2000 gallons, 9000l, 9m^3. Decent lawn size of 10 x 20m gives just an
equivalent of 4.5cm or 1 3/4" of rain. Nothing over a few hours or few
releases over a day or two. A lot would depends on how well drained the
garden is, a clay subsoil close to the surface could present a problem
but sand or gravel not.

Thanks to everyone for their input. I'm leaning heavily towards the
letting-it-all-out-on-the-grass idea. We definitely don't have clay soil,
and I would say the soil is free-draining.

The only trouble is that the whole back garden slopes towards the house,
but hopefully, it'll be OK if I let it out a bit at a time.


You could always give the kids a bucket each and tell them to empty it. It's
there for their benefit after all. It's not too soon to threaten them that
Santa won't come is it?
