Purpose

Veteran's Health Administration (VHA) Policy establishes guidelines for the prevention and control of healthcare-associated Legionella disease in

VHA buildings.

The efficacy of biocides on suppressing or killing waterborne pathogens is dependent on multiple factors such as water quality, organic and inorganic contaminants, pH levels, disinfectant concentrations, and contact time. Water entering the building shall be continuously monitored for the following by means of gauges, sensors, and a grab sample port:

Temperature, Oxidant level (water disinfectant), pH, and Pressure

Water systems within the building shall be monitored as follows in the table below. Temperature and oxidant levels are the two primary engineering controls to limit bacterial growth. Oxidant levels shall be measured continuously as water enters the building and through grab samples taken from building plumbing fixtures. Temperature shall be measured throughout the domestic water system (hot and cold). In addition to being a primary control measure, temperature can be a secondary indicator of flow since temperature of stagnant water will lower for hot water and rise for cold water.

Background

Legionella is a bacterium that causes respiratory diseases collectively referred to as Legionellosis that includes Legionella pneumonia. Legionella pneumonia is also known as Legionnaires Disease (LD). Legionella bacteria are found naturally in water and have been associated with disease from building water distribution systems. LD occurs after inhalation or aspiration of contaminated water. Legionella bacteria are not transmitted from person to person. The elderly and persons with immune compromised systems are most at risk. Legionella bacteria growth increases in tepid water in a range from 20 deg C [68 deg F] to 50 deg C [123 deg F].

Given the various factors and complexities associated with LD, 100% prevention of LD is likely not possible. However, prevention and control practices can be implemented to reduce the risk of exposing people to Legionella in building water distribution systems. The following are engineering controls that will suppress Legionella growth. More than one control may be necessary for successful inhibition of Legionella growth.

(a) Temperature

· Maintenance of appropriate water temperatures is required. Water above 51.1 deg. C [124 deg. F] inhibits growth of Legionella in hot water systems. Precautions for the prevention of scalding shall be included in the hot water distribution system.

· Cold water temperatures below 19.4 deg. C [67 deg. F] inhibit the growth of Legionella.

(a) Flow

· Recirculation of water distribution systems is a means of limiting Legionella growth due to low flow or non-use periods. Recirculation aids in maintaining required water temperatures. Hot and cold water distribution systems shall be continuously circulated and piping insulated.

(a) Oxidant (Disinfectant)

· Maintenance of disinfectant at a sufficient level to control Legionella growth may be required. The minimum level required to suppress bacterial growth will vary from building to building and by the type of oxidant (disinfectant) used. Monitoring of levels is required.

Piping Installation Guidelines for Legionella Mitigation:

· The need to chill or cool the domestic cold water supply shall be evaluated at the schematic phase. Legionella can propagate in temperatures exceeding 20 deg C [67 deg F]. The domestic cold water distribution system shall have a recirculation system. For cold water systems, although circulation back to the source location for the building is ideal, for renovation efforts, recirculation within the department (or floor) area of renovation would be acceptable.

· Ice maker water supply lines shall be copper and insulated. Avoid routing water lines near source of heat such as the compressor system of the ice maker.

· Cold and hot water piping systems shall be insulated in accordance with the latest version of ASHRAE 90.1.

· To enable thermal eradication and emergency shock chlorination, consider providing taps for connection of temporary booster heaters. Provide adequate electrical connections.

· PVC pipe shall not be used for sanitary and vent lines because of the high temperature water during thermal eradication. Cast iron shall be used.

· Aerators are prohibited in order to reduce exposure to Legionella contaminated water.

· Piping materials shall be in accordance with VA Master Spec 22 11 00 Facility Water Distribution.

· Piping and components must be cleaned and protected from accumulation of debris and contamination prior to and during installation.

· Ensure that newly installed piping and components are flushed of debris and disinfected prior to being placed into service.

Supplemental Water Disinfection Methods

In addition to maintaining the appropriate water temperatures, minimum concentrations of various biocides (e.g. oxidizing agents such as chlorine) can inhibit the growth of Legionella in building potable water distribution systems. When considering the use of supplemental water disinfection methods for the prevention of Legionella, plumbing designers and the VA project manager (in collaboration with other facility stakeholders such as infectious diseases and infection prevention and control) shall review the merits of the many types of supplemental systems available prior to making a final selection. VHA recognizes United States (U.S.) Environmental Protection Agency (EPA) approved oxidants

(chlorine, monochloramine, and chlorine dioxide) as acceptable disinfectants for use in potable water distribution systems.

Selection of the necessary equipment, piping and controls and adequate space for the maintenance and operations, are a must. The EPA regulates contaminant levels and disinfectant treatment for use under the Safe Drinking Water Act. Usually, the EPA delegates primacy to States for the regulation and enforcement of the Act within individual State boundaries. Systems must be specifically approved or recognized for the intended use by the State regulatory water authority. Federal and state safety regulations and permitting shall be followed. Designers shall coordinate permitting requirements with the local authority having jurisdiction. The facility must consult with the State (or its delegated local water authority) for regulating drinking water for guidance on system selection, achieving an appropriate biocide residual level at building outlets for

Legionella growth suppression, system design, system operation, and ensuring compliance with regulations regarding water treatment system(s) and safety. Once a type of system is selected, either the State (or its delegated local water authority) or the manufacturer of the system must provide the minimum and maximum outlet biocide levels in writing for both hot and cold water.

Design parameters to evaluate for supplemental water disinfection include:

· Potential impact of supplemental disinfectant on special use water systems.

· Need for emergency power.

· System may need to be duplex for redundancy and maintenance.

· Spare parts may need to be purchased and stored locally.

