The Norwesco 525 Gallon Underground Water Storage Cistern is a buried polyethylene cistern built for sites where storage has to disappear below grade. With a 64-inch by 64-inch footprint standing 62 inches tall, it holds 525 gallons of water out of sight. For homesteads on a well with limited daily yield, rural properties banking water for irrigation or fire reserve, and any install where an above-ground tank is not an option, an underground cistern keeps the supply protected from freeze, sun, and sightlines.
Will it work for your site?
This is a white polyethylene tank measured at 64 in long by 64 in wide by 62 in high, a nearly cubic shape that drives the dig more than the height does. The verifiable specs at a glance: 525-gallon capacity, 64 x 64 in footprint, 62 in tall, roughly 4,378 lb when full of water, white polyethylene. Plan the excavation, bedding, and backfill around that full-water load, and engineer the install to resist flotation when the tank sits empty in a high water table. If you are sizing a cistern against your well's recovery rate or your household and irrigation draw, run the numbers with our Tank Sizing Calculator and the Tank Sizing Guide so the 525-gallon capacity actually matches your demand instead of guessing.
Installation and the mistake to avoid
The most common underground-tank failure is not the tank, it is the burial. An empty buried tank wants to float, and improper bedding or uneven backfill can deform the shell, so follow Norwesco's burial instructions for inlet, outlet, and access placement before you set it. Just as important: this listing does not carry confirmed fitting sizes, so call 866-418-1777 to confirm inlet, outlet, riser, and manway penetrations before you order, because reworking those after backfill means digging the tank back out. Before commissioning, fill and pressure-check every fitting and watch the pad for settlement; our hydrostatic test methodology guide walks through the water-fill discipline, hold-time math, and leak detection that catch problems while the tank is still accessible. If part of your reserve is earmarked for private fire protection, our fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection for this kind of stored water storage tank.
Freight and ordering
