The Teleorman Flood Risk Management project was wrapped up on 28 May 2009, meaning that the renovation of the Botoroaga dam southwest of the Romanian capital of Bucharest is now done and dusted. TenCate Geosynthetics was involved in this undertaking and supplied TenCate Polyfelt® Polymat for erosion control.
Over the past years Romania – and particularly the Teleorman district – has been hit by floods caused by rivers bursting their banks, and in several villages buildings, infrastructure, cattle and land have suffered serious damage. In 2006 a consortium of partners was set up under the leadership of Royal Haskoning. The aim of this pilot project was to map out the risks of flooding and strengthen the Romanian water sector. As a member state of the European Union, Romania must comply with European rules and legislation. In terms of location, the much afflicted Calnistea basin caught the eye, and particularly the severely damaged Botoroaga dam.
The government wanted the project outcome to be more than merely plans and models. They looked for a partner for the dam renovation and found TenCate. The most appropriate solution would have been TenCate Geotube® but, owing to budget constraints, the consortium opted for geotextiles. Some 15,000 m² of TenCate Polymat was used in rebuilding the dam. Thanks to these geotextiles a durable construction has ultimately been achieved. The dam is so designed that once in every so many years it may be overtopped – hence TenCate Polymat, which together with the roots of the vegetation makes sure that the sand particles are not washed away.
