Floods in poland 2010: tHw high-capacity-pumps lower<br />

water levels<br />

Essay by Christian Goihl, Project Manager ETS, Unit E 2, Federal Agency for Technical Relief (THW), Germany<br />

In May and June, large areas of Poland<br />

were flooded for weeks on end and the<br />

floodwaters threatened to cross the border<br />

into Germany. During the first and the<br />

second wave of the floods the German<br />

areas were not strongly affected, but the<br />

Polish villages were heavily hit. So, the<br />

EU, Germany and also then the THW were<br />

asked twice to support the Polish rescue<br />

units in its struggle to contain the floods<br />

with its High Capacity Pumping Modules<br />

(HCP). In both operations over 1.5 billion<br />

litres of water were pumped away with<br />

a total of 300 THW volunteers in action<br />

during the whole mission period in Poland.<br />

Sandbags enforce the banks to stop the<br />

water<br />

Heavy rain in May led to many rivers<br />

bursting their banks in Poland, the Czech<br />

Republic, Hungary, Slovakia and Serbia.<br />

The situation in the other countries quickly<br />

returned to normal, but in Poland it took on<br />

disastrous proportions. Southern regions<br />

of the country disappeared under water<br />

and thousands of people had to leave their<br />

homes. In the middle of May a dam burst in<br />

Kraków as the River Vistula swelled to its<br />

highest level since 40 years. In response,<br />

on May 19 the Polish government requested<br />

assistance via the EU’s Monitoring and<br />

Information Centre (MIC) in Brussels.<br />

In accordance with the EU Community<br />

Mechanism, assistance for the Polish fire<br />

department in its struggle against the floods<br />

was provided by deploying HCP modules<br />

to the crisis area from France (four), the<br />

Baltic states (one) and Germany (five).<br />

The five HCP modules use an extra-highcapacity<br />

channel impeller pump known to its<br />

users as the “calamity pump” because of its<br />

high flow rate of 15,000 litres per minute, as<br />

well as two other high-capacity pumps with<br />

flow rates of 5,000 l/min. These heavy-duty<br />

pumps allowed 200 THW volunteers (incl.<br />

replacement teams), present in the first<br />

mission phase, to drain streets, industrial<br />

plant, pumping stations and entire housing<br />

estates. After days of pumping, the water<br />

levels finally began to recede and the<br />

situation eased off somewhat. One after<br />

the other, the German HCP modules were<br />

able to end their intervention in the flooded<br />

areas during the first week of June.<br />

The water returns<br />

However, the returning units had only just<br />

begun to hang up their boots to dry when<br />

the call came to deploy further units for<br />

another mission to Poland. Fresh rainfall<br />

in mid-June once again led to river levels<br />

rising and, particularly in the southeastern<br />

parts of Poland, the dykes could<br />

no longer hold back the water. Within a few<br />

days, recently drained areas were flooded<br />

anew. Sandomierz and Tarnobrzeg were<br />

particularly badly affected so the Polish<br />

government again requested assistance.<br />

They were already back in action on June<br />

14th, operating around the clock. At peak<br />

capacity they were pumping a total of<br />

110.000 litres of water per minute back<br />

over the dykes.<br />

700 million litres in nine days<br />

The town of Tarnobrzeg was one of the<br />

areas that suffered the most. Eight weeks<br />

after the first dams burst, the floodwater<br />

in the Wielowies district was still several<br />

metres deep, covering an area of five square<br />

kilometres. This part of the town lies in a<br />

depression. The water could not flow back<br />

into the Vistula river, transforming the area<br />

into an artificial lake. THW volunteers from<br />

the regional offices Hamburg / Mecklenburg<br />

- Western Pomerania /Schleswig-Holstein/<br />

Bremen and Lower Saxony were here in<br />

action for nine days, pumping more than<br />

700 million litres of water out of this one<br />

housing estate alone. In Sandomierz, THW<br />

volunteers from North Rhine-Westphalia<br />

pumped water from a housing estate into a<br />

harbour basin more than 300 metres away.<br />

Before they could start, however, to lay their<br />

hoses under the surface, they had to open<br />

the surface of a heavily used road with the<br />

support of a local building company.<br />

Meanwhile, in Janowiec, a HCP module<br />

was draining water away from the local<br />

pumping station. Because of the floods,<br />

an ordinarily small stream was unable to<br />

flow into the Vistula river, flooding a large<br />

part of the 1,000-inhabitant town, including<br />

its local pumping station. One extra-highcapacity<br />

pump and two high-capacity<br />

pumps were in action, with a combined<br />

flow rate of some 20,000 litres per minute<br />

helping to lower the water level for more<br />

than one metre. Afterwards submersible<br />

pumps were used to remove the remaining<br />

water from the pumping station. Water<br />

was also pumped back over the dykes in<br />

Las Debowy, near Opole Lubowski. The<br />

THW-experts, who operated in this area,<br />

came from Hesse/Rhineland-Palatinate/<br />

Saarland.<br />

Water levels finally dropped<br />

After two weeks the flood waters were<br />

retreating at last in the affected areas<br />

of Poland. Isolated ‘lakes’ remained but<br />

the water no longer covered large areas.<br />

5<br />

THW volunteers were able to finish their<br />

missions as the local authorities took over<br />

the remaining “pumping and clearing up” -<br />

tasks.<br />

In total, this THW mission in Poland<br />

amounted to several thousand working<br />

hours and pumped more than 1.5 billion<br />

litres of water. It ended on June 30th, 2010.<br />

In June 2010 the THW pumped down more<br />

than one billion litre of water<br />

“Emergency Temporary Shelter-Modules”project<br />

at in the headquarters of the German<br />

Federal Agency for Technical Relief (THW)<br />

in Bonn, Germany. Additionally, he has been<br />

working as volunteer with THW and Malteser<br />

Emergency Service in Cologne in the area of<br />

Civil Protection and Rescue Services. Due to<br />

his work at Siemens IT Solutions and Services<br />

in Paderborn and Munich he gained experiences<br />

in Business Continuity Management as<br />

well as in <strong>Disaster</strong> & Risk Prevention. He studied<br />

Rescue Engineering at the University of<br />

Applied Sciences in Cologne. His thesis dealt<br />

with the High-Capacity-Pumping-Modules of<br />

Germany and Czech Republic within the EU<br />

Community Mechanism for Civil Protection.<br />

The Federal Agency for Technical Relief THW<br />

was founded on August 22 nd , 1950 by Otto<br />

Lummitzsch on behalf of the German Federal<br />

Ministry of the Interior. 60 years later, the<br />

THW has approx. 80.000 members, including<br />

approx. 42.000 active volunteers, approx.<br />

15.000 youth, approx. 8.000 girls and women<br />

and about 800 employees.<br />

With its 1.000 Technical Units and 1.440 Rescue<br />

Groups, incorporated into 730 Technical<br />

Platoons, THW gives assistance on request of<br />

the local authorities within Germany and abroad<br />

on behalf of the Federal Government of<br />
