Rep. Nancy Mace Secures Major South Carolina Wins As House Passes Water Infrastructure Bill

WASHINGTON, D.C. (Sept. 16, 2026) – Congresswoman Nancy Mace announced today the House passed the Water Resources Development Act (WRDA) of 2026, delivering critical water infrastructure, flood protection, and water supply investments to South Carolina.

Mace secured multiple South Carolina priorities in the legislation, including water and wastewater infrastructure in Hilton Head Island, Isle of Palms, Berkeley County, and Beaufort, as well as expanded authorizations for projects tied to Lakes Marion and Moultrie. This totals $100 million in authorized funding for water and wastewater infrastructure in the Lowcountry. The legislation also delivers for Charleston by integrating coastal storm risk management and tidal and inland flood management. 

“South Carolina is the fastest-growing state in the country, and our infrastructure needs to keep pace,” said Congresswoman Mace. “We made sure South Carolina’s priorities were front and center in WRDA, from stronger water and wastewater systems to better flood protection and infrastructure built for growth. These investments will make a real difference for families, businesses, and communities across the Lowcountry. This is what putting South Carolina first looks like.”

The South Carolina priorities secured by Mace include:

• $10,000,000 authorized for water and wastewater infrastructure, including stormwater management, in the town of Hilton Head Island, SC.
• $10,000,000 authorized for water and wastewater infrastructure, including stormwater management, in the city of Isle of Palms, SC.
• $14,000,000 authorized for water and wastewater infrastructure, including water supply and distribution systems, in Berkeley County, SC.
• $60,000,000 increase in authorization for wastewater treatment and water supply treatment and distribution projects related to Lakes Marion and Moultrie, SC.
• $6,000,000 authorized for water and wastewater infrastructure, including water supply and distribution systems, in the City of Beaufort, SC.
• Modification of the project for coastal storm risk management in the Charleston Peninsula, SC, to include features for tidal- and inland-related flood risk management measures.
• Deauthorization of Tidewater Reach section of the Charleston Harbor navigation system (adjacent to the Union Pier Terminal). This deauthorization will take effect upon completion of the sale of the Union Pier Terminal and the cessation of commercial port operations at the Union Pier marine terminal by the South Carolina Ports Authority. This will allow for the future redevelopment of the area by a private developer.
