The only option that allows you to ensure comfortable living in a country house is a cesspool for a toilet, into which it will be possible to divert the waste products of people living permanently or temporarily in a country house or cottage.

If there is water supply in the country house, the cesspool for the toilet is one of the necessary treatment facilities that can ensure the maintenance of order, cleanliness and the ecological state of the adjacent territory.

Toilet pit options

In practice, in the absence of a central sewage system, the following options are used to equip treatment facilities in a suburban area:

• storage system of drains;
• local sewerage with biotreatment.

In addition, such sewer structures are: non-volatile (the flow of liquids occurs naturally) and volatile (sewage is pumped using special pumps). Most often, storage systems are a sealed tank or a cesspool for a toilet with an earthen bottom. See also: "".

Do-it-yourself cesspool with an earthen bottom

The simplest arrangement of a cesspool is a pit with an earthen bottom, which acts as a natural filter. This option is currently most in demand if the owner of the dacha intends to build a toilet with a cesspool with his own hands, subject to low water consumption, since then it will not be necessary to use the services of sewers often.

The main disadvantage of cesspools without sealing is that the absorption of liquid by the soil occurs rather slowly, and when a large family lives permanently in the country, it cannot cope with significant volumes of sewage and sewage.

According to the requirements of SNiP, such a do-it-yourself toilet pit is capable of processing a maximum of one cubic meter in a natural way during the day.

It should be noted that earth pits are potential environmental pollutants, especially when fecal effluents are mainly dumped into them. Wastewater in cesspools is recycled by bacteria living in the soil. But in those cases when the volume of sewage exceeds the volume with which the natural biofilter is able to cope, the effluents in an unchanged, and therefore unprocessed form, penetrate into the deep layers of the soil.

As a result, contaminated liquid mixes with underground water layers and renders well water unusable. As a result, a toilet located in a summer cottage becomes a source of potential danger for the environment.

In order to prevent contamination of drinking water sources, it is mandatory to follow the rules governing the placement of sedimentation tanks. In particular, they contain requirements on how to properly dig a hole for a toilet (read also: "").

The minimum distance from the cesspool to the artesian well should be:

• on clay soils - 20 meters;
• on loam - 30 meters;
• in the presence of especially light soils (sandy and sandy) - 50 meters.

Soil characteristics have a direct impact on how quickly sewage will be absorbed by it. For example, highly clay soils often require regular pumping of accumulated effluents.

Sealed storage structures

They are various sealed tanks made of various materials:

• concrete;
• bricks;
• tarred wood;
• finished reinforced concrete products;
• plastic containers of various sizes.

It is necessary to dig a hole for the toilet with a slight slope to the neck of the tank in order to facilitate the complete pumping of sewage. The principle of operation of sealed sedimentation tanks is simple: household and fecal effluents enter the tank through a sewer pipe and, after filling it, are pumped out using sewage equipment.

Also, before digging a hole for a toilet, it is necessary to consider the possibility of free access of special vehicles to it for pumping out waste.

You need to know how to dig a hole for a toilet, observing the accepted placement rules for neighboring sites and some objects:

• distance to the border with neighbors - at least 2 meters;
• to a residential building - at least 5 meters.

The depth of storage pits should not exceed 3 meters, since with a larger size it is impossible to completely pump out sewage from a sealed container.

There is an important nuance here: in order to ensure the explosion safety of a sealed pit, it is necessary to have natural ventilation, which is equipped with a 100 mm pipe at a distance of 600 mm above the ground.

Its structural solution is as follows: sealed brick or concrete walls are laid out in a dug pit (or ready-made tanks are used) and bottom drainage is created using fragments of cinder blocks or bricks, stones, gravel and other materials. Such a filter performs a dual function: it not only mechanically cleans the waste liquid, but also creates the necessary environment for the growth of bacteria, which accelerate the decomposition of fecal waste.

Creation of a local sewer

The fastest, but most expensive option for equipping a sealed cesspool in a summer cottage is the use of factory-made plastic containers. Before properly digging a hole for a toilet, they decide on the size of the tanks. After that, they dig a pit and prepare the base for the container - a sand cushion or concrete.

To prevent the light tank from being pushed out by the movement of heavier soils, the plastic tank should be securely fastened to the created base. Then the tank is covered with earth and rammed. It is desirable to make the entrance of the sewer pipeline into the tank non-rigid and movable in order to reduce the likelihood of depressurization of the joint during natural soil settlement.

The second popular, but time-consuming method is the construction of concrete rings. Before digging a hole for a toilet, they are determined with the size of these products. You will need a truck crane to sequentially lower 3 rings into the prepared pit. They are usually 0.9 meters high and 0.7 to 2.0 meters in diameter. The joints between them are sealed with concrete mortar. From the inside, the structure is covered with bitumen and covered with a lid with a hatch for pumping sewage, and covered with earth.
