Author Renee Dang here. Your request has been duly noted! Thank you for that suggestion.
I have received several requests from others in colder climates looking to build these systems either underground or heated. I plan to make this the 3rd book in the series very likely (the 2nd one being about rainwater treatment and purification), but in the meantime, please check out the amazing "Essential Rainwater Harvesting" by Michelle and Rob Avis.
They live in Canada and their book goes through the details for the design details of a system that can withstand freezing temperatures. The only downside of the book may be that there aren't as many details to build a cold-weather rainwater system on a DIY basis, and the book is rather technical, but it is a great starting place nonetheless. They really know what they're talking about.
Hi Renee, I’m especially interested in the book on treatment and purification, any thoughts on when that might hit the shelves? My situation is a little trickier, in that the water collected might sit for six months or so before being used, so safety (and lack of growing things) is of keen interest to me. I know the general principle is to run it through sand and charcoal but I feel like I need to know more about the specifics of a practical system. (And designs that I can copy [with info on possible modifications] would be my dream, as it would allow me to buy and preplan everything before expeditions to the remote site.)

Thanks, Renee Yes, I'm aware that building a system underground in zone 4b WI [soon to be zone 5] means that I must consider how deep the frost can reach here [Between 60-70"], and since I am in sand, I must also contend with caving in from the sides, so a cistern would have to be built very sturdy. I am looking to bury septic tanks that would be connecting amongst themselves near the bottom. I like the idea of buried concrete tanks because:
1/ being buried is the intended purpose of a concrete septic tank, so it is made to sustain the sideways forces of the ground.
2/ it is built with an access hatch so a person can enter it to apply some waterproofing layer that will also keep the water drinkable. [I'm researching what is the best waterproofing system and should it be applied to the outside of the tank before it is sunk in the ground?]
3/ I'm hoping that by sinking several tanks side by side, that will also reinforce against the ground pressure from the sides.
4/ The whole system can be buried to respect the frost line requirements.
I'm looking forward to your next bock, and thank you for responding.
