This is the official product video for the Norwesco 500 Gallon Above Ground Septic Holding Tank. Full specifications, dimensions, and live pricing are on the product page.
In a world where wastewater can be heavier than water... a black polyethylene guardian stands above the ground. The Norwesco 500 gallon above-ground septic holding tank is a holding tank — not a treatment or leaching tank — it collects effluent and is pumped out on a schedule... At 500 gallons of plain water the contents weigh roughly 4,170 lb, but the 1.9 specific gravity rating means the shell is engineered to safely contain contents up to about 7,923 lb. Low-profile at 22 inches tall, its long 52 x 130 inch footprint spreads the load. An 8" threaded lid is the single point of access... Plan inlet, outlet and pump-out connections through that port.
