  2. Developing and applying monitoring and control schemes to adequately manage the health and quality risks associated with reuse of treated wastewater and recovered resources.
  3. Optimization of the value chains to quantify the improved resource efficiency and economic benefits, also with respect to future applications.
  4. Introduction of new legal categories of “reclaimed water” and “water reuse” into the Czech water law.
