As a result of the continuous development of the catchment area and increased demands on water pollution control, the Kloten Opfikon WWTP, designed in 1993 for 54,500 PE, is expanded to a capacity of 125,000 PE. This is being done without requiring additional space, made possible with the use of the extremely compact NEREDA® process, which operates with aerobic granular biomass. In summer 2021, the first of 4 NEREDA® reactors was successfully commissioned, followed by two further stages of conversion and expansion starting in December 2021, which will be completed in 2024.
«With its many years of experience and wide array of processes, WABAG Wassertechnik AG can offer systems and plants that are perfectly tailored to customer needs. What's more, we develop innovative solutions and bring new process technologies – such as our Nereda process – onto the market.»
WABAG Water Technology Ltd in Winterthur is the largest supplier of drinking water and wastewater treatment plants in Switzerland.
The Winterthur site employs more than 40 members of staff in Sales, Engineering, Project Management, and R&D. Our services include planning, design, execution, commissioning, and customer service – for everything from system components through to complete turnkey plants.
We have long devoted ourselves to the construction of water treatment plants and in that time have developed many processes ourselves. In light of this, we have built up a diverse portfolio of references. However, our extensive research and development work is just as important as our experience because this is what allows us to provide advanced and economical solutions for the tasks of the future as well as those of today.
WABAG is one of the world's most innovative companies in the field of water and wastewater treatment plants. It has a wealth of experience and offers many processes that have been developed in house.
Within the WABAG Group, WABAG Switzerland is the technological competence center for drinking water (ultrafiltration, multi-barrier systems), biofiltration (BIOPUR®), and moving bed technology (FLUOPUR®).

With WABAG, you can count on custom solutions that are geared toward the future thanks to its more than 100 patents.
Our wealth of experience in planning, constructing, and managing water technology plants enables us to provide customers with complete solutions that perfectly meet their needs. By combining construction with plant management (such as DBO, BOOT) as part of project execution, we believe we can lay further foundations for making the WABAG Group even more successful.
Since 1995, we have installed more than 1,400 plants worldwide. As a result, our plants are providing over 200 million people and more than 500 industrial firms with clean water.
