Cooling, Water and Data-Centre Construction Supply Chain — 2026-09-09
The data centre supply chain faces a trifecta of constraints this week: acute labour shortages delaying AI hall construction, intensifying political scrutiny over water usage, and record backlogs for cooling equipment. While Vertiv and other suppliers report massive order books, the physical bottleneck has shifted from chip supply to skilled electricians and water permits.
Cooling, Water and Data-Centre Construction Supply Chain — 2026-09-09
Top developments
Construction Labour Shortage Becomes Primary Bottleneck
The AI data centre boom is hitting a hard ceiling due to a lack of skilled tradespeople. IBTimes reports that the construction sector needs 349,000 new workers in 2026 alone, with Deloitte estimating a $124 billion loss in output if the gap isn't closed, noting a shortfall of over two million skilled trade workers by 2028. This shortage directly impacts the deployment of liquid cooling systems and high-density power infrastructure required for Nvidia’s latest racks. Operators are increasingly forced to poach talent from telecommunications and utility sectors, as noted by Construction Dive, to keep projects on schedule.
Water Usage Sparks Political and Community Backlash
Water usage has moved from a technical metric to a major political issue. TechRadar highlights a report stating that data centres in just seven U.S. states are using more water than all the cities in California combined, totaling 10.4 million acre-feet. This statistic is fueling local opposition, exemplified by a viral incident in Denver where a new data centre was caught watering its lawn while neighbours faced drought restrictions. These disputes threaten to delay approvals for new AI halls, particularly in the Sun Belt, forcing operators to accelerate the adoption of closed-loop liquid cooling to reduce evaporative demand.
Cooling Equipment Backlogs Remain Critical
Despite labour issues, demand for cooling hardware remains insatiable. Cyprus Mail reports that power and cooling firms are riding a "trillion-dollar" boom as developers race to avoid infrastructure bottlenecks, with Vertiv and others seeing sustained order growth. Vertiv recently highlighted how liquid cooling platforms are evolving from design to deployment as rack densities exceed 100 kW, requiring new testing standards that many contractors are still adapting to. The market for AI data centre liquid cooling is projected to reach $23.23 billion by 2035, up from $3.39 billion in 2025, indicating a long-term structural shift away from air cooling.
Union Electricians vs. Community Opposition
A social fracture is emerging between labour unions and community activists. NPR reports that union electricians are welcoming the data centre boom due to high overtime pay, putting them at odds with local communities trying to block construction over environmental concerns. This dynamic complicates permitting processes, as local governments face pressure from both pro-jobs unions and anti-water-use constituents. The IECI notes that data centres have become a divisive national issue that could shape the 2026 elections, adding regulatory uncertainty to the supply chain.
Local view
In China, state media and financial outlets like CCTV Finance and Sina report that orders for liquid cooling servers are booked out until the end of the year. The Chinese liquid cooling market reached 15.98 billion yuan in 2025 and is expected to surpass 100 billion yuan globally for smart computing in 2026. Suppliers like Envicool and Shenling Environment are accelerating production to meet demand from domestic hyperscalers like ByteDance and Alibaba, who are deploying ultra-dense AI clusters. The narrative emphasizes that traditional air cooling can no longer handle the thermal load of next-generation AI chips, making liquid cooling a mandatory standard rather than an option.
Context & numbers
- Labour Gap: The U.S. construction industry needs 349,000 new workers in 2026; the total skilled trade shortfall is projected at >2 million by 2028.
- Water Consumption: Data centres in seven U.S. states consume 10.4 million acre-feet of water annually.
- Market Size: The global AI data centre liquid cooling market is forecast to grow from $3.39 billion (2025) to $23.23 billion (2035) at a CAGR of 21.21%.
- Chinese Market: China's liquid cooling data centre market was valued at 15.98 billion yuan in 2025.
On the radar
- UK Job Claims: A new think tank analysis challenges tech sector projections on permanent job creation from UK data centre buildouts, potentially influencing government support policies.
- Trucking Supply Chain: CNBC notes that truckers are benefiting from the boom as components like HVAC, tubing, and wiring arrive by road, mitigating some port delays but highlighting reliance on domestic logistics.
- Wastewater Pollution: The Guardian reports growing alarm over wastewater pollution violations by US data centres, including "forever chemicals" and rare bacteria, which could trigger stricter discharge permits.
