Detroit Water and Sewerage Department
DWSD implements a multi-year program of technological improvements
The Detroit Water and Sewerage Department (DWSD) is the third largest water and sewer utility in the United States with service dating from the early 1800s. The Department provides water service to approximately 4.3 million people in southeastern Michigan, pumping an average of 675 million gallons of drinking water daily. Its wastewater treatment facility treats an average of 720 million gallons of flow daily.
The Department needed to improve and expand its process control and monitoring capabilities, enhancing the ability to reliably produce and distribute quality drinking water and collect, transport, and treat wastewater.
Westin helped DWSD establish a modern process control and monitoring system to allow coordinated operation of DWSD’s water and wastewater treatment facilities. Westin’s staff served as the Owner’s Representative, providing DWSD with specialized instrumentation and control expertise, contract oversight, and program management.
Through completion of this $292 million project, the Department was able to significantly improve and expand its process control and monitoring capabilities, enhancing the ability to reliably produce and distribute quality drinking water and collect, transport, and treat wastewater throughout the southeastern Michigan service area. The successful project outcome includes:
- A thoroughly tested and documented system that provides efficient, reliable service and a complete view of the processes and process communications network
- A secure network and data repository to maintain data integrity and enable access to and use of process data
- Well-trained operators, supervisors, managers, and technical staff who are extending the capabilities of the system and improving process performance by implementing creative approaches
- Widely and instantly available operational information for real-time control and monitoring as well as high-level decision making, planning, and predictive analyses
- Complete monitoring and reporting capability for regulatory compliance, and
- Long-term (seven years after completion of construction) maintenance and calibration of all signals connected to the control system to optimize the system’s value to the Department.
DWSD’s control system is completely redundant, and constructed with scalable architecture for flexibility and adaptability to accommodate future system requirements.
