Rainwater Collection

Hi Permies

I have/am setting up rain barrels at various gutter locations on a property located to be used for their nearby distribution. I have an above ground 1000 gallon cistern that I would like to divert overflow from each during large rain events. This probably must incorporate the use of pumps. Any ideas on a pump that would turn on during overflow then shut off accordingly would be appreciated.

Sounds like a Job for a sump pump.

Float switch, hooked to whatever kind of pump is available...

Thanks, those replies are what I had in mind yet trying to avoid. I have come up with alternatives.
