Nuances and Subtleties of Autonomous Sewerage

There are two types of sewer systems: the first is central, the second is autonomous. The latter type of system is used in private houses or cottages; it is also advisable to use it in small industrial enterprises located outside the city.
All buildings located in the city are mainly connected to the public sewer system.

Wastewater from a bathtub, a sink, washing machines, a toilet bowl, a shower stall flows into it. Siphons and water seals are used to connect drain receivers and branch pipes. Their main purpose is to prevent unpleasant odors from accumulating in the room. Today, the sewer system is made using cast iron or plastic pipes, but PVC plastic pipes are most popular today. The pipes are connected by means of an O-ring, gluing or welding.

The autonomous sewage system used in private houses is also of two types:

septic system

storage tank system

To install a sewage system with a reservoir, a sealed pit is required into which all household water will drain. Autonomous sewage system Topas

is the most environmentally friendly, since special sewage machines are used to clean the pit. The disadvantage of this method is its cost, since the call for special vehicles is quite expensive. In addition, when arranging the pit, it is necessary to take into account the access roads for the car.

All autonomous sewage treatment plants can be divided into two types:

septic tanks

aerotanks

The main difference between the two types is the cleaning method. Using aerotanks cleaning processes are similar to those that occur in natural reservoirs. And when using a septic tank, water is purified directly in the ground. Experts in this field recommend using aeration tanks to treat large amounts of wastewater, and for smaller volumes it is better to use septic tanks.

A septic tank is nothing more than an ordinary horizontal sump. As a rule, this tank consists of several tanks, it is in them that the wastewater undergoes the purification process. Further wastewater treatment is carried out in drainage trenches or wells. During the operation of a septic tank, it is periodically necessary to pump out activated sludge from the tanks. When installing this system, it is necessary to use an individual approach, only with a competent design of the septic system can an optimal solution to the wastewater problem be achieved.
