Sewer Flow Monitoring

Temporary and permanent flow monitoring for councils and water authorities, installed by trained crews Australia wide.

EDS provides comprehensive sewer flow monitoring to help councils and water authorities manage their wastewater infrastructure efficiently and effectively. With more than three decades of experience, we pair industry-leading technology with hands-on support to deliver accurate, reliable data for informed decisions.

Our crews are highly trained installation engineers, available Australia wide, who deliver results that are both safe and accurate. And unlike other providers, EDS gives you full access to the data.

Why choose EDS

Precision and reliabilityOur fleet features the latest Detectronic MSFM area velocity flow meters, intrinsically safe and certified under ATEX and IECEx.
Expertise you can trustField crews complete rigorous training in installation, maintenance and calibration, so every unit is installed correctly.
Flexible programsFrom short-term inflow and infiltration studies to long-term monitoring that supports sewer master planning.
Advanced sensorsIncluding the LIDoTT level sensor for highly precise measurement across changing conditions.
Customer-focusedWe stay with you through data collection and interpretation, not just the install.

What is included

Temporary and permanent flow monitoringIdeal for I/I studies, model calibrations and compliance reporting.
Comprehensive data analysisDetailed insights in reports that are easy to interpret, supporting planning and regulatory compliance.
Custom installation and site inspectionsProper hydraulic site selection and installation to guarantee accurate data.
Rainfall correlation studiesData from RIMCO 7499 tipping bucket rain gauges shows how rainfall events affect the network.
Seamless data integrationData is transmitted directly to our platform, with API options for your existing systems.

Applications

  • Sewer model calibration to support long-term planning
  • Identifying sources of inflow and infiltration to reduce treatment costs
  • Capacity assessment for future infrastructure expansion
  • Compliance with environmental regulations
  • Early detection of blockages and potential system failures

Results from the field

$6M treatment plant expansion avoided

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.

How a program runs

From the first call to data you can act on.

  1. 01

    Scope and site selection

    Agree what the data has to answer, then choose sites by their hydraulics, not their convenience.

  2. 02

    Install and commission

    Trained EDS crews install intrinsically safe instruments, Australia wide, and check every site before it goes live.

  3. 03

    Monitor and validate

    Readings arrive over 4G into FlowSense, with continuous QA/QC and alarms when something changes.

  4. 04

    Report and recommend

    Validated data and a report that shows where the problems are and what to fix first, or a feed into your model by API.

Try it

What the flow meter sees in a storm.

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.

An illustrative model of a 600 mm sewer, not live data. Flow is wetted area multiplied by velocity, the way an area-velocity flow meter measures it.
