Backflow Service Providers

Important Announcement:

On June 3rd, DC Water will disable the backflow prevention assemblies (BPA) module on the Third-Party Portal (3PP) and launch a new online portal, Acquaa, for viewing and reporting backflow prevention assemblies (BPA). 3PP will be available for other uses by third parties.

Approved Backflow Prevention Assembly Service Providers.

A list of approved backflow prevention assembly (BPA) service providers is available at the links under the resource files section to the right.  The listed BPA service providers have been independently certified to test and/or install a BPA, registered on our Third-Party Portal, and have been instructed on submitting inspections to our Third-Party Portal. Only those BPA service providers listed are authorized to submit results to DC Water to bring your BPA in compliance with applicable regulations.

Use the legend below in selecting the appropriate BPA service provider. For example, if you are a residential customer that needs to have their backflow preventer inspected, you may contact any service provider that is shown as a residential inspector in column I.

This list is updated monthly.

First turn of cutterhead signals the start of excavation for the Potomac River Tunnel Project

In a defining moment for one of the District’s largest infrastructure investments, DC Water has marked its next major milestone in the Potomac River Tunnel Project. The first tunnel boring machine, Mary, has launched her northbound journey breaking through the soil to signal the start of excavation.

With the first turn of Mary’s drill-like cutterhead underground, the machine pushed forward to begin tunneling, representing the transition from years of planning and preparation to active tunnel construction on the $819 million project.
