Series 2026 Bond Transaction Delivers Significant Long-Term Cost Savings

DC Water has closed on a refinancing deal for its Series 2026 bonds that will save customers millions of dollars and keep rates affordable across the District. The refinancing transaction, which closed this month, delivers approximately $54 million in budget savings over the next twenty years, directly benefiting DC ratepayers through reduced costs.

The deal refinances existing bonds tied to capital infrastructure projects, backed by DC Water’s high bond ratings to secure a lower interest rate that resulted in about $2.9 million in annual debt service savings.

These savings underscore the Authority's ongoing commitment to financial health and sustainability, ensuring that essential water and sewer services remain affordable for more than two million residents and businesses in the region.

Earlier this year, all three major agencies - S&P Global Ratings, Moody’s Investors Service, and Fitch Ratings - reaffirmed DC Water’s top-tier ratings, recognizing its strong financial management, independent rate-setting authority, and prudent capital planning. These high ratings allowed DC Water to achieve favorable terms on the refinancing, providing access to low-cost capital, which translates into lower rate increases for customers and long-term affordability.

These bonds support DC Water’s $9.6 billion Capital Improvement Program, funding key upgrades such as the Potomac River Tunnel for the Clean Rivers Project, the Lead Free DC initiative to replace lead service lines across the District, rehabilitation of the 54-mile Potomac Interceptor sewer system, water main replacements, and equipment upgrades at Blue Plains to ensure reliable service for customers and stakeholders across the region.

DC Water remains committed to leveraging financial tools and maintaining top bond ratings to maximize cost savings and protect affordability for all ratepayers.

DC Water Breaks Ground on Piney Branch Tunnel, Final Phase of DC Clean Rivers Project

Today, DC Water broke ground on the Piney Branch Tunnel, the final major tunnel in our Clean Rivers Project. This work will help keep sewage and trash out of local waterways and make Rock Creek, the Potomac River, and the Chesapeake Bay cleaner for our community.

When we finish the Piney Branch Tunnel, it will hold at least 4.2 million gallons of rainwater and wastewater during heavy storms. Instead of overflowing into Piney Branch, that water will go to the Blue Plains Water Resource Recovery Facility, where it will be treated.
