In the initial period, as WALTHER Przedsiębiorstwo Przedstawicielsko-Handlowe Sp. z o. o., limited its activities to representing foreign companies in the fields related to sewage treatment plants with solid waste disposal and selection systems and with filtration techniques.

Since 1995, we have expanded our business to design, delivery and assembly, commissioning and development of expertise. At that time, we transformed into WALTHER Przedsiębiorstwo Innowacyjno-Wdrożeniowe Sp. z o. o. closely cooperating with research and development centers in Poland and abroad.

Close cooperation with the best global and domestic companies and universities has resulted in the creation of our own proprietary system of fine bubble aeration in sewage treatment plants.

In the field of liquid and gas filtration we have been and are a supplier of filtration systems for chemical and nitrogen plants, with particular emphasis on the filtration of gas mixtures.

In July 2012, we transformed into WALTHER URBAN Spółka Jawna as a continuator of history, achievements and all commitments since February 1991.
