ARTS covers steady pipe flow of water, air and sludge in single pipes and pressure networks, gradually and rapidly varied flow in open channels, waterhammer in rising mains, wastewater teatment units and systems design.

The ARTS graphical interface is intuitive and easy-to-use. It enables users to use sketch diagrams to define systems and convey information. Designers are given access to powerful analyical tools, while at the same time retaining a well-proven traditional approach to system definition.
