Global Dewatering Equipment Market Projected to Reach USD 13.55 Billion by 2031, Driven by Rising Wastewater Treatment, Mining, Construction and Infrastructure Development Demand from 2026–2031
The global dewatering equipment market stands at a pivotal inflection point, shaped by an unprecedented convergence of regulatory mandates, infrastructure investment, and the accelerating transition toward circular economy principles in water management. The United Nations SDG 6.3.1 progress report confirms that globally, an estimated 56% of household wastewater flows were safely treated in 2024, with 42% of household wastewater not safely treated before discharge, leading to an estimated 113 billion cubic metres of household wastewater being released to the environment with inadequate or no treatment. The U.S. Environmental Protection Agency's Part 503 regulations, promulgated under Section 405(d) of the Clean Water Act, establish comprehensive standards for sewage sludge applied to land, managed through surface disposal, or incinerated, creating a compliance-driven procurement cycle for advanced dewatering technologies across the nation's 16,000 publicly owned treatment works. The European Union's recast Urban Wastewater Treatment Directive 2024/3019, published in November 2024, mandates Member States to transpose its provisions by June 2027, introducing stricter phosphorus and nitrogen discharge limits, extending coverage to municipalities from 2,000 to 1,000 inhabitants, and establishing a phosphorus reuse and recycling framework to be fixed by January 2028. The International Council on Mining and Metals' 2025 Tailings Progress Report confirms that 67% of the 836 tailings storage facilities operated by its members have achieved full conformance with the Global Industry Standard on Tailings Management, driving adoption of dry-stack tailings and high-capacity filtration systems across the global mining sector.
According to the research report "Global Dewatering Equipment Market Outlook, 2031," published by Bonafide Research, the Global Dewatering Equipment market was valued at more than USD 8.34 Billion in 2025, and expected to reach a market size of more than USD 13.55 Billion by 2031 with the CAGR of 8.65% from 2026-2031. Veolia Water Technologies, Alfa Laval AB, ANDRITZ AG, SUEZ Water Technologies & Solutions, and Xylem Inc. are key players, with Veolia serving municipal and industrial customers in more than 130 countries. SUEZ has been awarded the sludge dewatering contract for the relocation of the Sha Tin Sewage Treatment Works to caverns by the Hong Kong Drainage Services Department, designing and supplying equipment for what will be Asia's largest cavern-based sewage treatment plant. Alfa Laval has won a contract with Singapore's Public Utilities Board (PUB) to overhaul the Kranji Water Reclamation Plant, delivering innovative treatment technology to enhance sludge dewatering efficiency. In South Korea, ROYAL Precision Industry has established itself as a dominant domestic manufacturer, with its decanter centrifuge systems occupying 70% of the Korean sludge treatment market and operating at over 1,000 sites globally. The China General Machinery Industry Association's Separation Machinery Branch, representing 34 large-scale member enterprises, reported total output value of 13.33 billion yuan in 2023, a 5.1% year-on-year increase, with sales revenue of 11.8 billion yuan growing 14.6% and export value of 520 million yuan growing 18.2%. Entry barriers remain high due to varying certification requirements across regions, including China Compulsory Certification (CCC), Indian BIS marks, and Japan's JIS standards, which create duplication costs estimated at 5-10% of total procurement budgets for cross-border buyers.
The continuous generation of wastewater and industrial sludge, coupled with increasingly stringent environmental regulations, makes sludge and slurry dewatering the largest equipment category in the global dewatering equipment market. The United Nations SDG 6.3.1 progress report confirms that globally, an estimated 56% of household wastewater flows were safely treated in 2024, with 42% of household wastewater not safely treated before discharge, leading to an estimated 113 billion cubic metres of household wastewater being released to the environment with inadequate or no treatment. The U.S. EPA's Part 503 regulations establish comprehensive standards for sewage sludge management, requiring facilities that dewater sewage sludge to comply with pollutant limits and management practices. China's MOHURD, alongside the NDRC and MEE, set a binding target of a 90 percent harmless disposal rate for municipal sludge nationally by 2025, mandating the addition of no less than 20,000 tonnes per day of disposal capacity. The EU's Urban Wastewater Treatment Directive 2024/3019 requires Member States to upgrade treatment infrastructure by June 2027, extending coverage to municipalities with 1,000 or more inhabitants. The ICMM's 2025 Tailings Progress Report confirms that 67% of member tailings facilities have achieved full conformance with GISTM, driving adoption of dry-stack tailings and high-capacity filtration systems.
Centrifuges dominate the global market due to their high throughput, compact footprint, and ability to handle varying sludge characteristics, making them the preferred technology for large municipal and industrial operations. ROYAL Precision Industry has established itself as a dominant domestic manufacturer in South Korea, with its decanter centrifuge systems occupying 70% of the Korean sludge treatment market and operating at over 1,000 sites globally. Alfa Laval has won a contract with Singapore's Public Utilities Board to overhaul the Kranji Water Reclamation Plant, delivering innovative treatment technology to enhance sludge dewatering efficiency. In Egypt, the colossal West Delta Wastewater Treatment Plant employs six GEA biosolids Decanter prime 8000 units, a clear indicator of the scale of demand for high-capacity dewatering solutions. Pieralisi has over 1,800 operational centrifuge units deployed across Spanish wastewater treatment plants, confirming the technology's deep penetration in the region's municipal sector. The China General Machinery Industry Association's Separation Machinery Branch, representing 34 large-scale member enterprises, reported total output value of 13.33 billion yuan in 2023, a 5.1% year-on-year increase, with sales revenue of 11.8 billion yuan growing 14.6% and export value of 520 million yuan growing 18.2%. Centrifuge manufacturers are integrating IoT sensors and data analytics for predictive maintenance and polymer optimisation, offering aftermarket services that enhance lifecycle value. The technology's dominance is reinforced by its deployment across Brazil's largest sanitation projects, where CONAMA 498/2020 biosolid standards require consistent dry solids content that centrifuges reliably achieve.
The oil and gas sector is the fastest-growing end-user for dewatering equipment, driven by massive volumes of produced water generated during hydrocarbon extraction, tightening environmental regulations on discharge, and the industry's transition toward water reuse and reinjection. The U.S. EPA currently limits the content of oil and grease in produced waters to 29 ppm with a maximum of 42 ppm, driving demand for separation and dewatering equipment. The Subsecretar?a de Recursos H?dricos in Neuqu?n Province, Argentina, formalised Decreto 792/2026 in June 2026, declaring water reuse, recovery, and recirculation in unconventional hydrocarbon operations as priority public policy, with a new water canon scheme incentivising reduced freshwater abstraction. The Gravita S.A.U. drilling sludge and cuttings treatment, dehydration, and reuse plant in A?elo, Neuqu?n, incorporates a vertical cutting dryer and decanter/tricanter for phase separation as part of a comprehensive treatment train. In the U.S., the EPA's 2022 Construction General Permit contains provisions requiring heightened inspection and stabilization requirements for sites discharging to certain sensitive waters, monitoring requirements for certain dewatering discharges, and requirements for discharges to waters impaired for polychlorinated biphenyls (PCBs). Hydraulic fracturing in shale plays generates substantial produced water volumes, with wells in the Northern Llanos Basin operating with water cuts exceeding 90%, driving adoption of relative permeability modifier treatments that have demonstrated up to 90% reduction in water permeabilities. The NDRC and Ministry of Commerce 2025 Encouraged Foreign Investment Catalogue specifically lists horizontal screw centrifuge dewatering machines under water pollution prevention equipment manufacturing, signalling policy support for advanced separation technology in the petroleum and petrochemical sectors.
