A red sewer pipe with a diameter of 150 mm is used to transport effluents from the house to the septic tank, provided that the water flow is not more than 100 liters per day. Gray pipes are used to connect the toilet and the riser device inside the building.

Plastic pipes for domestic sewage are made of polyvinyl chloride, polyethylene, polypropylene. The diameter is selected depending on the destination. Outlets from sinks, household appliances, bathtubs, showers - 40-50 mm, for toilets and risers, the recommended diameter is 110 mm.

Revision wells for sewage systems are installed in places of turns, branching of pipes, transitions from one diameter to another, and differences in height. The design is needed to check and repair the line in case of leaks or blockages.

The arrangement of the cesspool depends on the volume and composition of the effluent. For sewage from the toilet, sinks, household appliances, a sealed construction should be done so as not to infect the environment. The material used is plastic, concrete rings, brick.

To properly make a sewer pit in a private house, you need to calculate the amount of water consumed, take into account the location of buildings, plantings, a source of water supply, the level of groundwater. It is important to follow sanitary norms and rules, otherwise you can infect drinking water with sewage.

The reasons for the smell of sewage in the bathroom are blockages, violation of the design of the water seal, improper assembly of pipes, depressurization of the mains, poor ventilation. It is impossible to put up with this situation - the evaporation of effluents is harmful to health. It is necessary to check the system, if necessary, call the plumbing.

The construction of a sewer well made of concrete rings is an inexpensive option for a septic tank for giving. The difficulty lies only in the large weight of the products - to install the rings you need a special technique. Joints must be carefully sealed. The location of the well is determined in accordance with sanitary norms and rules.

You should also decide whether the unit will be needed for other purposes. Submersible models are more powerful, but you cannot get and transfer them from place to place.

Calculation of the sewerage system for a private house includes designing the location of the system, choosing the cross-section and material of the pipes, calculating the optimal slope of the pipeline, the volume of the septic tank, and the size of the shower trays. It should be guided by the recommendations of SNiP and take into account the peculiarities of climatic conditions.
