It is raining gently at the moment.
The lawn is still parched.
The water butt is full.

It has occurred to me that perhaps I should keep half emptying the
water butt and chucking the water on the grass so I don't waste the
water coming off the roof.

Any downside to this strategy?
[Apart from doing it whilst it is still raining.]

Erm, are you joking?
Use your water.
