Public Encouraged to Provide Comment through June 23

DC residents who want to replace their lead service lines may soon have more options to do it sooner—without having to wait for construction to reach their block.  While the Lead Free DC Program replaces lead service lines at no cost, DC Water has proposed two updates to its program that would make it easier and faster for some residents to get their lead pipes replaced, especially those at higher risk of lead exposure. These proposed changes have been published in the DC Register and are now open for public review.
