How's your emergency drinking water situation? Are you prepared?
Literal
Emergency-time [gen-の] drinking-water [gen-の] securing [topic-は], all-right is-[question-ですか]?
A disaster-preparedness awareness question. 緊急時 ('emergency time') is a Sino-Japanese compound. 飲料水 ('drinking water') is a formal compound (as opposed to casual 飲み水). 確保 ('securing, ensuring') is a formal noun-verb meaning 'to secure a supply.' 大丈夫ですか? is the polite 'is it OK? / are you fine?' — here used in its 'is everything squared away?' sense, common in safety or preparedness contexts.
