Septic Pump Tanks

Reliable Wastewater Solutions for Low Drainage Soils
When gravity alone isn’t enough to move wastewater, septic pump tanks are the perfect solution. Designed for properties with elevation changes, poor soil absorption, or uneven terrain, these tanks use pumps to efficiently move effluent from the septic tank to the drain field. Whether for residential, agricultural, or commercial use, septic pump tanks ensure effective wastewater treatment even in the most challenging environments....


Our sphere pump tanks are designed to be used as a holding tank or pump tank and they can remain in the ground when empty. Our septic pump tanks come in sizes ranging from 200 to 500 gallons and are built by trusted manufacturers like Snyder Industries, Norwesco, and Ace Roto-Mold. Made with high-quality polyethylene, they’re durable, watertight, and designed for long-term use.
