South America Data Center Water Treatment and Recycling Market Size & Share Analysis - Growth Trends and Forecast (2027 - 2032)

Market Trends and Insights

AI-Ready Data Center Expansion Multiplies Per-Facility Water Treatment Loads

GPU-dense AI racks produce thermal loads of 50-150 kW per rack, compared with 5-15 kW for conventional servers. This change increases the need for water-based cooling and raises treatment capacity requirements at each campus. South America data center water treatment and recycling market demand therefore rises with the number and size of AI deployments rather than with server counts alone. New AI campuses increasingly require reverse osmosis, electrodeionization, and monitoring systems at commissioning instead of adding them later. Colombia’s data center pipeline includes construction projects that will require purpose-built water infrastructure as capacity expands. This favors suppliers that can design complete treatment systems for large facilities.^[1]

Rising Adoption of Liquid-Cooled AI Racks Redefines Water Quality Requirements

Direct liquid cooling can capture up to 95% of server heat and reduce evaporative losses by 90% compared with legacy cooling towers. Closed-loop circuits are sensitive to corrosion, scaling, and biological contamination, so they require continuous treatment and monitoring. A water-quality excursion can damage high-value server components, making reliable chemistry control important to operators. Ecolab’s 3D TRASAR technology illustrates the use of automated monitoring and dosing for direct-to-chip cooling applications. A 2025 study found that resin-wafer electrodeionization can support zero-liquid-discharge treatment of cooling-tower blowdown with energy use of 0.057-0.537 kWh/m³. These conditions increase the demand for treatment trains that provide consistent low-conductivity water.^[2]

Hyperscale and Colocation Campus Expansion Concentrates Treatment Procurement

Hyperscale construction is concentrating water-treatment purchasing in a smaller number of larger facilities. ODATA committed USD 1.3 billion to the DC BG02 and DC BG03 campuses near Bogotá, which are planned to provide 144 MW of combined capacity. Scala’s Barueri campus is designed for 600 MW of eventual IT capacity. Brazilian industry research states that a closed-loop campus requires 23,000 liters of water per installed MW. Ascenty had 26 data centers operating and 12 under construction across South America in 2026. These projects favor suppliers that can provide long-duration equipment, chemicals, monitoring, and service contracts.^[3]

Increasing Water-Efficiency Requirements in Data Center Projects Drive Treatment Investment

Brazil enacted REDATA in September 2026 and tied federal tax incentives to a Water Usage Effectiveness index at or below 0.05 L/kWh. This requirement makes closed-loop cooling, water monitoring, blowdown recovery, and advanced pretreatment more important for eligible projects. The threshold is tighter than the 0.15-0.30 L/kWh range reported by leading global hyperscalers in 2025. Colombia’s National AI Policy also supports data center development that uses water-efficient technologies. Water-quality monitoring and control systems benefit because compliance requires measured and verifiable consumption data. The South America data center water treatment and recycling market consequently has a stronger link between environmental compliance and equipment procurement.

Drought-Related Water Allocation Restrictions Introduce Supply and Permitting Risk

Multi-year drought conditions in Chile and Peru are limiting cooling-water availability in important data center locations. Facilities in stressed basins face periodic allocation reviews under Chile’s Water Code. The legal process makes site selection, community engagement, and water planning more consequential for new developments. Regulatory uncertainty can extend project timelines and delay water-treatment investment even when scarcity creates a need for advanced treatment. A planned USD 200 million facility in Santiago faced a court-mandated redesign and eventual permit withdrawal. Water scarcity can therefore raise demand for recycling while slowing projects that would purchase those systems.

High Capital Cost of Advanced Reuse and Zero-Liquid-Discharge Systems Limits Adoption Below Hyperscale Scale

Zero-liquid-discharge systems combine membrane bioreactors, high-recovery reverse osmosis, and electrodeionization. Their equipment, engineering, and commissioning requirements can exceed the budgets of sites below 20 MW of IT capacity. Membrane-based ZLD can reduce energy demand by 50% and operating costs by 30% compared with thermal ZLD alternatives. Veolia’s Vitória Water Reclamation Station became viable through a partnership between an industrial consortium and a municipal sanitation authority. This model can support large campuses but is less accessible to smaller enterprise and colocation sites. The result is a two-tier pattern in which hyperscale operators adopt advanced reuse first and smaller facilities retain basic filtration and softening.

South America Data Center Water Treatment and Recycling Market Segment Analysis

Reverse osmosis held 23.98% of the South America data center water treatment and recycling market share in 2026. It is the main demineralization option because it can treat groundwater, municipal water, and pretreated reclaimed water before downstream polishing. Filtration and ultrafiltration protect membranes, while ion exchange and softening manage hardness and silica in conventional circuits. Chemical treatment and disinfection control microbial risks in warm and humid settings. These systems form the core treatment train for cooling-water preparation.

