For rivers and streams we offer a range of impeller and electromagnetic current flow meters to use as a point velocity measuring devices to aid monitoring during catchment management, discharges and pollution.
Water level can be monitored via pressure transducer and logger together with radio and GSM/GPRS telemetry options.

Hydroelectric dams produce electric power by harnessing the force of the water flowing through the dam. There are numerous sources for oil spillage:
- The hydroelectric turbines are lubricated by lubrication oils.
- The very large water control valves are normally hydraulic powered and are lubricated with various greases and oils.
- Vehicles including fork lifts, trucks, etc., can spill oils and fuels.
Any accidental spillage of oil or grease or intentional wash down water containing minor amounts of oils, greases, and detergents must be collected and treated before discharge to the river. These fluids along with any water leaks are collected in sumps in the dam and are regularly pumped out. In many cases, the volume of water is substantial.

Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points as it gradually makes its way from its source to our oceans. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality. Control of water pollution was once concerned mainly with treating wastewater before it was discharged from a manufacturing facility into the nation`s waterways. Today, in many cases, there are restrictions on wastewater that is discharged to city sewer systems or to other publicly owned treatment facilities. Many jurisdictions even restrict or regulate the runoff of stormwater — affecting not only industrial and commercial land, but also residential properties as well.
