Connect the public water utility to a bitcoin mining operation, with contractual rights to dial down/turn off the bitcoin mining and use that electricity as backup should the water treatment plant's other source of electricity fails. When they don't need the backup power it provides security to the bitcoin network, and when they do need it, its there.
