Things You'll Need
Instructions
Find a 5-gallon bucket with a self-sealing lid. Many products are sold in this type of bucket such as paint, chemicals used by farmers and cleaning fluids. This type of bucket is sturdy and comes with a self-sealing lid. The height also makes it comfortable for use as a portable septic tank.
Purchase a bag of potting soil or fill a small garbage bag with soil from your garden. Recycle a food can or plastic container to use as a scoop in your bag of soil.
Use the 5-gallon bucket for waste deposits excluding urine. Pour a scoop of soil over your deposit each time you use your portable septic tank. Replace the lid on the bucket, but leave the pour-spout cover open and set the bucket outside your tent when not in use. Leaving the pour-spout open will prevent moisture from collecting on the inside of the lid.
Save juice containers with screw-on lids. Use these for urine to prevent filling your solid waste septic tank too quickly. Close tightly to avoid leaks. Upon returning to civilization, empty these containers into a regular flush toilet.
Upon leaving camp, cap the pour-spout of your portable septic tank bucket. At home, set your bucket in a discreet area and fill the bucket with alternating layers of soil, leaves, grass clippings or other vegetative matter. Replace the lid. Leave the pour-spout closed. Microbes in the soil will begin the decomposition process. In a matter of months, the entire bucket of waste will be compost. Heat build-up during the decomposition process will kill harmful bacteria. Mulch your shrubbery with the compost.
