EPANET 2.0 (1 383kB)

Developed by EPA's Water Supply and Water Resources Division, EPANET is software that models water distribution piping systems. It is a Windows 95/98/NT/XP program that performs extended-period simulation of the hydraulic and water quality behavior within pressurized pipe networks. Pipe networks consist of pipes, nodes (pipe junctions), pumps, valves, and storage tanks or reservoirs. EPANET tracks the flow of water in each pipe, the pressure at each node, the height of the water in each tank, and the concentration of a chemical species throughout the network during a simulation period. Chemical species, water age, source, and tracing can be simulated.  EPANET provides an integrated computer environment for editing network input data, running hydraulic and water quality simulations, and viewing the results in a variety of formats. These include color-coded network maps, data tables, time series graphs, and contour plots.  EPANET is public domain software that may be freely copied and distributed. The Open User Guide is included

OpenWorkbench (10 945kb)

OpenWorkbench is a robust, mature tool for project scheduling and management. It conforms to and supports the underlying ideals of project management while presenting information in a way that is intuitive and easy to learn. Tens of thousands of project managers around the world use Open Workbench to plan and execute complex projects.

All projects proceed through a series of tasks (or stages) during their lifecycle. By using Open Workbench, these critical tasks or stages become more manageable, making projects more likely to succeed. Open Workbench enables project managers to create work breakdown structures (WBS) with tasks and milestones, set baselines, schedule project plans with dependencies, assign resources to tasks, schedule work on tasks over a period of time, adjust the schedule as actual work is recorded, link master and subprojects and schedule resources across them, and conduct earned value analysis.
