The free DOWSER App is aimed at all interested emergency services who have always wanted to digitize their water intake points or who need a quick overview of existing water intake points on the way to the operation site, if the local network has already been updated. The DOWSER App provides you with a functional tool, which you can use conveniently on your iPhone while on the road. A great advantage of the DOWSER App is the guarantee that no trial membership, long-term commitment or payment for the use will come your way. DOWSER is and will remain free of charge and its range of functions will not be restricted at a later time! This is made possible, thanks to a current research project, where the digitization of existing documents and materials from authorities in the area of fire-fighting stands in the foreground. Range of functions: Water intake points at the site The DOWSER App provides you with the ability to show water intake points in your immediate surrounding on a street map. A separate listing of all water intake points in your vicinity allows maintaining an overview. A new "feature" is the display of water intake points in your vicinity sorted by the distance from your location. If you are on the way to the operation site, using the DOWSER App you can inform yourself at any time in advance about available water intake points. If you want to get a faster overview of the situation on the ground with the direct input of address data, the DOWSER offers this functionality. A click on a specific water intake point discloses the important details such as nominal diameter, flow rate, type of water intake point and other important information. Enter water intake points With the DOWSER App you have the ability to enter your own water intake points and in the long term you contribute to a complete digitization of all water intake points. Your personal profile keeps track for you of your already stored water intake points. Rating of water intake points A special highlight is the rating option in the DOWSER for already registered water intake points. Mostly positive ratings cause that water intake points continue to be displayed in DOWSER. However, if the negative ratings outweigh, the respective water intake points will no longer be displayed by the DOWSER app. As a future "feature" also the local network operator will be informed. DOWSER thereby is pursuing the vision to not only provide emergency services with a functional tool, but also convinces with comprehensive information about the respective water intake points. Trust the DOWSER App when water as a resource becomes the lifesaver. DOWSER - When a situation becomes risky...

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.
