During the 20 years, Ehting Company has developed and successfully applied "Methodology for reducing a water looses in water supplying systems". Early 90's, Ehting Company gained from Business Alliance of Water Supply and Sewerage of Yugoslavia, PLEDGE - Recommendation of Quality for the above methodology.

This was the beginning of the developing the methodology. Today, the operational and the full implementation of information system which is based on a unique database that communicates with four segments of information systems: the processing of water consumption, mathematical modeling, GIS and SCADA. This is the basis for program implementation of methodology.
 Ehting is representative of the company, "PROTOK" doo from Zagreb to Serbia for
ProGIS software package, used for Information Systems in the communal infrastucures.
