Berlin Water Night
Just the right event for Berlin
WASSER BERLIN INTERNATIONAL is just the right event for Berlin, a city where 6.6 per cent of the surface area is covered in water. For that reason, and because of favourable groundwater conditions, Berlin is 90 per cent self-sufficient where fresh water is concerned. This was noted by Senator for Economics Ramona Pop at the Berlin Water Night which took place on Tuesday evening. Furthermore, there was a concentration of water expertise in the city, including at the ‘Kompetenzzentrum Wasser’ and the research institutions at Berlin’s Technical University, she added. Industry and businesses were widely represented here too. Jörg Simon, CEO of Berlinwasser, described his company as providing a strong basis for combining practical topics with commerce and production, for which the fair offered an outstanding forum. A baroque-inspired firework display accompanied by the music of ‘Berliner Luft’ and featuring the classical elements of earth and water rounded off the evening event.
Iran requires large investment to ensure water supplies
Iran is one of the world’s regions lacking access to water, for which there is no immediate solution. At the Iran Conference at WASSER BERLIN INTERNATIONAL Iran’s Deputy Energy Minister Rahim Meidani said that climate change was responsible, as average temperatures had now risen. At the same time annual precipitation had declined, although there was a rise in heavy rainfall from individual weather events. That was why Iran had set up a number of water infrastructure projects. Meidani invited German investors to participate. He said the state would offer guarantees, but also mentioned that joint ventures would have to be established in which Iranian companies held a 51 per cent majority. Referring to a specific project in which his company was involved, Ludwig Pfeiffer, a construction company owner, rejected this statement because there were no relevant businesses in Iran. Representing the loan insurance company Euler Hermes, Sebastian Boseke pointed out that Germany’s federal government offered special guarantees for foreigners investing in Iran. During the public debate however, it was noted that the risk of sanctions being re-introduced against Iran still hampered long-term investment.
Insufficient access to water is why a sustainable water cycle is needed
Four billion people live in regions which already suffer from a lack of water or where that threat exists. Speaking at the Congress Forum at WASSER BERLIN INTERNATIONAL Ger Bergkamp, managing director of the International Water Association (IWA), said this was why it was so important to uphold internationally agreed targets for a sustainable economy, especially where water management was concerned. He also cautioned that were big challenges ahead, in the administrative field, for example. The transition from consumer-based to sustainable economy had to be undertaken by taking consumer needs closely into account, he said, otherwise it would fail. As far as cities were concerned, he recommended a less centralistic approach, and instead a more ’water-oriented’ concept that could face up to the challenges ahead. Against the backdrop of different cultures in the relevant regions it was necessary to decide on what was feasible and what was not before entering into any talks, he said.
Flood Management Symposium
Local councils have a responsibility for managing rainwater
There is still much to be done where managing rainwater is concerned, particular in the case of flash floods. These were the words of Professor Wolfgang Günthert of the Munich Bundeswehr University as he addressed local councils at the Experts Forum on the subject of flood management at WASSER BERLIN INTERNATIONAL. Because of climate change sudden and heavy rainfall could now occur much more frequently and without warning, he said. Furthermore, as these events were local they were also very hard to predict. Local councils’ plans were often based on scenarios that included neither these events nor the fact that housing increasingly paved over open areas. For financial reasons it was not possible to ensure that local sewage systems were able to fully cope with water from flash floods. However, it was not the responsibility of local councils to finance precautionary measures on private property, although they had to inform the owners of the risks. In many cases such measures were neglected for cost-saving reasons. An evaluation of this kind was “about the same price as a car”, Günthert said. Without such an evaluation the damage from heavy rainfall easily exceeded the cost of a car, he added.
