Two key U.S. senators have unveiled bipartisan draft legislation that would authorize $19.5 billion for Army Corps of Engineers flood protection, ecological restoration and other projects, as well as Environmental Protection Agency wastewater treatment and drinking water programs, more than double the funding the last water package provided.

If approved and enacted in 2020, the two-bill package, drafted by Environment and Public Works Committee Chairman John Barrasso (R-Wyo.) and the panel’s top Democrat, Tom Carper of Delaware, would continue the recent practice of passing a water infrastructure measure every other year.
