Understanding Legionella Management and ASHRAE 188

What Is ASHRAE 188?

            ASHRAE 188 is a standard created in 2015 (and updated in 2018) which outlines the importance of a water management plan for preventing the growth and spread of Legionella, a bacteria that can lead to the potentially life-threatening Legionnaires Disease. The standard suggests that certain facilities like healthcare facilities or overnight facilities (such as hotels) actively treat water for Legionella. While this is an optional standard, many local building codes are requiring facilities to adhere to it and create a new water treatment plan or update an existing one.

Those at Risk

            While a proper water management plan is recommended for any facility with a complex water system, ASHRAE 188 identifies several factors that increase the risk of the spreading Legionellosis, which may lead to stricter enforcement for certain types of facilities. For example, people over the age of 65, as well as people with compromised immune systems are more susceptible to contracting Legionnaires Disease, so healthcare or assisted living facilities are more likely to be required to implement and maintain a water management plan

Creating a Water Treatment/ Management Plan

            A water treatment plan can be difficult to come up with, but in order to remain compliant and safe, one may be necessary for your facility. All water systems are a little different depending on factors such as location, type of application being used, and the age of the system. A water treatment expert is able to analyze a water system and identify what treatment methods will work best to create a lasting, compliant water treatment program. FCT Water also offers continuous customer support and a free system analysis with our management plans.
