Water Simulation Packages (WSP)

From the NEPLAN web site:

NEPLAN Gas, Water, District Heating - Analysis tool for gas, water and district heating networks.

NEPLAN is used to analyses, plan, optimize and manage gas and water pipeline networks. Any desired number of nodes and tubes can be quickly and interactively entered, computed and evaluated. NEPLAN is continually being enhanced, not least due to supportive empirical feedback and a fruitful dialogue between satisfied users and our development people. NEPLAN’s modular concept means that network planners can put together a planning system specifically tailored to their own individual needs.

“With financial help from the Pentagon, Israeli scientists develop a means for identifying any kind of water contamination. The well-equipped Israeli defense establishment may receive a significant addition by the end of the year - an artificial tongue.

Teams of scientists at three of Israel’s universities - Hebrew University, Tel Aviv University and Ben-Gurion University - have overcome a hurdle that was considered impossible to conquer and developed an apparatus capable of identifying every kind of water contamination.”

WaterCAD and WaterGEMS (Bentley Systems, Incorporated, Haestad Solutions Center) are a complete geographic information management system for your water utility in a cost-effective package that saves you money each time you use it. Analyze water quality, determine fire flow requirements, calibrate large distribution networks and more with WaterCAD’s powerful hydraulic analysis tools. WaterCAD is a sophisticated tool that enables engineers and decision makers to analyze and manage distribution networks with unprecedented accuracy and efficiency.

WaterCAD is the entry level product which solves for flow and pressure in piping networks with some enhancements in terms of:

• Scenario management
• Fire flow analysis
• Variable speed pumping
• System head curves
• Construction cost analysis
• Energy cost analysis
• Totalizing flow meter
• Import and export to and from a variety of data sources
• CAD polyline to pipe import
• Profiles
• Extraction of elevations from AutoCAD
• Export of model to transient analysis model
• Flex tables
• User defined data
• Model cleanup
• Quick edit
• Flex units

WaterCAD can be run as a stand alone model or from within AutoCAD.

PIPES++ is a program that does Single Balance or Extended Period Simulations of flow and water quality in a town water supply system. Fire flows can also be modelled.

Components that can be modelled include: Pipes, reservoirs, pumping stations, minor head losses, check valves, reservoir inlet control valves, various specialised control valves, pressure reducing valves, pressure sustaining valves, flow control valves and sprinklers.

You can draw the network on screen or you can import it from a DXF file, or from a GIS. Backgrounds showing streets etc can also be imported. Pipe flows may be calculated using either the Colebrook White equation or the Hazen Williams equation.

Results can be displayed on screen and customised (eg color coded for high and low pressures). Various graphs can be drawn (eg flow in a pipe, HGL at a node, water level in a reservoir). A summary of results can be pasted into a spreadsheet. Graphs can be printed or pasted into a word processor.

A working demo version and more information can be obtained from http://www.watercom.com.au. The on-line help system, available in the demo version, provides more detailed information on the capabilities of PIPES++.

“Since ancient times poets have revered the power of the seas. Now energy companies and coastal cities like New York and San Francisco are aiming to tap ocean waves and tidal currents as abundant sources of electricity.”

“Whether captured by big buoys bobbing on sea swells or by submerged turbines spinning with the ebb and flow of the tides, the energy potential of moving water, or marine power, is beginning to turn heads in the energy world.”

The following information was received from EDAMS Technology:

EDAMS Network Analysis brings you all the tools you need for fast and effective network design, analysis and optimisation. Its easy to use graphical interface and strong visual tools combined with its support for digital terrain modeling make it a uniquely powerful, yet intuitive, network analysis system.

EDAMS Network Analysis differs per type of service; at this stage it is available in two versions – Water and Sewer. Both share a common architecture based on industry-specific methodologies developed by EDAMS Technology over the last twenty years, but offer feature-sets reflecting their target fields.

EDAMS Network Analysis although has its own graphical abilities, it also links to GIS through demand and asset management systems for demand/ load generation and modeling live data.
Tightly integrated with other Utility products in the EDAMS Systems range, both EDAMS Network Analysis Water and Sewer provide extensive growth paths.

Form STANET web site:

STANET is an integrated application for network analysis. Besides calculation, graphic input, output and a database browser is included. The browser may be displayed together with the graphics. STANET may be used as a network information system because it uses standard dBASE-III database files, which may be extended by the user. Because graphics and database are using the same files, data exchange with other applications is simple.

FireHydrant.org is a free fire hydrant information resource. You will find thousands of photographs of different makes, models, and variations of fire hydrants, from the earliest examples of the 1800s to the hydrants of today. You will also find hydrant system design information, installation, testing and maintenance.

WASHINGTON (AP) — Water utilities have installed computer-based remote controls “with little attention paid to security,” leaving valves, pumps and chemical mixers for water supplies vulnerable to cyber-attack, according to an Environmental Protection Agency report.

The following information was taken from the Skat Foundation web page:

The Skat Foundation aims to contribute to the reduction of the gap between rich and poor through knowledge sharing and providing advice to partners in developing countries and countries in transition. It promotes sustainable improvement of the living conditions of the disadvantaged, particularly the poor, women and children.

In early 1998, the Swiss Centre for Development Cooperation in Technology and Management (SKAT) published a first edition of an “Overview of computer programs on drinking water distribution”. A selection of 10 widely used commercial software packages for designing and analysing piped water distribution systems was presented in a uniform and rapidly accessible format, based on information provided by the respective developers and distributors. The document responded successfully to an expressed demand from practitioners in developing countries who regularly addressed inquiries through SKAT, asking about currently available software for drinking water distribution systems design and analysis.
