"Atyrau Su Arnasy" Public State Enterprise: Replacement of 90% of obsolete pumping equipment with Grundfos through leasing.



The site

Atyrau – the oil capital of the Republic of Kazakhstan, one of the fastest growing cities in the country.  

The history of Vodokanal in Atyrau, the state-run managing body for the city’s water facilities,   goes back to 1948, when Guryev Vodokanal was formed. Since its creation, Vodokanal has repeatedly changed its name and was reorganized many times. Public State Enterprise "Atyrau Su Arnasy" PSE was founded in 2006.

The source of water supply of Atyrau city is the Ural river. Water intake from the river is 18-20 mln. m3/year. Atyrau water supply and sewerage system serves more than 250 thousand of citizens and residents of Makat district suburban villages. The city has a centralized domestic and firefighting water system. The actual water supply is 70-75 thousand m3/day, the maximum one is up to 90 thousand m3/day. The volume of wastewater that are pumped with sewage pumping stations is 33 thousand m3/day in average.

"Atyrau Su Arnasy" PSE operates:

  • Complex of water treatment plants  
  • Water supply and sewerage networks with a total length of 1282.6 km
  • Water booster pumping stations, 45 units.
  • Sewage pumping stations, 89 units
  • Sewage treatment plant with capacity of 31 thousand m3/day.


The task

Before upgrading, approximately 20% of operating costs accounted for the payment of electricity.

Before the implementation of the program, in-depth analysis involving calculations and experience of Grundfos Company were carried out. For five years, the Grundfos specialists conducted the preparatory work. In 2008, 2009 and 2013, Grundfos conducted the free of charge Pump Audit for "Atyrau Su Arnasy" PSE. Grundfos in Central Asia offers Pump Audit with no cost for customer in order to support them in auditing of pumping equipment. Official dealers and service partners of Grundfos in Kazakhstan - "Research and Production Company Ergonomica" LLP and "Akvatoriya Aktobe" LLP - were involved in Pump Audit. Optimal solutions for the use of new pumping equipment were provided based on the comprehensive analysis.

Replacement of pumps and control cabinets with frequency converters at water treatment plants, replacement of pumps and control cabinets at sewage pumping stations has been planned based on Pump Audit. Replacement of the prefabricated pumping stations was planned on the water booster pumping stations.



The project was planned for several stages of the replacement of equipment in "Atyrau Su Arnasy" PSE. Special offer as leasing for three years was one of the bidding conditions. 191 units of pumps with 91 control cabinets were delivered in 2014 in accordance with the contracts between the "Atyrau Su Arnasy" PSE and "Research and Production Company Ergonomica" LLP in frame of the
first stage of program execution.  96 pumps with 42 control cabinets and 3 prefabricated sewage pumping stations "PUST" were delivered in frame of the second stage of program execution. This project in housing and communal services is a pilot project in Kazakhstan with an investment of private capital in state-owned enterprise.


Remote management 

Grundfos Remote Management (GRM) - data transmission system developed by Grundfos – was installed on the most remote booster pumping station of Atyrau as a part of the development of capacity of the Grundfos equipment. The system is a data transmission module with antenna and backup battery for the controller with the possibility of the pump station control within a GSM signal. The system allows sending the main parameters of the controller installed in the control cabinet to the central operator board, which makes it possible to track occurred errors and to react promptly, to monitor the power consumption of pumps, control of pumps operating hours, to change the set pressure in the pressure manifold automatically. GRM system configures and converts all the obtained data in the charts, allowing analysing and programming the work of the pumping station. In addition, the program displays the duty staff with the indication of name and phone number. In case of a pumping station failure the manager and duty staff
receive warning text via SMS message.


Energy Efficiency

Energy-efficient equipment saved electricity consumption up to 30%. Company’s energy saving were 5 million kWh for the period of 2014-2015. In general, the installed equipment allowed "Atyrau Su Arnasy" PSE to reduce energy costs, to improve the reliability of serviced systems, to reduce human resources for maintenance of facilities, to reduce operating costs.
