What is SewerCAD?
SewerCAD is an easy-to-use sanitary sewer modeling and design software that thousands of municipalities, utilities, and engineering firms around the world trust to design, analyze, and plan wastewater collection systems. With SewerCAD, you can model both pressurized force mains and gravity hydraulics with ease, using steady-state analysis with various standard peaking factors, and extended-period simulations.
Out of the box, you can employ this product as a stand-alone application or work directly from within MicroStation, while an addition integration option lets them model within AutoCAD. Regardless of the platform used, SewerCAD maintains a single set of modeling files for true interoperability across platforms.
The stand-alone interface offers easy-to-use model layout tools, multiple background support including Bing aerial imagery, conversion utilities from CAD, GIS, and databases, and the use of terrain models to dynamically update node ground elevations, display surface contours and profiles, and design conduit inverts using real topography.
SewerCAD can open OpenFlows SewerGEMS models seamlessly, including those created within ArcGIS.
When modeling from MicroStation, you can enjoy a geospatial and engineering design environment with unrivaled visualization and publishing tools. If you are a AutoCAD user, you can also add the ability to run SewerCAD models from AutoCAD to build, lay out, and plot models with engineering precision in an environment with which they are already comfortable.
Gravity and pressure hydraulics
You can analyze pressure or free surface flow conditions using a robust gradually varied, standard-step algorithm in SewerCAD for solving subcritical, critical, and supercritical conditions, and complex composite profiles.
The steady-state simulation analyzes the system under extreme flow conditions. Automated design features are available with a steady-state analysis type to find cost-effective sewer designs. The extended period simulations (EPS) allow modelers to visualize how the system behaves over time. Results can be animated through time to locate hydraulic jumps and surcharging sections.
Wastewater loading allocation and estimation, and infiltration and inflow
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.
Automatic design of new systems and rehabilitation of existing sanitary sewers
The constraint-based design features in SewerCAD allow you to automatically design gravity piping and structures. The design is flexible enough to allow you to specify the elements to be designed, from a single pipe size to the entire system, or anything in between, by simply entering your design restrictions: minimum and maximum velocities, covers, slopes, and tractive stress; pipe and manhole matching offsets; and allow (or not) drop structures. SewerCAD will automatically determine cost-effective pipe sizes and invert elevations, avoiding unnecessary pipe trench excavation.
Comprehensive scenario management
The SewerCAD Scenario Management Center gives you full control to configure, run, evaluate, visualize, and compare an unlimited number of what-if scenarios within a single file. You can easily make decisions by comparing unlimited scenarios, analyzing rehabilitation alternatives for multiple planning horizons, and evaluating pump operation strategies, or overflow scenarios with varying future wastewater flows.
