Apple’s construction plans in central Oregon include 500,000 sq ft of data center space, according to an Associated Press report.

The company has been building a 10,000 sq ft data center at its Prineville, Oregon, site, but has recently filed plans with local officials for the much-larger construction project it was expected to undertake in the rural town that is also home to a large Facebook data center site.

As part of the plan, Apple will help the city increase the capacity of its water system. City employees recently found an underground water stream – a new source of water for the town that has been suffering from low flows in its wells, according to AP.

City Manager Steve Forrester said the stream, with Apple’s help, would be converted to production wells, but the company would be eventually reimbursed for its investment in the water-infrastructure project.

“It will give them the water they need, and it gives us ... more capacity than they are consuming,” Forrester was quoted as saying.

Apple did not disclose timeline of the massive data center construction project.

The news comes two days after Facebook filed plans to add a 62,000 sq ft data center to the capacity it already has and is currently building in Prineville. It has a 300,000 sq ft data center there and is currently building out an identical one.

Also earlier this week, Cupertino Electric, an electrical engineering and construction company that does a lot of data center projects, announced it had opened an office in Prineville. The company said it chose Prineville so that it could serve its existing central-Oregon customers and future ones, as the region was poised to grow as a data center hot spot.
