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.

We have presented collections workshops and webinars such as Effective Sewer Line Cleaning, submitted articles to the PNCWA Newsletter including the Fall 2015 Newsletter which focused on Collection Systems, and sponsored collections systems tracks during the Annual Conference.

We meet quarterly to conduct committee business.
