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.
Manuals for developers building water mains
Developers who are building water mains as part of new construction or subdivision development need to use the following two manuals:
The Developer's Manual provides information about the design and construction of water systems built by developers.
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.

Vaults CAD drawings
Vault drawings include differences in installation settings, vault sizes, and b and c options for some, where the piping has alternatives that may be needed due to the setting.
All vault drawings are intended to be used with P-855 General Vault Details and should not exclude P-855. Use of vault drawings with a c in the number indicates they are not preferred and may require approval before use.
