This is the intake structure for the city of Albuquerque’s San Juan-Chama project water. It’s just south of Alameda on the east side of the Rio Grande. (here on Google maps, but it hadn’t been built yet when this satellite image was taken.)
The water comes across the continental divide out of the San Juan River watershed, and is dumped into the Chama River – hence the name. We’re going to start using this water for our city drinking water beginning in 2008 under the current schedule. Currently, we pump fossil groundwater, but that is unsustainable.
