OKO-tech wastewater treatment plants do not require much maintenance. As part of the obligations for self-monitoring under the Federal Water Act, we offer maintenance services once a year as a certified "specialist according to the Federal Water Act". In addition, we can provide additional services related to the operation of your wastewater treatment plant together with our national and international service partners. This can include the takeover of the entire operation of the wastewater treatment plant as part of an operator model. Thus, you can focus on your production processes and we ensure lasting optimum performance of the plant.
