Quick Answer
Local emergency water supplies can be stored in containers, cisterns, or tanks. Consider installing a rainwater harvesting system or connecting to a municipal water supply. You can also check with your local government for any regulations or guidelines.
Evaluating Storage Needs
When determining the amount of water needed for emergency storage, a general rule of thumb is to store at least 1 gallon per person per day for drinking, cooking, and hygiene. This translates to 30 gallons per person per month. For a family of four, this would be 120 gallons per month, or about 1,440 gallons per year.
Choosing a Storage Container
When selecting a storage container, consider factors such as material, size, and durability. Food-grade plastic or stainless steel containers are good options. A 55-gallon drum is a common size for water storage, but larger containers may be more suitable for families or households with multiple users. Be sure to use a container with a tight-fitting lid to prevent contamination and evaporation.
Implementing a Rainwater Harvesting System
A rainwater harvesting system can be a valuable source of emergency water. These systems typically consist of a roof catchment area, a first flush device, and a storage tank. A typical roof catchment area can collect up to 600 square feet of surface area, which can yield around 300-400 gallons of water per inch of rainfall. Consider installing a system with a 1,000-gallon storage tank to provide a reliable source of water during emergencies.
