Inflow, infiltration, and pollution identification

SewerBall incorporates water quality sensors designed to detect inflow, infiltration, and pollution, helping utilities prevent overflows, optimize operations, and target infrastructure investment.

Inflow and infiltration often cause system malfunctions and contribute to combined sewer overflow (CSO).

Locating affected areas within underground networks can be complex and costly. SewerBall solves this challenge with a family of compact, sensor-equipped spheres that float through wastewater networks to identify and locate inflow, infiltration, and pollutants.

As aging infrastructure, I/I, saline intrusion, and hidden asset degradation continue to increase operational costs, utilities need a faster way to screen entire basins and understand where problems are emerging. SewerBall provides that missing layer of intelligence by revealing real‑world flow behavior, sediment, blockages, and early warning signs that CCTV alone cannot detect.

The SewerBall family of devices measures pH, temperature, conductivity, and oxidation-reduction (ORP) potential. Data is analyzed using a dedicated algorithm, and results are delivered via a remote-access platform. 

Fast and flexible sewer inspection

The SewerBall family of free-floating, sensor-equipped devices rapidly and safely inspects wastewater networks, without the need for system cleaning or flow interruption. A SewerBall inspection is approximately 3 times faster per foot compared to CCTV.  

By screening large areas quickly and identifying hotspots, SewerBall helps utilities determine which pipes truly need a full 360° CCTV inspection, ensuring CCTV crews spend their time where it delivers the most value.

 Agile deployment

SewerBall inspects miles of sewer network in the time other technologies cover only tens of feet. This free-floating device is quick, cost-effective, and safe to implement; no need for staff to physically enter the network. Inspections can be performed while the system remains in service.

This rapid, drop‑and‑go deployment allows utilities to screen entire basins, prioritize problem areas, and direct CCTV to the highest‑value locations — accelerating decision‑making and reducing wasted inspection time.

 

Adaptable Across Environments

SewerBall works across free-flow sewer systems, with as little as 1.5 inches of water present in the pipe. It can detect many types of disturbances and be deployed in areas with access challenges.

 

Smart Interface

Data is interpreted using our patented AI algorithm. Results are displayed through dynamic maps and graphs, with automatic report generation for fast field decision-making and operational clarity.

Advanced data analysis and asset insights with Sewerball technology 

SewerBall empowers utilities with detailed insight into effluent quality, discharge impact, and underground asset condition. It detects abnormal water intrusions, maps disturbances, and delivers clear and actionable diagnostics. 

This real‑time intelligence helps utilities pinpoint problem areas early, prevent failures, and extend asset life — transforming raw data into operational clarity and cost‑saving insight.

Data Integrity

SewerBall delivers reliable data enabling targeted decisions to maintain underground collection system assets. It generates data clearly indicating clear water, industrial discharge, and saline intrusions.

 

Asset Visibility

Gain deeper knowledge of inaccessible and non-visitable collectors. SewerBall delivers preliminary diagnostics of clear water infiltration zones and maps all types of network disturbances to enhance asset visibility and inform investment planning.

Actionable Data for Smarter Sewer Management

SewerBall transforms raw data into operational intelligence. With real-time diagnostics and automated reporting, utilities can prioritize maintenance, reduce costs, and plan future investments with clarity and confidence.

 

By working ahead of CCTV and identifying where detailed inspection is truly needed, SewerBall strengthens the entire inspection program, reducing unnecessary CCTV runs and improving overall outcomes.

SewerBall enables utilities to:

  • Identify and localize network anomalies
  • Focus maintenance where it matters most to extend asset life and reduce unnecessary repairs
  • Prevent system overloads and environmental discharge
  • Optimize infrastructure investments based on real-time insights
