Growing Demand for Chemically Treated Water in End-Use Industries:

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.

Latest Trends in the Water Treatment Chemicals Market

Adoption of Eco-Friendly and Sustainable Chemicals:

As governments across the globe are becoming more environmentally conscious, the shift from synthetic chemicals for wastewater treatment is being observed. Many of the companies are focusing on the use of bio-based chemicals for water treatment. These chemicals are easily biodegradable and reduce the harmful impact on the ecosystem. In line with this, many of the wastewater treatment chemical producers have announced the launch of bio-based chemicals.

In 2024, Aquacycl, an industrial wastewater treatment solutions provider, announced the launch of its patented SulfideFix chemical. It utilizes natural sulfate-reducing bacteria to eliminate up to 99%.

In line with this, many of the other key companies are also launching their bio-based chemicals for wastewater treatment. This is anticipated to be a key trend among the manufacturers, which would be conducive for the market growth in the forecasted years, i.e., 2025-2033.

Integration of Digital Technologies and Automation:

Digital technologies and automation are rapidly modernizing the water treatment chemicals market. With the combination of the technologies, real-time data collection and analysis can facilitate more accurate chemical dosing and early detection of system abnormalities beyond predicting maintenance. This increases operational efficiency while reducing chemical wastage and lowering operational costs. Automation also fosters consistent quality of treatment as it minimizes human errors and enables process control. Power generation and pharmaceuticals, along with municipalities that treat water, are the prime users of these smart systems because of their need for efficient performance, regulatory compliance, and environmentally friendly options. The very digital platforms allow remote management, which is of growing importance in the post-pandemic world. With the increasing problems of water scarcity and pollution, digital innovation remains a major enabler of smarter, safer, and sustainable water management.

Regional Market Growth

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.
