Assessment of wastewater producing industries can take place by modelling the quantity and quality of discharged wastewater. We can do this by studying the production processes or by measuring (sampling and analysing) to get a representative answer. From these results advice is given about the possible reduction techniques of the wastewater components. Furthermore we advice about the necessary monitoring of the wastewater. We take the legal guidelines into account and know their contents and impact. To make the financing of environmental aspects possible a financial system can be developed. We are specialized in the planning, implementation and needed training for a financial system, like the wastewater levy system.
