Wastewater treatment plant, Csepel, Hungary (Hungary)

The largest European Union wastewater treatment plant

Reference: Water 95% of wastewater treated />15% design cost reduction




Customer profile:

Today in Budapest, Hungary:

600 000 m3/day of wastewater is discharged into the Danube

46% of this water is not treated at all


Customer objective and constraints:

In 2002, Hungarian Program for Treatment of Waste Water specified that Budapest City has to comply in 2010 with the objectives of the 1994 Sophia Convention, which aimed at the protection of the Danube. The treated water has to comply with EU standards.


The two objectives of the city involve the construction of a plant capable of treating effluents generated by a population of 1,5 millions habitants. Veolia and Suez are leading the consortium designing this wastewater treatment plant with a capacity of 350000 m3/ day, the largest of the European Union. For this, the consortium needs a unique partner taking the full responsibility of the process and energy management solution completion: Schneider Electric.




Implementation methodology (main phases):

  • Complete study and design of the architecture.
  • Project management.
  • Standardization and objects library creation.
  • Full delivery and commissioning of motor control, process automation and energy efficiency from medium voltage to low voltage.

Solution overview (services, products, systems, architectures...):

How did we estimate the energy savings (methodology, tools, ...)

The global supervision of process, motor control and electrical distribution allows the reduction of energy costs. The results will be demonstrated after one year of operation.




Customer benefits:

  • Public authorities :

Compliance with European Union regulation

Energy efficiency

  • Design & Build companies :

Flexibility during design

Minimize the risk

95% of wastewater treated instead of 54%


Customer testimonies (Verbatim):

The upstream collaboration with Schneider Electric at the design stage allows standardisation and minimizes the risks all along the project.


Schneider Electric differentiating values VS competitors:

  • Schneider Electric is a global company well implanted in Hungary. Furthermore, Schneider Electric is a key and regular partner for Veolia and Suez
  • Schneider Electric has a Customer Interface. By fully managing the key steps of the project (provides a turnkey ED and Automation Scope for the project), Schneider Electric insures a single point of contact for the customer.
  • Deep technical involvement - not only limited to products but mainly focused on applications and projects
