water treatment plant in the city of El Paso, Texas, USA. The construction is set to be completed by the year 2028 and will provide 295 million liters of purified water per year.

With the rapid advancement in the field of water purification plants across the region, the market for water treatment chemicals is further anticipated to rise during the forecasted years 2025-2033.
