Future Outlook
The Vietnam Biological Wastewater Treatment Market is projected to increase from USD 302.1 million in 2025 to USD 524.1 million by 2031 . The historical CAGR of 8.4% during 2020-2025 reflected industrial recovery, urban project execution, environmental permitting, and higher demand for biological retrofits. Forecast growth accelerates to 9.6% during 2026-2031 as QCVN 40:2025/BTNMT expands the compliance addressable market, wastewater collection networks feed existing plants more effectively, and industrial customers move toward nutrient removal, reuse, and automated monitoring. Revenue growth will outpace treated-volume growth because advanced reactors and control packages increase project value per unit of capacity.
By 2031, biologically treated throughput is expected to reach 5.61 million m3 per day , compared with 3.50 million m3 per day in 2025 . The strongest expansion is expected in MBBR, IFAS, MBR, anaerobic digestion, and hybrid systems used by food processing, textiles, electronics, chemicals, hospitals, and dense urban catchments. Recurring O&M and performance optimization will gain share as public owners and industrial parks seek reliable compliance rather than asset-only delivery. Upside depends on tariff reform, project disbursement, and higher utilization of installed municipal capacity; downside remains concentrated in delayed sewer connections, fragmented provincial procurement, and weak cost recovery.
