South America Dewatering Equipment Market Outlook, 2031

Market Drivers

• Brazilian Sanitation Investment Cycle: The New Sanitation Legal Framework (Lei 14.026/2020) targets universal sewage collection by 2033, creating a sustained cycle of tender-based procurement for thickening, dewatering, and drying systems. The investment requirement ranges from R$ 550 billion to R$ 816 billion, driving concession contracts worth tens of billions of reais across the country. This regulatory certainty catalyses municipal utilities to replace aging drying beds and belt presses with high-efficiency centrifuges and screw presses capable of meeting CONAMA 498/2020 biosolid standards while reducing sludge volumes by up to 80%.
• Chilean Mining Water Scarcity Mandates: Chile's copper mining industry faces acute water scarcity in the Atacama Desert, with 17 of the country's 24 desalination plants now serving the mining sector and an estimated 71.5% of mining water projected to come from seawater by 2034. The transition to dry-stack tailings, as exemplified by Anglo American's Los Bronces mine, enables water recovery rates above 80% and reduces water consumption by 54% to 72%. SERNAGEOMIN's regulatory framework mandates comprehensive tailings management plans, driving adoption of high-capacity thickeners, filter presses, and centrifuges for water recovery and safe tailings disposal.

Market Challenges

• Regulatory Fragmentation Across Jurisdictions: South America's dewatering equipment market operates under a fragmented regulatory landscape, with each country imposing different technical standards, discharge limits, and compliance requirements. Brazil's CONAMA 498/2020 establishes biosolid quality thresholds for soil application, while Chile's Decreto Supremo N°248/2006 governs tailings deposit design and closure. Peru's ANA requires special authorizations for dewatering (AEOFN) under the Water Resources Law, while Argentina's ACUMAR enforces detailed technical specifications for dewatering equipment including flocculant use, humidity of dewatered sludge, and batch duration. Navigating this complexity requires specialised expertise, creating barriers for new entrants and favouring established suppliers with proven compliance track records.
• Capital Cost Barriers and Import Dependence: High capital costs for imported, high-efficiency dewatering trains exceeding USD 350,000 to 700,000 per unit represent a significant barrier for small-to-medium municipalities and local contractors. Import duties, taxes, and logistics surcharges add an estimated 25-35% to landed equipment prices, making South America a relatively high-cost market for imported systems. The region's import dependence for advanced dewatering equipment remains at approximately 52.8%, with high-end intelligent pump imports accounting for 79.3% of the total. Brazil and Chile have begun implementing import substitution incentive policies, with local content requirements expected to reduce import share to below 45% by 2030.

Market Trends

• Dry Stack Tailings Adoption: The transition from conventional wet tailings dams to dry-stack and filtered tailings is accelerating across South America's mining sector. Chile's Codelco has awarded TAKRAF a contract for seven DELKOR High-Density Thickeners and shear thinning technology for what will be the world's largest thickened tailings project. Anglo American's Los Bronces mine has implemented Hydraulic Dewerated Stacking (HDS) alongside Coarse Particle Recovery (CPR) technology, producing a free-draining sand byproduct and recovering over 80% of water from tailings for reuse in the mining process. This trend is driving demand for high-capacity filter presses, centrifuges, and thickeners capable of producing stackable tailings with moisture content below 20%.
• Decentralised Treatment and Resource Recovery: The South American market is witnessing a strategic shift toward decentralised treatment and resource recovery, driven by the need for cost-effective and sustainable solutions. In Brazil, the Teknobag-Draimad system has been permanently installed at the Nova Divineia WWTP, achieving sludge solids content of 15% within 10 days and meeting Class B biosolid requirements under CONAMA 498/2020. The system's filter bag achieved over 99.9% efficiency in retaining sludge solids, producing clarified water with Chemical Oxygen Demand below 90 mg/L. This compact, automated, and pressurised system requires minimal space and offers operational simplicity and lower implementation and maintenance costs compared to traditional methods.
