Rain Barrel: Overflow Alert
Rain Barrel: Overflow Alert
Tank Water Level Forecast
Download on the App StoreEnter your roof catchment area, collection efficiency and barrel capacity, and RainCatch converts the forecast into the water you can actually expect to collect. Gallons work too if you prefer them.
See how the level climbs across the coming days, which day the barrel tops out, and how much runs to waste as overflow.
If a storm is going to fill you past capacity, you'll know in advance — in time to draw water down and keep every litre you can.
Log each watering so your level stays honest. The forecast reflects what you actually use, not just what falls from the sky.
Set up several barrels and catchment surfaces — house, garage, shed — and see which one really earns its keep after the same rainfall.
Put the next expected collection on your Home Screen. Prefer to skip location? Enter the rainfall yourself and everything still works.
Use the footprint of the roof section that drains into your downspout — length times width as seen from above, not the sloped surface. A pitched roof catches the same rain as its flat footprint, so measuring from above is both easier and more accurate.
