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. EDS validates the data it collects and turns it into reports that are easy to interpret, supporting planning, investment and regulatory compliance.

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

In EDS’s experience, about 20% of a sewer network typically accounts for 80% of its inflow and infiltration. Good analysis finds that 20%, so rehabilitation goes where it pays 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 remediation plansSubcatchments ranked by contribution, with cost benefit analyses and a phased 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.
Full access to your dataThrough FlowSense, or by API into your own systems.

Results from the field

24 h until flows were back at baseline after relining

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.

Coastal network
30% less spent on unnecessary relining

Inflow severity mapped across catchments from reliable flow data sent CCTV inspections and rehabilitation budgets where they were needed, and compliance targets were reached sooner.

All results

From an EDS project

  • Three subcatchments, 65% of the I&I

    A regional council engaged EDS ahead of a treatment plant upgrade. Twenty short term flow meters and on-site rain gauges showed where the water was coming from.

  • A $6M expansion avoided

    The evidence let the council redirect capital into relining, manhole sealing and inflow source reduction.

  • Peak wet weather flows down 35%

    Targeted rehabilitation delivered the reduction within two years.

How the analysis is done

Every derived figure in EDS FlowSense carries a note on how it was calculated: 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 uplift over dry weather flow.

  • A split that adds up

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

  • Priced at your rates

    Extraneous volumes costed at your own treatment and pumping rates, and remediation 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.
