DC Water accepts Third-Party Portal submissions only from registered BPA service providers on this roster. This page is a searchable local copy of the official Excel/PDF. It is not an official DC Water site.
The spreadsheet’s “Fire Hydrant Use Permit (FHUP) BPA Inspection” column is about hydrant-permit inspections — not a fire-line tester mark. This page does not invent a fire-line filter.
Must-be-on. Only listed providers may submit backflow tests through DC Water’s Third-Party Portal.
Service types as printed. Commercial vs residential installer/inspector flags come from the spreadsheet. FHUP is hydrant-permit inspection, not fire-line work.
Official fields only. Company, tester, mailing address, phone, email, and the five service-type columns. No hours, prices, or maps.