Electrodeionization is projected to expand at an 11.34% CAGR through 2032. Liquid-cooled AI racks require product water below 10 μS/cm without chemical regeneration. A 2025 peer-reviewed study reported advanced EDI systems can produce water at up to 18 MΩ·cm resistivity with 0.1-0.3 kWh/m³ of energy use. QUA Group launched its FEDI GIGA system in August 2025 with product-water resistivity up to 17 MΩ·cm. The technology supports chemical-free polishing for direct liquid cooling and zero-liquid-discharge applications.

Municipal water held 32.16% of the South America data center water treatment and recycling market size in 2026. It remains the main source in São Paulo, Bogotá, and Santiago, where potable-water networks and industrial allocation arrangements are established. Groundwater is planned for selected southern Brazilian projects using closed heat-exchange systems. Surface water is secondary because drought periods can limit abstraction. Industrial recycled water and other alternatives remain early-stage options.

Reclaimed municipal wastewater is expected to expand at an 11.47% CAGR through 2032. Operators use it to reduce potable-water dependence and improve Water Usage Effectiveness performance. Sabesp signed a 2026 agreement to provide 11,000 m³ each month to a hyperscale facility in Barueri, with a planned direct pipeline connection. Brazil uses less than 1% of its water consumption through reuse despite its treatment infrastructure potential. Utility contracts could make reclaimed supply a stronger site-selection factor.

Cooling tower makeup water accounted for 27.28% of the South America data center water treatment and recycling market size in 2026. Evaporative cooling remains common at operating facilities across the region. The application needs coagulation, filtration, softening, and biocide dosing to manage scale, corrosion, and microbial activity. Chilled-water and closed-loop systems are gaining importance with direct liquid cooling. Wastewater treatment is subject to environmental discharge requirements in Brazil and Colombia.

Water recycling and reuse is projected to advance at an 11.88% CAGR through 2032. High-recovery treatment can return cooling-tower blowdown to service instead of discharging it. ODATA stated that its South American campuses use closed-loop systems without evaporative towers to reduce cooling-water use. Zero-liquid-discharge and concentrate management command specialized work because of demanding operations and regulations. The market is shifting toward treatment designs that recover water within the site. 

Water treatment equipment held 40.77% share in 2026. Reverse-osmosis skids, membrane housings, electrodeionization modules, and filtration vessels account for a large portion of installation costs. Large plants require multiple membrane vessels and chemical-dosing units before operations begin. Chemicals remain important because liquid cooling needs specialized corrosion and biological control. Operation and maintenance services support long-term supplier relationships and recurring revenue.

Water quality monitoring and control systems are expected to expand at an 11.73% CAGR through 2032. REDATA requires measurable water-efficiency data, and real-time monitoring helps facilities manage chemistry in liquid-cooled equipment. Ecolab reports that its connected monitoring portfolio includes more than 100,000 devices globally. Engineering remains important where alternative feed water has variable quality. ISO 46001:2019 is increasingly relevant in procurement requirements.

Hyperscale facilities held a 46.97% share in 2026 and are projected to expand at an 11.94% CAGR through 2032. This is the only size category where the largest segment is also the fastest-growing. Their scale increases water-quality risk and water-recovery opportunity. Brazilian industry research estimates a closed-loop hyperscale campus requires 23,000 liters of water per installed MW. Large projects often justify full-cycle treatment and continuous monitoring systems.

Large data centers in the 10-30 MW range need similar functions but often select modular systems to limit initial spending. Medium and small facilities more commonly use softening and basic filtration and install ZLD only when local water restrictions require it. AI workloads are concentrating in larger campuses, concentrating procurement in fewer contracts. Global providers with engineering, chemicals, equipment, and O&M capabilities have an advantage. Research notes that data center water use can create ecological risk from heated discharge and salinity in blowdown.

Cloud service providers held a 45.23% share in 2026. AWS, Microsoft Azure, and Google Cloud anchor major development in Brazil, Chile, and Colombia. Their water stewardship commitments influence supplier specifications and site selection decisions. These commitments also encourage the adoption of water-efficient cooling and infrastructure solutions. Amazon has pledged water positivity in its direct operations by 2030. Google reported that 87% of its global freshwater withdrawals in 2025 came from low- to medium-stress sources.

Cloud service providers are expected to expand at an 11.86% CAGR through 2032. Veolia and Amazon announced a 2026 collaboration to develop modular reclaimed-water treatment systems. Equinix’s ST2 expansion in Santiago uses liquid cooling that recycles 90% of the water used. Enterprise and edge sites generally rely on standard softening and biocide programs. Their expansion in less-developed municipal markets creates a role for regional service providers.
