Preparedness Information

Plan a residential rainwater collection system around your intended use, roof yield, storage capacity, overflow, and maintenance. A storage tank is only one part of the system.

Commercially bottled water has date and storage guidance, while self-filled emergency water should be rotated. Learn how containers, heat, contamination, and inspection affect safety.

Emergency water shelf life depends on its source, container, seal, storage conditions, handling, inspection, and the manufacturer's or public-health rotation guidance.

Store emergency drinking water safely with purpose-built containers, a potable source, protected placement, inspection, rotation, and backup treatment.
