Sewer Inspections with SewerBall

Inflow and infiltration (I&I) can place significant pressure on wastewater networks, increasing the risk of sewer flooding, combined sewer overflows (CSOs) and unnecessary treatment costs. Locating the source of these issues within complex underground systems is often time-consuming and expensive.

SewerBall addresses this challenge with a family of compact, sensor-equipped devices that travel through wastewater networks to identify and locate sources of inflow, infiltration, saline intrusion and pollution. 

By revealing real-world flow conditions, sediment accumulation, blockages and other network disturbances, SewerBall provides insights that traditional inspection techniques alone may miss. This allows utilities to identify emerging issues earlier, prioritise interventions and make more informed investment decisions.

Each SewerBall device measures key water quality parameters, including pH, temperature, conductivity and redox potential (ORP). Advanced analytics transform this data into actionable insights, delivered through a secure cloud-based platform.

SewerBall provides a rapid, low-disruption method for screening wastewater networks under normal operating conditions. The free-floating devices are equipped with cameras and require no sewer cleaning, no flow interruption and no confined-space entry.

By quickly assessing large sections of the network, SewerBall helps utilities identify priority locations for further investigation and target CCTV surveys where they will deliver the greatest value. This reduces unnecessary inspections, improves the efficiency of survey programmes and accelerates decision-making.

SewerBall's drop-and-go approach enables utilities to screen extensive sections of sewer network quickly and safely, without disrupting normal operations.

Suitable for free-flow sewer systems, SewerBall can be deployed in a wide range of operating environments, including difficult-to-access locations and assets that are challenging to inspect using conventional methods.

Rather than replacing CCTV inspection, SewerBall helps utilities focus CCTV resources where detailed investigation is most needed, improving survey efficiency and reducing wasted inspection effort

SewerBall delivers detailed insight into network condition, water quality and asset performance, helping utilities identify abnormalities, understand network behaviour and respond proactively to emerging issues. Using advanced analytics and automated interpretation, SewerBall converts raw sensor data into clear, actionable information that supports operational and strategic decision-making.

SewerBall helps utilities identify and locate:

• Inflow and infiltration
• Saline intrusion
• Industrial discharges
• Pollution events
• Sediment accumulation
• Network disturbances and blockages.

By providing intelligence from difficult-to-access and non-visitable assets, SewerBall helps utilities gain a clearer understanding of network condition and identify areas requiring further investigation.

Results are presented through intuitive maps, visualisations and automated reports, enabling teams to prioritise maintenance, target capital investment and improve network performance with greater confidence.

SewerBall enables utilities to:

• Locate sources of inflow, infiltration and pollution
• Reduce the risk of sewer flooding and CSOs
• Target CCTV inspections more effectively
• Prioritise maintenance and rehabilitation activities
• Improve asset visibility across the network
• Optimise operational and capital investment decisions
