Collection: Rainwater Harvesting Tanks (Dual Layer Water Tanks)

Our Dual layer tanks are popularly used for rainwater harvesting. We design them specifically to collect the rainwater that falls on your roof and keep it safe for use in your garden or filter it for drinking. 

Why harvest rainwater with a FLOU tank?

✔ your ecological footprint

✔ a sustainable source of freshwater for your lawn, garden beds, kitchen or cottage

✔ fresh water resources during droughts or dry spells

✔ protect our lakes from sewer overflow

✔ your holding capacity with a large capacity rainwater tank

FLOU tanks are designed for your home with colored to match techniques that suit the aesthetics of your property and stand neatly under your downspout. They are easy to set up (click here for installation guide), low on maintenance, built to last, and 100% recyclable.
