We provide specialist, yet cost-effective solutions to your groundwater monitoring issues. Our range of dedicated down-well bladder pumps eliminates the possibility of cross-contamination and sample inaccuracy.

With the Well Wizard range, you can improve efficiency by increasing the accuracy of your data, while decreasing the time it takes to collect it.

Conventional monitoring systems may involve bailing, well purging, or high-rate pumping. These procedures can mix stagnant water from the upper, unscreened portion into the sampling zone, or agitate the well and surrounding aquifer. The result - less accurate data.

The Well Wizard's gentle air-driven bladder pumps provide you with more accurate data in less time. Its dedicated low-flow setup will collect representative samples without disturbing the rest of the well or the surrounding formation.

Add the Micropurge Pump Controller, Water Level Meter, or Flow Cell/Analyser, and you have a system that improves sample quality and cuts costs.

On the farm, we provide the ‘SAFE’ stop-go valve, a unique 'set and forget’ solution to dairy effluent issues in a cost-effective and easy-to-install package.
