Installation of a sewer pump. Sewage pumping station (SPS): types, device, installation and maintenance Installation of a sewer station in a private house

Sewage pumping stations (SPS) are special systems that serve to drain and deliver Wastewater to treatment facilities. Pumping stations are best used in places with low level collection of sewage when it is impossible to organize a gravity sewer network. The SPS installation allows you to discharge wastewater in difficult landscape conditions, regardless of the type of soil and weather conditions. Pumping stations can be used for pumping atmospheric, industrial and domestic wastewater.

KNS installation, advantages:

• scarce space is saved on the owner's site, since the sewage pumping station has small dimensions;
• when using KNS, the possibility of loss of pressure is excluded;
• does not require constant after-sales service by the experts. Is autonomous system, which, in the event of an emergency, is able to send a message to mobile phone owner;
• installing a prefabricated sewage pumping station is a fairly simple matter, since pumping station complete with everything necessary equipment, including - multi-socket branch pipes, which make it possible to connect pipes of different diameters to the pumping station.

Pump stations:

Visually, pumping stations are a vertically located cylindrical container made of polymer materials such as polypropylene. The installation of the sewage pumping station is carried out underground, and for its installation it is better to use the services of specialists.

When designing and building a sewage pumping station, one should take into account the features of the area and the amount of pumped liquid, as well as calculate the electricity that will be spent on the operation of the equipment. It is desirable that all necessary measurements performed by specialists, since the discrepancy between the data certain parameters may adversely affect the operation of the equipment. The installation of the sewage pumping station begins with the installation of the housing and pumping units, and ends with the connection of the equipment cables to the control panel. After that, the mandatory commissioning of the installation is carried out.

We offer professional and qualified installation of underground equipment, including various kinds KNS: fiberglass, polypropylene, polyethylene. The total depth of the product can reach 7 meters. And the diameter is two meters. The complexity of the work depends on the composition of the soil and the level ground water. In general, these works are hazardous and require special tool, special equipment and additional equipment. As a rule, JCB 4CX backhoe loaders are used for installation of sewage pumping stations up to 3.5 m deep. And for work at great depths, large JCB JS160 wheeled or tracked excavators are used. At high level groundwater is locally lowered by wellpoints.

Before performing work, you must carry out all necessary survey work: engineering drilling, soil sampling, determination of the appeared level and the steady level groundwater. After that, a project for the production of works is drawn up with reference to immovable objects, including horizontal and vertical sections of equipment at the locality. Before the start of work, an installation contract is signed with a work schedule. The site must be ready for installation and all necessary certificates of admission must be signed. Immediately after the completion of work and commissioning, we sign an act of acceptance and transfer of equipment and work with the customer. From this moment, warranty obligations for the work performed begin.

The cost of installation work

When calculating the cost of installing a complete sewage pumping station, the following are taken into account: the remoteness of the facility, the complexity of the operation of the equipment, the level of groundwater and the type of soil. In general, we can say that the installation of a pumping station with a height of 3 m will cost 35 thousand rubles, excluding materials and additional work. More accurate calculations any professional contractor will give only after leaving the site.

As a rule, the installation of an underground sewage pumping station includes:

• Excavation;
• Strengthening the walls of the pit, formwork;
• Installation of reinforced concrete slabs;
• Leveling the base with sand and tamping;
• Alignment of equipment on the level, anchoring;
• Backfilling.

If it is necessary to remove industrial or sewage effluents, a sewage pumping station should be installed. We will consider recommendations for the selection and installation of a sewer pumping station in this article.

General concept of a sewage pumping station

The main purpose of the sewer pumping station is the disposal of sewage water for sewage or household purposes. By design, sewer pumping stations are distinguished as simple, medium and complex.

The sewage pumping station consists of a sealed container to which a fecal pump is connected. The main function of the pump is to pump sewage waste to another sewer station or to recycling sites.

Sewer pumping station photo:

The sewerage station consists of:

• polypropylene container;
• submersible pumps;
• pipelines;
• pressure and outlet pipes;
• automation systems;
• ventilation systems.

Optional installation is possible:

• double reinforced bottom;
• thermal insulation;
• check valves;
• valves;
• service platforms;
• control panel;
• locking hatch;
• control sensor;
• choice of case material.

