Bringing sewage back to life
24 Jul 2001
Haestad Methods has announced the release of SewerCAD v5, the latest version of their modelling software for sanitary sewer analysis and design.
SewerCAD has been updated to include hydrographic loading, extended period simulation, enhanced profiling views, and animation.
Due to strict regulations, cities with combined sanitary and storm sewer systems will benefit from the new extended period simulation feature, according to the company. The US EPA, for example, requires these municipalities to have no more than four overflow events per year, and to capture or eliminate at least 85 percent of sewage overflow.
The continuous time-based model will realistically simulate sewage-pumping operations and assist utilities in determining how much overflow will occur and where it will happen.
SewerCAD's new animation feature also brings the data to life. The animation and colour-coding capabilities in plan and profile views highlight the system's simulated reaction to various conditions, including overflow trouble spots.
'SewerCAD graphically expresses the dynamic behaviour of the sewer system, demonstrating its reactions to the stresses that are placed upon it,' says Gregg Herrin, a Haestad Methods Civil Engineer and key SewerCAD designer. 'Animation in particular helps bring insight to the seeming chaos of a sewer network.'
SewerCAD's profiling tool has also been improved, offering the user greater flexibility as well as manageability. New profile templates can be tailored to include common styles and settings for use in generating construction drawings.
