I normally keep all the barrels covered. I took the cover off to take a picture of the inflow and overflow fittings from the inside, also I was trying to show the water flowing in and out.

Your setup sounds very good too. My house is too far from my garden and downhill from it to use grey water.

Sounds great. I would worry that once the barrels are somewhat filled, the downward pressure would send water out of the barrels through the barrel to barrel connections instead of in one and out the next. I suppose this is where it helps to have some knowledge of fluid dynamics.

Thank you for your comment. We have some rules where I live also, but I can take up to 500 gallons per day without a permit. My system doesn't take anywhere near that. Also my stream is just rainwater runoff from the hill behind my house. It isn't a protected river.
