Asset & Network Assessment

Catch blockages, structural defects and cross connections early, and see where to spend first.

A deteriorating network rarely fails all at once. Long before anything fails outright, it starts costing more to run, in staff time and maintenance.

Regular assessments from EDS catch that slide early and keep your network performing at its best.

Accurate flow data shows far more than inflow. At one regional council, a sudden shift between depth and velocity revealed a partial blockage in a rising main, and CCTV confirmed the debris.

Illustration: a site’s depth against its velocity. Readings that leave the usual relationship can point to a blockage, sediment or a structural defect, before anything fails outright.

What we look for

Blockages and sedimentA steady rise in depth with no rain to explain it, found and cleared before the next storm.
Structural defectsDepth anomalies that point to sags, displaced joints and infiltration points.
Cross connectionsOvernight flow in dry weather, or a rainfall response a residential catchment shouldn’t have.
Where to spendInflow severity mapped across catchments, so inspections and rehabilitation go where they’re needed.

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.

All results

How we assess

  • Flow and depth monitoring at hydraulically sound sites
  • Temperature studies to locate where water enters
  • Level alarms on lines at risk of blockage or overflow
  • Validated analysis, and a report with priorities and costs
  • Monitoring repeated after the works, to confirm the result
