South Korea ministry and Posco sign water-positive MOU to reuse cooling water, Sept 2026
On 21 September 2026, South Korea's Ministry of Climate, Environment and Energy said it will sign a 'water positive' cooperation MOU with Posco at the Posco Center in Seoul the following day. Posco will monitor cooling water in real time and apply membrane filtration so water previously discharged as wastewater can be reused, starting on five cooling towers next year and expanding to 20 towers by 2028. Korea Water Resources Corporation will verify the saved intake volumes as water restoration. For operators, the event signals demand for monitoring instrumentation, packaged membrane skids and a documented mass-balance protocol for cooling-water reuse retrofits.
SK hynix trims Korean fab water use by 170,000 t/day, targets 600 Mt saved by 2030
At Korea International Water Week 2026 in Daegu on 8 September 2026, SK hynix said its Korean fabs cut water use by an average 170,000 t/day in 2025 — equal to household demand for about 550,000 people — with reuse volumes up 54% over four years to 73.59 million tons. Icheon produces 94,400 t/day of recycled water on site; Cheongju became the first Korean semiconductor plant to take reclaimed sewage in 2023. Cumulative savings hit 303.37 million tons by end-2025, against a new 600-million-ton target by 2030. For buyers, the signal is that advanced wastewater treatment (ozone, activated carbon, multi-stage coagulation) plus on-site reuse is the procurement benchmark at six-figure-m³/day scale.
SK hynix cuts Korean chip-plant water use by 170,000 t/day, Sept 2026
On 15 September 2026, at Korea International Water Week 2026 in Daegu, SK hynix reported cutting daily water use across its Korean chip plants by an average of 170,000 tonnes in 2025, equivalent to the daily household use of 550,000 people. Cumulative savings of 303.37 million tonnes have beaten a 264 million-tonne target, with a 2030 goal of 600 million tonnes. The Icheon plant runs a wastewater recycling facility delivering 94,400 m³/day of reused water to scrubbers, using ozone, activated carbon and multistage coagulation and sedimentation. For operators, the disclosure pins a real-world tertiary-and-reuse reference at fab scale worth benchmarking.
South Bend mayor bans data-center NDAs after Amazon wastewater disclosure, Sept 2026
On 17 September 2026, South Bend, Indiana Mayor James Mueller signed an executive order barring city staff from signing non-disclosure agreements about data-center projects, after an Amazon-related NDA covering wastewater discharges surfaced. Amazon used about 30 million gallons of the South Bend Wastewater Treatment Plant's capacity between August 2024 and July 2025, ranking it 11th among the plant's users, well behind Cleveland-Cliffs, Notre Dame and the South Bend Ethanol plant. A separate council ordinance that would add a $2,500 penalty and review past secrecy deals is headed for a first reading on 28 September, with the mayor signalling a veto. For plant managers, the case is a procurement-side signal on how municipal utilities will handle trade-waste contracts with hyperscale data-center tenants.
SK hynix cuts 170,000 tons of water a day at Korean fabs, September 2026
At Korea International Water Week 2026 in Daegu on 8 September, SK hynix disclosed that it cut water consumption at its domestic fabs by an average of 170,000 tons per day in 2025, equivalent to household use by more than 550,000 people for a day. The company, which has run a Water and Wastewater Reduction Task Force since 2018, has reached 303.37 million tons of cumulative savings and is targeting 600 million tons by 2030, with reuse volumes up 54% since 2022. For plant managers and procurement leads, the read-across is that tertiary polishing trains using ozone, activated carbon and multistage coagulation are the configurations that let fab sites push reuse into the 50%-plus range.
