Water Management Plan Guidance

A water management plan is used to control Legionella within a building’s water systems. Current industry best practices for prevention of Legionellosis and other pertinent information are available on the Legionella Resource Library. Not all of the information outlined below may be applicable to your facility.

If your facility’s staff does not have experience in this area, we recommend contacting a consultant who specializes in the control of Legionella for the development of your water management plan.

Should your facility be associated with a case of Legionellosis, an environmental assessment will be performed by the health district and a water management plan may be requested for review. The plan should contain the following items:

  1. A schematic of the plumbing system indicating how the water is delivered to the various floors.
  2. A floor plan indicating the locations of all water heaters.
  3. A copy of the HACCP Plan used to control Legionella in the building’s water system. The HACCP Plan should include the following information:
    • Potable water systems
      • Maintenance of the system
      • Methods of monitoring of water treatment including location of logs that record the following:
        • hot and cold water temperatures
        • chlorine residuals
      • Routine and emergency disinfection procedures of the water systems
    • Pools and spas
      • Site plan of pools and spas
