Working documentation: from 22 days
Price from 50000 roubles
An incorrectly selected pump, an underestimated volume of the receiving tank, or the absence of a backup unit - and the pumping station does not pass expert review, and the facility is stopped at the approval stage. AYU-Project develops design and working documentation for pumping stations for any purpose - water supply, sewerage, fire extinguishing, pressure boosting - for residential areas, industrial enterprises and infrastructure facilities across Russia. Hydraulic calculations are performed in specialized software with a standard reserve of 10-15%, the layout of the machine room is based on safety requirements, passages and maintenance. The price and terms are fixed in the contract, the comments of the state expert on the section are eliminated free of charge.
What is included in the design of pumping stations?
The design of a pumping station covers two stages - design documentation and working documentation. The DD stage substantiates technical solutions and undergoes state expert review; the WD stage provides builders with comprehensive installation data down to equipment part numbers.

- Drawings of the turbine room drainage system
- Specifications of equipment and materials with manufacturers' articles
- Bills of quantities in PDF and DWG formats
What types of pumping stations does AYU-Project design?
AYU-Project designs pumping stations of all main types - from compact booster plants to large sewerage stations with a capacity of thousands of cubic meters per day. The type of station determines the reliability category, redundancy scheme and composition of calculations.
| Station type | Purpose | Reliability category | Key standard |
|---|---|---|---|
| VNS (plumbing) | Water supply to consumers | I-III | SP 31.13330.2021 |
| Sewage station (sewage) | Wastewater pumping | I-III | SP 32.13330.2017 |
| PNS (fire) | Water supply for fire extinguishing | I | SP 8.13130.2020 |
| Increasing | Maintaining network pressure | I-II | SP 30.13330.2020 |
| Drainage / storm water | Drainage of groundwater and rainwater | II-III | SP 32.13330.2017 |
Water pumping stations (water pumping station)
Stations of the first, second and third lift for residential areas, industrial enterprises and suburban complexes. AYU-Project engineers calculate operating modes for peak and night water consumption, select frequency converters to smooth out the load curve and determine the necessary redundancy of units according to SP 31.13330.2021.
Sewage pumping stations (WWPS)
Pumping of domestic and industrial wastewater to treatment facilities. AYU-Project calculates the volume of the receiving tank for maximum inflow, selects submersible pumps taking into account the composition of the wastewater and provides protection against blockages, gas release and corrosion. For industrial facilities, the chemical composition of wastewater and the explosion protection class of equipment are additionally analyzed. SP 32.13330.2017.
Fire pumping stations (FPS)
The first category of reliability according to SP 8.13130.2020 - any interruption in water supply is unacceptable. AYU-Project calculates hydraulic parameters for the conditions of sprinkler and deluge installations, provides for automatic start-up from the AFAS signal, duplicate pipeline lines and installation of pumps “under the flood” where technically possible.
Boosting and drainage stations
Boosting stations are used in high-rise residential buildings, shopping centers and medical institutions when there is insufficient pressure in the main networks. Drainage and stormwater stations ensure the removal of water from underground parking lots, buried structures and from the territory of objects. In both cases, AYU-Project designs frequency regulation and automatic maintenance of specified parameters.
How is the hydraulic calculation of a pumping station performed?
Hydraulic calculation is a key design stage, on which the type and power of pumping units, pipeline diameters and redundancy scheme depend. An error at this stage leads to the fact that the station either does not provide the required pressure, or operates in off-design mode and quickly fails.
AYU-Project engineers perform calculations using specialized software - Zulu Hydro And WaterGEMS - which allows you to simulate the operation of the station in all modes: maximum water consumption, fire mode, night minimum. The calculation includes:
- Determination of the calculated flow rate and required pressure, taking into account losses in pipelines
- Selection of the pump operating point based on the combined characteristics of the pump and the network
- Calculation of water shock in case of sudden shutdown of the pump and selection of protective measures
- Checking the NPSH and determining the permissible suction head
- Calculation of energy consumption and selection of the optimal frequency control mode
All results are checked with a standard margin of 10-15% for productivity and pressure - this eliminates the situation when the actual parameters of the network after construction deviate from the design ones.
