Data that changed the decision.
Twenty short term flow meters and on-site rain gauges showed three subcatchments carried 65% of the I&I. Capital went into relining and inflow reduction instead, and peak wet weather flows fell 35% within two years.
Sewer monitoring across the Wulguru and Pallarenda catchments, to inform the council's infrastructure planning and management.
After a cleaning and relining program, flow profiles recorded by EDS showed the network back to its baseline hydraulic behaviour within a day, confirming the works had restored full capacity.
High resolution sewer flow and rainfall monitoring, giving the utility the data it needed for infrastructure planning and management.
Flow lab
See what a storm does to a sewer.
Send a storm through a model catchment and watch the hydrograph respond. The gap between measured flow and the dry weather pattern is inflow and infiltration: water that should never have reached the sewer.

What the data has taught us.
October 2025
The Unforeseen Benefits of Sewer Inflow & Infiltration Monitoring
How modern sewer flow monitoring programs deliver far more than I/I insights. Drawing on real projects across Australia, it shows accurate flow data helping utilities detect blockages, verify maintenance, identify cross connections, optimise pump operations and target investment.

Inflow & Infiltration: Measuring the Invisible Problem
Excess stormwater and groundwater entering sewer systems remains one of the most costly and complex challenges for councils and utilities. With asset pressures rising and budgets under strain, targeting I&I is more critical than ever.
