Environmental Data Services (EDS) is an Australian owned and operated company, founded in Queensland in 1991 by Graham and Cynthia Harper. We’ve been a market leader in equipment and services for the water and wastewater industry ever since.
We supply instruments and specialised services to the water and wastewater industry, and to mining, manufacturing, power and processing. Our team is scientists, engineers and technicians who are good at every part of environmental monitoring, from the manhole to the final report.
Our purpose is simple: to give you the data and the confidence to take control of your assets and projects. We like finding things out, and we build the technology and the services that make it possible.
Our mission
We’re committed to the best equipment and service we can deliver, judged by one thing: whether it got you the outcome you needed. Innovation, sustainability and a genuine curiosity about how networks behave are what drive us.
We give businesses and organisations the tools and the insight to make informed environmental decisions, and a more sustainable future comes with them.
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.
EDS makes instruments, represents leading manufacturers, installs and maintains them with our own crews, and delivers the data. One team answers for the whole chain, so there’s never anyone else to call.
Manufacturer and representative
EDS designs and builds its own loggers and sensors, and represents leading manufacturers including Detectronic, ORI, Hach and Beadedstream.
Our own field crews
Installation engineers 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 sewer environments.
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.