What are the most common mistakes in the design of pumping stations?
Most problems in the operation of pumping stations arise at the design stage. AYU-Project records typical errors and eliminates them through internal regulatory control and verification of calculations.
- Selection of a pump without analyzing all operating modes. The pump is selected for the design maximum, but is not checked in the night-time minimum mode - as a result, the unit operates in the off-design characteristic zone, vibration and accelerated wear appear.
- Reduced volume of the receiving tank WWPS. The reservoir is calculated without taking into account peak inflows and the required number of pump starts per hour - the station operates in frequent start-up mode, which reduces the service life of the equipment.
- Lack of protection against water shock. A water hammer absorber is not included in the project “for the sake of economy” - in the event of an emergency shutdown of the pump, the pressure in the pipeline increases abruptly and damages the fittings and pipes.
- Incorrect selection of fittings. At the outlet of the pump, shut-off valves are installed instead of control valves - they are not designed to regulate the flow and quickly fail.
- Insufficient layout of the machine room. The passages between the units do not meet regulatory requirements for SP 31.13330.2021 - maintenance and replacement of equipment becomes impossible without dismantling adjacent equipment.
- Errors in the automation system. Emergency settings are set without reference to the actual characteristics of the pumps - the protection system is activated in normal operating modes.
What should you consider when integrating a pumping station with other facility systems?
A pumping station rarely operates in isolation - it interacts with dispatching, fire alarm, power supply and building automation systems. Undeveloped integration causes conflicts in control signals and failures in the operation of adjacent systems.
AYU-Project is working on the integration of the pumping station at the development stage DD:
- BMS (building management system) - transfer of telemetry about operating modes, pressure, flow and alarm signals to the facility’s unified dispatch system
- AFAS (automatic fire alarm) - for fire pumping stations: automatic start of working and standby pumps upon a signal from the fire alarm system with confirmation of the start
- SCADA - for industrial facilities: integration of ASU transformer substation pumping station into a common process control system via Modbus TCP or OPC UA protocols
- Power supply system - ATS (automatic switching on of a reserve) in case of loss of main power, priority of connection to a backup source for pumping stations of the first reliability category

Our Advantages
How We Work
Frequently Asked Questions
Yes, designer supervision is provided as a separate service. The design engineer visits the site within the agreed time frame, checks the installation’s compliance with the design solutions and records comments in the designer’s supervision log. This is especially important for stations of the first reliability category, where deviations from the design are unacceptable.
The placement of pumping stations in residential buildings is allowed if the requirements for noise and vibration levels according to SP 51.13330.2011 and GOST 51402-99 are met. AYU-Project designs vibration-isolating bases for units, flexible inserts on pipelines and, if necessary, sound-insulating enclosing structures of the turbine room.
Yes. For buried and semi-buried stations, AYU-Project designs a drainage system for the turbine hall with automatic start of the drainage pump from a flood sensor. Foundations for electric drives of pumps are located at a height of at least 0,5 m from the floor of the machine room.
For CPS, the following are required: estimated wastewater flow rates (maximum hourly and daily), characteristics and composition of wastewater, elevations of supply and pressure collectors, hydrogeological conditions of the site, requirements for the explosion protection class (for industrial facilities). If some of the data is missing, AYU-Project engineers will help you identify or request it.
The reliability category determines the permissible duration of interruption in water supply and requirements for redundancy of units. For stations of the first category, a break in supply is unacceptable - a backup unit and a backup source of power supply are required. An error in category definition will result in either excessive reservation costs or non-compliance with regulatory requirements.
Yes, reconstruction requires separate design documentation. In addition to the standard composition, the following are being developed: inspection of existing structures and equipment, dismantling work, solutions for retained equipment and its compatibility with new ones.
A packaged modular pumping station (PMPS) is factory-assembled in an insulated container with the equipment already installed. Its design package defines the factory configuration, container foundation, external pipeline connections and power supply. The documentation scope is smaller than for a permanent station, but site-specific adaptation remains mandatory.
Yes. AYU-Project develops both a complete set of design documentation and working documentation, as well as individual sections - technological solutions, automated process control systems, power supply. In this case, the initial data is an already developed part of the project of a third-party designer.
