Australia And New Zealand Water Treatment Chemicals Market - Size, Share Outlook, Growth Analysis Report and Forecast Trends (2026-2035)

Market Overview

The Australia and New Zealand water treatment chemicals market is driven by sustained municipal water investment, tightening drinking water and contaminant regulation, and reuse of process and cooling water in mining, power generation, and oil and gas. Utilities and industrial operators treat larger volumes of drinking water, wastewater, and recycled water each year, and every new or upgraded plant lifts demand for coagulants, disinfectants, and corrosion and scale control chemistry.

Three forces are shaping the market: PFAS and drinking water quality regulation, multi-year utility capital programmes in both Australia and New Zealand, and the growth of industrial and mining water reuse in drier states. Domestic manufacturing and distribution, led by Melbourne-based Ixom and Orica, sits alongside imported specialty chemistry from global water treatment suppliers.

In June 2025, the National Health and Medical Research Council updated the Australian Drinking Water Guidelines for PFAS, tightening the values for PFOA to 200 nanograms per litre and PFOS to 8 nanograms per litre. The change pushes utilities toward additional treatment and monitoring and points to sustained procurement of coagulants, biocides, and specialty chemicals through the forecast period.

Key Market Trends and Insights

• Tighter PFAS regulation: The June 2025 update to the Australian Drinking Water Guidelines lowered PFAS limits, driving utilities to add treatment steps and lifting demand for coagulants and specialty chemistry.
• Utility capital programmes: Large multi-year investment plans, including Watercare's NZD 13.8 billion Auckland programme, sustain long-run procurement of drinking water and wastewater chemicals.
• Industrial and mining reuse: Mining, power, and oil and gas operators in Western Australia and Queensland are expanding water reuse, increasing use of biocides, scale inhibitors, and corrosion inhibitors.
• National PFAS restrictions: Australia's IChEMS Schedule 7 ban on PFOS, PFOA, and PFHxS from July 2025 is reshaping treatment and contaminated water management across the region.
• Desalination and drought resilience: Utilities in New South Wales and Victoria are investing in desalination and reliability upgrades, broadening demand for membrane antiscalants and pre-treatment chemistry.

Australia And New Zealand Water Treatment Chemicals Market Size and Forecast

The Australia and New Zealand water treatment chemicals market expands across the forecast period as tighter water quality rules, large utility investment, and industrial water reuse lift chemical demand. Growth is led by municipal upgrades and tightening PFAS and discharge regulation, supported by rising mining, oil and gas, and power-sector water management across drier regions. Major utility capital programmes in both countries underpin durable procurement of treatment chemicals through the period.

Key Takeaways: Australia And New Zealand Water Treatment Chemicals Market

Regulation and Utility Investment Anchor Steady Growth

The market stands at AUD 1,120.40 million in 2025 and is on track to reach AUD 1,895.74 million by 2035 at a 5.4% CAGR. Growth is anchored by tightening drinking water regulation and multi-year utility capital programmes in both countries, which convert compliance and renewal needs into steady chemical procurement. Suppliers can secure long-term demand by aligning products with PFAS treatment and utility upgrade projects.

Coagulants Lead Volume While Biocides Grow Fastest

Coagulants and flocculants account for the largest share, reflecting their heavy use in municipal drinking water and wastewater clarification, while biocides and disinfectants record the highest growth as utilities and industrial operators tighten disinfection and manage reuse water. Suppliers can capture value by offering high-volume coagulant chemistry alongside specialty biocides for cooling, reuse, and compliance-driven applications, pairing dependable municipal supply with higher-margin specialty products across both countries.

Mining and Industrial Reuse Signal Durable Specialty Demand

Water reuse in mining, power, and oil and gas across Western Australia and Queensland points to a durable pipeline of demand for scale inhibitors, corrosion inhibitors, and biocides. Companies can expand share by developing site-specific programmes and technical service that match the harsh water chemistry of industrial and mining operations in drier regions, while supporting utilities that increasingly recycle water to build long-term resilience against drought and supply constraints.
