This 1,425 gallon low profile underground water tank is built for installations where above-ground storage is not practical or permitted. Constructed from polyethylene, it is designed to be buried underground, keeping stored water protected and out of sight while preserving usable surface space above.

The low profile shape - 51'' tall with a 60'' width and 157'' length - makes it well suited for sites with limited burial depth, such as properties with shallow soil, high water tables, or space constraints that rule out taller vertical tanks. Two manway lids provide direct access for filling, inspection, and maintenance without requiring excavation of the entire tank.

Underground water tanks like this one are commonly used for rainwater harvesting, site water storage, irrigation reserves, and emergency water supply applications where a buried solution is preferred. The polyethylene construction resists corrosion and is compatible with water storage. At 445 lbs., this tank ships via freight and is available from multiple distribution points across the country. Additional fittings beyond the two standard manways are available - contact us for details before ordering if your installation requires specific inlet, outlet, or vent configurations.

Key Features:

• 1,425 Gallon Capacity: Stores a substantial volume of water underground, supporting irrigation, emergency reserves, or site water management needs.
• Low Profile Design: At 51'' tall, this tank is suited for sites where burial depth is limited, offering more installation flexibility than taller vertical tanks.
• Polyethylene Construction: Corrosion-resistant material designed for underground water storage applications.
• 2 Manway / Lid Access Points: Dual manways allow for filling, inspection, and routine maintenance without full excavation.
• Underground Environment Rating: Engineered specifically for below-grade installation, keeping stored water protected and surface space clear.
• Wide Distribution Network: Ships from multiple locations (MN, NY, OH, OK, UT, WA), supporting delivery across a broad geographic area.

This 1,425 gallon underground polyethylene tank is a practical solution for sites that need significant water storage capacity without above-ground footprint. Its low profile dimensions and dual manway access make it a workable choice for a range of buried water storage applications.
