Dutch companies working in water technology have been minimally affected by the impact of the corona pandemic. This is the overall picture presented in a trend analysis that was distilled from the results of frequent surveys of companies between April 2020 and January 2021. Although water technology companies only experienced a minor setback in revenue, the corona crisis has made them more cautious. For example, investments in research and development declined by 20 percent over the last year. In total, the investments in the sector declined by an average of 29 percent over the past 12 months.
