The easiest way to set up a central sewage on the site of similarity is to construct a drain hole for sewage yourself. Its arrangement can be divided into several stages.
At this stage, it is necessary to make calculations - what size should the drain pit equipped with its own hands be, should be determined the number of people whose accommodation is planned for the suburban area. The volume of the drain hole directly depends on the intensity of use of various plumbing fixtures.
This will work the drain hole
In addition to the size selection, you must determine where exactly the drain hole with their own hands will be organized. The following rules should be followed:
After choosing the location and volume of the drain hole, primary earthwork is required. Digging a pit under the drain hole for a small family is not so difficult.
Digging out a pit under a hole
The construction of a pit depends on whether you plan to concrete the walls of the drain pit or not. Sealed sewers will require regular cleaning of the pit from waste with the help of the waste disposal service, as well as the drain pit without concrete bottom.
At the bottom of the prepared pit should be laid drainage - sand and gravel pad. It will be including the water filter, gradually leaving the ground. When concreting, a layer of sand and gravel can be made small - up to 10 cm. However, if such a pillow is planned as a natural filter, its thickness should not be less than 20 cm.
Concreting of the bottom is carried out using concrete mortar and reinforcement. On the prepared sand-gravel cushion, a layer of mortar is laid out in 5-10 cm, into which the reinforcement grate is embedded and another layer of concrete mortar is added. If you plan to use concrete rings for a sealed drain hole, you should deepen the walls while arranging the bottom so that the diameter of the bottom of the drain hole becomes larger than the diameter of the hole for the sewer hole.
With a concrete bottom and without a bottom
After arranging the bottom of the pit, it is necessary to proceed to the formation of the walls. You can use:
Drain pit from concrete rings
In the event that it is planned as walls put concrete rings, you should equip the drain hole as follows:
Concreting the walls in the home will require not only the production of cement mortar from cement of a grade not less than M200, but also the construction of formwork from wooden planks. For greater strength, be sure to add reinforcement - metal rods with a thickness of at least 1 cm.
Walls can be built from broken brick
The drain hole, the walls of which are brick masonry, is not necessarily equipped with a whole brick. Broken bricks, connected with cement mortar, will fit perfectly for the organization of sewage of a private house.
During the construction of the drain hole it is necessary to provide for the discharge of sewer pipes from the house.At the top of the tank, a hole with a diameter slightly larger than the drain pipe should be made. The void between the pipe and the walls of the hole is filled with sealant.
Lid for the cesspool
A sealed lid with a hatch should be placed on the prepared drain hole.
