To sewer in a wooden house, you need to take into account the possibility of subsidence of the building, plan the installation of bathrooms, sinks, household appliances, choose a septic tank. It is necessary to be guided by the requirements of SanPiN 2.1.4.1110-02 and SNiP 2.04.03–85.

The sewage system in a private house with a high level of groundwater involves the use of sealed tanks that are not subject to corrosion. To prevent the septic tank from floating, you need to fix it with anchors to the concrete base.

In order to properly lay the sewers in a private house with your own hands, you need to make a drawing, mark on it all the bathrooms, sinks and household appliances, calculate the location of the septic tank, the slope and the diameter of the pipes, take into account all the turns and branches.

Sewer pipelines are divided into external, internal and drainage. External most durable, as they must withstand temperature extremes, soil pressure. Drainage are designed to remove rain and melt water from the site. As a rule, they are corrugated and perforated.

Storage tanks for sewerage in the country are made of plastic, metal, concrete, fiberglass. Plastic is the most popular since it weighs little and is inexpensive. Septic tank must be installed at a distance from buildings and drinking wells according to SanPiN.

A sewer pipe is a special extension from one end of the pipe into which the standard end of the next element is inserted. The method of sealing depends on the material. Plastic are connected using special glue or o-rings. Cast iron, ceramic and asbestos-cement - chasing.

Cast-iron socketless sewer pipes are used in the installation of a central and private collector. Distinguish between internal and external elements, each of them is used strictly for its intended purpose. Products with any defects are prohibited for use.

The cesspool can be metal, concrete, or plastic. Plastic is lighter, cheaper, not susceptible to corrosion, durable, so it is chosen more often. When installing the tank, sanitary standards and the quantity of wastewater must be taken into account.

An internal exhaust in the sewer is necessary to prevent unpleasant odors and protect residents from methane poisoning, which is released by human waste products. External ventilation prevents air dilution in the septic tank and reduces the likelihood of odors entering the house.

Insoluble particles settle in the sewage treatment tank, after which the clarified liquid enters the next compartment of the treatment plant for processing. The principle of operation of structures can be different, one goal is to obtain safe water for the environment at the outlet.

Living bacteria for septic tanks and cesspools process all organic sewage and eliminate unpleasant odors. At the exit, carbon dioxide, water and sediment are formed. Water can be used for domestic needs.
