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.

Head of Service & Development
Our specialists will be happy to assist you with their know-how in the areas of water and wastewater treatment. As part of our consulting services, we can carry out preliminary evaluations, design option studies, and feasibility studies. In the case of existing plants, we can carry out surveys and status analyses on request, with a view to optimizing operation or identifying viable options for the future.
Every project starts with proper identification of the water quality and the quantity of water to be treated. For this reason, we frequently offer field measurements so that these parameters can be determined reliably to put the project on a solid footing. Our in-house laboratory allows us to carry out chemical analyses on behalf of our customers right away. Another key focus of our professionally run lab is filter media analysis, which is not only very important for us as an independent supplier of filter media but also for our customers as users.
Plant engineering is our passion – we call it “passioneering”.
We have been providing Swiss drinking and wastewater treatment plants with the finest technology for more than 60 years. As the largest supplier of water treatment plants in Switzerland, our determination to deliver the highest possible technical quality and reliability stretches back decades.
Our core business is planning, procuring, delivering, installing, and commissioning water treatment plants, and then handing them over to our customers as turnkey solutions.
In addition, we regularly build and run pilot plants for the purpose of investigating which treatment technology is the right one to use. Pilot projects are usually undertaken in close collaboration with the customer and any relevant institutes.
The fact that we have been rooted in Switzerland for so many years makes us a special partner with whom customers can enjoy a long-term and dependable business relationship. Once a plant has been built, we continue to provide our customers with support in the areas of surveillance, plant management and operation optimization according to their needs. And we are also happy to help them with any future expansions or renovations.
Our design team produces plans in 2D as well as in 3D. In addition to classic plant design, we can also offer building scanning and plan digitization services.
We do not just follow the latest trends – we like to set our own. That is why we are constantly striving to apply the practical experience we have acquired through our installations by making specific improvements to the process technology. Take, for example, the various key components and treatment technologies that we have managed to develop and patent over recent years: WABAG Decanter, WABAG FLUOPUR, WABAG Filtration, etc.
