22 DEVELOPING A LEGIONELLA WATER MANAGEMENT PROGRAM 7 Document & Communicate All the Activities of Your Water Management Program Documentation Now that you have done all of the work required to create your water management program, write it down. Your written program should include at least the following: 6 6 6 6 6 6 Program team, including names, titles, contact information, and roles on the team Building description, including location, age, uses, and occupants and visitors Water system description, including general summary, uses of water, aerosol-generating devices (e.g., hot tubs, decorative fountains, cooling towers), and process flow diagrams Control measures, including points in the system where critical limits can be monitored and where control can be applied Confirmatory procedures, including verification steps to show that the program is being followed as written and validation to show that the program is effective Document collection and transport methods and which lab will perform the testing if environmental testing is conducted Communication You have worked hard to develop your water management program and you have carefully documented all aspects of it. Resist the temptation to put it on a shelf and walk away. Consider notifying building occupants that you have a plan in place to keep the building water systems safe, just as you would for an elevator inspection. Be sure to communicate with your employees and colleagues about your program on a regular basis and train those responsible for implementing and monitoring the program. Use this communication as an opportunity to identify strategies for improving the management and efficiency of your water systems.