To service the sewage pumping station, a ladder is installed and a platform is equipped inside the tank. Hatches designed to close the glasses of the station in order to protect external environment from the smell.

The principle of operation of the SPS is that sewage water enters the SPS through a pipeline and enters the pumps. Installed on pipes check valves which prevent wastewater from returning to the system. Effluent is pumped through pumps for treatment.

The main functions and varieties of KNS

The main function of the sewerage station is the forced pumping of sewage and sewage water.

If complex relief areas do not allow you to equip a gravity drain, so as not to install deep collectors, it is better to purchase a sewer pumping station.

According to the pumped liquid, there are:

• sewer pumping stations of productive effluents;
• sewer pumping stations for household waste;
• SPS storm water;
• SPS of sedimentary runoff.

In accordance with the scope of application, there are:

• sewer pumping stations for the house;
• sewer stations of industrial type.

In accordance with the capacity, sewer pumping stations are divided into:

1. Mini sewer stations are small sealed container connected to the toilet, directly in the toilet or in the bathroom. Such sewer pumping stations are produced in various forms, color and design solutions. The mini-sewer pumping station is equipped with a fecal-submersible type pump, which is equipped with cutting mechanisms. The pump power is not more than 400 watts.

2. Medium sewage pumping stations are very popular, which feature a wide range of models. Such a station includes a polymer tank, which is installed in the ground, and a pump. The scope of medium-sized sewer stations is both domestic and industrial. In the domestic sector, one or two pumps are used, and in the industrial sector, only two. Pumps are used in a variety of ways: from models with elements that carry out multi-channel cutting operations for the processing of wastewater, to closed single-channel impellers. In industrial sewer pumping stations, the first type of pumps is not installed, because cutting models are unstable to stones or other strong objects. If a solid object hits the cutting mechanism knives, the pump immediately breaks down. This is a significant drawback of this type of pump.

3. Large sewer pumping stations are used in urban sewerage and drainage systems. AT large systems install the most powerful multi-channel pumps with impellers. Pumps with a cutting mechanism are not used in large stations.

When choosing a sewer pumping station, consider:

• depth of the supply system;
• the type and amount of fluid to be pumped;
• types of pumps;
• way to control the KNS;
• materials from which the KNS is made;
• diameter of the body of the sewer pumping station;
• KNS power.

Sewage pumping stations are made of polypropylene, fiberglass reinforced and polyethylene. These materials protect the station from corrosion and other external influences.

Pay attention to the internal parts of the KNS, it is better if they are made of stainless steel. In seismic areas, sewer pumping stations with a heavy-duty housing should be installed. AT northern regions it is necessary to carry out additional insulation of the SPS.

Take care to install vibration and leakage sensors on the pump.

Availability automatic system control will allow you to regulate the operation of the pump and organize the uninterrupted operation of the station.

Sewage pumping station project

To calculate the SSC, a number of actions should be performed:

1. Determine the flow of water. By calculating the minimum, maximum and average water flow.

2. Determine the pump head by adding the head height to the heating pipe losses and air losses.

3. Set a graph that will display common work KNS. The functional calculation must exceed the largest amount normal calculation.

4. Analyze the operation of the pump under extreme conditions.

5. Determine the volume of receiving containers.

Installation of a sewage pumping station

Before installing the sewage pumping station, a base must be installed, in the form concrete slab, minimum thickness which is 30 cm.

The body of the sewer station is attached to the slab with collet anchors.

KNS installation instructions:

1. Prepare the pit. In case of groundwater outlet, install a concrete foundation on the base of the pit.

2. Place the station on the foundation. Drill holes in the slab and install anchor fasteners.

3. Backfill the station with soil.

Advantages of installing a sewage pumping station:

• saving useful residential area;
• saving electricity;

• automated process;
• the need for a small number of personnel to carry out maintenance;
• low level of vibration and noise;
• mobility and easy installation;
• environmental friendliness;
• use in different climatic zones.

A sewage pumping station is used in cases where it is necessary to raise sewer drains and send them to the main sewer. In this situation, the task was to forcefully pump wastewater coming from the bathhouse into the central sewer with the help of the sewage pumping station. Initially, the customer wanted to deliver, but had to dissuade him, since TOPAS will not work if sufficient nutrition for bacteria does not get into it.

