Asset & Network Assessment

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

At a glance

  • Blockages and sedimentFound and cleared before the next storm
  • Structural defectsSags, displaced joints and infiltration points
  • Cross connectionsOvernight flow in dry weather
  • Where to spendInflow severity mapped across catchments

A deteriorating network rarely fails all at once. It costs more to run first, in staff time and maintenance, long before anything fails outright.

Regular, consistent assessments from EDS catch that slide early and keep your network and assets performing at their best.

Accurate flow data reveals far more than inflow. In one regional council, a sudden shift in the depth to velocity relationship revealed a partial obstruction in a rising main, and a targeted CCTV inspection confirmed the debris.

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 should not have.
Where to spendInflow severity mapped across catchments, so inspections and rehabilitation go where they are needed.

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
