Water System Monitoring and Sampling

One of the most important duties of a water operator is record keeping. It allows you to identify quickly whether there is a problem with your system somewhere and fix it until there are any risks to human health.

Some key aspects of water monitoring:

  • Daily inspection of your water supply ensures safe drinking water at all times
  • Helping to find issues early so you can easily and effectively take action
  • Ensuring that the treatment system operates accordingly
  • Provides information on your water supply, including water quality improvements

You can easily recognize changes and be ready to take action by being familiar with the normal operating parameters of your system.


The purpose of the sampling is to gather a representative amount of water to be checked for different characteristics or criteria that provide data on the safety and operation of your water supply.

Sampling is an in-time snapshot. Tomorrow, the parameters seen in today's sample might change, so sampling must be performed periodically. Sampling is also used to test for bacterias like legionella.

A different type of bottle or jar may be used, depending on the parameters being sampled, and often a special preservative is applied to the jar before sampling. An analytical testing laboratory will supply the necessary containers and advise on how to use them.

Temperature Monitoring

When it comes to a source of drinking water that can be safely used by humans, its temperature plays a very important role and must be monitored very carefully.

Drinking water temperature must be maintained within a specific range. Any temperature above or below that range can create an environment for bacteria to grow and endanger the safety of human life that interacts with that water supply.

One common bacterium that the United Kingdom is struggling with is Legionella, which grows best within a certain temperature range (25°C - 42°C)

One easy way to keep track of your water system temperature is with our water temperature sensors. You can read more about them here.