Real sewage pumping stations cost from 100 thousand rubles, we offered the customer an option similar to a standard sewage pumping station and made a non-standard one. In a standard sewage pumping station, 3 or more drainage fecal pumps with cutting mechanisms are installed. We installed one drainage pump with a knife inside the tube. Collector well Alta Plast Tuba a good option to organize the KNS with their own hands. This tube is a model Alta Plast Tuba - 2.400, 2 meters high, in fact 210 cm with a sealed bottom and a closing lid.

How to choose the right sewer pumping station

In order for the pumping station for your sewage to be as efficient as possible, you should select it carefully, guided by the criteria that we will outline below.

When choosing a station for your home, remember that there is absolutely no point in buying overly powerful and, therefore, significantly more expensive equipment, the capabilities of which will be used by a third or even a quarter. The selected unit must be optimal and fully meet the needs of your home. To this end, the following parameters must be taken into account:

1. The distance over which waste is to be pumped.
2. The maximum volume of processed wastewater.
3. The level of wastewater pollution and their structural and qualitative composition. So, if they contain large fractions, it makes sense to purchase such a KNS, which includes a chopper, which practically eliminates the possibility of blockages.
4. The height difference between the entrance of the station and the place where the effluents are supplied.
5. Equipment dimensions.
6. Required level of wastewater treatment.

There are no universal formulas used in calculating the performance of equipment. For this reason, you should use the calculation algorithm, which, as a rule, is set out in the instructions attached to a particular KNS.

The calculation of the required capacity of the station is carried out in the following sequence:

• the daily water consumption in the house and the volume of generated effluents are determined;
• an approximate schedule for the flow of effluents for a daily period is built;
• the maximum and minimum sewer flow values ​​are calculated;
• the required capacity of the pumping station is determined, taking into account the pollution of wastewater.

Having correctly determined the parameters listed above, you can accurately select the optimal equipment that will fully satisfy the needs of your home.

We have already talked about the price of sewer pumping stations a little higher. Now we want to clarify that the price is a fairly eloquent indicator:

• brand popularity;
• maintainability of the product;
• equipment service capabilities.

Preference should not be given to cheap units if their operation will be daily and if there is no additional pump equipment for evacuation and drains and there are no reserve tanks.

How to install KNS

To begin with, we deliver the materials and tools necessary for installation to the installation site. We begin to dig a pit under the sewage pumping station and ...

In parallel, we install a socket inside the tube to supply power to the fecal pump. A hole is drilled with a perk and a cable is threaded through the corrugation. The cable is mounted to the socket, and the socket is screwed onto the screws to the walls of the tube.

The outlet pipe is already in the trench and led into the central sewer, it remained to be connected to the station. We are digging a pit for the installation of a sewer pump station.

When the pit is dug to the required depth, in our case it is 225 cm, we make a sand cushion and level the bottom of the pit. We lay the guides for lowering the reinforced concrete slab.

By this time we are brought reinforced concrete slab, with which we will anchor our unit. Since the crane board could not physically enter the yard, we transported the slab manually, about 30 meters.

The reinforced concrete slab is in place, you can start lowering the tube into the pit.

Another good thing about the tube is that it is light because it consists only of plastic, we easily lowered it and installed it in place. Further, with the help of a cable, the tube was securely fixed to the reinforced concrete slab. Now you can start the outlet pipe (HDPE 32) and start burying.

The tube is buried, of course, with sand so that the backfill is dense. An electrical cable is laid in a trench.

For tie-in supply sewer pipe in the body of the station was needed to drill a hole for the jigsaw blade and myself. A circle was cut and wound up with a rubber seal.

It remains only to dig ...

pumped out the incoming drains.

KNS closed with a lid.

The outlet pipe HDPE 32 in the house is led into a 50 gray sewer pipe through a transitional rubber band, which provides secure fastening and tightness.

In general, the customer was satisfied with the work done, and promised to recommend us to his friends.

