When constructing a private house, the future owner often raises the question of how to properly arrange the sewage system. After all, amenities on the street are far from the best way to make your home comfortable.
The simplicity of its use and maintenance in the future depends on how correctly the sewage project is chosen. To arrange this engineering system, like most others, is best already at the construction stage. In a finished house it will be a little more difficult to carry it out, because such work is often associated with breaking open floors, making appropriate changes to the foundation of the house, etc.
Sewer design should be developed in compliance with all relevant norms and rules. In private homes, an autonomous sewage system is most often arranged. Usually this is due to the fact that in villages and towns centralized communications are a rare phenomenon, and therefore, in fact, there is nothing to be connected to.
In this case, a cesspool is arranged , which should be at least 5 meters from the living quarters. Its volume for private homes averages 1.5 m3. When installing a sump, it should be possible to access the machine-wastewater.
In addition, the sewerage of the house should be designed in such a way as to exclude the interaction of wastewater with tap water. There are several other important points that you need to consider when designing a project. Firstly, it is not allowed to carry sewer pipes on the ceiling of living rooms. You can also not lay them in the walls and floors of living rooms, bedrooms and kitchens.
The main elements that include any sewage project are the riser and pipes connecting it with objects intended directly for use (sinks, toilets, bathtubs, etc.) There are certain standards by which the thickness of the riser and pipes in that case if toilet bowls are connected to them, it must be at least 10 cm. In other cases, at least 5 cm. The slope of the downpipes towards the drain water drain must be no less than 0.033 g.
Sewer systems are arranged using cast iron, steel, plastic pipes. Previously, cast iron products were mainly used for this purpose. They are quite reliable and durable. Nowadays, plastic pipes can be called more popular. In addition to reliability, they also have a number of advantages - the ability to absorb noise, ease of installation, resistance to the effects of the most common chemicals, etc. The only thing to consider is the exposure of polypropylene and polyethylene to UV rays. It is better to conduct such pipes covertly - inside floors and walls.
It is best if the sewage project will be developed by specialists. However, for a small house, it is possible to draw up a plan for the sewage system independently. It is only necessary to take into account all the rules and requirements provided for in this regard. If everything is done carefully and thoughtfully, the sewage system in a private house will last for many years without creating unnecessary problems for the owner.
