Information
If you're applying for a building permit, a public works permit, or a utility permit, or if you interact with the water system in the right-of-way, use these manuals and CAD standards to understand the potable water design and construction requirements.
Utility protection guidelines
The guidelines in the utility protection plan are intended for the use of developers, contractors, and other utilities when working in and around Portland Water Bureau water facilities, including excavation in the public right-of-way.
Materials Manual
The Materials Manual provides technical and general product specifications, and lists products that have been reviewed and prequalified for use in the Portland water system for pressures of up to 150 psi (1034 kPa) unless otherwise stated. All other pressures will be outlined in specific project specifications. Project specifications may supersede products presented in the Materials Manual.
Standard drawings
All Portland Water Bureau standard drawings (P-700 through P-1000) are posted on the Citywide list of Standard Drawings and Details.
