Project Blue, a large data center proposed for near the Pima County fairgrounds, promised to build a pipeline for reclaimed water big enough to serve other users besides itself. But a draft of the contract with the city raised questions about whether the city would pay a share of pipeline costs after all. … The City of Tucson is still bound by a non-disclosure agreement that forbids revealing who will actually operate the data center. One thing not under wraps was a promise from Beale Infrastructure, the company building the project. That was to build a pipeline 18 miles long to bring reclaimed water to cool the center, and to oversize it so the city could have extra capacity for other projects. … So is Project Blue paying to build the City of Tucson an oversized water line or not?
