Under the new 48-hour water rationing schedule, residents across affected areas, including parts of San Juan, lose access to running tap water for two full days at a time. To cope with the shortages, families are relying heavily on municipal water tankers and home storage tanks to collect enough water for drinking, cooking, and cleaning.
