The New York City Department of Environmental Protection will be making major repairs on the Delaware Aqueduct from October 2023 through April 2024 (the project was postponed by one year in June 2022). The work requires shutting down and replacing portions of the aqueducts that connect three reservoir systems that supply drinking water to New York City, and carefully regulating each reservoir's capacity during the shutdown.
The Delaware River Basin Commission is maintaining a website with information on this project, which will be updated frequently. You can monitor the progress by clicking here.
