Planning and reconstructing a sustainable water network for Szeged, Hungary

We developed a complete tool for sustainable network evaluation and reconstruction planning to help Szeged Water Utility improve its water supply system.

Szeged, Hungary has a large network of older pipes that are in dire need of replacement to avoid leakage problems. The pipes were constructed during the 1960s and 1970s and mainly made from asbestos cement. These pipes—which cover a wide network in the downtown areas—are more susceptible to failures and leakages than pipes made of steel or polyvinyl chloride (PVC). Due to wear and tear, a large number of them are now in a critical state and need to be replaced as soon as possible. 

In order to avoid serious leakages that could impede the entire water supply system, Szeged Water Utility needed to make immediate plans to improve the performance of their water supply network. Using MIKE CUSTOMISED by DHI, our team collected information about the city’s current network performance, which included pipe material and age, failure rates, leakage and other pipe properties.

Our tool allowed Szeged to create multiple network reconstruction scenarios while assessing the financial impact. This flexibility helped them identified the most critical pipelines as well as plan and reconstruct a sustainable water network. It also enabled Szeged to coordinate the network reconstruction plan with other investments in the area while working within the needs of network development.