This instruction is suitable for all housings of SPS (polyethylene, fiberglass) of underground execution

See standard projects and KNS schemes

Before installing the KNS, it is necessary to properly prepare the base. When developing soil mechanized way, with the help of an excavator, the pit should not be slightly modified to the design mark, in order not to violate the natural integrity of the soil. The completion of the soil to the design mark must be carried out manually, avoiding digging, in order to concrete base under the sewage pumping station was mounted on the mainland soil.

Procedure

1. It is necessary to clean the surface of the bottom of the pit from foreign objects.
2. At the bottom of the pit, around the entire perimeter, sand cushion 200 mm high with watering and tamping. According to the developed drawings, a formwork for a reinforced concrete base is assembled. Several layers of mesh are mounted into the formwork, made of reinforcement of various diameters and different step mesh (as a rule, the mesh is made with a step of 100x100 mm from reinforcement Ø 10-12 mm, in 2-3 layers, depending on the height of the concrete base and the size of this base). The dimensions of the bases for the sewage pumping station are developed by design organizations depending on the size of the sewage pumping stations, the composition of the soil at the installation site of the sewage pumping station and the availability of groundwater at the installation site. Next, the formwork is poured with concrete and allowed to settle. AT various occasions different grades of concrete are used. In dry soils, grades M150 are used, and in moisture-saturated soils, moisture-resistant grades of hydraulic concrete M200, M 250 Concrete works must be carried out in accordance with all the rules of concrete work technology.
3. After the concrete has gained strength, the installation of the KNS hull begins. Before mounting the KNS body on the base, clean the surface from foreign objects.
4. When lowering the body into the pit, distribute the load from the mass of the body evenly over all mounting loops.
5. The plastic housing must be mounted strictly in the design position. After the body has been installed to the design mark, it is necessary to make sure that it has no damage and is installed strictly along the design axes. Check the verticality of the body. With a horizontal foundation, the KNS will stand vertically.
6. After installing the pumping station on a concrete base, holes are drilled around the entire perimeter in the skirt of the pumping station (8-12 pieces, depending on the diameter of the station) with a diameter of 12-16 mm, a length of 18-22 mm) for installation anchor bolts. After that, the bolts are inserted into the holes, clogged and tightened.
7. At a high level of groundwater, in addition to fixing the sewage pumping station with anchor bolts, to a concrete base, it is necessary lower part KNS, approximately 0.5-0.8 m pour concrete. The calculation of the weight of concrete is carried out in the scope of the working draft or the project for the production of works.
8. After fixing the SPS to the concrete base, backfilling sand, layer by layer with tamping and watering to the level of the inlet and pressure collectors. Before backfilling, make sure that the SPS housing is not damaged. After installing the SPS on the base and checking its verticality, start backfilling. (Sandy backfill serves as a gasket between the SPS body and undisturbed soil and serves as a protection of the SPS from soil movements).

1. Then the pipes of the incoming collector are connected and the pipes of the pressure branch are connected. The soil under the supply and pressure collectors is rammed.
2. Then backfilling with sand is carried out in layers, to the ground level with layer-by-layer tamping, evenly over the entire diameter of the sewage pumping station. If these conditions are not observed, the body or neck may be deformed.
3. Then the pumps are installed in the housing of the KNS. The lowering of the pumps along the guides in the SPS can be done manually (if the pumps have a small mass) or using lifting devices type of hoists or cranes (if the pumps have a large mass).
4. Then it is mounted. The pump control cabinet, according to the project, can be placed on the housing of the pumping station in a special metal box (protection against vandals), near the pumping station in a metal box or in any room located close to the pumping station. It is easier and cheaper for everyone to place the pump control panel on the pumping station housing. At our production facility, we have developed platforms with sealed inputs to the sewage pumping station, for the installation of metal boxes inside which there are pump control cabinets. Electrical cables from pumps in the standard have a length of 10 meters and if the pump control cabinet is not located near the sewage pumping station, then it is necessary to buy an imported, expensive cable for extension, which increases the cost of installing the pumping station.
5. The next step is to connect the central cable to the pump control panel. The cable is selected depending on the power of the pumps and according to the project for the installation of the sewage pumping station.
6. Then, hanging floats are hung inside the SPS for the operation of the pumps.

At the final stage of the installation of the SPS, cables from pumps, from floats, from overflow sensors, etc. are connected. to the pump control panel and commissioning of the KNS is done.
