Spotsylvania holds three water-reuse service agreements for data-center cooling: Cosner Tech Campus up to **1,260 gpm ≈ 1.8 MGD**; the Mattameade Amazon complex max **1,980 gpm ≈ 2.8 MGD** once the reuse system is built; Powerhouse 95 max **700,000 gal/d**. An Amazon annotation says maximum draw would be needed only ~4.1% of the year, but the agreements contain no clause limiting use to that share or requiring air-cooling priority; ~60% of cooling water is lost to evaporation.
