The U.S. Centers for Disease Control and Prevention (CDC) has issued guidance to ensure the safety of building water systems and devices after a prolonged shutdown. ACWA encourages member agencies to review the CDC’s “Guidance for Building Water Systems” and share the information with customers, such as schools, businesses and office buildings that have been unoccupied during the state’s stay-at-home order and are preparing to reopen.
Stagnant or standing water can cause conditions that increase the risk for growth and spread of Legionella and other biofilm-associated bacteria. The CDC guidance includes a toolkit designed to help people understand which buildings and devices need a Legionella water management program to reduce the risk of Legionnaires’ disease.
The guidance also includes eight steps for customers to take, including flushing water lines, to ensure the water system is safe to use.
