When disaster strikes it often affects one or more of the utility systems in our homes. Therefore, it is important to know where the main controls are located and to know when and how to turn them off. It is best to learn these things before disaster strikes.
Here are a few helpful pointers:
Your sewer system could be damaged in a disaster such as an earthquake, landslide or flood.
If you have one of the more modern septic systems that use an electrical pump to force gray-water into the drain field, you may encounter septic system problems during a power outage. If the electrical power is off for an extended time, and you continue to use water as you normally would, the septic tank will quickly fill up and sewage may back-up into your home.
