If California's much anticipated "big one" were to hit today, would you be ready?

When we've talked about this before, one of the things our experts emphasized was the importance of storing water. Southern California takes the majority of its water from faraway resources, so in the event of a major disaster, the area would likely be cut off from its water source.

Because April is earthquake preparedness month, we thought we'd turn to an expert on what to do in an emergency -- someone's who's all about preparing for the worst-case scenario.

Christopher Nyerges has been teaching survival preparedness in L.A. for over 40 years. Whether it's the big one, or if you just want to get ready in case there's another drought, Nyerges has a few tips on how to improve and store up your own water supply.

Storing water 101

Pro-tip: Christopher recommends using the plastic containers that house carbonated water. "I specifically save those because those will last up to five or six years before springing a leak," he says.

Debunking an old myth: "People used to suggest adding chlorine to your water if you're going to store water if you're worried about an earthquake," said Nyerges, "You already have it in your tap water." The only reason you'd add chlorine because it might develop algae in a few years time. It's not toxic, it's just a natural occurrence.

Take control as an individual

Litmus test—Nyerges also recommends testing the acidity of rain collected, especially if you plan to use it for drinking. However, if it's strictly for the yard it doesn't matter.

Pro-tip: When it comes to collecting rainwater, Nyergest has often encouraged people to paint their roofs white. "There's a liquid rubber product that building supply places sell. It's for RV's, typically to make it cooler..."

When using this product, the rainwater slides off the rubber roof and doesn't collect the grime and dirt one may get on regular types of roofs.
