SewerCAD

Exercise your platform freedom

SewerCAD is available in two compatible and interchangeable interfaces: Stand-alone and AutoCAD. Choose the environment that best fits your skills to facilitate and optimize your modeling workflow.

The stand-alone interface offers unparalleled ease of use and versatility, multiple background support, and conversion utilities from CAD, GIS, and databases. The AutoCAD interface is designed for users that want a higher level of precision by leveraging AutoCAD's drafting tools, seamlessly integrating their SewerCAD models in a CAD environment.

Minimize your capital investment

Let SewerCAD automatically design an entirely new network, or sections of an existing one, by simply entering your design restrictions: velocities, slopes, cover depths, and pipe and manhole matching offsets. SewerCAD will recommend the most cost-effective pipe sizes and invert elevations, avoiding unnecessary pipe trench excavation.

Assess capital costs associated with the collection and pumping systems automatically with SewerCAD's Capital Cost Manager. Recommend future improvements based on both hydraulic impact and construction cost.

Look at sewers the right way

System profiles are the best way to visualize potential bottlenecks and improvement opportunities, and they are just a couple of clicks away with SewerCAD.

Build profiles through both gravity and pressure sections, animate hydraulic grade lines and annotation through an Extended Period Simulation, save and recall profiles to avoid recreating them from scratch, and create templates with your specific design requirements.

Find more time for engineering

Time-saving features help you streamline data entry and leave you more time for engineering and decision-making. Use flexible tabular reports, maintain your own engineering attribute libraries for faster data input, and manage engineering units on the fly.

Jump-start your model with existing data

Leverage virtually any data source to jump-start your model building process and get your model up and running in no time. If you already have CAD drawings, GIS files, or external databases for your sewer system, you are only a few clicks away from having a SewerCAD model of your network. Bidirectional connections between shapefiles, databases, spreadsheets, and your SewerCAD model help you make changes to your model as your source data changes.

Easy load estimation

SewerCAD’s sanitary loading features help you to accurately estimate dry and wet weather contributions to the collection system.

Use customizable unit load libraries for estimation based on contributing population, service area, and total dry weather discharge, or build your own loading types. Select from pre-defined extreme flow factor methods including Babbit, Harmon, Ten State, and Federov’s, or implement your own.

You can also determine infiltration based on pipe length, diameter, surface area, length-diameter, or user-defined data, and manage multiple flow hydrographs for Extended Period Simulations.

Control of gravity and pressure hydraulics

Analyze pressure or free surface flow conditions using SewerCAD's robust algorithm* for solving for subcritical, critical, supercritical conditions, and complex composite profiles.

Run steady-state analyses to evaluate your designs under extreme flow conditions, while extended period simulations help you visualize how the system behaves over time, helping you locate hydraulic jumps and surcharging sections. Simulate real-time controls with SewerCAD turning pumps on and off based on time, flows, pressures, and wet well levels, among other criteria.

You can choose from different friction methods like Manning, Kutter, Darcy-Weisbach, and Hazen-Williams, and calculate structure headloss with a variety of methods including FHWA HEC-22 and AASHTO.

*SewerCAD uses a gradually varied, standard-step algorithm. For a dynamic engine that solves the full Saint Venant equations, check out Bentley's SewerGEMS.

Organize scenarios for better decision

The exclusive Scenario Control Center helps you organize an unlimited number of physical, design, hydrology, network topology, and operational scenarios to make faster and accurate decisions with a single SewerCAD file.

Sound decision-making for your sanitary sewer system requires the consideration of multiple engineering scenarios, such as:

• Rehabilitation alternatives for multiple planning horizons
• Pump control strategies for energy-saving operation
• Sewer design approaches with varying peak flow methods
• Overflow scenarios with varying future wastewater flows

Understand results easily

Spot bottlenecks and potential surcharging with animated 3D graphs and profiles, use property-based color coding, element symbology, and annotation to easily visualize your input and results, and create tabular reports, system-wide summaries, and project inventories on the fly.
