Begin updating your water management program today
In our previous entries, we touched on the basics of the ASHRAE Standard 188-2015, why it’s important, and what buildings and facilities are impacted. Now, we’ll take a look at what you should do to follow the published guideline.
Establishing a water treatment program
Most cases of Legionellosis are the result of exposure to Legionella bacteria associated with building water systems, so the standard requires use of a water management program to reduce the risk of Legionellosis associated with those systems.
The water treatment framework within the standard includes these components:
What should I do with the written plan and program compliance information?
Simply keep the documentation and make it available for review as needed by the party or parties responsible for enforcing the requirements of ASHRAE Standard 188-2015.
AS Filtration’s Legionella Risk Management Solutions
Your water management program must include disinfectant to kill or inactivate pathogens, as well as water treatment products to control microbiological activity, scale, and corrosion.
The Aqua-Stream filtration system has been proven to kill and control waterborne bacteria while removing suspended particles as small as 0.5 micrometers (microns).
Pathex® antimicrobial filter media removes particles and controls waterborne bacteria. It’s included in our Aqua-Stream filtration system and is also a drop-in replacement for most sand and multi-media filters. Unlike plain sand filters that often harbor bacteria, Pathex kills waterborne bacteria on contact. Pathex is EPA registered as a pesticide under FIFRA sec 3(c)(7)(A) and is certified by NSF International to NSF/ANSI Standard 61 for drinking water system components.

Most cases of Legionellosis are the result of exposure to Legionella bacteria associated with building water systems, so the standard requires use of a water management program to reduce the risk of Legionellosis associated with those systems.
The water treatment framework within the standard includes these components:
- Program team identification
Indicate who is responsible for implementing and monitoring the water management program.
- Description and analysis of building water systems
Indicate the location and flow of water systems, then identify those that pose the most significant risk for Legionellosis and note where water treatment can be applied.
- Control measures
This is the heart of the standard. Choose and install water treatment measures to effectively reduce the risk of Legionella. Document all treatment measures taken, their implementation schedules and processes, measurement parameters, and corrective actions for each control measure.
- Verification and validation
Outline specific, scheduled reviews of water treatment program documentation and processes to ensure the program is being implemented. Then, perform periodic water sampling of building water systems to validate the efficacy of your treatment measures. Routine testing specifically for Legionellosis is the most direct method for confirming the effectiveness of your program.
