The Seed is Baba Yaga’s Hut…
Dear Readers,
As much as I believe Baba Yaga is a complex, terrifying, and intrinsically beautiful character in Russian fairy tales…I don’t necessarily want our home to look like her hut. And the two Clivus Multrum composting tanks do exactly that…they make The Seed look like it has two chicken feet.
The conundrum:
The U.S. designs of the Clivus Multrum are tall. In the design above, we have two M2 models of the Clivus Multrum. They are each designed for an average of 15 daily uses, and to accommodate three people. They each are between 6.5 and 7 feet high, and that height does not include the required 12’’ of extra space above the tank for ventilation equipment. These compost holding tanks will also be enclosed in the home’s envelope, and therefore would require additional height allowances.
The height becomes a problem due to the fact that William and I want to avoid digging. For prefabrication purposes, it is easier if we do not have to dig in order to install the tanks. For our own personal purposes, we simply want to avoid disrupting the natural soils on our land as much as possible.
Two Possible Solutions:
One, we could go Aussie. The Australian versions of the Clivus Multrum are significantly lower in height. A CM10 model is designed for an average of 25 daily uses, and is only 3.6 feet high. While the Australian version is certified to Australian and New Zealand wastewater treatment standards by SAI Global…they are not NSF certified. From my little research into PA DEP code, only NSF certified wastewater treatment products will be considered as acceptable.
