Question 1

Is ASHRAE 188 required for apartment buildings?

Accepted Answer

ASHRAE 188 applies to buildings with centralized hot water systems, cooling towers, or decorative fountains — which includes many multifamily apartment buildings. Even where not legally mandated, maintaining a Water Management Plan (WMP) significantly reduces Legionella liability exposure for property owners and managers.

Question 2

What is a Water Management Plan?

Accepted Answer

A Water Management Plan (WMP) is a documented program required by ASHRAE Standard 188 to prevent Legionella growth in building water systems. It identifies hazards, establishes control measures, and defines monitoring protocols for your facility's water systems.

Question 3

Who needs a Legionella risk assessment?

Accepted Answer

Any building with a centralized hot water system, cooling tower, decorative water feature, or occupants at heightened risk (elderly, immunocompromised) should have a Legionella risk assessment. This includes hospitals, hotels, apartment buildings, schools, and office buildings.

Question 4

What is ASSE 12080 certification?

Accepted Answer

ASSE 12080 is an American Society of Sanitary Engineering standard that establishes competency requirements for individuals managing building water safety programs. It is widely referenced alongside ASHRAE 188 as the standard for Water Management Team qualification.
