Capacity, Management, Operation, and Maintenance Framework

What is CMOM?

CMOM stands for Capacity, Management, Operations, and Maintenance. CMOM is an ongoing management framework that supports the planning, operation, maintenance, inspection, documentation, and improvement of the Milwaukee Metropolitan Sewerage District’s (MMSD) wastewater conveyance system, wastewater treatment facilities, and watercourse systems. It is intended to be reflected in daily work activities such as preventive maintenance, inspections, condition assessment, regulatory compliance, emergency response, asset management, capital planning, and coordination between MMSD and its contract operator.

Why did MMSD implement and continue to operate a CMOM Program?

MMSD originally implemented its CMOM Program as part of a 2002 Stipulation Agreement with the State of Wisconsin and because MMSD recognized CMOM as a valuable tool in support of its mission to protect public health and improve water quality. MMSD continues to operate the program because it provides a structured and documented approach for managing infrastructure, supporting regulatory compliance, reducing the risk of system failures, evaluating whether established practices are being followed, and identifying opportunities for improvement.

What has MMSD done and continues to do regarding its CMOM Program?

MMSD developed its CMOM Program through readiness review, strategic planning, and program development, which was completed and submitted to the Wisconsin Department of Natural Resources on June 29, 2007. Since that time, the program has continued as an active compliance and management framework through ongoing documentation, auditing, and corrective actions to ensure the program remains current, useful, and aligned with MMSD’s operating responsibilities and water quality mission.
