How to build a diy composting toilet

The toilet is one of the most important household blocks in the country. And although the design of most street closets does not raise any questions, it still makes sense to touch upon the construction of this strategic facility.

The standard construction based on a cesspool is not convenient for everyone. For those who do not want to suffer with the arrangement of a backlash closet, there is a good alternative, namely a country peat toilet. It is useful not only when there is no sewage system in the house, but also as an alternative to a regular restroom in the summer.

Peat composting toilet for a summer residence

The principle of operation of a composting toilet for a summer residence is quite simple. A container (usually a bucket) is installed under the toilet or platform on which the toilet seat is held to collect sewage. Dry peat is poured into it, which converts waste into compost. In turn, the liquid that accumulates in the container partially exits through the drain hole, and partially evaporates through the ventilation hatch. The resulting mixture can be used as soil fertilizer.

The very idea of ​​powder closets is not new, but until recently, instead of peat, dry sawdust was used, which processes waste much more slowly.

According to reviews about peat toilets, this installation has a number of advantages: There is no need to dig a deep cesspool, and after filling it, move the toilet to another place. This greatly facilitates the everyday life of summer residents, especially if groundwater flows underground. Environmental friendliness of the design.

A peat composting toilet is one of the varieties of dry closets. It does not harm the environment, does not lead to poisoning of closely flowing groundwater, but, on the contrary, contributes to the fertilization of the soil. Installation of a compost closet does not take much time and does not require any complex technical knowledge. In addition, peat for peat toilets is quite inexpensive.

Of course, this type of construction also has disadvantages that we cannot fail to mention. Fortunately, there are not many of them: The need for regular emptying of the filled container and the purchase of peat, which is time-consuming and costly. Besides, this is a rather dirty and unpleasant concern.

Possibility for use only in conditions of freezing temperatures. The temperature at which peat converts waste into compost must be at least +10 degrees. In this regard, it is possible to use a peat toilet for a summer residence only in the spring-autumn period.


Composting toilet system and design

Peat or as they are also called composting (from the word “compost”, powder – closet) dry closets are of several types. They are distinguished by the design of the bunker (carousel or drum), the number of chambers and the method of removing liquids. It is worth noting that any of the listed toilets have two main parts: a ventilation system (pipe) and a reactor. The advantage of such a toilet is that crushed peat very quickly and well processes organic matter (waste) into compost mass. Rather, this all happens thanks to special bacteria that are contained in peat.

In order to make a simple version of a peat dry closet, it is enough to equip a seat (toilet seat). You will also need to pick up a container into which peat will be poured. You will also need to make a compost pit. You will have to buy peat.

What is the work of a peat composting toilet

A person sits on a toilet seat, his waste falls into a special container with peat located below. As a container, you can use an evaporation tank, a metal bucket or other container suitable for this business.  After the person has done his job, a portion of the peat mixture is poured over the waste. Gardeners, for example, add sawdust to peat. This is done in one-to-one proportions.

That is, in the end result, it turns out that the container is filled in layers: went to the toilet once – fill up one layer of peat, went to the toilet again – add another layer of peat. The most important plus of this action: all sorts of odors are destroyed, waste is processed quickly and efficiently. As soon as the filling (to the very top) of the container of your choice occurs, take it and pour all the contents into a special compost pit. Don’t forget to add a layer of peat mixture on top.

Remember: always keep a container containing dry peat next to the toilet seat. The peat must be dry.  If you do not want to keep it next to the toilet seat, you can make it in the form of a toilet cistern, the option is convenient and will save space. You can screw the wheels to the container, which is under the toilet seat, and equip it with a slide (it all depends on the capacity). That is, each summer resident decides for himself how best to do it for his own convenience.

You also need to prepare a trench, thanks to which fluids will be drained. Do not forget to prepare a special pipe.

Thus, although you will spend money on peat, in the future there will be no need to buy fertilizers for your favorite garden or vegetable garden. That is, in any case, you will always be in the


How to make a compost toilet not smell

5 proven ways to get rid of the smell in a country toilet

An unpleasant smell in a country toilet is a topic that excites many, but not everyone knows that getting rid of the stench is not at all difficult. Let’s consider several popular and affordable methods.

