The Potomac Interceptor Sewer (PI) has been in service for more than 50 years. During that time, the pipeline has been an ongoing source of odor complaints from nearby residents and park users. The odors that were the basis for the complaints were emitted from a series of vents along the pipeline. Many of these vents were located on land owned by the National Park Service and are part of the Chesapeake & Ohio (C & O) Canal Historical Park. In 1999, DC Water embarked upon a journey which would help to resolve the odor complaints as well as to extend the service life of the PI. When the journey started, DC Water had no idea that the project would take more than a decade to come to fruition. After more than 10 years of permit related delays and another 3 years of construction, the project is nearing completion.
