Optimize your network
A review of methods for leakage management in pipe networks. Urban Water Journal. Roy, B. Ross Eds. It performs fast, reliable, and comprehensive hydraulic and dynamic water quality modeling, energy management, real-time simulation and control, fire flow analysis, and with automated on-line SCADA interface. The program can also be effectively used to analyze pressurized sewer collection systems.
H2ONet MSX Multi-Species eXtension adds very powerful modeling capabilities including the unprecedented ability to accurately model multiple interacting contaminants using water quality components rather than contaminants as well as sediment deposition and re-suspension in drinking water distribution systems. H2ONet MSX allows users to model very complex reaction schemes between multiple chemical and biological species in the water distribution piping system, both in the bulk flow and at the pipe wall.

This structure gives users the flexibility to accurately model multi-source, multi-quality systems and a wide range of important chemical reactions including free chlorine loss, formation of disinfection byproducts, nitrification dynamics, disinfectant residuals, pathogen inactivation, chloramine decomposition, and adsorption on pipe walls. While there are a number of commercially available programs for modeling the hydraulic and water quality behavior of drinking water distribution systems, their water quality component is limited to a certain number of fixed kinetic models, and to tracking the transport and fate of a single chemical species, such as fluoride or free chlorine.
In addition, the program allows users to input any mathematical models of physical, chemical, and biological reactions in the bulk water and on pipe surfaces. It also accepts any number of user-specified adding water quality parameters and formulas for process models. H2ONet MSX can also be effectively used to track the movement, fate and build up of particulate material in the water distribution system. This feature can greatly assist water utilities in improving distribution design to minimize dirty water and forge closer ties with their customers. Another powerful and unique feature of H2ONet MSX is its critical ability to accurately simulate spatial and temporal variations in water temperature and temperature gradients throughout any water distribution system.
The physical and operational data required for the development of a network model can normally be obtained from maps of the water system, as-built drawings, operational records, and conversations with plant operators and city or utility engineers. To a certain degree the exact data requirements for a particular computer model will be somewhat dependent upon the options of the program. In general, all programs require a junction label, elevation, and water demand value for each junction node.
Similarly, most of program will require a pipe label, beginning and ending junction node labels, pipe length, diameter, and roughness of each pipe. Most programs allow the user to characterize the pipe roughness using either the Hazen-Williams equation or the Darcy-Weisbach equation. Some programs also allow the user to assign a minor loss to each pipe and to characterize various types of control valves i.
