That awesome storm!
The setup is easy: pump, funnels and watering can.
After such a nice rain, not only can I forego watering for a few days, but next time I do, I can water the garden and new trees/shrubs for several days on the rainwater I have collected. I don’t have to turn on the hose.
I submit there is tremendous potential for rainwater collection for use on gardens; (lawns are a different story that needs revision in a desert). It looks promising for gardens, however.
It’s easy to get started.
Have fun!
