these look really nice! i assume the black hose is long enough to carry excess water away from the house and that a hose can be connected to the faucet? is there a barrier to pevent mosquitoes from breeding. i was going to find a kit to make mine, but this is a good cause. right now i have other priority expenses and will have to live with my not so perfect makeshift garbage cans, but look forward to ordering when i can...oh, how many gallons each?
