Barcelona may need water shipped in during a record drought in northeast Spain, authorities say

Tighter water restrictions for drought-stricken northeast Spain went into effect Wednesday, when authorities in Catalonia said that Barcelona may need to have fresh water shipped in by boat in the coming months.

Catalonia is suffering its worst drought on record, with reservoirs that provide water for about 6 million people, including Spain’s second-biggest city Barcelona, filled to just 18% of their capacity. By comparison, Spain’s reservoirs as a whole are at 43% of their capacity.

Spanish authorities and experts point to the impact of climate change in the increasingly hot and dry weather behind the extended drought in Catalonia.

Barcelona has already been relying on Europe’s largest desalination plant for drinking water, and a sewage treatment and purification plant to make up for the drop in water from wells and rivers.

Catalonia officially entered the “pre-emergency” phase for drought, which lowers the daily use per person from 60 to 55 gallons of water per day. That includes personal use as well as what town halls use per inhabitant for services. Catalonia’s water agency says that the average person in Catalonia consumes on average 30 gallons per day for domestic use.

Pray for rain: Spanish farmers hold unique Mass amid drought

In drought-stricken Spain, around 250 villagers brought back the faded practice of a special Mass and procession to pray for rain.

Municipal governments are now prohibited from using drinking water for street cleaning or to water lawns. Water limits for use in industry and agriculture have been increased.

If water reserves fall below 16% capacity, then Catalonia would enter into a full-blown drought “emergency” whereby water would be limited to 52 gallons per person, and then potentially dropped down to 42 gallons per person, and all irrigation in agriculture would require previous approval.

Authorities have warned that the drought “emergency” could just be weeks away, unless it rains — a lot.

If not, then Barcelona could need tankers to bring in drinking water. In 2008, that extremely expensive measure was used to keep the city supplied during a drought.

“Unfortunately, we have to be prepared for every scenario, and we are close to needing boats to bring in water if the situation that we have seen over the past months continues,” Catalonia regional president Pere Aragonès said during a trip to South Korea on Wednesday.

Aragonès said that his administration was working with Spain’s ministry for the ecological transition to prepare for the eventuality of the water tankers. He added that his administration would prefer to bring in water for southern Catalonia where the Ebro River meets the Mediterranean Sea.
