IMARC Group, a leading global market research and management consulting firm, has published its latest market intelligence report on the Saudi Arabia water and wastewater treatment chemicals market. The Saudi Arabia water and wastewater treatment chemicals market size reached USD 830.1 Million in 2025. Looking forward, IMARC Group expects the market to reach USD 1,760.4 Million by 2034, exhibiting a growth rate (CAGR) of 8.71% during 2026-2034, driven by rising industrialization, expanding desalination infrastructure, stringent environmental regulations, growing municipal wastewater treatment demand, and the continued expansion of oil and gas, power, and petrochemical operations across the Kingdom.

The market is experiencing strong growth momentum as Saudi Arabia advances its national water strategy under Vision 2030, treating water security as a foundational pillar of industrial diversification and urban development. Saudi Arabia meets more than 60% of its municipal water demand through energy-intensive desalination, a reliance that has increased by around 6% over the last two decades, making chemical treatment an indispensable component of the national water supply chain. The government has set a determined goal of fully recycling treated wastewater in major cities, a target that is reshaping demand across coagulants, biocides, corrosion inhibitors, and specialty formulations used in municipal, industrial, and desalination applications.

How AI is Reshaping the Future of Saudi Arabia Water and Wastewater Treatment Chemicals Market?

• AI-Powered Dosing Optimization Across Desalination and Municipal Plants: Machine learning systems are being integrated into reverse osmosis and municipal treatment facilities to analyze real-time water quality parameters, enabling operators to fine-tune antiscalant, biocide, and coagulant dosing precisely, reducing chemical overuse while maintaining membrane efficiency at large-scale plants such as those operated by the Saudi Water Authority.
• Predictive Fouling and Scaling Detection for Reverse Osmosis Membranes: AI-driven sensor networks are enabling early detection of membrane fouling and scaling trends in desalination plants, allowing operators to adjust scale inhibitor and antifoaming agent application before efficiency losses occur, a critical capability given the Kingdom's position as the world's largest producer of desalinated water.
• AI-Enhanced Industrial Wastewater Process Control for Petrochemical Complexes: Petrochemical operators including those tied to Saudi Aramco and SABIC affiliated facilities are deploying AI-based process control systems to manage corrosion inhibitor and pH adjuster application across cooling and boiler water systems, reducing unplanned downtime and supporting compliance with strict wastewater discharge regulations in energy-intensive production environments.

Saudi Arabia Water and Wastewater Treatment Chemicals Market Trends and Drivers

Saudi Arabia's rapid industrialization, propelled by the expansion of petrochemicals, power generation, and manufacturing sectors, is a crucial factor driving demand for water and wastewater treatment chemicals. Industries consume large volumes of treated water for operations while complying with strict wastewater discharge regulations, and the petrochemical sector, dominated by companies such as Saudi Aramco and SABIC, relies on corrosion inhibitors, pH adjusters, and biocides to maintain process water quality. The growth of independent water and power plants is adding further demand for chemicals used to manage boiler feedwater, cooling systems, and wastewater treatment, while the shift toward wastewater recycling and zero liquid discharge systems is amplifying the use of advanced chemical treatments to improve process effectiveness.

Desalination infrastructure expansion remains a defining driver of the market. The Saudi Water Authority manages 33 desalination plants and more than 139 purification plants nationwide, with a daily production capacity of 7.5 million cubic meters, making it the world's largest single producer of desalinated water. Growing reliance on reverse osmosis technology has significantly increased demand for scale inhibitors, antifoaming agents, and biocides needed to maintain membrane efficiency and prevent fouling. Public-private partnership desalination projects, including plants at Rabigh, Shuaibah, and Jubail, continue to accelerate the need for specialized water treatment chemicals, reinforcing their critical role in operational longevity. Saudi Arabia's water sector as a whole has become a major contracting arena, with stakeholders awarding contracts worth close to USD 15 Billion in a single year, a figure that averaged closer to USD 6.5 Billion annually between earlier periods, according to industry tracking by MEED.

Municipal and industrial wastewater recycling initiatives are further reinforcing chemical demand across the Kingdom. Saudi Arabia's National Water Strategy targets desalinated water accounting for 90% of national urban supply, reducing dependence on non-renewable groundwater sources, while large-scale industrial wastewater treatment plants tied to petrochemical zones are being developed under long-term concession arrangements that require continuous chemical dosing for effluent treatment and closed-loop water reuse. The Northern and Central regions, anchored by Riyadh, are witnessing steady growth in agricultural and infrastructure-driven demand for disinfectants, coagulants, and corrosion inhibitors, while the Western Region, home to Jeddah and Mecca, continues to see strong hospitality and municipal-driven consumption of treatment chemicals.

Saudi Arabia Water and Wastewater Treatment Chemicals Industry Segmentation

The report has segmented the market into the following categories:

Breakup By Product Type:

• Coagulants and Flocculants
• Biocides
• Corrosion and Scale Inhibitor
• Defoamer
• PH Adjuster
• Others

Corrosion and scale inhibitors represent a critical product type segment, driven by their essential role in protecting desalination membranes, boiler systems, and industrial pipelines from mineral buildup and structural degradation, a function that is particularly vital given the aggressive water chemistry and high mineral content typical of Saudi Arabia's seawater desalination feedstock.

Breakup By Application:

• Cooling Water
• Boiler Water
• Membrane Water
• Municipal
• Others

Membrane water applications hold a significant share of the market, supported by the Kingdom's heavy reliance on reverse osmosis desalination technology, where antiscalants, biocides, and cleaning agents are essential to sustaining membrane performance and extending operational lifespan across the country's extensive desalination plant network.

Breakup By End User:

• Oil and Gas
• Power
• Mining
• Pulp and Paper
• Chemical and Fertilizer
• Pharmaceutical
• Municipal
• Textile
• Food and Beverages
• Others

The oil and gas segment commands a leading share among end users, reflecting the sector's massive water consumption for process cooling, steam generation, and effluent treatment, combined with strict regulatory compliance requirements that necessitate consistent use of corrosion inhibitors, biocides, and pH adjusters across refining and petrochemical operations.

Breakup By Region:

• Northern and Central Region
• Western Region
