Grand Rapids is the second-largest city in the state of Michigan, and the largest city in West Michigan. It is located on the Grand River about 30 miles (42 kilometres) east of Lake Michigan. The wastewater plant treats 17.9 billion gallons (~67 million cubic metres / ~67 billion litres) annually with a daily average of ~50 million gallons (~189,000 cubic metres / ~189 million litres) and a peak of 90 million gallons (~340,000 cubic metres / ~340 million litres) per day. The plant has a design capacity of 61.1 million (~231,000 cubic metres / ~231 million litres) gallons per day. Alongside the plant is the City’s Market Avenue Retention Basin. It has a storage capacity of 30 million gallons (~113,000 cubic metres / ~113 million litres) and a treatment capacity of 1.1 billion gallons (~4 million cubic metres / 4 billion litres) per year. The Primary Effluent Retention Basin has a storage capacity of 10 million gallons (~37,000 cubic metres / ~37 million litres).
In 2013, the City of Grand Rapids partnered with Eramosa to implement and enhance e.RIS, Eramosa’s Reporting and Information System. Building on the strong reporting foundation within e.RIS, our partnership worked to create an integrated module to format, generate, and export the City’s two Discharge Monitoring Reports (DMRs) as part of their National Pollutant Discharge Elimination System (NPDES) permit requirement. The team also worked together to meet the changing requirements encountered when the State of Michigan implemented the new web-based permitting and compliance database, MiWaters. The site offers a streamlined electronic permitting process, allowing the state to fulfill federal electronic reporting requirements and providing a portal for public information access.
The partnership continued to enhance e.RIS by collaborating to develop alarm triggered process workflows. By configuring e.RIS to regularly monitor specific SCADA alarm and/or event conditions, e.RIS can kick-off a workflow for staff to respond to. Links to support documents (for example, standard operating procedures, process documentation, etc.) and e.RIS reports can be included in workflow task assignments to help staff access the information required to complete assigned tasks. Once workflows are complete, e.RIS retains these for later reporting and review.
Lastly, Eramosa and the City developed a new electronic logbook module for e.RIS that is integrated with the plant’s asset management and maintenance management application, MaximoTM. As control room operators enter new logbook entries, they can reference any plant asset stored within MaximoTM. Hyperlinks within logbook entries permit operators to view open and closed MaximoTM work order summaries directly within e.RIS.
