To run WaterSums software, your computer must meet the following requirements:
Operating System
- Windows XP (SP3),
- Windows Vista, 32-bit or 64-bit (SP2), or
- Windows 7, 32-bit or 64-bit
Support Software
- Microsoft .NET 2 (SP1) or above
- Microsoft Silverlight 4 or
- Adobe SVG Viewer 3.0.3
Hardware
- 50 MB available hard disk space
- at least 2 GB of RAM
- 1.8 GHz or faster processor
- Dedicated graphics card for network flow animations
WaterSums Software
Designing and maintaining water supply networks has many different demands. One common requirement is to provide water from an existing network to a new sub-division. A designer must answer many questions, including:
- Where is the best supply point and what size of main is required?
- Would two supply points be better?
- Will any enhancements to the existing network be necessary?
- Are booster pumps or a storage tank required?
- What if another nearby sub-division also needs supply soon?
- Is any extra water treatment necessary?
- If demand increases by 20% or 30%, will supply pressure still be adequate?
WaterSums makes it easy to answer these questions and to optimise the new network layout. With WaterSums, you can have confidence that your design will work.
EPANET Feature comparison
WaterSums provides the complete anaylsis facilities of the EPANET toolkit, but lacks some of the features of the EPANET Windows software.
Over time, it is expected WaterSums will provide most of those features, but in the meantime, WaterSums development has concentrated on providing extra features that make design work quicker and easier.
Since WaterSums provides the ability to export network information in the EPANET format, the excellent and free EPANET software can still be used if specific features are required.
WaterSums offers many extra user-friendly features not found in EPANET. Some of these features are listed below:
- Referential integrity checking
- Warning on deletion
- Property value validation
- Multiple networks per project
- Project tree
- Automatic contour generation
- Simple flow direction animation
- Drag and drop import of EPANET input and network files
- Unlimited Undo/redo
- Auto-analyse
- Rule editor with syntax highlighting and validation
- Context sensitive help
- Tank levels displayed proportionally
Water Quality
WaterSums can help water suppliers improve the quality of water delivered to consumers.
WaterSums uses the EPANET analysis toolkit to model water age and the growth and decay of substances that effect water quality. With this powerful tool, you can study the effectiveness of existing treatment regimes and plan further enhancements to your network with confidence. Different pumping schedules and tank levels can be safely evaluated to minimise water age. Future pipe cleaning and/or replacement can now be planned with more confidence. With WaterSums, many different options can be evaluated in the safety of the office; only the optimum solution is then applied in the field.
The water quality analysis provided by WaterSums can give you cost-effective analysis and still ensure confidence that consumers are receiving water of the quality they expect.
In summary, the EPANET water quality analyzer used by WaterSums can:
- Model the movement of a non-reactive tracer material through the network over time
- Model the movement and fate of a reactive material as it grows (e.g., a disinfection by-product) or decays (e.g., chlorine residual) over time
- Model the age of water throughout a network
- Track the percent of flow from a given node reaching all other nodes over time
- Model reactions both in the bulk flow and at the pipe wall
- Allow growth or decay reactions to proceed up to a limiting concentration
- Employ global reaction rate coefficients that can be modified on a pipe-by-pipe basis
- Allow for time-varying concentration or mass inputs at any location in the network
- Model storage tanks as being complete mix, plug flow, or two-compartment reactors
Software Development Plans
WaterSums is still under energetic development.
WaterSums software is built on a foundation of incremental development. Frequent updates are expected and WaterSums software looks for updates on this website every time it starts - if you have an internet connection available. If an update is found, you are offered the opportunity to upgrade or to refuse the upgrade.
This is the development plan. Man proposes, God disposes.
Version 2.0 – expected Q2 2011
Includes significant architectural upgrades, a platform for later features in the Version 2 family of releases. The changes include:
- WaterSums now includes a Django internal server with GeoDjango to provide the additional option of storage of projects in a PostgreSQL/PostGIS database.
- A new, more flexible installer.
- Various technical upgrades:
- Silverlight display upgraded to Microsoft Silverlight 4,
- Display now uses csExWB browser component,
- Upgraded Proj.4 transformation library to Release 4.7, and
- Application is built with Microsoft VS2010,
- Support for Microsoft Windows 2000 has been removed.
Version 2.0.z – iterative releases during 2011
Iterative development releases are expected every 1–3 months. As well as bugfixes, these releases are expected to include the following extra features during the year:
- Background map display,
