With Spain's average rainfall down 40 percent last year, many cities have restricted residents from filling their swimming pools or watering their lawns. But perhaps no municipality has developed such diverse and creative solutions as hard-hit Barcelona, which this week began a €44 million ($68 million) operation to bring in drinking water by ship.
On Tuesday, the first vessel - from the southern city of Tarragona - arrived in Barcelona's port, where firemen discharged the ship's 20 tanks into a pipeline linked to the city's water distribution network. The next day, Barcelona residents were drinking Tarragona water from their taps.
The measure is designed to stave off a water crisis that has been building for some time and has reduced Barcelona's reservoirs to 20 percent of their capacity.
"For the past four years, we've had a shortage of rain," says Narcis Prat, a water expert at the University of Barcelona. "Now we have a shortage of water. Without significant rain, we only have enough to last until December."
Professor Prat points out that the population of Spain's second-largest city has grown by more than 1.5 million in the past 15 years, stretching limited resources further. That means the citizens' "excellent" conservation habits aren't enough, says Barcelona's mayor, Jordi Hereu.
"The area of Barcelona is exemplary in its consumption," he says. "But we're talking about 5.5 million people.... And all of them have a right to water."

The debate over the pipeline, which should be completed in October, has become so fierce that it's been dubbed the "water wars."
But even cooler heads see problems with it. "What we need is something that isn't just one-way. What we need is a whole network that guarantees supply ... so that water can circulate throughout the region," says Professor Armengol.
Local officials and the regional water authority argue that the multiple efforts will guarantee supplies in both the short and long term.
