Guidance for Sanitizing Residential Water Treatment Systems

This document provides general guidance and information for water treatment professionals who may be called upon to sanitize drinking water treatment systems used within a home or business environment after a prolonged period of stagnation due to building vacancy, flooding, or similar potential contamination events. For example, this guidance would be appropriate when assisting customers who are bringing recently vacated buildings back online after COVID-19 “Shelter-In-Place” orders are lifted.
