From HYDRA web site:

HYDRA® software is a full-featured program used by environmental and civil engineers to model and design urban drainage systems. It helps you estimate wastewater flows, and then calculates the resulting hydraulics within the collection system. It provides tools for managing all types of flows, including sanitary wastewater, stormwater inflow, rainfall-dependent infiltration, and groundwater infiltration. It helps you understand how the whole sewer system works under various conditions — today and in the future - and identify potential problem areas. HYDRA® software creates preliminary design for new sewers and suggests improvements for existing systems. It helps you optimize your pipe network, and find the most cost-effective way to solve system problems. The HYDRA® program has been used by thousands of engineers since its first commercial release in 1973.

H2OMAP Water provides the most powerful and practical GIS platform for water utility solutions. As a stand-alone GIS-based program, H2OMAP Water combines spatial analysis tools and mapping functions with sophisticated and accurate network modeling for complete infrastructure (asset) management and business planning. It performs fast, reliable and comprehensive hydraulic and dynamic water quality modeling, energy management (with true variable speed pumping), real-time simulation and control with on-line SCADA interface, complete fire flow analysis, and unidirectional flushing. The program can also be effectively used to analyze pressurized sewer collection system.

Hydraulic Modeling Capabilities:

• places no limit on the size of the network and number of components that can be analyzed (unlimited link version)
• supports both English and metric (Standard International) units
• analyzes steady-state and extended period simulations
• computes friction headloss using the Hazen-Williams, Darcy-Weisbach, or Chezy-Manning formulas
• includes minor (local) head losses for bends, meters, fittings, etc.
• models constant or variable speed pumps
• models a fixed pressure pump (FPP) that automatically adjusts its speed to maintain a user specified target pressure (or head) anywhere in the system
• models turbines and totalizing flow meters
• calculates Net Positive Suction Head requirements (available NPSH, required NPSH, and cavitation index) to ensure cavitation free operation
• determines system head curves and fire hydrant rating curves
• calculates available and design fire flows at minimum residual pressures
• computes pumping energy and cost based on variable electricity and demand charges
• accommodates various types of static and dynamic control valves including shutoff, check, float, pressure reducing, pressure sustaining, dual pressure regulating (maintain downstream and upstream pressures), pressure breaker, vacuum breaker, motorized throttled, general purpose, flow control, and reduced pressure backflow prevention valves
• allows single and multiple inlet/outlet storage tanks to have any shape (i.e., diameter can vary with height)
• models constant and variable head reservoirs
• considers multiple demand categories at nodes, each with its own pattern of time variation
• models pressure-dependent demand issuing from emitters (sprinkler heads)
• automatically carries out pressure-demand analysis to compute the percentage (%) of demand supplied to each node (ratio of actual demand vs specified demand)
• tracks flow reversals for pipe flushing
• determines pipe sequences for unidirectional flushing
• simulates leakage in a pipe
• specifies system operation based on both simple node pressure, tank level, link flow, or timer controls and on complex rule-based controls
• provides on-line SCADA interface with alarms

From Derceto’s web site:

The only “customized off-the-shelf” (COTS) software tool which works online and in real-time to reduce the costs of treated water distribution, Derceto optimizes pump schedules to minimize distribution costs guided primarily by electricity tariffs. Direct connection to the SCADA system provides live data, which is then used by Derceto to choose the lowest cost sources of water as well as distribution and booster pump schedules. Derceto calculates the minimum cost solution from the multitude of possible pump schedule combinations to meet the day’s evolving demand while maintaining defined constraints such as water turnover and storage requirements.

The following information was received from ATMOS International:

ATMOS LSIM is a modern pipeline simulation software that calculates liquid flow, pressure, density, temperature and other variables under steady state, transient and shut-in conditions. Using a fully graphical configuration tool, LSIM models pipes, valves, tanks, filters, heat exchangers, leaks, supply and delivery points.

Complex control mechanisms can be implemented for pumps and valves based on PID (Proportional-Integral-Derivative) and logic controllers.

LSIM is fully OPC (OLE for Process Control) compliant, making it possible to synchronise an off-line simulator with a real-time system. The simulation boundary condition could be a fixed value, a user-defined profile or an OPC tag from a SCADA system. All model calculated values can be saved in a database, trended graphically and output to a SCADA or other computer
systems using OPC.

LSIM simulates dynamic flow of single liquid, batched fluids, mixed fluids and vapour pockets. For the simulation of batched fluids, batch interface volume can be calculated together with the interface position and length.

With a configurable grid length from 0.5 meter to tens of kilometers, LSIM is accurate enough for detailed surge analysis and fast enough for operational scenario analysis and planning.

More information can be found at ATMOS International web site.

Simulation & optimization of water supply networks. From the University of Karlsruhe web site:

KANET Simulation
KANET Simulation performs the time extended hydraulic network balance of a reticulate system whose graph, diameters, pipe material or friction factors, flow input and demand, characteristics of pumps, boosters, valves, location of tanks, pumping stations, valves are known. The model also allows for tracing the propagation of an input concentration.

KANET Optimization
KANET Optimization delivers cost optimal diameters and pumping heads of a reticulate water supply network based upon a specified design demand and subject to constraints such as max velocities, min supply pressure, location of pumps, tanks and reservoirs. Already existing pipes are taken into account, optimal tradeoffs between investment and operating cost are observed using the present value. Simultaneous optimization of the layout is included.

From “Applied Flow Technology” web site:

AFT Impulse provides a practical tool for the piping systems engineer to address the complex subject of liquid piping systems waterhammer and surge transient events. AFT Impulse incorporates an integral steady-state solver to calculate the initial conditions and seamlessly transfer these to the transient solver. Based on the same, proven solver in AFT Fathom, steady-state solutions are determined using a modified Newton-Raphson matrix interation. AFT Impulse’s transient flow solution engine is based on the Method of Characteristics, which utilizes time steps and pipe section lengths that are an integral fraction of the wave speed. This permits a direct solution of each time step, making AFT Impulse highly efficient.

AFT Impulse lets you specify transients both on a time and event basis. For example, initiate a pump startup based on the pressure at a selected location in the system or a valve closure upon the flow direction at selected location. This powerful capability greatly expands the type of transients that may be modeled including a variety of control logic functions.

Pump modeling can be as simple as a fixed flow or as sophisticated as pump curves and four quadrant effects modeling the various possible combinations of forward and reverse flow and rotation. Startup includes the ability to determine pump acceleration from specified pump/driver inertia and driver torque vs speed. Pump models may include integral check valves and reverse rotation brakes.
