The North Interceptor Sewer Improvement Project is the largest and most significant infrastructure project to take place in Newburgh for several decades. The US$32m investment, aimed at protecting the water quality of the Hudson River, commenced construction in April 2022 and will be completed in spring next year. At completion, the project will have installed 2,652m of new, larger-gravity sanitary sewer piping.