To solve the problem, and not disguise it, you first need to understand the reasons. In fact, there is only one reason for the unpleasant smell – improper ventilation in the toilet, but how to fix the situation? Let’s figure it out.


Ventilation in the composting toilet

The ideal option is when the ventilation system was thought out even during the construction of the toilet, which means that there is an extractor hood in the toilet house. If not, then a plastic or metal pipe can be inserted into the cesspool box and led out through the roof of the toilet so that its upper edge is located at a height of 2.5-3 m from the ground.

Seal the insertion point, paint the part of the pipe above the roof with black paint. The solar heat will heat the pipe and work according to the hood principle.

The depth of the cesspool must be at least 2 m, and the material from which it is made must be waterproof.

You can also arrange natural ventilation in the toilet: make a window in the wall or make a hole closer to the floor. Seal the hole or window with a mosquito net so that insects do not enter the house.

Chemicals for the composting toilet

The main advantages of using chemicals are speed and independence from weather conditions (“chemistry” can be used both in winter and in summer). There are several types of these drugs:

Nitrate products are the most environmentally friendly, but they are quite expensive. Due to the content of surfactants (surfactants), nitrate oxidants not only help to cope with odor, but also have detergent properties (Deo Tural, Devon-N);

Ammonium preparations are also among the safest and most effective means, but when using them, they should not be allowed to come into contact with soap solutions, for example, after washing (Bio-san);

Bleach is an extremely toxic and carcinogenic substance, but at the same time one of the most accessible and cheapest.

When working with chemicals, be sure to use protective equipment (respirator, gloves, etc.), observe safety rules and strictly follow the instructions on the package.

After using chemicals, the contents of the cesspool (or septic tank) must be disposed of and in no case used as fertilizer. By using all this your diy composting toilet won’t smell.

Folk remedies for the smell in the composting toilet

There are several natural remedies that can help you get rid of the smell in your composting toilet:

  • sawdust or ash (pour 1 cup after each use of the toilet);
  • cut grass (also added after each visit);
  • tops of tomatoes or nettles (repel insects and absorb ammonia, you need to add it weekly).

These methods are harmless to the environment and do not require special financial costs. Folk remedies quickly neutralize the smell and decompose the contents of a septic tank or cesspool, while the resulting compost can be further used in the beds.

Bio Activators for composting toilet

Bio Activators are modern preparations that are a concentrate with strains of bio bacteria. In order for these bacteria to live, they need a sufficient amount of organic matter, moisture and an air temperature above 0 ° C.

Such biological agents help in waste disposal, neutralizing sewage in the cesspool, destroying harmful microorganisms and eliminating unpleasant irritating odors. When using bio activators, the filling of the cesspool decreases over time.

The bioactivator can be purchased as a liquid, powder, or tablets. In an ordinary country toilet, only 1 tablet may be enough, which will cope with 1 cubic meter of sewage. It is necessary to use funds according to the instructions on the package.

Rules for the use of bio activators

  • if you decide to use bio activators, try to exclude chemicals from entering the cesspool, otherwise living microorganisms may simply die;
  • be sure to monitor the ventilation of the toilet;
  • it is pointless to use bio activators in early spring or late autumn, since microorganisms die at low temperatures;
  • correctly correlate the amount of waste and the required amount of microorganisms. If there are too few of them, they will not cope with the task and simply will not survive.

The result of the bio activators’ work becomes noticeable about a week after their use.

Peat fillers – what they are and how they work

Recently, many summer residents have installed dry closets on the plots, and in order for the sewage to be processed into compost, they use a peat mixture. It loosens the mass, eliminates odor, absorbs fumes and recycles waste.

Advantages of peat fillers:

  • quickly compost waste;
  • prevent the compaction of the masses;
  • absorb moisture;
  • prevent the appearance of insects;
  • safe for nature.

When choosing a peat filler, it should be borne in mind that mixtures containing active calcified high-moor peat absorb odors more efficiently and start the waste processing process faster.

The most effective method for eliminating “odors” in a street toilet is to combine one of the proposed methods with improving the ventilation system.