· Federal and state safety regulations and permitting must be observed.

· Interaction of supplemental disinfection if shock chlorination is used as an emergency remediation method.

· Ensure enough maintenance access is provided around equipment.

· Provide sample points throughout the system to monitor effectiveness. Some critical points should be provided with automated data collection and alarm.

· Operational and maintenance requirements must be maintained to ensure system effectiveness.

· System must be equipped with automated features to ease of use and proper maintenance and operation.

· Requirements for off gassing associated with the specific chemicals (for example Sodium hypochlorite).

· Chemical spill containment systems must be provided.

· Chemical storage requirements.

Emergency Water Disinfection Methods

Emergency disinfection is the process of implementing immediate, temporary actions to reduce the amount of Legionella in a water distribution system.

Thermal Eradication

Requires potable water in the system to be raised to 71 - 77 deg C [160 - 170 deg F] and flushed through every fixture for 30 minutes. Some design considerations are as follows:

· Central water heating equipment must be capable of raising water temperature to 82 deg C [180 deg F].

· Master thermostatic mixing valve located in the hot water distribution system may have to be bypassed to allow hot water to circulate in the distribution system.

· Select point-of-use thermostatic mixing valves that are amenable to thermal eradication procedures. See VA Master Specification 22 05 23 for required mixing valves.

· Provide taps for a connection of temporary booster heater to facilitate thermal eradication.

· Provide adequate electrical connections for temporary booster heaters. Coordinate with electrical engineer.

· All equipment and appurtenances in the system will need to be reviewed for operation at elevated temperature (e.g. ensure water supply stops can withstand required temperatures).

· Means of tempering discharge will need to be considered to accommodate code requirements on discharge to sanitary sewer (max temp of

60 deg C [140 deg F]). Ensure discharge is compliant with the local requirements.

Shock Chlorination

Installation of a chlorinator is required. Shock chlorination involves the addition of chlorine to the water system in one of the forms listed above.

Some design considerations are as follows:

· Provide taps for connection of temporary equipment.

· All equipment and appurtenances in the system will need to be reviewed for operation at elevated oxidant levels.

Special Use Water Systems (e.g., hemodialysis, laboratory, pharmacy compounding) It is important to consider the implications of Legionella mitigation strategies on special use water systems within the building. Special use water systems include: Hemodialysis, Laboratory Service, Pharmacy Compounding, and Supply Process Service (SPS). Water treatment strategies and chemical disinfectants may result in the introduction of products into, or the formation of disinfection byproducts in, the building water supply at concentrations that may be toxic to patients on hemodialysis. Accordingly, the impact of mitigation strategies must account for potential toxicity, methods for removal of the chemical agent and byproducts from the special use water system, and availability of assay methods to measure the chemical agent and byproducts for assuring patient safety. VA authorities responsible for the oversight of special use water systems are to be consulted during design development of the project and prior to any final decisions regarding water treatment strategies for Legionella.

INSPECTIONS AND WITNESS OF TESTS

The inspection plan needs the approval of the project technical COR. Frequency and requirements for inspections and testing must be added to the construction documents. Regarding inspections and test witnessing, the plumbing drawings and specifications shall coordinate with the VA

Manual on Systems Commissioning and the project's commissioning specifications.

Ensure that newly installed piping and distribution system components are flushed of debris and disinfected prior to being placed into service.

Piping and components must be cleaned and protected from accumulation of debris and contamination prior to and during installation.

Documentation of flushing and disinfection must be maintained. Disinfection for new installations or maintenance of piping, equipment, and components shall be conducted in accordance with the requirements of the IPC, American Water Works Association (AWWA C651-05), and VA

Master Construction Specifications.

WATER DISTRIBUTION SYSTEMS

Water Storage Tanks: Provide adequate space for maintenance access to clean the interior of all water storage tanks. Tanks shall be provided with a man way access to allow for inspection, maintenance and cleaning. Tanks shall be constructed to minimize stagnation and thermal gradients. Mechanical cooling may be needed to maintain water temperature.

Measuring and Indicating Devices

Analog gauge and electronic sensors/devices shall be used in tandem as much as is practicable. The gauge device will provide a local or immediate indicator of current conditions for troubleshooting and verification purposes. The electronic sensor/device will be used for continuous monitoring of water conditions and shall be connected to the building automation system. All electrical devices shall be on emergency power. All measuring devices shall be calibrated in accordance with the manufacturer's recommendations.

Domestic Cold Water Sequence of Operation (See schematic detail CA and service detail B4)

Water will flow as required for fixture use. Water temperature will be measured at a minimum of three locations:

CT-1 at the meter; CT-2 on the return pipe; CT-3 near the midpoint of piping, and CT-4 at main tap in the rehab building basement.

Once all fixture use has stopped as measured by flow meter CF-1, the flow meter will send a signal to the Domestic Cold Water Pump to start. Pump will circulate domestic cold water until flow meter CF-1 senses fixture usage and pump will stop.

Water pressure will be monitored at 3 locations, before and after meter/RPZ and at suction size of return pump.

Water quality shall be monitored before meter, CQ-1.

Domestic Hot Water Sequence of Operation

(SEE SCHEMATIC D4)

Water will flow as required for fixture use. Water temperature will be measured at a minimum of four locations:

HT-1 near the water heating source; HT-2 after mixing valve; and HT-3 near the middle of the domestic hot water piping; and HT-4 at the farthest point from the heating source. Domestic hot water piping will be looped to feed all fixtures before returning back to the water heating source.

Domestic Hot Water Return Pump shall circulate hot water continuously (no shut down or aqua senser). Water flow shall be monitored by HF-1. Once flow stops, HF-1 shall send a signal to the Building Control System indicating a flow failure.
