The SRMP is a comprehensive 25-year planning document that provides the basis and schedule for rehabilitation and replacement of biosolids processing equipment and systems. During development of the SRMP, a variety of stakeholders participated as members of the project team and at public workshops, which resulted in recommendations for capital improvements that reflected community values.
Based on the results of the SRMP, WWTP staff initiated the RHI to implement the capital improvements recommended in the plan. The development of the design documents for the RHI has been a multi-year process. In 2005, Council authorized Greeley and Hansen, LLC (G&H), to provide professional engineering services to design the RHI, which will replace existing biosolids handling facilities while allowing the WWTP to remain in service during construction. After completing the design documents, G&H assisted WWTP staff in obtaining a construction permit from the Michigan Department of Environmental Quality. In addition, G&H assisted WWTP staff during an extensive site plan application and approval process with Ann Arbor Township, which is where the City’s WWTP is located.
