Public Review Opens for Manual on Construction Practices for Potable Building Water Systems

IAPMO has opened a 45-day public review period for a revised draft of its Manual of Recommended Practice: Construction Practices for Potable Building Water Systems, inviting industry stakeholders to review and comment.

The updated draft reflects ongoing refinement informed by industry experience, emerging research and stakeholder input. The manual provides guidance for managing potable building water systems during new construction, renovations, expansions and commissioning, helping protect water quality before buildings are occupied.

The document addresses key construction-phase activities that can impact water quality, including preconstruction planning, construction practices, flushing protocols, water quality monitoring and preoccupancy disinfection. It is intended for plumbers, contractors, engineers, building owners, inspectors, public health professionals and authorities having jurisdiction.

The public review period will remain open through April 24. The draft document and instructions for submitting comments are available here.
