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.
