Surface & Groundwater Monitoring Solutions

Surface water can be affected by land use, agricultural practices, pollution and climate change. As you already know, monitoring and treatment of surface water requires significant investments in time and money. These investments and public health may be jeopardized if surface water changes during extreme events or contamination.

Sensors and systems from Xylem brands, YSI and SonTek, work to provide a continuous and comprehensive record of water quantity and quality. From a simple handheld dissolved oxygen meter to a solar powered remote monitoring station our instruments provide the reliable data you need to act quickly work efficiently and reduce costs.

We understand the challenges of working in natural environments. Our specialists have decades of experience with water quality applications such as discharge consent, diffuse pollution monitoring, storm water, dredging, construction compliance as well as flood alert monitoring, river gauging and flow using ADCP. We can help you design your monitoring programme including feedback on site selection, calibration frequency and recommended parameters.

Low power availability, biofouling, alarms and remote viewing of data are all issues which can be solved using our innovative solutions. Continuous monitoring helps you to better understand your water course allowing you to detect events, make real-time decisions and manage your site.

Our systems play a key role in improving water quality and plant efficiency, while allowing for early warning and rapid response to events such as floods and algal blooms.