NO DIG BERLIN
The particular challenges facing pipeline construction
Over the next ten to fifteen years the expansion of high voltage systems will present particular challenges for pipeline construction in Germany. This view was stated by Dr. Marc Peters, Head of the Energy Division of Herrenknecht AG, in the paper entitled ‘New trenchless technology for small diameters and long drives and its use in underground cable installation’ at NO DIG BERLIN. Due to the various different types of obstacles such as roads and railway tracks, this work has to be carried out using a trenchless method over distances of between 150 and 250 kilometres, explained Dr. Peters. Moreover the technology involved has to comply with the specific requirements of the network operators. Methods in use in the water industry cannot be deployed in the same way in the energy sector, the speaker pointed out. It is for this reason that Herrenknecht has developed a new, two-stage process for the trenchless laying of underground cables, the AVNS 350 XB automated slurry-supported tunnelling machine. Together with the newly developed pilot pipes it enables the target time of 12 to 15 days for laying the cables to be met, Dr. Peters explains.
German Toilet Organization e.V.
Pupils drink symbolically hazardous wastewater
On Thursday (30 March, 10:45 a.m.) pupils from four Berlin schools will symbolically drink a hazardous wastewater cocktail at the public exhibition WASsERLEBEN, part of WASSER BERLIN INTERNATIONAL. This will be taking place during a press conference by the German Toilet Organization e.V. to draw attention to the fact that many people, especially in southern latitudes, still do not have hygienic access to drinking water. As a result millions of deaths occur annually, and children are particularly vulnerable because their bodies' defence systems are not fully developed. The campaign ‘Brown water stinks’ is part of a programme aimed at speeding up the introduction of sustainable wastewater disposal and treatment.
Exercise by the KKI crisis team
Close-up look at crisis management
Following the keen public interest aroused by the crisis team's exercise two years ago at the fair, this interactive forum is being staged again by KKI – Kompetenzzentrum Kritische Infrastrukturen GmbH in cooperation with Messe Berlin, reports Heiko Hausrath, assistant to the KKI management. As he explains, following the publication of the book ‘Blackout’, companies are displaying a greater awareness of the subjects of crises and crisis management. This has led to increased efforts to prepare adequately for such extreme hazards as flooding, extreme weather conditions, and power or IT failures. The KKI crisis team exercise describes a particular scenario and acts out the required management over the course of an hour, in accordance with the principle: emergencies and crises can be overcome by adopting a systematic plan. "We endeavour to explain the subject of crisis management, and to make it understandable in an entertaining way," explains Hausrath.
Aerzener Maschinenfabrik GmbH
Making energy saving simpler
From an economic perspective the deployment of heat recovery systems through the use of process heat is looking increasingly attractive. AERZEN can offer innovative concepts for achieving lasting reductions in the energy used. This exhibitor reports that savings of up to 90 per cent can be achieved with the minimum of effort. Process air can be produced in an energy-efficient and economical way, although plant operators rarely recognise this potential for making savings. With relatively low investment costs the expenditure on installations or integration in a company's operational processes can pay for itself in just a few months. AERZEN is a specialist in such applications and can offer heat exchangers designed with great accuracy to provide the maximum transferable heat and the minimum loss of pressure. Older compressed air installations can also be improved and retrofitted to make them more energy-efficient.
Anticimex sewer traps
The SMART-Trap from Anticimex is an intelligent system for dealing with rodents in wastewater systems. The sewer trap does not use poison, is eco-friendly and is fully automatic. Sensors register body heat and movement in the sewer pipe and activate the trap when a rat passes it. Hydraulically propelled bolts strike the animal at a speed of 130 kph, killing it instantly. It is then flushed away and the trap is ready for action again in one and a half minutes. The company reports that these traps set a new standard and guarantee around-the-clock protection and monitoring. The reduction in the rodent population within the area being monitored can also be detected from above ground.
System for real time monitoring, information and early warning in tunnel construction
The ribeka company specialises in developing software solutions for the water industry, primarily in the areas of ground and surface water management, as well as solutions for managing environmental data and water resources, and it also provides GIS and database solutions. With the ‘Albabstieg Tunnel’ project, – Drainage, part of the DB Stuttgart-Ulm tunnel construction project, this exhibitor is using ‘Base 9 / GW-Web’ for a web-based, real time monitoring, information and early warning system in accordance with the Water 4.0 concepts. The continuous groundwater readings are integrated directly online in geological and technical profile sections. In this way they are constantly available to the site management and employers to ensure safe progress of the work and drainage during the tunnelling operations. With agreed access rights the system provides comprehensive functions for control purposes, preservation of evidence and report management.
