Sewage pumping station. Types. Application. Working principle

Sewage management is an often overlooked but vital component of keeping a household running smoothly. In many houses and buildings, the central component of wastewater management systems, a sewage pumping station is essential to this process. It is imperative that both homeowners and property managers comprehend the various types, applications, and operational principles of these stations.

Let’s start by discussing the various kinds of sewage pumping stations. These stations are available in different configurations, each intended to meet particular requirements and situations. In both residential and commercial settings, submersible sewage pumps are frequently used and are submerged straight into the sewage tank or pit. Conversely, dry well sewage pumping stations are typically located in areas with limited space or high groundwater levels; they are installed above ground.

Let’s now investigate the uses for sewage pumping stations. These stations are essential in places where wastewater cannot be transported to the main sewage system or treatment facility by gravity alone. Waterfall conveying systems are widely utilised in residential and commercial buildings, as well as in municipal infrastructure, to effectively transport wastewater for treatment and disposal.

The functionality of a sewage pumping station can be better understood by grasping its underlying principles. In a nutshell, these stations work by gathering sewage from different locations, like sinks, toilets, and drains, and then pumping it to the main sewage system or treatment plant via pipes. Whereas dry well pumps use suction mechanisms to raise the wastewater, submersible pumps use impellers to do the same.

Purpose of the purification complex

The primary method of disposing of sewage is via sewage stations. The wastewater is directed to a higher level by the pump’s pressure, which causes self-flowing to proceed in the direction of the cleaning mechanism.

Pumping equipment might not be needed when sewage waste is in an independent drainage state. This is a rare exception that only applies to plateau regions. It is impossible to accomplish without the use of specialized technical equipment on uneven or hilly terrain. Consequently, the treatment process is made simpler by the use of technological devices.

The environmental performance of the area where the sewage pumping stations are installed is improved by the use of sewage pumping equipment. This implies that there is a lower chance of illness or discomfort for the local populace.

To prevent service personnel from coming into contact with the released liquids, the wastewater is transported in a unique, isolated system.

Main types of pumping stations

Domestic sewage treatment plants range in size from tiny to enormous. Similar systems, such as Grundfos Sololift2 home pumping stations, can be placed directly behind the drain tank and discharge liquids in the required direction. They take the shape of a cistern that is horizontally dug into the ground and has a capacity of several dozen cubic meters.

Apart from dimensions, CNSs vary in several other aspects as well:

  1. Type of installation: horizontal, vertical, with automatic pumps.
  2. Location type: above-ground, buried, partially buried.
  3. Type of system control: remote, automatic, manual.

Types of control

  1. Remote. Monitoring data is sent to a remote control panel. It is up to the dispatcher to decide which action to take.
  2. Automatic. The treatment system is controlled in a constant automated mode, with the help of special sensors located on or near the body of the system.
  3. Manual. Control over the equipment and the system as a whole is carried out by service personnel. They also control the filling of the tank.

Type of sewage

  1. Industrial. This type of cleaning equipment is made of a special durable material that can withstand chemical or thermal effects.
  2. Domestic. Installation of a sewage pumping station designed to function in standard conditions.
  3. Storm water. Such systems are equipped with additional cleaning equipment.
  4. Sedimentary. Such a station is mainly used in industrial areas, additionally treating sedimentary deposits.

Principle of operation of the sewage treatment plant

The lifting of wastewater and subsequent facility treatment is the fundamental idea behind the operation of the sewage pumping system. Pumping stations are also utilized in emergency situations.

With the help of four sensors that are mounted directly on or close to the pumping station, the majority of pumping stations run automatically.

  1. The mechanism is responsible for controlling small volumes of sewage. Which means that the pump does not have to be started.
  2. The sensor is directly responsible for starting the pump. Only after this, the sewage system starts pumping waste into the tank.
  3. The sensor ensures that the standby pump is started. Its activation means increased wastewater volume.
  4. The last sensor is activated in case of an emergency situation. This can occur due to the failure of one of the pumps, or when the device is unable to cope with the volume of liquid. In this case, the assistance of a special organization will be required.

When the level of sewage drops below the first sensor, the sewage pumping station system automatically shuts down. The sewage treatment plant will then run in a stable mode following that.

The primary thesis of the article on "Sewage pumping stations" is that these facilities are essential to the effective management of wastewater. There are several varieties of these stations, each designed to meet particular requirements in areas such as homes, businesses, or industries. They function by gathering sewage from pipes that are underground and raising it to a higher level with the help of pumps so that gravity can move it through the remaining sewage system. Maintaining appropriate sanitation and avoiding environmental pollution requires an understanding of the types, applications, and operating principles of these stations."

