Plastic drainage trays with a grate are used in the construction of stormwater in the private sector, as well as in pedestrian areas with low traffic. Durable materials are needed for industrial facilities, highways, parking lots, gas stations: cast iron, concrete.

A plastic sewer pipe with a diameter of 50 mm is used for internal wiring of the drainage system, with the exception of the riser and connection to the toilet. Production materials: PVC, polypropylene, polyethylene, cast iron, steel. More often used polymer products due to the low weight and ease of installation.

The septic tank works on the principle of overflow from one tank to another of drains, which gradually go through several stages of treatment. Special bacteria are used to process sewage. In the final tank, through a pillow of crushed stone and sand, the liquid goes into the soil.

Plastic plugs for sewer pipes are installed to block the drainage in an emergency: if it is necessary to repair or replace part of the pipeline, to limit the operation of plumbing when paying for utility services.

To close the sewer pipe in the toilet, use plasterboard structures, plank panels, plumbing furniture, shutters or blinds. The choice depends on financial capabilities, location of communications, floor space.

Sewer pipes in a private house need to be insulated at very low temperatures in the winter and the inability to lay the pipeline below the level of freezing soil. For thermal insulation, mineral, streklo or slag wool, expanded clay, expanded polystyrene, polyurethane foam, foamed polyethylene are used.

Gray sewer pipes differ from red ones in strength, thermal conductivity, sound insulation, cost. The former are used for the installation of the internal drainage system, the latter for the external. The red color allows you to quickly find the pipeline in the ground if you need repair or dismantling.

Pressure sewer collector is installed in places where the relief and other features of the site do not allow to equip a gravity system. The flow rate of drains should be no more than 70 cm per second so that the pipelines self-clean.

The depth of the sewer pipe in a private house depends on the level of freezing of the soil, environmental conditions, and relief. If it is not possible to deepen the collector sufficiently, it is necessary to insulate the pipes, otherwise at minus temperatures the drainage system will stop working.

The compensator for the sewer pipe regulates the linear extension of the pipeline, gives the desired slope to horizontal sections of different materials, and is used to connect pipes with different sections. When choosing, you need to take into account the wall thickness of the pipes, their diameter and the length of the line.

The Grundfos submersible fecal pump is used to lift sewage drains vertically, to pump out fecal masses from a septic tank, to drain flooded rooms, to pump storm drains when gravity is not possible. The model is selected depending on the required power and operating conditions.
