The Norwesco 1000 Gallon Multi-Use Underground Liquid Storage Tank (SKU N-41734) is a blue polyethylene "Bruiser" tank engineered for below-grade water storage where surface real estate is at a premium. It holds 1,000 gallons and measures 63" high by 60" wide by 102" long, giving you a 60.0" x 102.0" footprint to plan your excavation around. If you've been hunting for a 1000 gallon underground storage tank that disappears beneath the yard while keeping a full reservoir on call, this is the body built for that job.
Will it work for your site?
This is an underground tank with a 63" x 60" x 102" envelope and a 60.0" x 102.0" footprint, so size your excavation around those numbers. Full of water it carries roughly 8,340 lb, which means the excavation, bedding, and backfill all have to be engineered to carry that load and to resist flotation when the tank sits empty in wet ground. Underground polyethylene tanks live or die by their burial detail, so confirm your burial depth, anti-flotation anchoring, bedding material, and any traffic-load rating against Norwesco's N-41734 installation instructions before you excavate. One more honest gap to close at quote: this listing doesn't publish a fitting schedule, so confirm the manway/lid size, inlet/outlet locations, and any bottom-drain configuration with us at 866-418-1777 before you plumb it.
Size it before you dig
The hole only gets dug once, so right-size the reservoir first. Our Tank Sizing Calculator and Tank Sizing Guide walk you through matching 1,000 gallons of underground storage to your draw rate and refill schedule. If you're using this as a buried fire-water reservoir for a rural or remote site, the Fire-Water Reservoir Tank Design guide covers NFPA 22 sizing discipline and the freeze-protection thinking that matters once a tank is in the ground in a cold climate.
The mistake to avoid
This Bruiser is rated for water service only: the listing carries no specific-gravity rating above 1.0, so don't put a heavier-than-water or chemically aggressive liquid in it. If your stored solution is denser than water, you need a tank specified for that exact duty and specific gravity instead - call 866-418-1777 and we'll match you to the right body rather than risk this one. The other common miss on underground tanks is skipping the anti-flotation work and the proper bedding because the tank "looks tough" - polyethylene buried wrong will deform or float, so treat the installation as seriously as the tank itself, per Norwesco's install guide.
