The study utilized a risk-based approach to identify those sections of a 23-year-old concrete interceptor most likely to be experiencing hydrogen sulfide deterioration. This approach made it possible to reduce the footage of pipe that was to be internally inspected with robotic equipment. The approach utilized accepted equations for the production and release of hydrogen sulfide gas to model the corrosion characteristics of the interceptor. The initial modeling was refined with a limited amount of field investigation and data gathering. The internal inspections, which were conducted on approximately 23% of the 92,000-linear-foot (lf) Shades Valley Transfer Line (SVT), correlated well with the worst segments predicted by the model, thereby validating the approach. This approach saved 350,000 when compared to the inspection of the entire line and yielded additional value in the hydraulic analysis made possible by the modeling effort.
