This could be useful but for some, including us, rainwater collected from our roofs would need careful filtering to remove moss and dust or I would expect a small pump, and a sprinkler system, to become clogged. As do the taps at the base of our butts, sometimes. The growth of algae etc. in the collection butts would also have to be controlled. Without filtering and algae control the water we collect would not be clean enough to wash cars.
Thus for some, something like this would be good, but with a larger and more sophisticated collection tank, with filtration.

I’ve got water on the brain (figuratively, not literally) this week, so the solar-powered RainPerfect gadget caught my attention as something that would be useful in my own backyard.
The $139 product from Rule Industries combines a pump with a solar panel to pull water out of your rain barrel and water your lawn, run a low-pressure sprinkler or act as an aid with other irrigation activities.
The solar panel charges a NiMH battery to make the pump work; a single charge can pump up to 100 gallons of water at 13 PSI. RainPerfect can be used with rain barrels that range in capacity from 40 gallons to more than 65 gallons; it screws onto the barrel.
The RainPerfect product comes with a limited warranty of 1 year in the United States (two years in Europe).
