Innovative solutions
Successful consulting is competent and cooperative. The optimum and innovative solutions we devise for our customers are based on this principle. Our work encompasses the entire water cycle. Founded in current research results, technical rules and practical experience, our flexible and highly qualified teams deliver comprehensive, future-oriented responses to our customers’ challenges. As a non-profit and independent institution, we focus on technical and economically sustainable solutions.
Water analysis
Here you will find our range of services on physical-chemical and microbiological water testing in accordance with the German Drinking Water Ordinance, individually tailored monitoring programmes and other statutory requirements as well as information on the latest micropollutants analytics using our cutting-edge analysis equipment in our accredited laboratories.
Testing of materials and products
Our Test Centre is accredited for more than 200 different product standards according to DIN EN ISO 17025 and offers preliminary testing of materials and products that come into contact with drinking water. Corrosion can cause damage to water supply systems. We have in-depth specialist knowledge on this topic and can conduct damage analysis on your behalf.
Treatment technologies
For our customers’ drinking water supply we develop structural concepts for the future and implement new technologies. We also advise you on monitoring existing treatment processes and optimising them in line with the latest research findings.
Micropollutants and microorganisms
Trace analytical methods are becoming increasingly important. We develop and improve the determination procedures using high resolution equipment. Combined with lab and field trials, this enables us to investigate the presence, behaviour and retention of inorganic and organic micropollutants in the water cycle and in drinking water treatment.
Network management and drinking water installation
Our experts provide advice on the topics of microbiological quality changes, corrosion-induced deposit formation, and cleaning and optimising the operation of distribution networks. We provide you with the scientific and technical support you require when carrying out rehabilitation work in drinking water installations.
Drinking water catchments and resources
Recording and evaluating potential hazards in water catchment areas enables us to create specifically adapted catalogues of measures for groundwater and water protection. Long-term monitoring programmes and the operation of supra-regional databases on groundwater and raw water quality also contribute to the safety of drinking water supplies.
Risk management
Water suppliers are obligated, according to the Drinking Water Ordinance, to implement a risk management system for their entire supply system, from the abstraction point to the consumer. We provide support in the establishment and implementation of such a management system, drawing on our extensive experience from numerous national and international research projects as well as commissioned tasks.
Contaminated sites
Soils and groundwater can be affected by contaminated sites. We evaluate the decomposition potential at contaminated locations. Natural biological degradation processes in the underground provide a cost-effective, environmentally friendly and sustainable way of eliminating pollutants from the environment. Our customised concepts combine both microbiological and technical procedures.
Digitalisation
In all areas of drinking water supply digitalisation plays a decisive role today. With our digital know-how, we can provide competent support here. This includes process analysis and optimisation, the processing and evaluation of high-dimensional data using both deterministic and machine learning models, technical-scientific expertise regarding data architectures and databases as well as the development of web applications and software.
Practical projects
Both sides benefit from projects with partners from practice: Research at TZW, because it is practical and relevant, and water suppliers, because they can experience the latest developments at first hand and help shape them. To provide an overview of what such partnerships look like, a few selected examples of successful projects with practice partners are presented here.
