Building Water System Guidance Analysis

Building water system flushing and recommissioning protocols are being rapidly developed by multiple organizations. This page provides resources for building owners, public health officials, and private sector organizations who are seeking to develop, analyze, and improve their protocol documents.

The evaluation tool below was created based on a recent paper, "Considerations for Large Building Water Quality after Extended Stagnation" co-authored by 9 plumbing, water quality, and public health experts and conversations with various public health and environmental quality public servants.

More information and resources will be posted in the coming days.
