The Detroit Water and Sewerage Department (DWSD), one of the largest water and sewer utilities in the United States, has a rich history as a public utility dating back to 1836.
Serves 35% of Michigan’s Population including Detroit and 76 other communities.
Fresh Water System - 5 water treatment plants pump an average of 596 million gallons of clean drinking water each day. Maximum capacity 1.2BGD
Wastewater System - Treats an average of 707 million gallons of flow per day. Maximum capacity 1.65BGD
Multitude of HMI solutions: Ovation, Wonderware, Ifix, RSView32
Large variety of systems integration implementations Disparate process control implementations Usually only hardware platform specified PLC Code developed using only written narratives No standard control software strategies No standard graphics, other than color standard Implementation varies by Contractor/SI/Programmer
Reduce the engineering time required to create standard, repeatable process applications
You can focus your energies on the custom aspects of your applications. Increase control system quality and reliability.
The reuse of well tested code conforming to industry standards reduces the likelihood of code bugs.
Drive logical and visual consistency The Process Library aids in producing standard Graphics formats that increase the consistency of your HMI thus reducing the need for Operator Training.
Superior diagnostics Built in process diagnostics will make applications easier for operators and maintenance to troubleshoot and debug without requiring PAC programming tools
Scalability – You can build ever larger systems using the same reusable modules.
Modular Programming Concept Use industry standard format -ANSI/ISA-S88
Create reusable application code based on “Best in Class” designs
Faster and easier development of application software. Examples of proven software programming techniques and recommended programming styles are provided for programmers to use in their own code.
Faster and easier testing of application software. Standards make testing of modular software objects easier, as there is less chance that new software developments will impact existing software objects that are already proven.
More reliable application software. The standards described ensures that changes to one software object will have little or no impact on another.
Improved maintenance and operation of application software The standardized look and feel of the automation controller programming and the human machine interface (HMI) for graphic objects makes it easier for operators and software personnel to recognize application functionality across applications and suppliers.

Hubbell-Southfield CSO RTB The Hubbell-Southfield CSO RTB is one of DWSD’s most active, longest operating CSO facilities and the largest on the Rouge River. Since August 1999, it has been effectively capturing and treating combined sewage through screening, settling and disinfection to meet discharge permit requirements that protect public health. Sized to fit into the available land and site constraints, the basin has a 22 million gallon storage capacity. Located next to the Tournament Players Championship Golf Course (TPC) in Dearborn, this RTB serves as an example of how these facilities can be good neighbors and blend in with the surrounding environment. The facility features an innovative design component that enables three different operational modes within the RTB and prevents resuspension of solids during large storms with high flow rates.
Puritan-Fenkell CSO RTB Located in Eliza Howell Park, the Puritan-Fenkell CSO RTB is the third Rouge River CSO RTB. This facility successfully demonstrated that a facility sized to provide 20 minutes of detention time for settling and disinfection of the 1-year, 1-hour storm event peak flow is sufficient to meet protection of public health standards. The 2.8-million-gallon facility became operational in August 1999 and eliminated two untreated CSO outfalls.
Results-Total construction costs significantly below estimate
Reduced Deployment Time • Resulted in a 50 percent reduction in design time, contract oversight, and post-contract
documentation and support. • Provided process control with advanced networking and diagnostic capabilities • Increased access to process data for better preventive and predictive maintenance
Reduced Engineering Hours and Costs • Saved estimated $120,000 in configuration and systems integration time • Saved $90,000 in factory-acceptance testing and Startup/commissioning
Drove standardization for DWSD wide graphics FTViewSE/ME platform
Advanced HMI without the associated development cost
Software configuration that is fully documented and tested
