Above Ground Septic Tanks

Premium, Practical, & Portable Waste Management Solutions
When underground installation isn’t possible, aboveground septic tanks—also known as waste holding tanks—provide a reliable and flexible alternative. These tanks are perfect for temporary or permanent wastewater storage in areas with high water tables, rocky terrain, or limited space....

Lightweight yet durable, aboveground tanks are easy to transport and install, making them ideal for construction sites, seasonal properties, and remote locations. Their low profile build makes them ideal for many situations. They come with a lid and most of them already have molded-in fittings and multiple flat spots for additional plumbing options. At Tank Depot, we offer aboveground tanks from trusted manufacturers like PolyJohn, Quadel, Ace Roto-Mold, and Norwesco, with capacities ranging from 200 to 500 gallons. Built from corrosion-resistant polyethylene, these tanks are designed to withstand harsh environments while ensuring safe and sanitary wastewater storage.
