Network Efficiency and Water Losses: DC Water
Network Efficiency and Water Losses: DC Water
DC Water is renewing its network through one of the major sustained municipal water-and-sewer capital programmes in the United States, executed under a Federal consent decree binding to 2030.
This report examines how DC Water links network efficiency to renewal pace, digital metering maturity, Lead Free DC delivery, Clean Rivers compliance, and bond-market credibility through the 2030 execution window.

The Five Strategic Pillars
-
Architectures: Linear-Asset Renewal at Scale
150 miles of small-diameter water main replacement and full Potomac Interceptor rehabilitation funded within the FY 2025-FY 2034 $9.6 billion Capital Improvement Program establish a programmatic renewal pace across approximately 1,300 miles of water mains and 1,800 miles of sewer mains.
-
Enablement: Settled Advanced Metering Infrastructure Base
More than 85,000 meters with daily reads since February 2017, paired with the High Usage Notification Application and the MyDCWater portal, anchor the digital base for apparent-loss control, billing accuracy, and customer-side leak compression.
-
Resolution: Lead Free DC and Service Line Removal
The Lead Free DC programme at approximately $1.8 billion targets more than 51,000 service lines for replacement by 2030, with inventory discovery continuing to expand scope after the 2024 brass-line addition.
-
Alignment: Consent Decree and Board Governance
The 2015-amended Environmental Protection Agency Clean Water Act consent decree binds Clean Rivers delivery to 2030, with Blueprint 2.0 Board oversight and independent rate-setting authority providing the institutional discipline for efficiency commitments.
-
Capability Building: Financing-Backed Execution Capacity
AAA senior-lien rating reaffirmed for ten consecutive years, $156 million Water Infrastructure Finance and Innovation Act loan at 2.33 percent for 40 years, Century Bond precedent, and Environmental Impact Bond innovation establish the financing capacity required to sustain programme delivery through the 2030 window.
Operational Excellence & Resilience
DC Water operates an integrated water network supported by Board governance, capital planning, and consent-decree delivery. Performance is achieved through small-diameter main replacement, Potomac Interceptor rehabilitation, and Lead Free DC execution. This is further supported by Advanced Metering Infrastructure, the MyDCWater portal, and High Usage Notification Application alerts. Key performance is reflected in approximately 1,300 miles of water mains and 1,800 miles of sewer mains. This is reinforced by more than 85,000 meters and more than 97,000 customer notifications.
The FY 2025 to FY 2034 capital programme funds network renewal, Lead Free DC, Potomac Interceptor rehabilitation, Clean Rivers delivery, and Blue Plains upgrades through the 2030 compliance window.
