Water management planning to prevent Legionnaires’ disease

Proper water system maintenance is essential for controlling growth of Legionella, the bacteria that causes Legionnaires’ disease. Developing a water management program is an important first step for making sure that your building’s occupants and neighbors are safe from infection.

The Department of Public Health has created several tools to help building owners and operators develop water management programs that are specific to their facilities.

If you would like more information about developing a water management program, call the Acute Communicable Disease Program at (215) 685-6742.
