Graham and Cynthia Harper founded Environmental Data Services (EDS) in Queensland in 1991. Today we’re Australia’s largest supplier of monitoring equipment to the water and wastewater industry, and still Australian owned.
We also supply instruments and services to mining, manufacturing, power and processing. Our team covers every part of environmental monitoring, from the manhole to the final report.
Our purpose is simple: to give you data you can trust, and the confidence to act on it. We build the instruments, the platform and the field services that make that possible.
Our mission
We judge our equipment and our service by one thing: did you get the outcome you needed? Behind that is real curiosity about how networks behave, and the engineering to measure them properly.
Good environmental decisions need good data. We give organisations the tools and the insight to make them, and a more sustainable future follows.
In the field
The work, as it is.
Sewers, chambers, cabinets and poles: the sites our crews instrument, visit and keep reporting.





Instruments, crews and data, from one team.
We make instruments, represent leading manufacturers, install and maintain them with our own crews, and deliver the data. One team answers for all of it, so there’s never anyone else to call.
Manufacturer and representative
We design and build our own loggers and sensors, and represent Detectronic, ORI, Hach, Beadedstream and others.
Our own field crews
Engineers and technicians trained in installation, maintenance and calibration, working from four offices and travelling Australia-wide.
Certified for hazardous areas
Intrinsically safe equipment certified under ATEX and IECEx, including Zone 0 instruments for sewers.
Data you can defend
ISO-compliant data validation, with continuous QA/QC and calibration checks throughout every program.
One platform
Readings arrive in EDS FlowSense, built and supported in Australia, or go straight to your own SCADA and systems.
Your data, always
Full access to the data we collect, in open formats, through FlowSense or by API.
