2020 Sewer and Drainage Facilities Design Manual

Link to the manual PDFThe Sewer and Drainage Facilities Design Manual (SDFDM) provides information to assist City staff, Consultants, designers and others who are responsible for planning, designing, constructing, reviewing and approving sewer and drainage facilities within the City of Portland. The 2020 manual improves clarity, updates technical requirements and clearly separates this manual from the City's Stormwater Management Manual (SWMM).

The City of Portland adopted the 2020 SDFDM in March 2020.
