About

WSSC FHP

Features
Read full description

WSSC Fire Hydrant Painting (FHP) is an enterprise field-service mobile application built for authorized contractors working on behalf of the Washington Suburban Sanitary Commission (WSSC Water). It is a workforce tool — not a consumer app — used by professional painters and crew leads to manage, document, and complete fire hydrant inspection, painting, and maintenance work orders across WSSC Water's service area. Key features: • Offline-first work order management. Painters can view all assigned work orders, hydrant lists, and asset details even without network coverage. Changes sync automatically when the device returns online. • GPS-verified photo capture. Before-and-after photographs of each fire hydrant are captured with precise location coordinates stamped at the moment of capture. The app verifies the painter is within proximity of the hydrant's stored location, supporting work-integrity standards. • Condition logging. Painters can record observed conditions on each hydrant (rust, damage, obstruction, broken caps, etc.) with structured selections for consistent reporting. • Inclement-weather logging. Crews can record days when weather conditions prevented work, with same-day timestamping and downstream backend integration. • Daily summaries. A built-in daily report shows work completed that day, total hydrants serviced, and a summary view for daily standups. • Spanish localization. The interface is fully translated, supporting bilingual crews. Access to WSSC FHP is restricted to authorized WSSC Water contractor accounts. Member accounts are provisioned through WSSC Water's contractor onboarding process — public users will not have valid login credentials and will not be able to use the app. Data is encrypted in transit. Crash diagnostics are sent to a secure monitoring service (Sentry) to help maintain app reliability. See the Privacy Policy linked in the listing for full details on data collection.
