Lots of discussion this week around Water Storage systems. We explored a number of options for storage but ultimately ended up deciding on installing Polyethylene tanks into basement.
Options considered were Made in BC, and NSF Food Grade
Pro: Good volume per sqf of floor, Moderately Priced, Easy to clean,
Con: Must be tethered to foundation so it doesn’t lift building (in flood)
Concrete tanks (built in place)
Pro: Highest volume per sqf, best integration into building
Con: Expensive, difficult to build proper lid, would require proper engineering, waterproof concrete additives expensive, High water table added a lot of engineering, material and labour costs,
Concrete Tanks (pre-formed)
Pro: Simple to install
Pro: Inexpensive, Flexible, no need for tethering (due to high water table), inexpensive shipping
Con: harder to clean, Least volume per sqf
Our goal is to install the equivalent of 12” diameter duct into a trench around the perimeter of the building. This trench will simply act as a method of cooling the fresh air supply in the summer or warming it up in the winter. We will be using 100” of polyethylene Big “O” similar to the material used in perimeter drains.
