Water Supply Rehabilitation Ózd

Progetto concluso
Antiquated pipeline
Most of the water supply infrastructure in Hungary is 50 to 60 years old and is in poor condition because of the inferior quality of the pipes. Most of the pipes are made of asbestos cement and cast iron. © SECO

The control system for the water supply in the municipality of Ózd is antiquated. A district with 700 to 800 households are not connected to the central water supply network. Switzerland intends to change this situation by a project contribution of CHF 7.1 million. The aim is to ensure the same level of service standard in the entire municipality, to improve the water quality, and to reduce maintenance costs.

Note: the texts under all the headings, with the exception of 'Results achieved', describe the situation before the start of the project.


The municipality of Ózd town in partnership with the Ózd Water and Canalisation Ltd, a publicly owned company that operates the drinking water supply, strives to rehabilitate the most critical elements of its water supply infrastructure (network pipes and devices and storage basins). The transportation mains, city mains and household connections suffer from early aging due to poor quality of the pipes, un-thorough execution of the mounting works and insufficient bedding of the pipes. Furthermore the deterioration is accelerated by the aggressive geological conditions.
