SewerCAD is an easy-to-use sanitary sewer modeling and design software product that thousands of municipalities, utilities, and engineering firms around the world trust to design, analyze, and plan wastewater collection systems. Engineers can model both pressurized force mains and gravity hydraulics with ease, using steady-state analysis with various standard peaking factors, and extended-period simulations. Engineers 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. The LoadBuilder module included in SewerCAD helps engineers 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. Modelers can use totally customizable unit load libraries to estimate sanitary flows based on contributing population, service area, total dry weather discharge, or their own customized loading types. SewerCAD also includes numerous pre-defined extreme flow factor formulas and tables, including Babbit, Harmon, Ten State, and Federov’s – or lets users enter their 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. The constraint-based design features in SewerCAD allow modelers to automatically design gravity piping and structures. The design is flexible enough to allow users to specify the elements to be designed, from a single pipe size to the entire system, or anything in between, by simply entering their design restrictions: minimum and maximum velocities, covers and slopes; 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.

StormCAD is a comprehensive modeling software program for the design and analysis of storm sewer systems. StormCAD provides calculations for catchment runoff, inlet capacity, and gutters and pipe network flow. StormCAD determines intercepted flow at network inlets, and routes bypass flow to selected bypass targets. Inlets can be computed using the U.S. Federal Highway Administration (FHWA) HEC-22 methodology and users can choose from grate, curb, slot, ditch, and combination inlet types. Engineers can use a variety of methods to compute headloss, including HEC-22 Energy and AASHTO. StormCAD uses the Rational Method to calculate peak flows in the storm sewer design, or accepts direct input of known flows for inlet inflows. StormCAD allows users to specify Intensity-Duration-Frequency data using equations or tables. Modelers can then plot the IDF curves, and reuse their data for other projects in that region. Engineers can work with an unlimited number of sub-watershed areas and C coefficients for each inlet watershed. The constraint-based design features in StormCAD allow modelers to automatically design gravity piping and structures. The design is flexible enough to allow users to specify the elements to be designed, from a single pipe size to the entire system, by simply entering the appropriate design conditions: minimum/maximum velocities, covers, and slopes; pipe elevation offsets (including whether or not to allow drop structures), maximum spread and depth for inlets in sag; and minimum efficiency for inlets on grade.

If building and preparing your sewer models feels like a never-ending task, SewerGEMS software is for you. SewerGEMS streamlines the modeling process, so that you have more time for solving wastewater engineering problems, such as improving capacity and limiting sewer overflows, which ultimately enable utilities to comply with sewer regulations set by regulatory agencies. For more than three decades, SewerGEMS has provided utilities and wastewater professionals like you with advanced engineering tools to plan, design, maintain, and operate sanitary and combined sewer systems, including:

• Engineering decision guidance tools: Leverage SewerGEMS’ what-if scenario management tools to gain a better understanding of the behavior of your wastewater system, improving decision making and response time.
• Improved model accuracy: A well calibrated model decreases the risks of making poor decisions by ensuring that the model uses the best available data. SewerGEMS calibration tools such as SCADA integration enable you to rely on your model results.
• Increased information mobility: SewerGEMS’ full GIS, CAD, and SCADA interoperability enables the cost-effective sharing and flow of information between utilities’ design, engineering, GIS, and operation departments, and their consultants. You can leverage the data that the utility invested in once and reuse across departments.

PATB is a program for block adjustment using the well-proven bundle method for highest accuracy specifications. Since it's initial public lauch in 1972, the program has been continuously further developed and upgraded according to the improvement of photogrammetric theory and the progress in new computer systems. Today, the actual version PATB-NT is one of the most advanced bundle block adjustment program worldwide. Highly optimized with regard to extreme numbers of observations and photographs, PATB shows stunning execution speed on Personal Computer systems. PATB-NT is about 3 times faster in execution than the preceding DOS version on the same computer system. Hundreds of companies and institutions confirm the intuitive self-explanatory user interface and economic program handling in daily practical work.

The calculation of all required initial values of the unknowns is done automatically from your data, without referring to preceding manual preparation. There are no restrictions concerning overlap, numbering systems, number of observations and block size. Self-calibration is used to correct simultaneously for systematic image errors. Different sets of orthogonal self-calibration parameters can be applied for the complete block or for groups of photographs to ensure an optimum accuracy. Automatic correction of earth curvature and refraction can be applied optionally. Automatic detection and elimination of blunders during the adjustment avoids tedious manual data cleaning. The method of robust estimators for data cleaning guaranties the detection of all possible data errors ranging from severe administrative numbering errors up to small measuring errors. Besides control point information, PATB allows the simultaneous adjustment of kinematic GPS observations with optional drift correction. The linear drift correction for the x, y and z co-ordinates of the GPS observations compensates for most of the errors caused by GPS drift, unavailable transformation parameters or transformation formula to your local terrain co-ordinate system, antenna offset, cycle slips and systematic errors of the perspective center co-ordinates. PATB also offers the possibility for rigorous error propagation and sophisticated statistical analysis based on the normal equation inverse. Geometrically weak areas in a network are then easily locatable. The standard deviations of the image orientation parameters and the final adjusted co-ordinates and their mean - and maximum values inform about accuracy and reliability of your AT block and its design. A graphical overview for the essential adjustment results provides an instant and thorough analysis of the adjustment results. These features of PATB ensure reliability and are the basis to achieve high accuracy specifications for a block adjustment even with minimum or no ground control points. PATB is the economic solution for your AT projects.
