The LoadBuilder module included in SewerCAD helps you allocate sewer loads based on a variety of GIS-based sources such as consumer water use billing data, area-wide flow measurement, or polygons with known population or land use. Sewer loading in SewerCAD also can be applied as user-defined hydrographs, pattern-based loads, and unit loads. You can use customizable unit load libraries to estimate sanitary flows based on contributing population, service area, total dry weather discharge, or your own customized loading types. Loads can be allocated individually to property connection elements, or collect to manholes and other node elements.
SewerCAD also includes numerous pre-defined extreme flow factor formulas and tables, including Babbit, Harmon, Ten State, and Federov’s – or lets you enter your own formulas and tables. SewerCAD determines infiltration in gravity pipes, based on pipe length, length diameter, surface area, count value, or user-defined data. SewerCAD can also use multiple flow patterns or flow hydrographs for EPS. The sanitary load control center and inflow control center make it easy to globally edit or edit a filtered set of elements.
