11 best dry closets

A vital place in the house or in the country is a toilet. In remote regions, where there is no centralized sewage system, and there are problems with waste disposal, a bio-toilet comes to the rescue. Such a modern plumbing device has several advantages over the traditional cesspool. The main one is the ease of operation and reasonable price. Today, the range of biological toilets in the domestic market is quite wide. With the help of experts, gardeners will be able to find the most efficient and comfortable model.

How to choose a dry closet

1. Types of dry closets. According to the method of disposal of human waste, there are three varieties. These are electrical, chemical, and dry (composting) models. Each species has its strengths and weaknesses.
2. Storage tank capacity. Since the human bioorganic is not removed anywhere from the toilet, as is the case with the usual toilet, the volume of the storage tank becomes an important characteristic of the dry closet. The first thing to consider is the number of residents who will use the device. If for lonely summer residents a reservoir with a capacity of 40-50 liters is enough for a season, then a full-fledged family of 4 people can serve a 100-200 liter drive.
3. Tank weight. When it comes time to clean the toilet, the user will face such a problem as a large tank weight. Some manufacturers equip capacious containers with wheels, smaller tanks have handles. For older people, it is preferable to choose the lightest models (up to 15 kg).
4. Filling indicator. For timely cleaning of the storage container in many biotoilets there are filling indicators. This useful feature helps to avoid unpleasant "overload" with all the ensuing consequences.
5. Stool height. The actual characteristic for children and the elderly is the height of the seat of the composting toilet. The standard value is considered to be the limit from 40 to 45 cm.
6. Drain method. After each trip to the bio-toilet, it is necessary to carry out a conditional discharge. In some models, a piston pump is used, in other devices, an electompomp is installed for this, and in dry products powder is produced by peat chips.
7. Ventilation. A necessary option of each dry closet is effective ventilation. It allows you to remove unpleasant odors out. It is important not only to select a system with a certain height and throughput, but also not to forget about such elements of protection against flies as the grid.
