DC Water today announced the launch of Pure Water DC, a groundbreaking program designed to strengthen the District’s water supply resilience and secure a second source of drinking water for the nation’s capital. To kick off this initiative, DC Water convened a panel discussion along with industry experts, utilities, and federal and state regulators from across the region. The panel explored practical ways to make our water supply more resilient, including advanced water reuse —a growing solution nationwide to address vulnerabilities in the water supply. This method relies on advanced treatment processes to purify water to drinking standards so it can be safely recycled for various purposes.

Panel discussion to bring together key partners on the path forward

On November 19, DC Water will launch an ambitious effort – Pure Water DC – to reduce the District’s reliance on the Potomac River as its only water source. We’ll be hosting an event to outline our vision and strategy for resilience and host an expert panel to address one of the most critical challenges facing the nation’s capital.
