We (SETEC Engineering) have developed a hydraulic calculation program called NESEI (NEtwork calculation SEtec International). The Program is working with AutoCAD, a database from GUPTA and with SURFER for the presentation of the hydraulic results. 

My masterpiece is the water supply system of Feldkirchen in Carintia Austria. You can see the different supply zones in different colors on the elevation model based on a grid 50 x 50 meters. The reservoirs, booster stations and wells are shown as symbols. We call up Surfer with ActiveX.
