A Look Inside Our Remote Monitoring Network

Once a well is operational, its behaviour becomes as important as its initial yield. Changes in water level, flow or pump performance can affect service and cost. Remote monitoring brings these observations together so operators can respond with better information.

Waterfinders Solutions offers remote monitoring and control, performance dashboards and periodic analysis. The example below explains a typical system architecture. It does not depict a specific customer installation or live operating data. [1]

Begin with the right measurements

A monitoring specification should start with the decisions the operator needs to make. Water level helps track drawdown and recovery. A flow meter records delivery and abstraction volume. Pressure, pump status and energy consumption help place changing performance in context. The value lies in reading these measurements together.

Water quality needs a defined scope

Depending on the installation, sensors may measure temperature, electrical conductivity, pH or other selected parameters. Reliable records require suitable instruments, cleaning, calibration and data review. The equipment and maintenance plan must match the groundwater environment. [2]

A conductivity change can flag a change in dissolved-ion content, but it does not identify every contaminant. Routine sensors do not establish the absence of PFAS, pesticides or pathogens. Sampling and laboratory analysis remain necessary for parameters outside the installed sensors’ validated capabilities.

From the well to the operator

A local logger collects timestamped readings and passes them through the selected communications link. The design should account for power supply, signal coverage and loss of connectivity. Local storage can preserve readings during an outage if that function is specified. The display should distinguish a current reading from an old or missing one.

Make alerts actionable

Thresholds should reflect commissioning results, operating limits and seasonal behaviour. A sustained level decline at comparable pumping rates merits a different response from a brief change when a pump starts. Missing telemetry should generate a data-status alert, so an offline device is not mistaken for a healthy well.

Consider an illustrative case: delivered flow falls while energy use remains elevated. The operator checks sensor validity, pump settings, water level, pressure and recent maintenance. Possible explanations include greater pumping lift, an obstruction or pump wear. The observations guide investigation; one trend alone does not establish the cause.

Monitoring and control are separate functions

Displaying readings does not require permission to start or stop a pump. Where remote control is included, the design should define authorised users, local interlocks, communication-loss behaviour and an audit trail. Protective functions must remain appropriate to the installation even when a remote display is unavailable.

Turn records into better operation

Regular review can compare abstraction, drawdown, delivered volume, energy use, alarms and maintenance history. Comparing equivalent operating conditions makes trends more useful. WFS can discuss monitoring objectives and the scope of a suitable installation; actual sensors, reporting frequency, control functions and response responsibilities should be agreed for each project.