Maintenance of the sewage treatment plant

A number of specialized tasks are involved in maintaining the sewage pumping station, which helps to keep the system operating well.

Regular maintenance that supports the control and warning system, pipelines, and sensors must be continuously observed to guarantee the functionality of all plant mechanisms.

A minimal level of risk will result from following all of the equipment’s usage guidelines, which will positively impact the function.

Structure of the sewage treatment plant

The mechanism’s design ought to be assessed in a few fundamental variations:

Cleaning system for a private house

A collection of unique designs that are chosen separately according to the engineer’s recommendations.

Owing to its irregular dimensions, the apparatus might be subterranean. Such apparatus resembles a sealed container with pumps within. Fiberglass and plastic are used in the construction of the tank. The sewage pumping station’s service life is typically extended by fifty years when this kind of material is used.

Individual system components:

  • Plastic tank. Sometimes, such a tank is made on a metal or concrete base. But usually, plastic is the main material often used. Because it has a long service life, and allows you to replace the tank in the shortest possible time in case of need.
  • Fecal pump. If the station operates on a daily basis, such systems have an additional pump.
  • Plumbing (inlet and outlet)

Connecting the pumps and collector to the shared sewage system is essential. Reversing the flow of the liquid is prevented by a unique valve.

Automatic system with four sensors (floats)

Experts advise purchasing such a system regardless of circumstances because it is not costly. In the event that wastewater levels rise dangerously, each of them is capable of starting the pump.

Since the tank in question is submerged and connected to a drainage pipe, the working principle of this type of station differs slightly from that of a mini station. A sensor triggers the main pump and shuts off the network when the sewage reaches a predetermined level.

Compact mini stations (sololift)

A single piece of equipment that is chosen separately while considering several factors.

One can install a mini-station like this right in the house’s basement or bathroom.

The automatic system is activated (the motor is turned on) at the moment of liquid inflow. Next, a cutting mechanism pulverizes the liquid as it is pumped from the tank into the pipe. This avoids potential obstructions.

  1. Ladder for descending to the tank
  2. Special cabinet for controlling the system
  3. Additional filters
  4. Flow sensors
  5. Waste tanks

CNS calculation

First, the basic parameters of the equipment, capacity, and wastewater level (taking into account the inflow during one hour) are calculated for the sewage pumping station.

Specifications of the equipment:

  1. Tank volume
  2. Tank depth
  3. Number of working pumps
  4. Number of standby pumps
  5. Pipeline diameter
  6. Electric power supply

Parameters of performance:

  1. Required number of starting pumps
  2. Type of sewage system
  3. Differences in head elevations
  4. Use of a special control mechanism

Specialists should be given the prepared information based on the aforementioned parameters so that individual equipment components can be chosen. If you don’t, the sewage pumping system’s incorrect parts will break down, potentially creating an emergency.

Type Application
Submersible sewage pumps Used in residential and commercial buildings to pump wastewater from toilets, sinks, and drains to the main sewer line.
Grinder sewage pumps Primarily used in locations with tough solids like sewage from bathrooms or kitchens; they grind up solid waste before pumping.
Non-clog sewage pumps Designed for large-scale applications such as municipal sewage systems or industrial wastewater treatment plants; they can handle large volumes of waste without clogging.
Working principle Sewage pumps use impellers or blades to push wastewater through pipes. Submersible pumps sit in the sewage pit, while grinder and non-clog pumps can be placed outside the pit.

Maintaining effective waste management in residential, commercial, and industrial settings requires an understanding of how sewage pumping stations operate. When gravity is insufficient to move sewage from lower to higher elevations, these stations are essential. Sewage pumping stations guarantee the efficient flow of wastewater through the sewer system through a variety of types and applications.

Sewage pumping stations can be classified into two main types: dry well and wet well. Wet well stations have their pumps submerged straight into the sewage, whereas dry well stations have their pumps placed outside of the sewage tank. Every variety presents unique benefits and is chosen according to variables like available space, financial limitations, and particular project specifications.

Sewage pumping stations, no matter what kind, work on the same fundamental idea: they use pumps to lift sewage over hydraulic resistance and gravity to higher elevations. These pumps, which include grinder pumps, submersible pumps, and centrifugal pumps, can differ in their construction and workings. The amount of sewage, the distance it must travel, and the existence of solids or debris in the sewage all influence the pump selection.

Sewage pumping stations play a crucial role in ensuring appropriate sewage flow in regions with difficult terrain or inadequate slope for gravity-based systems. They guarantee that wastewater is constantly moving, avoiding backups, overflows, and environmental contamination. Homeowners and professionals can optimize waste management and promote environmental sustainability by making informed decisions by knowing the types, applications, and operating principles of these stations.
