The sewage elevator, also known as the sewage lifting station, is a drainage system consisting of a sewage pump, a water collection tank, a control device, and some related pipe fittings and valves. It is mainly used in various scenarios where wastewater cannot be discharged by gravity flow. Among them, the basement is the most common application scenario of the sewage elevator.
Nowadays, with the development of the economy and modern architecture, more and more developers and private residents have generated many new demands for interior design and use, such as adding new drainage units on the same floor of buildings such as large flat floors, office buildings, and shopping malls. Common situations include adding bathrooms and pantry in office areas, and adding bathrooms in households. Taking office buildings as an example, if the bathrooms on a certain floor are located far away or the current bathrooms are insufficient to meet the needs of the crowd, it is necessary to add new bathrooms. The user's request for same floor drainage is naturally due to limited practical conditions, as there was no planned drainage pipeline in the early stage, so it was not possible to lower the floor for drainage. The problem can only be solved by same floor drainage to meet the demand. At this point, the sewage elevator has demonstrated its outstanding advantages of supporting personalized decoration design and minimal damage, and has been widely promoted in the field of same floor drainage. So how does the sewage elevator solve the problem of same floor drainage?
It's actually quite simple. Since sewage cannot be discharged downwards, why not try discharging upwards! Same level drainage is the process of using the pressure of the water pump in the sewage elevator to lift the sewage from the newly added drainage point upwards, and then entering the main sewage pipe through a horizontal pipeline. The entire process does not require penetrating the floor slab and the working conditions are not complicated. Taking the same floor drainage of the newly added bathroom as an example, first we need to calculate the vertical height and horizontal distance of the drainage pipe from the original bathroom location based on the location of the newly added bathroom. Then lay pipes from the location of the newly added bathroom to lead the sewage into the original sewage pipeline. No matter what kind of scenario it is used in, the drainage method does not require smashing walls or re laying pipes, just connecting various pipes is enough.
Description of sewage lifting station
The integrated sewage lifting station is a system consisting of a sewage pump, a water collection tank, pipeline control, a filtration system, a control system, and pipe fittings and valves. Mainly used for raising low-level sewage, when the sewage in the basement cannot be discharged into the septic tank or municipal sewage pipeline by its own gravity, the traditional sewage discharge method is to set up a collection pit and supporting sewage pump in the basement. This traditional sewage discharge method is prone to blockage, regular cleaning, and environmental pollution caused by lack of sealing, with unpleasant odor, ultimately leading to the underutilization of the area. At the same time, once installed, the location can never be changed, which will have an impact on the future renovation and reuse of the house.
The sewage lifting device can easily solve all the above problems. It collects, stores, and lifts sewage into the municipal pipeline network, equipped with different water pumps according to different working conditions, which can meet the requirements of sealing, cleaning, flexibility, and efficiency. It can also specify inlet and outlet ports in different directions for customers, and output different remote transmission signals for customers to choose from.
The box is usually made of polyethylene PE material, with a fully sealed structure to block the emission of odors. According to the structure, it is divided into two specifications: In-built Sewage lifting station and External sewage lifting station. The external five-year-old elevator has better sealing performance.
how to choose suitable model ?
The premise is to understand the ultimate purpose of the product. The PE wastewater referred to here generally refers to the sewage generated in people's daily lives, which means that the amount of sewage generated is not very large, usually from daily activities such as bathing, toilets, laundry, cooking, etc., rather than rainwater, river sewage, etc. Product selection can be roughly divided into determining the flow rate as the first choice, followed by head, then power, and finally determining the installation location and volume.
- The determination of traffic is generally divided into two types
- One is calculated based on the maximum daily water consumption of residential residents, and the other is calculated based on the flow rate and equivalent of sanitary appliances. (The calculation method will not be detailed for now)
- The only thing worth noting is that based on the actual situation, the relative number of residents is relatively fixed. Generally, the calculated flow is multiplied by a coefficient of 1.1. In some public places or places with uncertain pedestrian flow, the flow multiplied by a coefficient is generally between 1.2 and 2.2, such as hospitals, shopping malls, subway stations, hotels, and other places. (If a household washing machine needs to be connected for sewage treatment, it is recommended to select a model with a capacity of more than 60 liters, because the model with a capacity of less than 60 liters can only be controlled by air pressure, and the foam in the sewage of the washing machine will affect the normal operation of the machine and cause damage; the model with a capacity of 60 liters and above has enough space to install the float switch and will not be affected.)
- The confirmation of lift, which refers to the location where the final equipment is installed, such as the basement. Either install equipment on flat ground or bury it underground. The first thing to confirm here is the relative height difference between the installation location and the ground, as well as the length of the pipeline that needs to be transported after leaving the ground. This is the key to confirming the head, no matter how the pump chooses the flow rate, the first thing to meet is the head. Otherwise, the water cannot be extracted. Confirming the length of the pipeline is to confirm the pressure loss along the pipeline.
- Total head=relative height difference between equipment and ground+pressure loss along the length of the pipeline+0.1 kg of outlet pressure (if the terrain is complex and there are many pipelines and valve bends, consider the safety factor appropriately. On the basis of the confirmed head, increase the head by 5-10 meters appropriately)
- Confirmation of power,After confirming the flow rate and head, a simple method is to confirm the power. Choose a pump that can meet the flow, head, and power requirements (referring to working environments with relatively low relative flow rates and low usage frequencies (where the flow rate generally does not exceed 5-10M3/h), such as households. Villas, or air conditioning condensate water, etc
However, in some work environments such as subway stations, shopping malls, and other large places with high population mobility, when choosing a water pump, a single pump can meet the requirements, but at the same time, a backup pump with the same parameters is also needed. In these places, the water pump starts frequently and works for a long time, so it is best to choose two pumps as one for use and one for backup (flow rate is generally between 10-50 m³/h) just in case. For sewage treatment in large public places, it is generally necessary to customize the selection according to actual usage needs.

In general, the effective volume is only 5% of the pump flow rate, which means that the pump can be started 15-20 times per hour to achieve the normal flow rate of the pump. The larger the reserve volume, the better, for example, taking the maximum value for a volume of 20-30 liters. This can alleviate the number of starts of the water pump and also provide a side protection for the water pump. But there may also be special situations in some places, such as high flow, small installation space, or low flow with large installation space. The first thing we need to do is to go to the site to investigate. Firstly, we need to discuss the installation size with the customer. At the same time, we also need to consider the maximum width for transportation into the workstation, such as when encountering narrow staircase turns in the basement or small room doors for installing equipment. The box can be divided into two or three parts for installation.
