Advanced Water Distribution Software WaterPack is a fully-dynamic EPANET based water distribution modeling package. It can analyze an entire water distribution system, or selected portions, under steady state or extended period simulations, with water quality analysis if needed.

Sophisticated GIS Capabilities

WaterPack can share water distribution data with any ArcGIS database, allowing WaterPack to be part of the infrastructure management and planning system. These capabilities can greatly assist in the decision making processes for network asset inventory, rehabilitation requirements, and financial planning. WaterPack can intelligently build a link to any GIS database structure using attribute mapping and geo-coding. For example, a pump or valve can be represented as either a node or arc in the originating GIS database, while still being linked with WaterPack.

Powerful Report Generation

Comprehensive input data and output analysis reports can be automatically generated using the provided report templates. WaterPack allows full customization of input and output reporting using its built-in report generator. This powerful database reporting and query tool, integrated directly into WaterPack, provides a streamlined approach to creating reports. This allows the user unlimited flexibility and functionality in developing specialized user-defined reports. These reports can be fully customized to meet any combination of modeling criteria for any network variable and for any time period, or for simply adding a corporate logo, etc. Furthermore, due to WaterPack’s open-architecture Microsoft Access database engine, nearly any other reporting tool can be used to generate reports from WaterPack.

Computational Analysis Engine

WaterPack computational analysis engine has extensive modeling capabilities. The program supports any network configuration and multiple demand categories. WaterPack can very efficiently handle large models and complex systems with multiple pressure zones for any hydraulic condition. WaterPack is based upon the industry-standard EPANET version 2.0 water quality model-meeting and exceeding the EPA Clean Water Act Standards. It uses the rigorous Hybrid Method, which is the most powerful and computationally efficient method of network analysis. Pipe frictional loss computations can be performed using Hazen Williams, Darcy Weisbach, or Manning equations. WaterPack uses sophisticated rule-based control valves, pumps, and tanks (based upon time, tank water levels, and nodal pressures) to simulate the exact behavior of any water distribution system.

WaterPack will track the flow and velocity of water in each pipe, the pressure and grade at each node, the height of water in each tank, and the movement and fate of water quality constituents (such as chlorine, chloramine, trihalomethane, total dissolved solids, nitrates, hardness, fluoride, etc.) throughout the entire network during a dynamic simulation. WaterPack accurately models phenomena such as first-order reactions within the bulk flow, pipe wall, and storage tanks. A global kinetic rate coefficient can be assigned for the entire network or user-specified values can be assigned to selected components. Water age, travel time, and constituent source tracking can also be performed.

The analysis engine allows modeling of “what if” scenarios, allowing the engineer to specify multiple modeling alternatives on the same pipe network. These alternatives can include user-selected changes in network configurations, demand loading conditions, and changes in physical system characteristics. WaterPack’s analysis engine can be run interactively, or in batch mode-automatically running several different scenarios on the same network. Either method allows rapid and efficient analysis of multiple modeling alternatives.
