This 500 gallon low profile septic tank is built for underground installation where vertical clearance is limited, making it a practical choice for residential and light commercial sites that need reliable below-grade waste containment without the height demands of a standard upright tank. Constructed from polyethylene with an ANSI/NSF 61 approved resin, the tank is designed to hold up in buried environments while meeting recognized material safety standards for liquid containment.

At 48'' W x 97'' D x 42'' H, the low profile footprint fits sites where a taller tank would not clear overhead obstructions or soil cover requirements. A single 20'' gasketed manway provides the access point for inspection and service, and the non-plumbed configuration means the tank ships without pre-installed fittings, giving installers flexibility to connect the system to match site-specific plumbing layouts.

This tank is intended for underground septic applications and is sized for properties that need a 500 gallon single-compartment holding solution. The low profile design is particularly useful when burial depth is constrained by a high water table, rocky substrate, or site grading that limits how deep a tank can be set. Counter-buoyancy instructions are included to guide proper installation in conditions where groundwater pressure could affect a buried tank. Installers should review the attached low profile installation instructions before setting the tank.

Key Features:

• 500 Gallon Capacity: Provides substantial single-compartment holding volume suited to residential and light commercial septic applications.
• Low Profile Design: At 42'' tall, this tank fits burial situations where vertical clearance or soil cover depth is restricted, expanding viable installation sites.
• Polyethylene Construction with ANSI/NSF 61 Approved Resin: The tank material meets ANSI/NSF 61 resin approval standards, supporting safe use in liquid containment applications.
• 20'' Gasketed Manway: A single gasketed manway lid provides a secure, accessible service point for inspection and maintenance after installation.
• Non-Plumbed Configuration: Ships without pre-installed fittings, allowing the installer to configure inlet and outlet connections to match the specific site plumbing requirements.
• Counter-Buoyancy and Installation Guidance Included: Attached buoyancy and low profile installation instructions support correct underground placement, particularly on sites with groundwater considerations.

This 500 gallon low profile underground septic tank is a straightforward solution for sites that need reliable below-grade waste containment within a compact vertical envelope. The polyethylene build, gasketed manway access, and non-plumbed flexibility make it a practical fit for installers working with site-specific constraints. Review all attached installation and counter-buoyancy documentation before setting the tank.
