Norwesco 41319 Legacy Septic Tank, 300 gal Tank, 1 to 20 in Manhole, Polyethylene, Yellow

Our spheres are designed to be used as a holding tank or pump tank. Unlike our ribbed tanks, these tanks may remain in the ground when empty. However, they should not be installed in high water table or high clay areas. These tanks are furnished with manhole covers and include a molded in elevated pump stand on the bottom of the tank.
