Each year more than 450 municipal officials, engineers, managers, public works directors and wet weather experts attend the 3 Rivers Wet Weather Sewer Conference to learn, educate and share experiences for overcoming the wet weather problems that have plagued the Pittsburgh region for decades. Some 75 exhibitors share their products and services while local, regional and national speakers presented educational sessions on a variety of wet weather issues.
