Introduction
ARTS is an hydraulic analysis/design software package, developed to meet the analytical needs of water and wastewater engineers. It gives easy access to a comprehensive range of hydraulic solutions through a specially developed graphical interface. A great amount of time, effort and expertise has been put into the development of the ARTS interface. The outcome is an intuitive, easy-to-use interface which enables users to follow the well-established engineering design practice of using sketch diagrams to define systems and convey information. Thus, designers are given access to powerful analytical tools, while at the same time retaining a well-proven traditional approach to system definition. In addition to its comprehensive analytical capability, ARTS comes with unique hydraulic design features, that guide the designer through the design process in a step-by-step procedure. This greatly reduces design time, while at the same time guiding the designer towards an optimum solution. In addition to its analysis/design functionality, ARTS comes with a full range record-keeping and report-producing features, that enhance its value in a design office environment.
