Data Analysis & Reporting

Validated flow, depth and rainfall data turned into reports that show where the problems are and what to fix first.

Data is only valuable if it leads to a decision. We validate what we collect and turn it into clear reports for planning, investment and compliance.

Our data validation is ISO compliant. Readings are checked continuously. Where it matters, anomalies are cross-checked against SCADA pump station records and field inspections.

In our experience, about 20% of a sewer network typically carries 80% of its I&I. Good analysis finds that 20%, so repairs go where they pay back.

What we deliver

Continuous QA/QCData validated as it arrives, with calibration checks and remote telemetry throughout the program.
Rainfall-dependent I&I analysisInflow separated from infiltration using on-site rain gauges and historical climate data.
Prioritised repair plansSubcatchments ranked by contribution, with cost-benefit analysis and a staged program of works.
Asset condition insightsShifts in the depth-to-velocity relationship that point to blockages, sediment and structural defects.
Cross connection detectionDry weather flow signatures that reveal illegal discharges and stormwater tied into the sewer.

Results from the field

24 h until flows were back at baseline after relining

After cleaning and relining, our flow profiles showed the network back to baseline within a day, confirming full capacity was restored.

Coastal network
30% less spent on unnecessary relining

Reliable flow data mapped inflow severity across catchments. CCTV inspections and rehabilitation budgets went where they were needed, and compliance targets came sooner.

How the analysis is done

Every calculated figure in EDS FlowSense shows how it was worked out: the method, the constants and the assumptions, in plain language.

  • Dry weather flow

    Sanitary flow and groundwater infiltration separated from qualifying dry days only, with a daily pattern for each type of day.

  • Every storm on its own

    Isolated storms detected automatically, each with its peak, volume, lag and rise above dry weather flow.

  • A split that adds up

    Sanitary flow, groundwater infiltration and rainfall-derived inflow add up exactly to the metered total.

  • Priced at your rates

    Unwanted water costed at your own treatment and pumping rates, and repair options ranked by NPV, benefit-cost ratio and cost per kilolitre removed.

  • The measured record is kept

    Data is checked for flatlines, spikes, drift and impossible values. Repairs are for export only: a gap fill never overwrites what was measured.

  • Catchments that close

    Upstream and downstream sites compared, aligned on travel time, to show where flow is gained or lost.
