How it works
The closed-loop catchment system
Eave to aquifer: every drop is captured at the roofline, filtered, and stored for your landscape and home.
01
Roofline Extraction
Heavy-gauge 0.032 aluminum 5" and 6" seamless gutters and oversized 3"×4" downspouts shed debris and manage high-velocity torrents.
02
First-Flush Diversion
Self-cleaning debris filtration and first-flush diversion keep rooftop sediment and organic matter out of storage.
03
Artisan Tank Storage
USA-made 20-gauge galvanized steel cisterns by Texas Metal Tanks, plumbed directly to your irrigation or backup domestic line.
