This 530 gallon slimline water storage tank is built for above-ground use where space is at a premium but capacity cannot be compromised. Its narrow 25'' diameter profile lets it fit into tight corridors, along building walls, or in utility areas that a wider tank simply could not occupy, while still holding a full 530 gallons of water. Constructed from polyethylene and UV stabilized for outdoor exposure, it holds up in sun-exposed installations without requiring a covered enclosure.

The tank ships ready to connect, with a 16'' vented manway for access and inspection, one 2'' lower bulkhead fitting for drainage or outlet plumbing, and one 2'' upper bulkhead fitting for fill or vent connections. Built-in gallon indicators let you check water levels at a glance without removing the lid or using a separate gauge.

This tank is a practical choice for rainwater harvesting, irrigation supply, emergency water reserves, or supplemental storage at agricultural, commercial, or residential sites. Its slimline shape makes it especially useful when a standard round or vertical tank would be too wide for the available footprint. The polyethylene construction resists corrosion and does not require painting or coating to maintain its integrity above ground. Additional fitting configurations are available; contact us for details before ordering if your plumbing layout requires non-standard connections.

Key Features:

• 530 Gallon Capacity: Stores a substantial volume of water in a slimline form factor suited to space-constrained installations.
• Narrow 25'' Diameter Profile: The slim cylindrical shape fits along walls, in narrow utility runs, or in areas where a wider tank would not clear.
• UV Stabilized Polyethylene Construction: Resists sun degradation in outdoor above-ground applications without additional protective coatings.
• Included Fittings: Arrives with a 16'' vented manway, one 2'' lower bulkhead fitting, and one 2'' upper bulkhead fitting, reducing the connections needed to get the tank operational.
• Built-In Gallon Indicators: Allow quick visual level checks without opening the tank or using a separate measuring tool.
• Above-Ground Rated: Designed and specified for above-ground use, so no excavation or underground installation is required.

The 530 gallon slimline water storage tank is a well-suited solution for sites that need meaningful water storage capacity without the wide footprint of a conventional round tank. Its polyethylene build, UV stabilization, and included fittings make it a ready-to-install option for irrigation, emergency reserves, and general water supply applications.
