Materials and Tools

To build a compost toilet, you will need the following materials and tools:

  • A 55-gallon drum or other large container
  • A saw
  • A drill
  • A jigsaw or band saw
  • A hammer
  • Nails or screws
  • A shovel
  • A tarp
  • A bucket
  • A hose

  • A ventilation pipe
  • A fan
  • A timer

Building the Compost Toilet

Once you have gathered your materials and tools, you can begin building your compost toilet. The following steps will walk you through the process:

1. Dig a hole. The hole should be large enough to accommodate the 55-gallon drum and should be dug at least 3 feet deep.
2. Place the drum in the hole. The drum should be placed so that the open end is facing up.
3. Cut a hole in the drum. The hole should be large enough to accommodate the toilet seat.
4. Install the toilet seat. The toilet seat can be made from a piece of plywood or another material. It should be attached to the drum with nails or screws.
5. Line the drum with a tarp. The tarp will help to keep the compost from leaking out of the drum.
6. Add compost. The compost can be made from a variety of materials, such as leaves, grass clippings, and food scraps.
7. Cover the compost with a bucket. The bucket will help to keep the compost from drying out.
8. Install the ventilation pipe. The ventilation pipe will help to draw air into the compost pile and promote decomposition.
9. Install the fan. The fan will help to circulate the air in the compost pile and speed up decomposition.
10. Set a timer. The timer will help you to keep track of how long the compost has been fermenting.

Once your compost toilet is built, you can begin using it. Here are a few tips for using a compost toilet:

  • Only flush biodegradable materials. This includes things like toilet paper, paper towels, and food scraps. Do not flush anything that is not biodegradable, such as diapers, sanitary products, or pet waste.
  • Cover your waste with a layer of compost. This will help to keep the flies away and prevent the compost from smelling.
  • Turn the compost pile regularly. This will help to speed up the decomposition process.
  • Empty the compost pile when it is full. The compost pile should be emptied when it is about two-thirds full. The compost can then be used to fertilize your garden.

By following these tips, you can easily build and use a compost toilet in your own backyard. Compost toilets are a great way to reduce your environmental impact and save money on your water bill.

Maintaining the Compost Toilet

Once your compost toilet is up and running, there are a few things you can do to maintain it and keep it working properly.

Emptying the Compost Chamber

The compost chamber in your toilet will need to be emptied regularly, depending on how much you use it. A good rule of thumb is to empty it every few weeks or so. To empty the compost chamber, simply remove the lid and scoop out the compost into a compost pile or other designated area. Be sure to wear gloves to protect your hands.

Aerating the Compost

It is important to aerate the compost in your toilet regularly to help it break down and decompose properly. You can do this by stirring the compost with a pitchfork or shovel, or by using a compost aerator. Aerating the compost will help to improve the airflow and drainage, which will speed up the decomposition process.

Adding Water to the Compost

The compost in your toilet will need to be kept moist in order to decompose properly. If the compost becomes too dry, it will not break down as quickly and may start to smell bad. To keep the compost moist, simply add a little water to it every few days.

Monitoring the Compost

As the compost in your toilet decomposes, it will start to produce heat. This is a natural process and is a sign that the compost is breaking down properly. However, if the compost starts to produce too much heat, it could be a sign that there is too much moisture in the compost. To correct this, simply add a little more dry material to the compost.

Troubleshooting

If your compost toilet is not working properly, there are a few things you can check to troubleshoot the problem.

  • Is the compost chamber full? If the compost chamber is full, the toilet will not be able to function properly. Empty the compost chamber and try again.
  • Is the compost too dry or too wet? If the compost is too dry, it will not decompose properly. Add a little water to the compost and try again. If the compost is too wet, it could be a sign that there is too much moisture in the compost. To correct this, simply add a little more dry material to the compost.
  • Is the compost producing too much heat? If the compost is producing too much heat, it could be a sign that there is too much moisture in the compost. To correct this, simply add a little more dry material to the compost.

If you have tried all of these troubleshooting steps and your compost toilet is still not working properly, you may need to contact a professional for assistance.
