Pumps & valves Camargue flood prevention with KSB In 2013 a €9M environmental engineering programme involving more than doubling the total capacity of seven pumping stations in the Petit Camargue, France, was completed. The flood prevention strategy, which had started back in 2003, involved the pump engineering and construction resources of KSB <=> less is more Wassergewinnung Talsperre Aufbereitung Talsperre Aufbereitung Wassergewinnung Wassergewinnung Talsperre Talsperre Aufbereitung Speicher Pumpwerk Rohrnetze Wassergewinnung Talsperre Aufbereitung Speicher Pumpwerk Rohrnetze Wassergewinnung Talsperre Aufbereitung Speicher Pumpwerk Aufbereitung An easy to navigate website means quicker information Speicher Industrie Rückgewinnung Rohrnetze Bewässerung Industrie Pumpwerk Rohrnetze Bewässerung Industrie Rückgewinnung Pumpwerk Rohrnetze Bewässerung Industrie We have cleaned up our website making it easier Kraftwerk Klärwerk Gas Rückgewinnung for you to find the information you want.

Covering an area of 55,000ha, of which 38,000ha comprise wetlands, the Petite Camargue is largely given over to agriculture and fisheries, whilst its very special flora and fauna make it a haven for wildlife and tourism. With large areas of the Petite Camargue lying some 2m below sea level, it is prone to regular flooding resulting from the rising levels of the rivers Vistre, Vidourle and Rhȏne, and sometimes by breaks in the dykes. The earth of the wetlands is naturally saturated so in the event of great floods, when water courses rise above river and drainage channel banks, some 300km² of the Petite Camargue can be transformed into a massive overflow area. This means that the water gathers here until it flows or drains off again, a process that can take time and at a considerable cost to the local communities. Pumping stations have eased the burden, with the flood water being initially pumped from the flooded areas and then fed into the Rhȏne where it flows into the sea. However, in the past 20 years these stations have proved to be inadequate when put to the ultimate test. Intense flooding occurred in 1993 and 1994 and, as a result, a special body − Syndicat Mixte de la Camargue Gardoise (SMCG) − was established with the eight communities affected to address the problem. Eventually in 1998 a further public body was created to investigate how to reduce the risks of flooding, with the results expected by 2003. However, in September 2002, flooding of the Rhȏne upstream occurred and this had a serious affect on the region. This was followed in December 2003 when flooding on the Rhône and its main tributaries took on considerable dimensions. In the lower course of the Rhône, which runs in part along the Petite Camargue, 2003 was the third-largest known flood. In Beaucaire, which is situated several kilometres north of the Petite Camargue, floods peaked at 11,500m³/s. In the lower course of the Rhône it took several days and weeks, before the water flowed into the sea. Some residential areas were 4m underwater and 32,000 people had to be evacuated. The floods covered 30,000ha, caused damage worth an estimated €300M and took more than three months to pump clear. 'Camargue Gaudoise' was initiated in 2005 which, although not being able to completely prevent flooding, would limit damage to land and property. The main objective of the project was to shorten the time in which the area from Saint-Gilles to Le Grau du engineering work being undertaken at Sylvéréal
