A centralized sewage system is a complex and rather bulky system. Pilometers of pipes stretch from collectors to each house and toilet in every house. Pumps, cars, containers and maintenance staff do not always cope with clogs and accidents. Therefore, it is better to solve all problems on your own. And ideally – not to allow clogs, failures and interruptions. The sewage and pumping station, or KNS, independently and in time will save a person from problems with wastewater and the consequences of rainfalls and floods. For good KNS, even during the flood, there is a job!
The standard sewer station of the KNS is equipped with several pumps, solid garbage crushing, control cabinet and shut-off tribe armature. All this is placed in a plastic shaft and removed away from the eyes of human. The length, or rather the depth, such a structure ranges from several to 10-12 meters, and the diameter reaches 3 meters.
So that it is 100% sealed, the case is best made of plastic. Polypropylene, polyethylene, fiberglass and their analogues dignifiedly proven themselves as building material for various needs. The fact is that the plastics are chemically and electrically inert. That is, neither aggressive drains of fecal masses, nor industrial waters will harm the KNS. Alkali, acid, salt, high and low temperature will also retreat before such an obstacle. Corrosion of metal products and cracking of concrete remained in the past. Now wherever possible, these building materials are intensively replaced with plastic. And where it cannot be replaced due to a non -stop process, there is a lining and plastic inserts there.
The KNS sewer station most often has two submersible pumps. They can be taken to the surface, but then the question of cooling working mechanisms will arise. And there will be more noise. And when all parts of the KNS are underground, then people do not even know what a useful work is being busy with the sewer station.
Equip industry and residential areas, where gravity circulation of waters is excluded or difficult to exclude or difficult. It also happens that the soil freezes and you have to take additional funds to ensure timely output of dirt. Each city has one or more KNS as part of its utilities. But local stations are better because in case of stopping one of them, its functions can take on another.
