Rainwater Harvester Mk.II
One 275-gal Grade B tote, two downspout adapters, a screen insert, and a proper spigot. Up to 8,000 gallons captured per year off a 1,200 sq-ft roof.
Over the years customers keep asking us to cut, drill, and re-plumb totes for uses we never imagined. So we started building them as stock items. Here are six that consistently ship — and if you've got a weirder idea, we'll build that too.
One 275-gal Grade B tote, two downspout adapters, a screen insert, and a proper spigot. Up to 8,000 gallons captured per year off a 1,200 sq-ft roof.
Cut-top tote with optional grow-bed conversion. Matches most backyard tilapia or goldfish-and-basil setups. Comes with sight tube.
Reconditioned tote, stainless camlocks, 12V diaphragm pump kit, and a rain cover. For farms and small fleet yards.
Four Grade C totes, strapping, sand-fill instructions, and a bulkhead drain kit. Deploy in 30 minutes, reuse for years.
275-gal potable-grade tote with a gravity-feed stand, first-flush diverter, and chlorine dosing line. Preppers and homesteaders: yours.
Four cut-top planters on a single pallet. Paint them whatever color you want. Mint grows absurdly well in these.
Every stock build on this page started as a one-off request we said yes to. Here's what happens between the first phone call and the tarp coming off on your driveway.
In April 2024 a repeat customer in Sharpsburg — a lumberyard roughly a mile off the Allegheny — called about chronic spring flooding on their south lot. The city would not fund a permanent berm and the property owner didn't want pour-in-place concrete. We built a deployable wall.
Pulled from winter industrial returns — solvent-prior, triple-rinsed at Stage 1 only since these never touch product.
Sand for the lower 40%, water above. Gives weight where it matters and makes the top rows drainable in under 20 minutes.
Eye bolts through the cage corners, strapped tote-to-tote with 2″ polyester ratchet webbing at 1,100 lb working load.
Four rows deep at the low end, two rows deep at the high end. Height 46″ — the standard 275 cage dimension.
Forklift sets the bottom course, crew tops and straps. Breakdown is about 40% faster than setup.
Lot stayed dry through two 100-yr rain events. Totes returned to our yard between events for winter storage.
Eighty percent of our custom builds come in as phone calls that start with "this is probably stupid, but…" — a partial list of things we have cheerfully made:
We don't say no often, but there's a short list where the physics, chemistry, or liability doesn't work out. We'd rather tell you up front than collect a deposit on something we can't stand behind.
A Grade C tote with undocumented industrial content isn't a municipal cistern even after a deep clean. We'll sell you a Grade A or rebottled unit for this, or point you at an NSF-rated polyethylene cistern.
HDPE walls are not rated for continuous pressure cycling above atmospheric. A cracked tote full of effluent is a disaster. Gravity-only, or no.
Local fire code and common sense. We'll build you an outdoor diesel day-tank with bund and signage, not an indoor one.
Stacked totes can hold weight short-term, but we won't build you a foundation, a deck base, or anything a person will stand on long-term out of used tanks.
HDPE softens at around 240 °F and stress-whitens far earlier. Anything exothermic or steam-heated belongs in stainless, not composite.
Fish are a canary. We'll rebottle or pull a documented Grade A tote for aquaponics — but we won't cut up a mystery tank and hope it holds.
If you'd rather cut and plumb it yourself, here's the five-item list we recommend before the first tool hits the plastic.
