From the work blog, water conservation in a wet place:

The rooftop rainwater catchment system and other features built into Kay Helt’s home and surrounding neighborhood in Stenløse, in the Danish farm country outside Copenhagen, captures some 70 percent of the annual rain that falls from the sky. It seems like a wet place – it gets two to three times the annual rainfall here that we receive in Albuquerque. But according to Sune Rotke, who showed a group of visiting U.S. and European journalists around this week, the region is overpumping groundwater for municipal consumption (sound familiar?) and has an estimated 15 to 25 years before shortages are anticipated.
