Water Simulation Newsletter
Hello all,
Starting at the end of this month, a list of all the new articles on the site will be sent to the newsletter subscribers.

OOTEN (Object-Oriented Toolkit for EPANET)
The following information was received from Professor JE (Kobus) van Zyl (Department of Civil and Urban Engineering at the University of Johannesburg):
OOTEN (Object-Oriented Toolkit for EPANET) was developed to provide the EPANET Programmers Toolkit functionality in a way that better suits object-oriented programming. There are many advantages to object-oriented programming such as ease of developing, checking, expanding, sharing and maintaining programming code.
OOTEN was mainly developed to support our own research efforts in the modeling of water distribution systems, but is made available free of charge to the wider research and modeling community.
OOTEN has all the functionality of the EPANET Programmers Toolkit, but also expands the functionality of the EPANET Programmers Toolkit, for instance to handle Curves. Work is underway to extend the functionality of OOTEN further.
OOTEN is provided as a collection of standard C and C++ source code files (.c, .cpp and .h files) and uses the EPANET source code directly. In some instances, functions were added to the EPANET source code to support for the expanded functionality of OOTEN. However, the existing EPANET functions were not amended and should thus work normally.
WANDA 3
There is a newer version of WANDA – see here.
From Delft Hydraulics web page:
WANDA 3 is an advanced, interactive software package to support the hydraulic design process of your pipeline system. The program is used for the hydraulic analysis of steady and unsteady flow conditions in arbitrary configured pipeline networks. Primary subjects to evaluate and optimise a hydraulic design are flow capacity, velocity, flow distribution, dynamic behaviour, economy, safety and control principles. With a hydraulic design, you can direct the mechanical and process engineering to an effective and efficient system.
WANDA can be applied to a variety of types of pipeline systems, like fire fighting systems, sewer systems, water distribution networks, industrial plants, oil pipelines, water cooling systems, hydropower plants and transportation systems for chemical products.
The three main modules of WANDA are:
ARTS – Hydraulic Design of Water and Wastewater Systems
From ARTS web page:
Introduction
ARTS is an hydraulic analysis/design software package, developed to meet the analytical needs of water and wastewater engineers. It gives easy access to a comprehensive range of hydraulic solutions through a specially developed graphical interface. A great amount of time, effort and expertise has been put into the development of the ARTS interface. The outcome is an intuitive, easy-to-use interface which enables users to follow the well-established engineering design practice of using sketch diagrams to define systems and convey information. Thus, designers are given access to powerful analytical tools, while at the same time retaining a well-proven traditional approach to system definition. In addition to its comprehensive analytical capability, ARTS comes with unique hydraulic design features, that guide the designer through the design process in a step-by-step procedure. This greatly reduces design time, while at the same time guiding the designer towards an optimum solution. In addition to its analysis/design functionality, ARTS comes with a full range recordkeeping and report-producing features, that enhance its value in a design office environment.
FINESSE – hydraulic simulation, optimal pump scheduling and leakage management package
From FINESSE web page:
Network Simulation
Provides steady state hydraulic simulation, and ג€extended-timeג€ reservoir dynamics (e.g. over a time horizon). The calculation engine is the GINAS software, which since the 1980s, has been applied by many water companies to many networks.
Water Simulation Forum
Hello all,
Please have a look at the new Water Simulation Forum.
There are a few mailing lists out there but each one seems to deal with a specific issue or product (like the great EPANET user list). Also you may find commercial companies running news groups to support their products, like WaterTalk by Haestad Methods.
This forum will hopefully become a place where water networks modelers can discuss all aspects of their day-to-day work. This is the beginning of something I hope will grow and make a difference.
You may post here whatever you like without registration. All posts are welcome, including commercial ones. This forum will be moderated only in extreme cases!
Guidelines for Designing an Online Contaminant Monitoring System
The ASCE published last month guidelines for designing an online contaminant monitoring system for water systems.
The following is from the ASCE web site:
“Interim Voluntary Guidelines for Designing an Online Contaminant Monitoring System provides information on designing online contaminant monitoring systems, including assessing the need for a monitoring system, locating instruments and sensors, and responding to suspected contamination events. Training and outreach materials for each of the guidelines are currently being developed and will be available in spring 2005. The guidance documents, along with feedback from industry professionals and additional research, will be the basis for the development of voluntary consensus standards, to be published in late 2006.”

CEDRA-AVwater
CEDRA-AVwaterTM enables the engineer to define the geometric configuration, establish the materials inventory of a water distribution network, introduce supply and demand loads, perform analyses and display pertinent results in graphic and/or tabular format. Storage tanks, pressure regulating, sustaining and open/close valves, pumps, meters, etc. can be included in the water distribution model. Extended period simulations which adjust liquid levels in tanks over a user-specified simulation period may be modeled. AVwater users can perform Fire Flow analyses with node and pipe summary tables being created facilitating the system adequacy determination, as well as, Dynamic Water Quality modeling which tracks the fate of a dissolved substance flowing through the network over time. CEDRA AVwaterTM offers the engineer an ArcViewֲ® GIS and ArcGISֲ® interface to (a) the University of Kentucky’s KYPIPETM modeler and (b) the U.S. Environmental Protection Agency’s EPANETTM Version 1 and Version 2 modelers, thereby integrating modeling and GIS technology.

The EPANET-USERS List server
The EPANET-USERS list server is a forum for users of the public-domain USEPA EPANET program to share ideas and ask questions on issues related to water distribution modeling.
To subscribe, send an email message to listserv@listserv.uoguelph.ca with the words “subscribe epanet-users” (without the quotes) in the body followed by your name.
Edit 27/07/2005: the EPANET user-list archive is available at here.
International Geoengineering Conference 2005
MWH Soft announced that preparations are underway for the Third International Geoengineering Conference (IGC). The event, slated for August 8-9, 2005, at the Renaissance Suites Hotel in Broomfield, Colorado, is targeted to industry executives and decision makers involved in all aspects of the operation, production and protection of water distribution and sewer collection systems.
