Portland’s Approach to Rehabilitation of a 100-yr-old Brick Outfall

Centralized collection—using large diameter interceptors, trunk lines and transfer sewers—has frequently been the backbone of a wastewater collection system for centuries. In the United States, many large diameter sewers have been in service well past their design life, and consequently, we’re seeing more headlines in the local newspapers of sinkholes, pipe collapses and overflows taking place when these aging sewer systems fail. CH2Mer Daniel Buonadonna shared a case study on the City of Portland's strategy for rehabilitating one of its oldest brick sewers at the Water Environment Federation's Technical Exhibition and Conference (WEFTEC) this week.
