In order to provide the highest quality of health care to our nation s veterans, and to protect the health and safety of patients, visitors, and employees the potable water distribution system is treated with Chlorine Dioxide in accordance with VHA Directive 1061. (A continuously operating Chlorine Dioxide water disinfection system serves as the primary source of Legionella mitigation and to control other bacteria, viruses, and protozoa.) In addition to a comprehensive maintenance schedule and testing, SLCVAMC employees also perform continuous testing at system outlets for Legionella. Through a dual redundant chlorine dioxide generator system, an average of 75,000 gallons of water a day is treated on campus. Check valves, sensors, and other safeties monitor chemical tank levels, air quality, and chemical concentration in treated water. Any deviation outside of the parameters will alarm to the campus boiler plant which is continuously manned. Period of Performance: Period of performance will be from date of award through one year. Within 30 days of contract award, the Contractor shall initiate communication with the COR to establish quarterly dates for the maintenance schedule and contact information for SLCVAMC staff associated with the contract.
