I have my doubts about whether rain water catchment in cisterns or barrels on the scale that you can do it at a suburban home is really useful. The amount of water that you can retain isn't all that much compared to the amount that's falling on your property - 50 to 100 gallons doesn't go that far which is what the majority of people can implement. Plus, you'll quickly use it up in the ~2 weeks after the rain storm, and then you're left with the ugly barrel all dry season long.

A far better solution (and one I am trying to implement) is to shunt the rain water to permeable ground so that the soil can retain water for you. You can store far more water for far longer this way than in a barrel.

Still, I'm aware that I might be wrong and I'm curious about what the seminar has to say so I'll try to go.


  1. I visited homes and hotels in Australia with huge barrels of ~2 meters in diameter. They were half buried and colored a dark green. One hotel had a whole row of them along the service side of the building.

    One home with two treated them like berms in their landscaping scheme. It looked attractive and was functional for Adelaide's weather.

    My townhouse's yard is too small for one of those. Moreover, we have wet and dry seasons. We can't store enough water to get us through 6 dry months. They need only hold enough water to get them 3-4 weeks between storms.

  2. You have given important information. Apart from that today
