This Sewer and Drainage Facilities Design Manual ('Sewer Design Manual” or “Manual') 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. This 2006 version of the Manual replaces the 1991 Sewer Design Manual. The Manual provides information on City design standards and criteria.
Using and following these standards can expedite a project's preparation, review and approval. These adopted standards help to ensure uniformity throughout the City's sewer and drainage system. Facilities designed in accordance with this Manual will meet the City's performance objectives and improve system operation and maintenance efficiency. Compliance with these standards does not relieve a designer from the responsibility to apply conservative and sound professional judgment when designing City-owned facilities. All Manual users are responsible to review and verify the applicability of the methods and materials presented herein as they pertain to the specific project under design. The standards set forth in this document are minimum standards and are intended to assist but not substitute for competent work by design professionals. Designers preparing a project and following these standards shall also take into account such matters as environmental impact, maintenance of pedestrian and vehicular traffic patterns, maintenance of existing and proposed utility services, constructability, system maintenance and sustainability principles.
Only when applying these standards and considering other such factors, can public facilities be designed that are both cost effective and that provide long-term economy of operation and maintenance.
