Puerto Rico has announced it will implement water rationing measures in San Juan and other major cities as a drought grips the United States territory with no relief in sight. More than 180,000 Puerto Ricans will be without water for 48 hours at a time on a rotating basis starting Friday. She said she did not know how long the rationing measures will remain in place. Almost 25 percent of Puerto Rico is experiencing a severe drought and another 36 percent is under a moderate drought, according to the US Drought Monitor. Puerto Rico previously implemented rationing measures in 2020 and in 2015, when some 400,000 utility customers received water only every third day.
