During the survival days of the EMP strike, you should learn to deal with the human waste. If you have a septic system, you may learn to flush without running water:
In the case of emergency, a cat hole will help you and you can use a garden shower to dig a 6 to 8 inches deep hole. You can do your waste in the hole and wipe with the help of toilet paper. Cover the hole with the dirt that you dig out. The cat hole should be away from any water source; therefore, there is no need to dig a hole in the area of rain water or flowing water.
A dugout toilet is a great alternative of the modern commode. You can use it during your longer off-grid stay. It is easy to build and perfect for the use of six months. It is similar to cat hole, but it is a large hole. Excavate this hole approximately 200 feet away from the water supply and the dimensions will be 1.5 feet wide x 1 foot deep x 2 feet long. You can build a privacy partition to deal with the emergency situation. You can use some stakes and blankets to cover the toilet area for privacy. After doing your business, cover it with wood ash or quick lime to avoid flies and pests.
