The first version (beta) of the LWR tool (lwrtool.ch) is released.
We transformed a leaflet (Löschwasser-Rückhaltung, PDF, awel.zh.ch) into a web app conceptualized as a Progressive Web App (PWA). It is a supracantonal tool used for the calculation of the extinguishing water retention volume of warehouses.
The LWR tool (lwrtool.ch) is intentionally reduced to the essential, intuitive and can be used across devices. At the same time it is educational and informative - if required, calculation bases, tables, additional information or tools can be accessed directly.
Install it as an app on your device; use it offline; check necessity of fire water retention; calculate the required fire water retention volume; uses the local storage - close the app and continue later; share a link that recovers your entries; generate a report (PDF) of your calculation with added information; become a water retention volume expert through info boxes and additional information on the website.
