BOGOTA, Colombia (AP) — Luis Soler is caring for water as if it were the most expensive ingredient at his restaurant in Colombia’s capital.

For the first time in 40 years, a severe drought pushed the city to start rationing tap water. At Soler’s restaurant in Bogota, nothing flowed through the pipes Friday. The city’s warnings allowed him to prepare for the change, buying bottled water for cooking purposes and storing tap water for dish washing, and since his entire neighborhood was facing the same inconvenience as the restaurant, he said he expected sales to go up, not down.

“I think the impact is not going to be much. On the contrary, we are waiting for sales to improve a little because there is no water in the neighborhood and many people are not going to cook,” Soler said.

Officials in Bogota moved to ratio water after reservoirs hit historically low levels due to the combination of high temperatures and lack of rainfall prompted by the El Niño climate phenomenon.
