Taiwan Industrial Wastewater Treatment Market Forecast to Reach USD 20.26 Billion by 2032, Growing at a CAGR of 7.20% During 2026–2032

The Taiwan industrial wastewater treatment market was valued at USD 12.45 billion in 2025 and is projected to grow from USD 13.35 billion in 2026 to USD 20.26 billion by 2032, registering a CAGR of 7.20% during the 2026–2032 forecast period. This growth is anchored in expanding industrial water reuse infrastructure and increasingly stringent discharge standards across Taiwan's high water-consuming manufacturing sectors, positioning the country as a critical hub for advanced industrial wastewater treatment technologies.

Rapid semiconductor fabrication expansion is intensifying demand for industrial wastewater reclamation systems. TSMC's Water Reclamation Plant at the Southern Taiwan Science Park, together with its Yongkang facility, supplies a combined 62,500 cubic meters of reclaimed water daily. Furthermore, Taiwan's broader water reuse strategy targets 334,000 cubic meters per day of combined reclaimed water capacity by 2026, backed by approximately USD 573 million in investment, alongside a Ciaotou project supported by USD 169 million in investment.

The Taiwan industrial wastewater treatment market remains moderately fragmented, with the top five companies — CTCI Corporation, ECOVE Environment Corporation, Forest Water Environmental Engineering Co., Ltd., HDEC Corporation, and WaterPark Environment Corp. (Gradiant Group) — collectively accounting for approximately 45% share. As a result, continued semiconductor investment and tightening water pollution control fees are expected to sustain long-term demand for advanced industrial wastewater treatment and resource-recovery solutions across Taiwan.
