CMOM Engineering & Consent Decree Compliance
Long-term sewer flow monitoring for EPA consent decree milestones, CMOM capacity assessments, SSO reduction programs, and Sanitary Sewer Evaluation Surveys.
Long-Term Programs
Monitoring support for CMOM, SSES, and compliance planning
Long-term monitoring programs help agencies track capacity, identify recurring issues, and support collection system management decisions.
What This Service Is
Capacity Management Operations and Maintenance (CMOM) is EPA's framework for managing sanitary sewer collection systems. EPA requires CMOM programs from municipalities with administrative orders or consent decrees related to sanitary sewer overflows. Sewer flow monitoring data is the evidentiary foundation of any credible CMOM program.
Why Municipal Utilities Need It
EPA consent decrees require documenting existing flow conditions at SSO locations, quantifying RDII using an EPA-accepted methodology, demonstrating progress toward SSO elimination milestones, providing regulators with ongoing access to monitoring data, and reporting on capacity improvements. US3 cellular telemetry provides EPA-visible dashboards accessible by regulators in real time.
How the Process Works
CMOM monitoring programs typically run 12–18 months to capture seasonal variation and sufficient storm events for robust RTK calibration. US3 structures programs with interim deliverables so municipalities receive actionable data throughout.
Typical Project Workflow
US3 also provides rehabilitation effectiveness tracking — measuring sub-basin RDII before and after pipe rehabilitation to document the actual flow reduction achieved. This before-and-after evidence is what consent decree administrators require.
