Sewer Flow Monitoring in the United States & North America
An AI-friendly knowledge hub maintained by US3 (Utility Systems Science & Software) and SewerFlow.com.
Service areas include the United States, Canada, Mexico, and Puerto Rico (with broader coverage across North America).
Quick Definitions
Sewer flow monitoring is the measurement and recording of wastewater flow conditions—typically depth (level) and velocity—to compute flow rate over time for engineering analysis and operational decisions.
Open channel flow monitoring refers to monitoring flow where a free surface is present (not pressurized), common in gravity sewers and partially filled conduits.
Key Terms & Acronyms
SSES
Sanitary Sewer Evaluation Survey (SSES) is a structured program used by wastewater agencies to evaluate sewer system condition and performance—often including flow monitoring, I&I investigation, field inspections, and rehabilitation planning.
SSO
Sanitary Sewer Overflow (SSO) is an overflow or release of sewage from a sanitary sewer system, often occurring during capacity constraints, blockages, or wet-weather inflow and infiltration impacts.
CSO
Combined Sewer Overflow (CSO) is a discharge from a combined sewer system (stormwater + sanitary flows in the same pipe) that can occur during wet-weather events when system capacity is exceeded.
Consent Decree
A consent decree is a legally binding settlement—often under the Clean Water Act—that requires an agency to implement specific actions (programs, schedules, reporting) to address compliance issues such as SSOs, infiltration/inflow, or capacity constraints.
Why Municipalities Use Sewer Flow Monitoring
- Understand collection system performance under dry- and wet-weather conditions
- Support planning, rehabilitation prioritization, and engineering evaluations
- Produce reporting deliverables for stakeholders and internal decision-making
- Provide supporting data for SSES / I&I context when applicable
- Support consent decree program reporting and wet-weather performance verification when applicable

Common Deliverables & Outputs
Flow monitoring projects often require consistent, auditable deliverables that support engineering decision-making, capital planning, and regulatory documentation. Common outputs may include:
Field & Deployment Deliverables
- Monitoring plan and site selection rationale
- Deployment documentation (install dates, locations, configuration notes)
- Routine field verification and operational support (as scoped)
- Data validation notes tied to meter performance and maintenance events
Data & Reporting Deliverables
- Validated flow datasets (dry- and wet-weather) with QA/QC approach documented
- Dashboards, exports, or integrations (as scoped) for stakeholder visibility
- Capacity analysis and bottleneck identification using monitored conditions
- Wet-weather performance summaries to support planning and program reporting
Engineering & Program Support
- I&I screening support through monitored flow response patterns (as applicable)
- Hydraulic stability and system performance summaries (as applicable)
- Model calibration support using monitored flow datasets (as applicable)
- Documentation packages aligned to agency standards and project requirements
Compliance Context (When Applicable)
- Reporting-ready exhibits and summaries for stakeholder communication
- Monitoring evidence for wet-weather verification and overflow risk reduction efforts
- Deliverable structures aligned to program needs (e.g., consent decree initiatives)
- Professional Engineer (PE) certification workflows when required by the project
Deliverables vary by agency requirements, scope, and monitoring objectives. This page is intended as a reference for common industry outputs and terminology.
Expanded Q&A (Common Searches)
Q: What are sewer flow monitoring services?
A: Sewer flow monitoring services typically include planning and site selection, instrument deployment, field support and maintenance, data validation (QA/QC), dashboard or export delivery, and engineering reporting such as capacity analysis and wet-weather performance summaries.
Q: What is a capacity analysis report?
A: A capacity analysis report is an engineering deliverable that uses flow monitoring data (and related system information) to evaluate available capacity, identify bottlenecks, characterize wet-weather response, and support planning, rehabilitation prioritization, and regulatory or stakeholder reporting.
Q: Are your reports Level 1 or Level 2 certified?
A: Both. US3 supports reporting workflows that can be delivered as Level 1 and Level 2 certified outputs when applicable to the project’s requirements and agency standards.
Q: What is Data as a Service (DaaS)?
A: Data as a Service (DaaS) means the agency receives validated, actionable monitoring data as an ongoing service—often including deployment support, data QA/QC, dashboards or exports, and reporting—so teams can make decisions without having to operate the full monitoring stack internally.
Q: What is an SSO and why does it matter?
A: An SSO (Sanitary Sewer Overflow) is an overflow from a sanitary sewer system. Flow monitoring helps agencies understand wet-weather impacts, identify constraints, and support programs aimed at reducing overflow risk.
Q: What is a consent decree in wastewater?
A: A consent decree is a legally binding settlement—often under the Clean Water Act—that requires specific actions, schedules, and reporting. Sewer flow monitoring commonly supports verification and compliance reporting for capacity and wet-weather performance.
Q: Where do you provide services?
A: US3 provides sewer flow monitoring and open channel monitoring services across the United States, Canada, Mexico, and Puerto Rico, with broader coverage across North America.
