35 years of medical technology from Ubstadt-Weiher

A company anniversary is always an occasion for joy, an opportunity to take a look into the past, to reflect the present and to look into the future with visions.

Ultrapure water is a fundamental element for dialysis, i.e. artificial blood washing, in patients with severe kidney disease. A highly complex technology is required to obtain truly pure water as dialysis water (permeate) and transport it to the dialysis machine. This technology has been further developed by DWA in Ubstadt-Weiher for 35 years and implemented in modern water treatment systems.

At the beginning of our company history, Mr. Karl Walther had the idea to develop his own business in the field of dialysis water treatment. His vision was preceded by almost 20 years of personal experience as a nurse, as head of a dialysis station, as a service technician in medical technology and as a salesman for a well-known filter manufacturer in the USA. With this bundled experience, the company was founded on February 22, 1984 by Karl Walther with six employees and successfully expanded nationally and internationally until 1995.

Since 2009 DWA belongs to the Belgian Pollet Water Group. In addition to solutions for the home, industry and gastronomy, water treatment for medical applications, including dialysis, is one of the main business areas of the group. Founded in 1992, the group today comprises more than 30 companies in the field of water technology in eleven countries worldwide.

As an independent company, DWA currently employs 60 people, three of them almost from the very beginning. All together we are almost 1,000 years old in experience and are still aware of our responsibility as specialists in the field of ultrapure water supply for dialysis. Since 2005, we have firmly implemented dual training in the company to promote young talent.
Constant growth at home and abroad as well as ever more extensive customer projects made it necessary to move to the Großer Sand industrial estate in Ubstadt-Weiher in a larger company building at the end of 2015.

Development, design, production, commissioning, service and maintenance all come from a single source. As a full-service provider, we are ideally positioned for all issues relating to water treatment for dialysis. DWA is a strong partner not only in many centres in the surrounding area such as Bruchsal, Speyer, Schwetzingen, Hockenheim (...), but also in countries such as China, Saudi Arabia, Canada, Kenya, Australia and throughout Europe.

Managing Director Bernd Gegenhuber and his team look to the future with confidence. With the balance of the past year, a more than satisfactory result was once again achieved. DWA will present some novelties on the market in the next months. Among other things, the digital hospital will be considered, but more about this is not yet revealed.

The 35th anniversary will be celebrated with the staff on a small scale and the value of an anniversary celebration will be donated to two social projects in our community.
