What is pressure sewerage?
Pressure sewerage is a system 
sewage, in which sewage is pumped using pumps to higher ground levels or to central collection points. Unlike gravity sewage, the flow of sewage is not dependent on the terrain, the number of obstacles, the length of the pipeline or the connection solutions used to ensure an appropriate slope.
The undoubted advantage of such a solution, apart from greater freedom of sewage flow, is the fact that the installation of a pressure sewage system does not exclude cooperation with negative pressure and gravity sewage systems. It is only important to use an expansion chamber equipped with ventilation at the point of contact of the pressure sewage system with other sewage systems. The procedure is intended to prevent unpleasant odours from escaping outside the chamber.
The design and implementation of pressure sewage systems ensures:
- greater freedom in laying pipeline routes;
- ability to cross terrain obstacles;
- allows you to limit the depth of excavations necessary to lay pipes.
How is pressure sewerage constructed?
The efficiency of pressure sewage depends to a large extent on the correct selection of its components, as well as the quality of the structural elements used. An important part of the system is the external sewage system , located outside the main cleaner. It is used to build a network of pipelines, usually designed in a branched or ring form (applies to the connection of several buildings to a single domestic sewage pumping station).
The condition for the functioning of the pressure sewage system is the failure-free operation of submersible sewage pumps, which, in cooperation with the device grinding solid contaminants, maintain the required pressure in the pipes, allowing the flow of sewage. The pumps are installed in pumping stations, regulating the flow of sewage depending on demand and distance.
Pressure sewerage uses pressure tanks to collect and balance the flow of sewage. These tanks help maintain a constant pressure in the system and ensure stable operation of pumps.
It is impossible not to mention control elements such as non-return valves, control valves and pressure sensors. By monitoring and controlling the flow of wastewater, it is possible to maintain optimal operating conditions of the system.
Pressure sewers are primarily used in densely built areas where the traditional gravity system would be insufficient. These systems are effective in transporting sewage over longer distances, in areas with varied topography and when it is necessary to overcome obstacles such as hills.
It should be noted that the details of construction and operation of a pressure sewer system may vary depending on the specific project and the requirements dictated by the conditions prevailing in a given area.
Products necessary for pressure sewage
Great interest in sewage systems 
pressure sewage systems owe, among other things, lower construction costs than in the case of conventional sewage systems. Let's check what elements are the components of the system?
1. PVC and PE pressure pipes used in pressure sewage systems are more resistant to high pressure and pressure resulting from the transport of pollutants.
2. Valves allow you to control the flow of sewage and regulate the pressure in the network. The following are used in installations:
- ball valves;
- check valves;
- reducing valves;
- control valves.
3. Pumps generate the required pressure to support the flow of contaminants in the network.
4. Pumping stations are built in larger pressure sewage systems. These are facilities where pumps and other necessary equipment are placed, responsible for mixing sewage from lower points to higher ones or to sewage treatment plants.
5. The controllers and sensors that are fitted to pressure sewage systems monitor and control the operation of the system. Among them, the following are worth noting:
- pressure sensors;
- level sensors;
- flow sensors.
- And other devices whose task is to provide ongoing information about the status and operation of the network.
6. Mounting accessories are essential for the installation and maintenance of pressure sewage systems. They include, among others:
- PVC, PE pressure fittings ;
- connectors;
- reductions;
- knees;
- clamps;
- seals.
Before starting to build or modernize a pressure sewage system, it is always worth taking advantage of the opportunity to consult a representative of a reputable supplier of sewage systems. This will allow you to select the right materials and apply optimal technological solutions, ensuring many years of trouble-free operation of the pressure sewage system.
