Drain pit and its arrangement

The operating principle of the waste pit

Modern country and country houses are very different from old buildings.

Tenants are gradually changing wooden toilets in the yard for comfortable toilets, installing shower cabins in the house, baths, useful household appliances.

But in the absence of a central sewer system, the question of where the sewage dirty water should flow is usually solved in the simplest and most convenient way.

Installed drainage pipes, through which water drains into the pit, which is outside the house on the site.

The most common cesspit is the storage device, which is known from very old times, it can be equipped very quickly in many ways, for example, with the help of concrete rings, bricks, tires and much more.

When filling a pit, waste and sewage from it are pumped out using specially equipped equipment.

For people who choose to go out of town mainly for the summer season, the simplest and cheapest way is to use a drainage pit with their own hands, especially since it is usually made from the simplest materials available, and such a setup takes only a couple of days.

The location of the future pit

So, when you decided to make a drainage pit, the first thing you need to determine the location of its location, since there are special regulations on this:

• The drainage pit in a private house should be located only in the adjacent territory;
• The device of such a pit should be at a distance of 10 meters from the foundation of your structure and other structures, including those located in neighboring areas. Due to the proximity of the location of the leaky drain hole, destructive processes in the foundation, located near houses and other buildings, are possible;
• Also the cesspool should be located no closer than 1 meter to the fence;
• The depth of the pit must be no more than 3 meters. It is important to take into account the level of occurrence of groundwater;
• The pit arrangement should be no closer than 30 meters from drinking wells;
• If the site has elevations, then the pit must be built in the valley;
• pumping drain pits should take into account the possibility of access to it special equipment.

Determine the future volume of the pit

Before deciding on the type of future pit, it is necessary to decide what dimensions will be in the drain drive. The volume must be calculated with the terms of use of water resources in the house.

If the dwelling is the permanent location of the whole family, then the drive must be provided for a lot of sewer outlets.

But if your site is only for recreation in the summer season or on weekends, then the well may have a smaller volume.

Everything here counts, starting with the number of people having a rest, before calculating whether a drainage pit for a bath will be used.

Calculating the volume of the cesspool, take into account also the accessibility of the access to the suction machine to it, taking into account that the pumping services are paid, with frequent use of water resources and a small volume of your pit, it fills very quickly, so a frequent call will fly you into a "penny".

Cesspit with brick

The most accessible and easy way to arrange the walls and the bottom of the drainage pit is to lay them with masonry.

This system has a number of its pros and cons, consider them in more detail.

Advantages of the brick drainage pit:

• environmentally friendly - the pumping out of the drain pits made of bricks is quickly and easily done with a special sewage machine;
• independence from seasonal fluctuations of groundwater;
• does not pollute the surrounding soil, since a large volume pit is equipped with a bottom and fenced from all sides;
• ease of construction - such a pit quickly and without great physical costs can make a person who does not have building skills, with minimal knowledge.

Minuses of the brick drainage pit:

• The appearance of an unpleasant odor when the pit is filled with draining water. This will help to cope with the timely cleaning of the drive;
• Fragility - under the influence of an unfavorable environment, the brick lends itself to destruction. Thus, the average life expectancy is about 15 years;
• Cost of cleaning. A brick pit requires a sewage machine to be called once or twice a month on condition of permanent residence, this will avoid accumulation of sludge at the bottom, which in the future will greatly complicate the cleaning of the drive.

Required construction tools and materials

Before starting work, you need to take care of the necessary tools and materials:

• shovels - shovel and bayonet;
• measuring tape;
• level;
• buckets for carrying the earth;
• staircase;
• sand;
• cement;
• crushed stone;
• bricks;
• reinforced bars;
• ruberoid.

The consumption of building materials depends directly on the volumes of the future pit.

Construction of a drain hole made of brick

The first step is to excavate a pit. This can be done in two ways, with your own hands or with the help of an excavator.

The second way is much more expensive, but it will help you to save considerably time and effort.

Usually the pit is made not more than a meter wide, the length is chosen in accordance with the volume of future wastewater. The top layers of the excavated land can be left to fall asleep in the garden.

After you dig out the pit, it is necessary to fill the bottom with sand with a layer of approximately 15 centimeters, on top of it lay a layer of concrete of the same thickness.

On top of it, the screed is still layered 2-3 centimeters from a sand-cement mortar. Of course, the best option is to place on the bottom of a reinforced concrete slab with a slope of 45 degrees.

The bricks are laid in staggered order, fixed with a mixture of sand and cement.

It is possible to produce a plaster over the masonry, for a long service life it is possible to lay a layer of reinforced mesh, over which plastering will be carried out.

Do not forget to make the ventilation system, this is perhaps the most important stage.

Why is it so necessary to equip ventilation?

To have an outflow for the emission of methane gases, which fill the pit in the decomposition processes. Ventilation is carried out through a hatch opening or an additional vent pipe is installed.

Drain pit device with concrete rings

Mounting of the pit with concrete rings is carried out in this way.

If you intend to use concrete rings without a bottom, then first you need to fill the bottom of the pit with a mixture of gravel and cement, about 10 centimeters thick.

After complete hardening, the resulting cracks must be additionally filled with cement mortar.

The installation of concrete rings is carried out quickly with the help of special equipment, if it is not possible to attract it, then it can be laid manually with the obligatory help of other persons.

All joints of concrete rings must necessarily be sealed. It is also possible to additionally make waterproofing of concrete rings and the bottom of our pit.

Before laying pipes, it is necessary to make holes for installation inside the concrete rings.

Trench for pipes must be dug at least a meter deep to avoid freezing to minus temperature. Also, the slope of the pipes should be about 3 percent.

Drain pit of tires

If the drainage pit in the country or a site is planned for a small volume, then the cheapest and easiest way of installation will be a drain hole with its own hands made of tires.

It is usually necessary about 10 tires, which can be found for free in virtually any tire fitting.

When the pit is prepared, a hole is made in the center of the garden drill so that the waste water can seep through the soil layers after the pit is filled.

A drainage pipe is installed in this hole, it should be placed approximately 1 meter above the bottom of the drain pit so that it does not get clogged by large waste waste.

The bottom of the pit must be covered with a layer of gravel about 10 centimeters. After these steps, you can begin to lay tires, you must first cut the inner part.

The joints formed between the tires must be sealed, and the voids between the tires and the walls of the pit itself are covered with clay.

After this, it is necessary to install a pipe, which will drain drains. The drain pit of tires is quite a popular option.

Pit with drums

When digging a pit for a barrel, you need to do it 15-20 centimeters more than the diameter of the container.

The bottom of the pit is covered with a layer of sand, which is 15 centimeters, if the ground water is very close to the surface, it is necessary to make a screed from a solution of sand and cement.

After the cushion is ready, you can start the installation of the barrel in the pit. The remaining land will go to fill the cracks around the walls of the pit and the barrel. But such a sink is filled very quickly.

This article on how to properly make a drainage pit is completed. Guided by all the rules and tips, having looked at the photos of the instructions, it would be easy to build such a system on their own.
