Common Questions about Water Quality Monitoring

What is water quality monitoring?

What is water quality monitoring?

Water quality monitoring is regularly gathering important parameters related to a building water system, such as disinfectant levels, temperature, pressure, pH, and conductivity.

Why monitor my water?

Why monitor my water?

Proper water quality monitoring generates data that not only increases defensibility but also incorporates verification (initial and ongoing confirmation that the program is being implemented as designed). Water quality monitoring helps to ensure the proper balance between water safety and water efficiency.  Additionally, per ASHRAE Standard 188, proper documentation and verification are crucial. Monitoring allows for a proactive response when limits are not met or exceeded.

At what frequency should I monitor my water?

At what frequency should I monitor my water?

The frequency of monitoring is defined by the Water Management Team (WMT) and may change over time, based upon program data and performance. Considerations for the decision are the situation, facility size, historical evidence of water quality and system operation.


What’s the right combination of Legionella testing and water quality monitoring?

A combination of both periodic Legionella testing (validation) and continuous water quality monitoring (verification), allows the WMT to make better informed decisions that drive validation and verification. An effective combination of the two optimizes the cost of the water system and enhances safety and efficiency.


Where in my facility should I be monitoring?

The water quality parameters can vary based on the monitoring location in the facility. The WMT may also choose to monitor areas of the facility with higher risk factors or implement specific measures based upon the Water Management Program's validation and verification data.


Can I use my existing monitoring equipment?

Yes, a Phigenics Diagnostic Exchange (PDX) can integrate with existing water quality monitoring equipment; data can be sent to phiAnalytics®. phiAnalytics is a cloud-based information management system which empowers Water Management Teams to collaborate, document, verify and validate.


What are the benefits of installing monitoring equipment?

The benefits include: proactive response vs. reactive approach, access to defensible data, increased efficiency and decreased labor associated with water quality monitoring (automatic real-time vs. repeated manual checks).


What parameters can be monitored?

The key is selecting meaningful water quality parameters that provide value at your facility. All monitoring equipment can be customized to accommodate the data stream unique to your water systems:

  • Residual Oxidant
  • Turbidity
  • Temperature
  • Pressure
  • pH
  • Conductivity
  • Many others

What are the benefits of turnkey Phigenics monitoring equipment?

The Phigenics Water Analytics (PWA) is a fully integrated system that is panel or skid-mounted with pre-wired and pre-plumbed configurations enabling turnkey installations.
