In this video Rob showcases one of the major water harvesting feature – an underground rainwater cistern – on Rob and Michelle’s urban home property.

This rain tank is unique because it is integrated into our hardscape (patio) so it’s completely invisible to the untrained eye.  In this video I talk about how it was built, how it fills, how it’s integrated into our rain garden and passive solar greenhouse, and details on the sump pump, drains, overflows, and swales.

    Hello Rob,
    Wonderful video and wonderful work of harvesting rain water. I am still at a loss trying to figure out some simple system to harvest rain water from one of my rain spouts. One of them is directed to the Permaculture food forest whilst 3 others on the property are just going to waste. Keep up the good work!

    Thanks Rob and Verge for this video. It is concise and well documented. I appreciate this as we venture into rainharvesting techniques on our own home here in Calgary. I know that you have the other large tank on the North side of your home and wonder if that catchment is now used strictly for the food forest out front. I don’t want to overdesign and wonder if one of those systems is prefered over the other?

      The underground tank is used for the greenhouse. The food forest has its own tank however the tank is used to irrigate the salad greens.
      Thanks for the comment.

    Thanks for this. I am considering upgrading from 4 rain barrels to something underground. This is one more option to consider. It looks obvious once it is installed, but I imagine that there was a lot of head scratching before you came up with this.

      Yes, but it really is quite simple. There are a lot of benefits to this solution.

    That’s such a great system, Rob- It was great to see this step-by-step video, as during our PDC we went through your process very quickly, so this was very educational. This obviously works best in a system with a grade, so you can move that water on down towards the garden, unless you want to use a pump all the time. Nice video!

    Looks awesome! Something to keep in mind for when we are putting in rainwater catchment for our new place. Thanks Verge 🙂
