Collections Systems Committee

The Collections Systems Committee (CSC) facilitates the advancement of standards and methods used for the design, construction, operations, maintenance, and management of wastewater collection systems in the Pacific Northwest.
While we focus on a wide range of collection system topics, the committee has recently developed subcommittees based on several specific areas that we believe are of particular importance to the PNCWA community.  These topics represent areas of industry growth, technology advancements, or opportunities to knowledge share with other practitioners.  The following is a list of these technical subcommittees with primary points of contact, and we would welcome your input to join the conversation.

As a committee we are committed to educating the industry on collection system issues, having presented collections workshops and webinars (such as Effective Sewer Line Cleaning), submitted articles to the PNCWA Newsletter, and sponsored Collections Systems Pre-Conference Workshops and Technical Tracks during the PNCWA Annual Conference.  We meet bi-monthly via conference call to conduct committee business. For more information and to be included on these future calls, please contact Committee Chair Jeff Schmidt at [email protected]

Taggart Sewer Outfall Repair - Portland, Oregon

Construction continues on the 114-year-old Taggart Outfall—a large, brick sewer tunnel located deep underground. This critical sewer line serves Southeast Portland. Repairs will increase the sewer’s resiliency, extend its service life for up to another 100 years, and help prevent sewage releases.  Learn more about this project here.

Explaining Collections Systems: No Pipes, No Plants

"Collection systems" refers to the system of underground pipes and maintenance structures that are used to convey wastewater to a wastewater treatment facility. The use of collection systems has brought dramatic improvements to public health in major cities. Most sewers carry wastes from households and commercial establishments and are referred to as sanitary sewers. EPA estimates approximately 500,000 miles of publicly owned sanitary sewers with a similar expanse of privately owned sewer systems. Continue—see for yourself!
