I use 3 types of hydraulic modelling software in my work. Aquis, MIKE+ and KYpipe.
Aquis is my primary software for danish clients for real time modelling and network planning, MIKE+ for norwegian and swedish clients and KYpipe i use for transient modelling, allthough it can also be used for hydraulic modelling.
EPANET is a part of MIKE+ and i dont really use the standard EPANET software other then converting Aquis models to MIKE+, where the EPANET software is a step on the way.
Bentley and Innovyze also provides hydraulic software, but i dont have any experience in them.
