Saving rain water

Well, we would if it would rain. Georgia, or at least Atlanta, are devoid of precipitation, it seems.

City of Atlanta water is really expensive. Something about investment in new sewers or something, but it's an incentive not irrigate vegetables with the stuff out the taps and Steff's veggie garden will need plenty.

So we got a tank and I plumbed it into the gutters as well as the A/C condensate waste and the pressure release valves of the water heaters.

The A/C should give around 10gallons a day on a hot day and there will be 2 units when the downstairs apartment is up and running.

The tank is 330gal which would be filled by a rain fall of less than half an inch for that much roof.

2 gutters feed it from either side, but i have not figured out what to do when it overflows.
