EWEES is being produced in collaboration with many research teams in Europe (U.K., Greece, the Netherlands, Ireland, Italy).EWEES is meant to help avoid farm pollution by better decision making. The expert system is designed to act as a human expert would do, by logical reasoning process to approach the problem solving in a broad way. Steps are followed in the research of solutions by the system. First, the user gives the main constraints and requirement to characterize the problem; secondly a system of rules are applied in order to find the technical approaches that are more likely to solve the problem. Several alternatives can be presented and explained to the user and recommendations are made considering the input information given. The 3rd step is when needed detailed engineering solutions and finally the user can calculate and compare the costs of the proposed solutions. Technical, managerial, economic and legislative information are integrated to the expert system.

This system is intended to help the human experts in the field in their analysis of different situations. Human touches are always needed for unusual problems and also in analyzing the options presented in keeping the broad perspective of each specific situation. The precision of the elements and information put in this expert system have a direct impact on the exactitude of the results.
