The Institutional Water Treatment program (IWT), part of the Illinois Sustainable Technology Center's Technical Assistance Program, provides unbiased, professional water treatment advice to facilities equipped with institutional water systems such as cooling towers, chillers, and boilers. Their services range from presenting on-site training and seminars to providing chemical specifications and making recommendations for a comprehensive water treatment program to control corrosion, mineral scale formation, and biological growth.  IWT now offers on-site water sample collection and two laboratory test methods for L. pneumophila detection.
