SmartCover Helps Water Utilities Optimise Sewer-Collection Systems

Abstract

This paper explores the integration of real-time, satellite connected remote monitoring technology in sewer collection systems to address growing challenges such as capacity constraints, inflow and infiltration (I&I), hydrogen sulphide (H₂S) corrosion, fats, oils, and grease (FOG) blockages, and climate-induced storm impacts. With aging infrastructure and increasing environmental regulations, cities are turning to smart sewer technology to proactively manage risks and improve operational efficiency. Case studies show real-world deployments of the ultrasonic monitors. The sensors transmit continuous data on flow levels, gas concentrations and blockages to a secure online dashboard and mobile app. These systems deliver realtime alerts, integrate with SCADA (Supervisory Control and Data Acquisition), and support CMOM (Capacity, Management, Operations, and Maintenance) programs by identifying emerging issues, such as overflows, backups, and over-cleaning, before they escalate. Findings show that cities using this technology gain 24/7 visibility of site conditions, enabling earlier, targeted interventions, reducing maintenance costs and preventing environmental incidents. Monthly SmartInsights reports summarise system performance, identify high-risk areas, and track progress against previous periods, providing actionable insights for both immediate operations and long-term planning. For the trenchless industry, this technology enhances asset longevity by reducing the frequency of emergency excavations, informing trenchless rehabilitation prioritisation, and improving data-driven decision-making. It shifts the approach from reactive to proactive, supporting sustainable management of underground infrastructure. The broader community benefits from fewer sewer overflows, lower greenhouse gas emissions, reduced disruption from emergency repairs, and improved regulatory compliance. Real-time remote sewer monitoring delivers environmental protection, improved safety and health conditions for staff and the public, and system and operational resilience.
