Elon Musk's artificial intelligence company, xAI, has put plans for a major wastewater treatment facility in Memphis on hold as it focuses on completing construction of its second Colossus data center in the city. The $80 million Colossus Water Recycling Plant had been touted as a way to reduce strain on the Memphis Aquifer, but Musk said xAI will prioritize the Colossus 2 project first.

Why it matters

The Colossus Water Recycling Plant was seen as an important sustainability initiative that would have helped conserve the Memphis Aquifer, a critical water source for the region. Its delay raises questions about xAI's commitment to environmental initiatives as it rapidly expands its data center footprint in the area.

The details

In January 2026, the Tennessee Department of Environment and Conservation approved an operations permit for xAI affiliate CTC Property LLC to build the recycled wastewater treatment facility. Since then, seven construction permits totaling over $17 million have been filed for the project. However, in an April 9 social media post, Musk said xAI is now focusing on finishing the Colossus 2 data center before prioritizing the water plant.

  • In January 2026, the Tennessee Department of Environment and Conservation approved an operations permit for the Colossus Water Recycling Plant.
  • Since January 2026, seven construction permits totaling over $17 million have been filed for the water recycling facility.
  • In October 2025, elected officials and xAI staff celebrated a ceremonial groundbreaking for the wastewater treatment plant.
  • In March 2025, the Memphis City Council approved the land acquisition for the water plant site.
  • In February 2025, xAI affiliate CTC Property LLC purchased 186.13 acres for $79.9 million, which was later transferred to another xAI affiliate, MZX Tech LLC.

What they’re saying

“xAI is focusing on completing construction at Colossus 2 before prioritizing the water recycling plant.”

— Elon Musk, CEO, xAI

“xAI remains committed to building a state-of-the-art water recycling plant in Memphis.”

— xAI

What’s next

The City of Memphis has a small buyback clause in the land purchase agreement if "substantial construction" on the water recycling plant has not been completed within one year. The city would then have the right of first refusal if xAI were to sell the 13-acre site.

The takeaway

xAI's decision to pause the Colossus Water Recycling Plant in Memphis raises concerns about the company's commitment to sustainability initiatives as it rapidly expands its data center footprint in the region. The delay could impact the city's efforts to conserve the critical Memphis Aquifer water source.
