Efficient Use of Gas. Natural gas as an alternative fuel can help to reduce CO2 and other transport-related pollutant emissions quickly and cost-effectively. The DVGW is a recognized standardization body for the gas and water industry, a centre for technical and scientific know-how in the gas and water sectors and an initiator and promoter of research projects and innovations.
News 19 December, International Experts work on Concept for Greening of Gas How natural gas and renewable gases can accelerate the global reduction of fossile fuels emissions. On the other hand, the evaluation of the findings according to Table 1a of the W is very relevant to practice.
Safety and Security Technical Safety Gas. The possibility given by the Federal Environment Agency to omit individual climbing strata if the selected selection of risers permits a reliable statement about the untested eg because they are similar, have the same building parts, are equally used or are hydraulically unfavorable Is, for example, unworkable and involves liability risks in the event of damage.
The growing amount of data and ever more complex tasks lead to more stringent requirements being made on IT security in the gas and water industry.
The DVGW is the central point of contact for all actors in the gas and water sectors. In order to determine a possible contamination of the system with legionella, a preliminary examination is first to be carried out.
It is advisable to take additional samples from individual sampling lines which provide evidence of possible contamination to the sampling points according to the orientation test on each strand.
Only by sampling all the climbing strings is a differentiated picture of the contamination happening in the entire pipeline system. This is because the binding specification can only be made by hygienically competent personnel, must also be retained for future sampling risk of confusion and is neither clearly defined by the wording nor by the system of W The technical regulations applicable to the implementation of the Legionella test are the DVGW W “Drinking water heating and drinking water pipelines, technical measures for the reduction of legionella growth, planning, construction, operation and rehabilitation of drinking water installations”.
The sample volume thus goes well beyond that of the investigative study. Samples must be taken according to the acknowledged rules of technology.

If a legionella concentration above the technical measure of KbE is determined during the orientative examination, the W recommends a further investigation to obtain a statement about the exact extent of the contamination of the system with legionella and to allow the initiation of targeted restoration measures. In addition, a sample must be taken at the outlet of the DHW cylinder hot water pipe and a sample at the inlet to the DHW cylinder circulation pipe.
